Partnershi for Observatlon of the Global Ocean CIO TIA POGO rt of the Trustees ForThe Year Ended 31 March 2025 OBJECTIVES AND ACTIVITIES Objectives and alms The charity aims lo bring together the worfd's major oceanographic institutes to plan joint actions to advance sustained ocean observations for societal benefit. POGO institutes are motivated by a common belief that advancing scientific understanding of the ocean is rooted in making 5y5tematic. high quality measurements. They believe that this underslanding and its wise use are critical to, and will make a real positive difference in, enabling humanity to develop a sustainable relationship with a healthy, productive and biologically diverse O￿an. POGO is further motivated by the shared belief that its vision can only be realised by working together across the worfd, where we can achieve togelher what none of us could do alone. The o￿an produces half of the world's oxygen, most of its fresh watèr and much of its food. It regulates climate and weather, is crÈtical to the cycling of heat, water and carbon. It is Ihe source of huge biodiversity. However, far too little is known aboLrt the statg and functioning ofthe ocean. Accordingly, scienlificalty sound study ofthe o￿an and support and advocacy for such study (and for the conclusions drawn from it) is ofvital importance to mankind. POGO seeks to expand intemational supportfor ocean observing, through innovation of the ocean observing 8yStern, Gapacity development and outreach18dvocaGy. In te￿n$ of innovalion, POGO members ar8 at the forefront of oceanographic methods and technology development, often In partnership with industry. Thus, POGO is in a critical posbtion to identify the emerging methods and technologies that POGO mernbers are developing and using, and highlighting those that can be expanded and deployed on a global scale to achieve global datasets obtained using comparable methoés. POGO also focusses on the affordability issues assoGi8ted with o¢ean obs8Ning. particularly for developing countries, and is therefore engaged in projects to develop low-wst sensors and systems for coastal O￿an obsejving. The societies and economies of many d8veloping countries rely heavily on the ocean, for example through coastal tourism, trade infrastructure, natural resource extraction, and small-scale and industrial fish8ri8s and aquaculture. However, extreme weather events, sea-level rise, tsunamis, harmful algal blooms and water pollution threaten the world's poorest and most vulnerable coastal and island communities. Ocean obseNalions and information services can be used to improve human health and safety and food security, support livelihoods and small-scale economic activities (artisanal fisheries and aquaculture, coa8t81 lourlsm), and Improve cllmate reslllence and dl3a51er risk reducllon. POGO also recognises that the expertise for conductlng ocean obseN8tlons Is not evenly distributed be￿een countries, and therefore th8 ocean is unevenly obsetved, with a much higher density ofobservations conductèd in Ihe North Atlantic and North Pacific, than in, for example, the South Atlantic, South Pacific and Indian Oceans. POGO therefore provides professional Iraining opportuni1188 for early-care8r sciéntists, mainly from coastal d8veloping countri8S, to expand the worldwide capacity for conducting sustained ocean obseryations, dats collection, analysi5 and management, and intèrpreting th8 Scientific results for the benefit of society. Msny actors, working together internationally, ar8 ne8ded to bring about sustainable management of the oceans that is informed by sound science, underpinned by a comprehensive global ocean measurement system. Thesé includa national governments, non-govemmenlal organisalions, the wider scientific community, funders of r8S8arch and monitoring programmes, and individual citizen5 working individually and collectively. POGO highlights the societal need for ocean observations, as well as the key issues facing global ocean obsejving, and the obstacles hampering the completion of a global ocean obseNing system, and brings these Issues lo the relevant stakeholder groups outlined above. The objects of the CIO Ére to advance the sciencè of global ocean observation for the public benefft, in partIC￿lar {but not exclusively) by: i. Advancing education in global ocean ObSe￿atIOn by identifying areas of further study for developing the science of global ocean observation., ii. The promotion of research in global ocean observation for the public benefit and the publlcatlon and dlsseminalion of the useful r8sults of such res8arch', iii. The provision of scholarships and research fellowships., iv. The promotion of innovation and technology in the science of global o￿an observation. In the short term. POGO aims lo provide training for early-career scientists, to develop the next generation of scientists and ocean obsetvers, as well as to rais& the lev8ls of awareness and education about the importance of the ocean and o￿an observing for society. Measures of success include numbers of trainegs, numbers of countries having received training. numbers of website visits and downloads of outrea¢h materials, mentions on social media and other statistics. The longer-terrn vision 15 to develop the capacity of research instilutions in developing countries to conduct o￿an observations, by (1) integrating the trained scientists and their institutions into th8 POGO network and having them actively participale in POGO projects, {2) sharing best practices among POGO member institutions, and (3) contributing to the development and dissemination of low-cost instrumentation for coastal oc8an observing. M8asur8s of success include numbers of POGO members and numbeis of new (developing) countries being added to the network, estsblishment of new oc88n obs8Ning systems in those countries, and demonstrated long-term impacts of Ihe training programmes (e.g. >5 years afl8r the training, on institutional capacrty and continued knowledge-transfer).

Advanclng educatlon In global ocean observation by identifylng areas of further study for dovoloping the science of global ocean observation.. this has been achieved by supporting Working Groups on specific tepics rèlated to ocean observation, such as Ihe Biological Observations WG. which led a proposal to the UN Decade of Ocean Science for Sustainable Development for an "Ocean Biornolecular Observing Ne￿Ork, IOBON). ii. The promotion of research in global ocean ob8ervatlon for the publlc benefit and the publication and di88emlnatlon of the usoful results of such research.. this has been 8chiev8d through POGO'S outreach and advocacy initiatives, through printed, on-line and social media, and participation in major UN Convention Meetings (COP29 Climate Conference and COP16 Biodiversity Conference). li. The provlslon of scholarships and research fellowshlps.. scholarships and fellowships have been provided to So early- career scientists for trainingleducation periods of belween 3 weeks and 10 monlhs during this financial year., iv. The promotion of innovation and technology In the gclence of global ocean observation.. this has been conducted mainly through two innovation projects focussing on developing low-cost instrumentation for ocean observing aimed at developing untries and citiz8n sci8nc8. More detalled Informatlon on these actlvllies can be found below, Ltnder the headin9 "Athlevement and Perfomance" Publlc benefit The trustees have complied with their duty, as set out in th8 Charities Act 2011. with regard to the public benefit guidance published by the Charity Commission. The CIO has been working towards achlevlng Its charitable oblectlves, dellverlng benefit to the wider publ1¢ through 5ts work to sdvance sustained ocean obseNations. Grantmaking POGO allocates some of its funds Irecelved from charllable foundatlons andlor memb8rship dues) to help support ocean observation activities {e.g. through Working Groups) and to provide training for eady-career scientists (generally in developlng countries). POGO has a set of policies and procedures for allocating such grants, which are summarised below. POGO issues a call to ils members, gen6rally once per year, for proposals for Working Groups, workshops, travel grants, training InllialSves and other artivities that are directly relevant to POGO'5 core mission, i.e. sustained, long-term ocean observing systems and shared use of infrastructure, data and information. This includes a template for applicants lo complete and submit lo the POGO Secretariat. Proposals musl b8 submitted by members of POGO. although participants can b& from oth8r institutes if necessary. If a Working Group or other initiative wishes to be funded for a second year, a request for extension must be submitted, using the template provided, by the same deadline as the new proposals. A sub-commillee of POGO members (who do not have wnf]icts of inlerest) reviews the proposals, according to a number of criteria, e.g. relevance to POGO'S Strategy and priority areas.. timeliness of Pfoposal,. adequacy of proposed deliverables and mileslones., adequacy of WGlproject membership (including geographic and gender balance). For training initiatives, the expected impact ol tho training and proposed methods for evaluating success are also taken into account. The Committee then makes recommendations to the Board ofTrustees on the proposal{sl to take fo￿ard, depending on the available budget. The availability of other funding sources is nol s determining faclor in the selection process. POGO and the Nippon Foundation have set up the NF-POGO Alumni Nelwork for the Ocean (NANO) to maximise the benefits lo the alumni from the training r8ceived and facilitate active contacts among the alumni. Through POGO, the Nippon Foundation funds modest regional and global research projects and publio outreach projects. PropDsals are received in response to an open call, and funding is renewed for successive years based on performance. The projects are selected according lo the following crileria.. (1) Projects should have an observationallapplied focus (not blue skies" researth) (2) They should have a societsl benefit focus (3) They should add value to and build upon exisling programmeslprojects (4) Funding should be used mainly for coordination (but also consum8bles, field work. modest equipment). (5) Projects should be coordinated by NANO alumni but participants can b8 a mixture of alumni and ext8rnal scientists. They should be supportèd by senior mentors and endorsed by the participating institutes, senior management. (6) They should include a minimum of￿0 different countries, preferably more. Page 3

IQOE is an international scientific programme to promote research. observations, and modelling to improve understanding of ocean soundscapes and effects of sound on marin8 organisms. IQOE is nearing th8 8nd of its 10-year life span and the IQOE Science Committee ISCI has been fccussing this year on IQOE'S final outputs, and on planning the projed's legacy and possible follow-up activities. Hlghllghts: The IQOE SC meeting was held in hybTid mode on 20-22 Nov 2024 in Reykjavik, Iceland. Meeting participanls reviewed ongoing IQOE activities, evaluated the progress of IQOE, and planned for the projacl sunset and legacy. Major outcome of the meeting was a decision to develop a projecl to follow IQOE that will focus on implementation ofthe O￿an Sound Essential Ocean Variable (EOV). The EOV specification sheet and Implementstion Plan were developed by 8 POGO-IQOE Working Group and supported by POGO funding, respectively. Discussions have begun with the Global Ocean Observing System (GOOS) of UNESCO'S Intergovernmental Oceanographic Commission (IOC) to apply for Emerging Ne￿Ork status for a global ocean 80und observing system. The Working Group on Low-cost Hydrophonés for Research, Education and Ciliz8n Science, chaired by Lucille Chapuis (University of Bristol, UK), has received a grant from POGO to design and produce prototypes of the low-cost hydrophones (see later section).

Integrate inlo global OA ob$eNing networks, such as GOA-ON, wlth the goal to share and make data avallable to Ihe global ocean observing community. Hlghlights: 1QOK USD obtalned from The Ocean Foundation (TOF) to purchase equipment to set lip the monitoring stations. Orders for eq¢Jipment and consumables have been placed, and one kit has been sent to the University of Ghana. The Ocean Foundation has continued to fund a Coordinator al the University of Ghsna to support BIOTTA. The BIOTTA Pl has been appointed Co-chair ofthe new GOA-ON Sub-Hub for W8sI Africa, with a colleague in Liberia.

There is a need to build capacity lo monitor human activities (e.g., pollulion) on banthic communiti8s and chemical tracers within the biota and sediment in the coastal waters of the Gulf of Guinea. The capacity building will increase access lo state-of-the-art sampling rnethodologies, laboratory pro￿$Se5, and inslrumenlalions useful for expanding the knowledge of benthic biodiversily and chemical tracers in biota coupled with the sediment in West Africa. a field poorly documented. Mercury is a toxic element occurring in low concentrations. but its by-producl, methylmercury, is highly toxic, and can accumulale in the sediment and biota (e.g., bivalves and fish). Page 7

Partnershi for Observation of the Global Ocean CIO TIA POGO rt of the Trustees For The Year Ended 31 March 202S STRATEGIC REPORT Achievement and performance Charitable activities (Continued) Benthic organisms ar8 good bioindicators for investigating anlhropogenic environmentsl dislurbances such as pollution, as species composition can reflect the ecological conditions Df an aquatic environment. Transitional waters (e.g., estuaries) are omplex systems that are regional in scale. There is limited information on transibon81 tropic81 waters and their biota in the regional inventory of benlhic fauna from West Africa. 5ncreasing human population coupled with growing demand for a resour and generation of wastes put coastal lagoons and estuaries at risk of collapse. Continuous monitoring of these systems is necessary for understanding changes in their ecosystem structure and functioning. Yet, there is inadequate infomiation on well- documented biological data and biota as chemical tracers of Contsminants from the tropical West African coast. Information on species occurrence, habit8t, and spatio-temporal distribution will allow local and regional distribution of indicAtor species to understand pollution and environmental change. 11 Is important to build the capacity of int8rdisciplinary scientists to help monitor and measure human Impacts on transStional and coastal waters. The BEACON working group aims to Contribute spatial knowledge on benthos and Hg contamination in biota and sediment from coastal waters in the Gutf of Guinea. The preliminary findings can support decision-making, policy development for biodiversity consèNation. future coastal benthic research, and understanding of pollution in tropical transitional coastal waters. Highlight8: The BEACON working group establish8d cooperation among interdisciplinary scienlisls in the Sub-saharan Africa region {Ghana, Cote d'lvoire, Nigeria, Togo and Benin) and working with international partnérs {UK, Germany and USA) through the creation of the BlochemiGal Observation Network (BON). The WG engaged in a seTies of seminars and meetings online for scientific knowledg8 exchanges and discussions among members on methods for adoption for biological sampling {e.g. benlhos and plankton) and dead remains of biological organisms Imicrofossils) analysis, chemical pollutants and m8rcury analysis via Direct Mercury Analyzer (DMA). The WG fostered working together by interdisciplinary scientists to sample soft substrate using bottom sampling gears (e.g., Eckman grab), plankton net for sampling plankton, Mulli-Paramet8r Probe to measure physical and chemical propertie6 of transitional water such as Volta Estuary, Ghana and u88 of Mercury Analyzer to measure chemical pollutanl such as Mercury (Hg) in sediment at the Unlversity of Ghana. The WG participated in field and laboratory wort for benthos, plankton, microf05siI and m8rcury analysis at the University of Ghana. Coastal Observin Lab in a Box COLaB Grant (10K EUR) awarded to the Unlversity of Ghana to host a training camp Many counlries worldwide face a signlficant hurdle In obtalning the necessary resources and knowledge to effectively monitor the coastal ocean. There is a common misconception th8t high end, 6xpensive equipment is needed to monitor and study the coastal oceans. COLaB breaks this belief by using cost 8ffective oceanographic instruments and methods backed by o￿aTr best practlC8S to collect a wide range of precise and accurate data. COL•B's modularity allows the user to tailor the paGkage lo fulfil their needs and to as51s1 answering their questions. Instruments will Gonsist of essential hydrographic instruments (current metei, CTD) as well as equipment for collecting water samples and anatysing crucial biogeoGhemical parameters (such as nutrients, chlorophyll. alkalinity, dissolved oxygen). It will also include planklon nets and other tools for conducting biological obseNaticns. In addition COLaB offers data handling and access solutions and downstream applications in the form of regional coastal modelling. Using various combinations of these package5, these observations have played a crucial role in moniloTing eutrophicalion and hamiful algal blooms, supporting fisheries management, establishing marine protected areas, and providing valuable validation and verification for models and retnote sensing data, Whenever feasible, these packages will incorporate Open-soUr￿ or homemad8 sampling gear and instruments, both in the field and for analysis purposes. COLaB comes with training suitable for the needs of the user. Hlghllghts: The grant from POGO supplernenled funds obtained through an Experiment.com crowd funding bid and enablèd a first COLaB "proof-of-concept. field exercise in Ghana in July 2024. Scientists from the COLaB team, from th8 UK and South Africa. joined a team from the University of Ghana in a study ofthe Pra River-estuary system. The Pra River, and othèr Ghanaian rivers, have been heavily affected in recent years by illegal gold mining being carried out upstream, which has resulted in massive sediment loads and mercury contamination that are heavily impacting dawnstream ecosystems and Ihe welfare and health of fishing communities. The objectives of the field exercise were to use a subsel of COLaB instruments and methods to demonstrate and provide training in the assessment Df river discharge arbd circulation (within the river and offshore), as w811 as sediment transport and physical and biog80chemical processe6 occurring across the estuarine salinity gradient.

Partn8rshl for Obseniatlon of the Global Ocean CIO TIA POGO Re ort of the Trustees For The Year Ended 31 March 2025 STRATEGIC REPORT Achlevement and performanco Charitable activities {Continuedl Over 8 days, river discharge was determined by conducting a flow and bathymetry river transect using simple hand-held flow meters and depth finders. Current measurernents were made with drifters and acoustic current meters (fixed-depth and profiling) and waler structure and mixing were assessed through CTD profiling across the estuarine salinity gradi8nt. S8veral chemical analyses (nutriènts. pigments. and dissolved organic matter) werè conducted on water samples collected across the same gradient. Finally. suspended sediment samples were collected to detemine mercury concentrations. Notsbty, the field and lab work also allowed the WG lo test newly developed affordable instruments (CTD. colorimeter, and fluorimeter) against commercial counterparts. Most analyses have been completed, and the WG 16 now in the proces8 of working up the CTD, discharge, and current data. These, alongside sedim8nt load and m6rcury r8sults, will bé modelled to provide a first assessment of the fale of sediment and mercury discharged from the Pra. This should be completed by July 2025. An EOV and Im act-Based Bounda Currents Ocean Obs8Nin Grant (1 OK EUR) awarded lo Soulh African Environmental Observation Nelwork (SAEON) to 8UPPOrt a wotkshop and publication of WOTkshop report The Ocean plays a unique role in the complex system of the ocean, influencing the weather, climate, ocean circulation, global carbon cycle, and extreme weather patterns. Pressing societsl needs for infomiation 8nd servic8s require a ré-assessment of the current system and a co-designed plan to malure the observing system to meet user needs. Boundary currents directly inlluence the understanding of regional weather systems, significantly impact marine heatwaves and Iropical wclones and impact the local f18heries and aquaculture. The purpose of this worf(shop was to create an oveNiew of observations and modelling efforts already ongoing within the Agulh8S Current, develop priority gap areas and thus observational requirements and a resulting start to the development of a backbone design of an O￿an observing system to better understand key fealures in the Agulhas Cuffent region. The workshop also aimed lo determine potentlal overlaps and opportunities for other key features to be considered In the design for monitoring and assessment purposes including (but not limited to) tropical cyclones, fisheries and maiine heatwaves, all of which impact or are imp8cled by the Agulhas Current under a changing climate. Hlghllghts: Stakeholder mapplng.. The worf(shop allowed for a number of key partlcipanls to dlscuss challeng8s In understanding the Agulhas Current and adjacent regions in terms of their knowledge base (researchers and modellers) and industry (fisheries, search and rescue}.

These phenomena have a strong impact at the global, regional, but also local levels. MHWS have become an increasingly serious threat not jusl from the perspective of pelagic and benthic ecology on the continental shelf but also for coastal aquaculture and fisherles, as demonstraled by many reports of fisheries closures from around the world caused by MHWS, Estuaries, in particular, represent environmenls with high produ¢tlvlly and blodiverslty that sustain important economic activities like aquaculture and fisheries. While our understanding about th8 causes, impacts, duration and ext8n8ion of MHWS has increased signific8ntty during the last 10 years, this information has mainly come from large scale studies of the global or regional oceans. This large-scale perspective 18 infomied by climate rnodels and rernote sensing as the main data sources, which are unable lo spatially resolve smaller coastal systems such as estuaries and bays, To gain insight into the coastal response to MHWS, this group proposes a different approach, combining in-situ obseN8tions, ￿mote sensing and high-rasolulion modelling in the coastal zone. The geographic intercomparison will contribut8 to a b8tter understanding about the impact of MHWS on the global coastal areas and the potential implications under climate change scenarios. The WG alms to develop an active collaboration and coordination to highlight the irnportance and n8C8ssity of studying the implications and consequences of MHWS in coastal areas. So far. the impad of MHWS in coastal areas has been evaluated in few recent papers- however. our WG is mullidisciplinary, including coastal ecologists, coastal modellers and climate scientists. Hence, th8 distinctive feature of this group is its special focus on the shallow continental shelf, its interdisciplinarity, and its interesting geographic diversity (Canada, North America's east and west Coasts, South America's west coast. Australi8'S SOUth8ast coast, Mediterranean Sea, Antarctica's glacial embayment's). Hlghllght8: The Coastal Marine Heatwave Interdisciplinary Research group (CMHIR, httP8'.Ilcoastalmhw.0rg4 successfully organized the Workshop: Marine heatwaves dynamics and impscts on eo8Stal and estuarine ecosystems at the University of Concepcion (Chile), from 9-11 April 2024.

Naturally, this brings with it a lot of environm8ntal pr8ssure and risks to existing natural habitats. However, there are still very special pockets of marine habilals thai possess high diversities of marine life such as shallow seas, intertidal mudflats, uninhabiled islands and seagrass beds. The Middle Bank (northern Straits of Malacca) - an area of rich s8agrass community was chosen to study its changing evolution in an evolving dimalic and anthropogenic influencè, The Middle Bank seagrass m8adow serves as nursery ground for many commercially important fish and mollusc species, supporting small-scale fisheries using artisanal fishing gears by local coastal communiti8s. CEMACS has been working closely with Penang State Government to gazette this area as ecologically important, serving as a carbon sink (complemènting adjacent mangrove area) to mitigate climate change and offset the state's carbon emission. The proximlty of the Middle Bank to a World Heritage Site Gan help drive awareness and education on the value of th8S8 marine habitats to the general public. The objective is to encourage the local govemment and agencies to sel up a marine protected area for research, monitoring and education. Highlights: CEMACS conducted the Marine Field Course.. Biodiversity & ConseNation for a group of college students from Kolej Yayasan UEM, Selangor (23- 26 Feb 20241. 35 sludents were introduced to ecological techniques, microscopy skills, aquaculture basics and introduced to the 8eagrass ecosystem. The group was exposed to the seagrass ecosystern and learnt how transect lin8s are Used along with quadrats to measure and monitor the life forms in this habitat. Students learnt about the various species inhabiting th8 seagrass bed, the intricate web of ecological relationships. and the critical role seagrasses play in maintainlng a healthy marine environment. This experiential leaming opportunity broadened students. und8rstanding of marine ecosystems and fostered an appreciation for the need to preseNe and prolect these habitats. Moreov8r, the visit provided a chance for studenls lo actively participate in local conservation efforts, contributing to the sustainable management of Pulau Gazumbo's marine resources, A book, "Tides of Change: Th8 Middle Bank Marine Sancluary and the Quest for a Reslllenl Penang" was published, underscoring the collaborative efforts of scientific, governmental, and community Stakeholders in the envSronmental resloration and pToteclion of the Middl8 Bank. The book aims to Inform, inspire, and e811 for action to preserve Penang's treasured natural sanctuary. A stakeholder engagement workshop was held In two phases.. the fSrsl wlth fishermen and operalor5, and the second with government agencies and other stakeholders. The workshop addressed activities allowed and prohibited within Ihe sanctuary, adhering to IUCN guidelines for protectèd area managemant C8legories, ensuring comprehensive understanding and agreement on the sanctuary's Management. Additionally, a field visit to th8 Middle Bank was organized for Ex8CUtive Council {EXCO) for Environment for Penang State, YB Sundarajoo and the state government team to familiarize them with the upcoming eslablishment of the marine sanctuary. This visit, which included the northern shore of the Middle Bank, Pulau Gazumbo Kecil, and Pulau Gazumbo Besar, fostered a positive response towards the sanctuary's establishment, reinforcing the commitment to environmental conseNalion. A beach cleanup activity is planned 81 the Middle Bank area, aiming to engage the communily and stakeholders in preserving the sanctuary's natural beauty and ecological health.

Partnershi for Observation of the Global Ocean CIO TIA POGO ort of tho Truste8s For The Year Ended 31 March 2025 STRATEGIC REPORT Achiovement and perfomiance Charitable activities (Continued} Marine fish8s are an excellent focus point for marine rnolecular biodiversity assessment as standardized methods for reference documentalion are availab18 and fisheri6s have a huge importance for human nutrition. This is particularfy true in Wesl Africa, where small-scalè artisanal fisheries contribute signrficantly to livelihoods. and poverty reduction. The objective of the training was to deliver practical lab and bioinformatics skills on a small and inexpensive DNA sequencing device, the MinlON flongle from Oxford Nanopore Tethnologies, to generate reference DNA barcodes. The delivered knowledge will empower researchers and mulliplicators from various Wesl African counlries to monilor their marine biodiversity on their own, without the need for inl8malional cooperation. Although this training was focused on the generation of a reference DNA barcode datsbase, the same protocol can be used to then monitor biodiversity wilh eDNA. Participants participated in parallel aclivrties involving wel lab work and theory. Each participant was involvèd in DNA extraction, MinlON budget calculations for proposal writing, indexed primer and demultiplexing worktlows, as well as a sÈri&s of introductory discussions in English and French. The sequencing from related lab activities produced nearly 171 COI barcodes from marine fish. After the successful conclusion of the training, participants underscored the pracliGal value of hands-on sequencing Iraining and the WAMBA-Net.

The training aimed to enhan￿ participants, data analysis skills using tools like Ocean Data Wiew (ODV), R, and QGIS, as well as provide participants with guidelines for sGienlific writing. The Course aimed lo provide basic concepts of fundamental ststistics and advanced oceanographic data analysis using R, along with oceanographic dats visualization with ODV and Other GIS So￿are. The onllne sessions consisted of bolh lectures and hands-on sessions. There were four lectures on oceanographiG data and six hands-on sessions on O￿an0graphiC data analygis. The online sessions began with a ledure on Essential O￿an Variables.. Insights for Oceanography, f¢xusing on the importance of Essential Ocean Variables (EoVs> in understanding ocean processes, supporting tsrgel8d r8S8arch, and driving advancements in oceanography. The second lecture focused on the Importanc8 of Data Sharing and Management in Marine Policy, discussing the importance of data sharing, sharing plafforms, and the application of different techniques in oceanographic data management. The third lecture, on Data Govemance and its Role in Marine Policy, highlighted th8 need for cornprehensive data to develop effective policies, the role of dats govemance in ensuring data usability and security, and the development and implementation of policies related lo data management for Marine Spatial Planning {MSP). The fourth lecture focused on Open Sourc8 Oceanographic Data, which highligh18d the collection and application of oceanographic data from different open-access sources. The in-person sessions of the training included 10 sessions. Two sessions focused on data visualization with ODV, five sessions on oceanographic data analysis using R, two sessions on scientific writing, and one session for group presentstions by participants. From the feedback suNeys conducted, it was apparent that key useful elements of the training included hands-on aclivities, statistiC81 analysis with R, oceanographic data analysis, and scientific writing. Participants valued the friendly and expert guidance of instructors, effective individual attention, and logistical arrangements like proper breaks. Real-life examples, peer interactions, and the practical applicalion of tools such as visualizalion techniques were also seen as valuable, enriching the leaming experience. Overall, the emphasis was on interactive, well-sltuctured, and practical sessions linked to their academic and research needs. ObJeGt 4: The promotion of innovation and technology in the science of global ocean observation: This has been conducted mainly through projects focussing on developing low-cost inslrumentalion for ocean observing aimed at developing countries and citizen science.

SAGITTA The project aims to implement a citizen science approach for consistent and regular lemperalure profile data colleGlion in the coastal ocean. This requires distribution of cheap and simple temperature-deplh (TD) probes among the general public. Though suitable equipment is pr8sent on the market, it is very expensive (5.000-9,000 USD per probe) and rèlatively eompiex for users without specialised training. ThÉrefore the project aims to crèate a low-cost TD probe, simple smartphon8 application and web portal to make this idea possible. The probe should be inexpensive (about 100 USD), yet scientifically reliable. The smartphone app will be used for probe control, instanl data visualization and data transmission to th8 web. Thè web portal is necessary for data storage, acGes5 and dissemination- it will also be useful for training and outreach. A field test of the water temperature profiler was conducted in August 2024 in Haifa Bay.18rael. The instrument was deployed using a 6Ckmetre rope and a heavy anchor (approximately 3 kg). The vessel departed from Kishon Marina, and the profiler was deployed at d8plhs of 50 metres and 30 metres at different locations. Temperatur8 readings were recorded at intervals of 220 milliseconds, Overall, the profiler successfully Gapturèd lemperalure profile5 at varying depths, However, no themiocline was detected, contrary to initial expectations. For future deployments, it will be important lo address the noise generaled by the pressure sensor and irnprove its calibration. Enhancing sensor calibration and reducing associated noise will contribLrte to greater measurement accuracy and provide more rellable data for future sea trlals. During the first semester of 2024 it was agreed that the proje¢l leadership should be transferr@d to Dr. Subrata Sarker. NANO-DOAP coordinator, bringing NANO-DOAP and SAGITTA projects together.

Wthile th8 charity has made 8 loss for the year of £146,843, the majority of this has been due to utilising restricted reseNes brought forward. Total reserv8s are £341,079 and taking into account restricted reserves of £49,707, this leaves £291,372 unrestricted resetves. Principal fundlng source8 The principal sources of funding are.. Membership dues.. these are used to cover all operalional costs of the eharily as wèll as some grants and fellowships Grants from charitable foundalicns and other organisations, notably the Nippon Foundation, which supports POGO'S capaclty development programme, the Minderoo Foundation, which has supported an OBON workshop on biomolecular methods for fisheries management, and the Scientlfic Commiltee on Oceanic Researth (SCOR), which co-funds the POGO-SCOR visiting fellowship programme. An Agreement was also signed durlng this fiscal year with O￿anQueSt, a Saudia Arabia-based philanthropic foundation. Reserves policy POGO'S reserves poliw was adopted in Jan 2020. The target minimum Operating Reserve Fund is 12 months of average operatlng costs, The calculation of average monthly operaling cosls includes all recurring, predictable expenses such as salaries and benefits, insurance, office, travel, communications, projects, Working Groups and capacity development programmes. Depreciation, in-kind, and other non-cash expenses are not included in the calculation. The calculation of average monthly expens8s also exclud8s one-time or unusual, capital purchases. The Operating R8seNe is intended to provide an intemal source of funds for situations such as a 6udden increase in expen88s, one-tirne unbudgeted expenses, unanlicipal8d loss in funding, or unlnsured losses. Operating Reserves are not inlended to replace a permanent Ios5 of fvnds or eliminat8 8n ongoing budget gap. It is th8 intention of POGO for Operating Reserves to be used and replenished within a reasonably short period oftime. Th8 Operating Reserve Fuftd is defined as a fund set aside by action ofthe Board of Trustees. The minimum amount to be set aside as Operaling Reserve will be established in an amount sufficient to maintain ongoing operations and programmes for a set period of time, measured in month5. Th8 Operating Reserve serves a dynamic role and will be reviewed and adjusted in response lo bolh Internal and external changes. The amount of the Operating Reserve Fund target minimum will be calculated each year 8ft8r approval of the annual budget, reported to the FinanGe CommitteelBoard of Trustees, and included in the regular financial reports. The Operating Res8rve will b8 funded with surplus unrestricted operating funds. The Board of Trustees may from time to time direct that a specific sourc8 of revenue be set aside for Operating ReseNe. The main contingencies allowed for by the Reserves Policy, ar8: POGO having to relocate Ihe office, in case the agreement in place with the current Secretarial host(s) is leminated by eilher party. Th8 provision in the conliact is for 6 months, notice, which would mean any costs incurred would have to be m8t at relatively short noti￿, Costs Could include redundancy and other compensation that POGO may be required by law to pay the staff (e.g. related to the Transfer of Undertakings (Protection of Employment) -TUPE', legal cosls-, potential increased salary costs related lo employment by a different host, etc, If POGO were to start employing the Secretariat slaff itself there would be additional cosls related to HRIIT and other Servi￿$, office rental elc. Other emergencies including legal costs, insurance ex￿$$, or uninsured losses. Loss of income: This is a potsntial threat caused by fluctuations in membership. or by some members being unable to pay their dues in a given year. In addition. the Nippon Foundation grant is only renewed from one year lo the next, so rf it is not renewed w8 would potentially receive very little notice of this (in this case th8 project would not go ahead, bul additional fvnds from POGO could potentially be needed to cover staff costs, lo which NF contributes £50,000 per annum). The amount of reseNes currently held is projected to be very slightly above the amount staled in the rese￿eS policy. taking into account commitments that have been made to fund Working Groups and projects, but which have not yel taken plac8. The balance held as unrestric18d funds al 31 March 2025 was £291,372 ofwhich £291,372 are considered 'free' reserves. This level ol reserves is broadly consistent wilh our policy Df holding one years, operating costs (Circa £250,000), excluding Nippon related projects. Page 16

Partnershl for Observation of the Global Ocean CIO TIA POGO Re ort of thè Trustees For The Year Ended 31 March 2025 STRATEGIC REPORT (continued) Financial and risk management objectives and policies The trustees have a duty lo identify and review the risks lo which the charity is exposed and to 8nsure appropriate controls are in place to provide rèasonable assurance against fraud and error. The trustees recognise that risks can arise not only from the charity's activities but also from failure to act or exploit opportunit18s. The trustees do not consider that all risks should be avoided. They are not averse to taking reasonable risks as part of their strategy to achieve the charity's objectives. However, they wish to be made aware of the major risks the charity faces so that they can plan how lo manage those risks and mitigate their effects. The trustees have therefore appointed the Chair and CEO lo review major risks and make recommendations to the trustees as to how to manage th8m. Th8 truste6s exp8Ct all members, staff and volunteers when engaging in any activity to consider th8 risks it poses and to aot in accordance with any recommendations made for risk management. Th8 Iruste6S expect that staff and volunteers will not engage in significant types of aGtivity which are not similar to activities the trustees are already aware of, without first having made to the trustees a proper proposal for the charity engaging in such activity, including an analysis of the risks such activity might pose to the charity. The trustees have the same expectation in relation to significant increases in activities already pursued by the Gharity or significant changes in the way Ihose aclivitie5 are pursued. Risk management will be conducted according to the following steps: (1) identify the risks, {2) assess the risks, (3) evaluate what action needs to be taken, (4) monitoring and assessment. The trustees have developed and approved a risk management policy and a risk register to identify and assess the potential risks and develop strategies to manage Ihem. The risk register is reviewed monthly by th8 Chair and CEO, and twice per year by the Board as a whole. Given the charity is relatively young, it has not had a great deal of time lo develop a malure'rlsk appetite. approach. It is the intention of the Charity for Trustees to engage in 'risk appelile, training with a view to developing a measured approach to risk.

An External Review Panel, consisting of 6 experts, was appointed by the Board ofTrustees. The Panel members were selected to represent a range of POGO stakeholders, including the marine science community {POGO members and non-members), representatives of other international or regional organisations, and other stakeholders. The Panel met several limes on-line, as well as during a hybrid meeting in Plymoulh, UK, where they also had the opportunity to interacl with the POGO Secretariat and former Chair. One member ofthe Panel also attended the POGO Annual Meeting to interact with Ihe POGO community {members, trustees, alumni, partners...). Members of the Panel received travel support to attend the POGO-25 Annual Meeting (1), or the Panel Meeting in Plymouth (4). and four ofthem reGeived a modest honorarium as compensation for their work (the other were not allowed by their employer to receive any paymenll. The POGO Board of Trustees was presented the External Review Panel's report by the Panel Chair, Wendy Watson-wright, on 20th June 2024. The report and its recommendations were discussed by the Board during the subsequent meeting, and some proposals were put to the membership on 29th August 2024, during an on-line meeting attended by over 30 members. Wendy Watson-wrighl also presented the report at that m88ting and answered questions from the members. The Panel's recommendalions focused on the following areas..

Re ortof the Indo endent Auditors to tha Trustges of Partnershi for Observation of the Global Ocean CIO Opinion We have audited the financial statements of Partnership for Observation of the Global Ocean CIO (the 'Charity') for the year ended 31 March 2D25 which comprise the Statement of Financial Activilies. the Statement of Financial Position, th8 Statement of Cash Flows and notes to the financial statem8nts, including a summary of significant accounting policies. The financial reporting framework Ihal has been applied in their preparation is applicable law and United Kingdom Accounting Standards (United Kingdom Generally Awepted Accounting practi￿>. In our opinion the financial statements.. give a true and fair view of the state of the Charity's affairs as at 31 March 2025 and of its incoming resources and application o resources, including its income and expendilurè, for the year then ended-, have been properly prepared in accordance with United Kingdom Generally Accepted Accounting Practice., and have been prepared in accordance wilh the requirements of the Companies Act 2006. Bas18 for oplnlon We conducted our audit in accordance with Intemational Standards on Auditing (UK) (ISAS (UK)) and applicable law. Our responsibilities under those stsndards are furth8r described in the Auditors, responsibilities for the audit of the financial statements section of our report. We are independent of the Charity in accordan￿ with the ethical requirements that are relevant to our audit of the financial statements ir) the UK, including the FRC'S Ethical Standard, and we have fulfilled our other ethical responsibilities In accordance with these requirements. We believe that the audit evidence we have oblained is sufficient and appropriale to provide a basis for our opinion. Concluslons relatlng to going concern In auditing the financial statements, we have concluded thÉt the trustees, use of the going concern basis of accounting in the preparation of the financial statements is appropriate. Based on the work we have performed, we have not IdentSfled any malerlal un¢ertalntles relating to events or conditions that, individually or collectively, may cast significant doubt on the Charity's ability to continue as a going concem for a period of al least tsvelv8 months from when the financial statements are aulhorised for issue. Our Tesponsibililies and Ihe responsibilities of the trus1888 Wlth respect to going concem are described in the relevant sections of thls report. other information The trustees are responsible for the other information. The other information comprises the information included in Ihe Annual Report, other than the financial statements and our Report oflhe Independent Auditors Ihereon. Our oplnion on the flnancial statements does not cover the other infomation and, except to the extent otheNlse expllcllly stated in our report, we do nol express any form of assurance conclusion thereon. In connection with our audit of the financial statements, our responsibility is to read the other information and, in doing so, consider whether the other infomialion is malerially inconsistent with the financial statements cr our knowledge obtained in the audit or otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether this gives rise to a material misstatement in the financial Statements themselves. If, based on the work we have performed, w8 conclude that there is a material misstat8m8nt of this other information, we are required to report that fact. We hav8 nothing to report in this regard. Matters on whlch we are requirpd to report by exception We have nothing to r8POrt In respect of the following matters where the Charities (Accounts and Reports) Regulations 2008 requir8S US to report lo you if. in our opinion.. the information given in the Report of th8 Trustees is inconsist8nt in any material respect with the financial slatements., or Ihe Charity has not kept adequat8 accounting records; or Ihe financial statements are not in agreement with the accounting reGords and returns- or we have not received all the information and explanations we require for our audit. Responslbilities of trustees As explained more fijlly in the Stalement of Trustees, Responsibilities, the trustees (who are also the directors of the Charity for the purposes of company law) are responsible for the preparation of the financial statements and for being satisfied that they give a true and fair view, and for such intemal mntrol as the truslees determine is necessary to enable the preparation of financial statements that are free from material misstatement. whelher due to fraud or error. In preparing the financial statements, the trustees are responsible for assessing Ihe Charity's ability to continue as a going concern, disclosing, as appliGable, matters related to going concern and using the going concem basis of accounting unless th@ Irustees either intend lo liquidate the Charity or lo cease operations, or have no realistlG alternative but lo do so.

Re ort of the Inde ndént Auditors to the Trustees of Partnershl for Observatlon of the Global Ocean CIO Our responslbllltles for the audit of the financial statements Our objeclives are to obtsin reasonable assuran￿ about whether the financial statements as a whole are free from material misstalement, whether due to fraud or error, and to issue a Report of the Independent Auditors that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducied in accordance with ISAS (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material rf, individually or in the aggr8gate. they could reasonably b6 expecl8d to influencè the economic decisions of users taken on the basis of Ihese financial slatemenls. Irregularities, including fraud, are inslanGes of non-compliance with laws and regulations. The exlenl to whith our procedures are capable of detecting irregularitie5, including fraud, is detailed below. The obj8Ctives of our audit, in resped lo fraud, are.. lo identify and assess the risks of material misstatement of the financial slalements due to fraud,. to obtain sufficient appropriate audit evidence regarding the assossed risks of material misstatement dua to fraud, through designing and impl&menting appropri8te respons8s'. and to respond appropriat8ly to fraud or suspected fraud identified during the audil. However, the primary responsibility for the prevention and detection of fraud rèsts with both those charged with governance of the entity and ils management. Our approach was as follows.. -we id8ntified areas of laws and regulatlons that could reasonably be expected to have a material effect on the financial statements from our general commercial and sector experience, and through discussion with th8 directors and other management (as required by auditing standards). and discussed with the directors and oth8r management the policies and procedures garding compliance with laws and regulations. -we identified the following areas as those most likely to have such an effect.. health and Safety,. General Data Protection Regulation (GDPR),. fraud,, bribery and corruption and employment law. Auditing standards limit the required audit procedures to identify non-compliance with these laws and regulations to enquiry of the trustees and other management and inspection of regulatory and légal correspondence, if any. -we considered the legal and regulatory frameworks directly applicable lo the financial statements reporting framework (FRS 102 and the Companies Act 2006 and the Charities Act 2011) and the relevant tax compliance regulations in the UK., -we considered the nature of the group's operations, the control environment and business performance, induding the key drivers for management's remuneration., -we communicated identified laws and regulatlons throughout our team and remalned alert to any Indlcations of non<ompllanGe throughout the audit., -we consid8red the procedures and controls that the group has established to address risks ident5fied, or that otherwlse prevent. deler and detect fraud., and how senior management monitors those programmes and conlrols. Bas8d on this understanding we designed our audit proc8dures to identify non-compliance with such laws and regulations. ￿ere the risk was wnsidered to be higher, we performed audit procedures to address each identified fraud risk. These procedures included.. testing manual joumals., reviewing the financial statement disclosures and testing to supporting documentation,. performing analytical procedures., and enquiring of management, and were designed to provide reasonable assurance that the financial statements were froa from fraud or error, Owing to the inh8rent limitations of an audit, there is an unavoidable risk that we may not have detected some material misstalements in the financial statements, even though we have properly planned and performed our audit in accordance with auditing standards. For example, the further removed non-compliance with laws and regulalions (l￿egUlarIt￿eS) is from Ihe events and Iransaclions reflected in the financlal stalemenls. the less1Skely the inherently Ilmiled procedures required by auditing 8tandards would identify it. The risk is also greater regarding irregularities occurring due to fraud rather than error, as fraud involves inl&ntional concealment, forgery, collusion. omission or misrepresentation. We are not responsible for preventing non- compliance and cannot be expected to detect non-complianc8 Wlth all laws and r8gulations. A further description of our responsibililies for the audit of the financial statements is located on the Financial Reporting Council's website at www.frc.org.uklaudilorsresponsibilities.
