Ocean Acidification

Dates: 30 November – 11 December 2026

Location: IAEA Marine Environment Laboratories, Monaco.

Deadline for application through InTouch+ platform: 6 November 2026

The Winter School is organized by the IAEA OA-ICC in partnership with the Prince Albert II of Monaco Foundation through the OACIS Initiative (Ocean Acidification and other ocean Changes – Impacts and Solutions) and the Laboratoire d’Océanographie de Villefranche (LOV).

Introduction

Ocean acidification is a global environmental stressor that threatens marine life and the livelihoods of coastal communities. Ocean acidification is caused by increasing atmospheric carbon dioxide being absorbed by the ocean, resulting in changes to seawater carbonate chemistry, including a drop in pH. Due to global concerns about its consequences, ocean acidification is included in international policies such as Target 3 of UN Sustainable Development Goal (SDG) 14 and Target 8 of the Global Biodiversity Framework (GBF).

The IAEA’s Ocean Acidification International Coordination Centre (OA-ICC) supports IAEA Member States to minimize and adapt to OA and report towards SDG 14.3 and the GBF, with a strong focus on building capacity to study ocean acidification and related stressors and promoting international collaboration and coordination.

Ocean acidification is not happening in isolation, but in combination with other human-driven pressures, including pollution, warming, and oxygen loss. The impact of multiple ocean stressors on marine life and ecosystem function is not well understood, yet this information is crucial to inform adaptation strategies that might minimize negative effects on organisms, ecosystems, and associated socioeconomic benefits.

The Fourth Winter School on Ocean Acidification and Multiple Stressors is part of the capacity building program of the OA-ICC.  This two-week training course will provide participating scientists with a thorough understanding about key concepts and experimental design used to study the impacts of ocean acidification in the context of additional stressors.

Objectives

The aim of the Winter School is to train early-career scientists who already have experience researching ocean acidification on how to study acidification in the context of other co-occurring stressors. Through lectures and practical exercises in the laboratory, the students will gain understanding of key concepts in multiple-stressor research (e.g., What is a stressor? What is a mode of action? What is an interaction?), purposeful experimental design, and analysis of complex datasets. During the course, participants will collaborate on a joint laboratory experiment to elucidate the effects of three simultaneous drivers on marine organisms.

Target Audience

The course is open to 10-12 trainees. Priority will be given to early-career scientists with experience in marine environmental change with a focus on ocean acidification; a background in biological sciences is preferred. At least one publication in the field of marine environmental change is required.

What happens when oceans change faster than the frameworks designed to manage them? Climate change is altering marine ecosystems, moving fish stocks, and increasing uncertainty for decision-makers. In this event, two researchers will share their knowledge on how climate change has an impact on the legal governance and management of ocean resources.

About the event (held in English)

Climate change is increasingly challenging the management and legal governance of marine resources by altering ecosystems, species distributions, and the assumptions on which existing governance frameworks are built. The North Sea and the Barents Sea, both highly productive and intensively managed regions, illustrate these pressures clearly.

Warming waters, changing ocean circulation, ocean acidification, and declining sea ice are reshaping marine ecosystems. In the Norwegian Sea, key commercial species such as  mackerel are shifting their distributions, In the Barents Sea, rapid warming and reduced ice cover allow boreal species to expand into traditionally Arctic areas, affecting species interactions in the ecosystem.  

These changes create a growing mismatch between dynamic ecosystems, legal governance  and fixed management boundaries. In the Norwegian Sea, complex international quota arrangements are strained as stocks move across national exclusive economic zones. In the Barents Sea, long-standing cooperative management faces new challenges as species distributions change and industrial activity increases. 

Climate change also exposes the limits of single-species management. Altered growth rates, recruitment, and species interactions make it harder to rely on historical data, strengthening the case for ecosystem-based and precautionary approaches. Overall, climate change places pressure on marine legal governance to become more adaptive, flexible, and forward-looking, requiring stronger international cooperation, better integration of climate science, and management systems designed for continuous change rather than stable conditions.

In this event, two researchers will share their knowledge on how climate change has an impact on the legal governance and management of ocean resources.

SS15 Ocean Acidification in the Caribbean and Latin America: Monitoring High-Risk Areas

Organizers
Jose Martinez, Caribbean Coastal Acidification Network
Debbie-Ann Gordon-Smith, Global Ocean Acidification Observing Network (GOA-ON) Caribbean Hub
Cecilia Chapa-Balcorta, Global Ocean Acidification Observing Network (GOA-ON) Latin American and Caribbean Network (LAOCA)
Jessie Turner, OA Alliance

Session Description
The Caribbean and Latin America are home to diverse landscapes and vital marine ecosystems that form the bedrock of the region’s economy, supporting over 700 million people. Unfortunately, decades of urbanization, continuous monoculture, and global climate change threaten to destabilize these ecosystems. One of these destabilizing forces is ocean acidification (OA), caused by excess atmospheric CO₂ entering ocean basins resulting in shifting ocean chemistry in the direction of lower pH. This stresses marine organisms, especially calcifiers like corals, making it harder to grow and maintain their shells and skeletons, risking key economic sectors like fisheries and tourism. While OA is a global phenomenon, there is significant variation in regional severity and impact, especially in coastal zones where local stressors, marine organisms, and hydrodynamics play a strong role in regulating carbonate chemistry.

This session will bring together presentations that highlight ocean and coastal acidification work in the Caribbean and Latin America, with particular emphasis on monitoring in high-risk areas. We define “high-risk” as locations where OA intersects with other stressors such as nutrient runoff, warming, deoxygenation and activities like coral restoration and shellfish aquaculture. Along the Latin American Pacific, upwelling of low-pH water creates chronic stress similar to recurrent Sargassum inundation events on Caribbean coasts, both of which can acutely exacerbate global OA. This emphasizes the importance of OA regional studies, as they create a scientific baseline to inform locally appropriate OA mitigation and adaptation strategies.

However, long-term monitoring and research in the Caribbean and Latin America have lagged behind those of other stressors. For example, only 34% of ocean professionals engaged in OA monitoring in the Caribbean measure two of the four OA parameters required to characterize a carbonate chemistry system (Grabb et al. 2025). A lack of low-cost sensors and/or complex laboratory methods that require specific training and expensive instruments likely drives this gap, meaning that the very studies we need are not occurring at the pace OA demands of us. All of this results in a disparity in how governments and coastal communities respond to OA’s local and regional impacts. Fortunately, many across the region have recognized this and moved beyond isolated efforts to establish regional networks driven by international frameworks dedicated to overcoming challenges like limited resources and technical capacity. These networks include the Global Ocean Acidification Observing Network (GOA-ON), that has a Latin American (LAOCA) and Caribbean Hub, IAEA Ocean Acidification International Coordination Centre (OA-ICC), the Caribbean Coastal Ocean Observing Systems (CARICOOS), and the Caribbean Coastal Acidification Network (Cari-CAN).

These networks have achieved success, including LAOCA’s recent session for young scientists on understanding the impacts of OA, CARICOOS’s MapCO₂ buoy (which has been gathering OA data since 2009), and the OA-ICC’s recent training course on monitoring OA in Jamaica. We must further leverage these networks to foment the creation of low-cost OA monitoring methods and strengthen the technical capacity of the region’s researchers. This would bridge the gap that governments and coastal communities need to manage, adapt, and mitigate the impacts of OA.

The Gulf is dynamic and productive, supporting corals, fish, shellfish and other marine life that sustain the region’s fisheries, biodiversity and economies. Join us for a Gulf of America Coastal Acidification Network (GCAN) webinar highlighting a new interactive Story Map that illustrates how researchers are monitoring ocean and coastal acidification across the Gulf. Pallavi Tummeti and Dr. Natalia López Figueroa will provide an overview of the Story Map and guide discussion about tracking acidification in the Gulf. Learn about the the data, research projects, and regional partnerships featured in this interactive resource.

Application Forms

Introduction
The Training Course on Ocean Alkalinity Enhancement — Assessing the Impact on Marine Organisms is part of the capacity building program of the IAEA Ocean Acidification International Coordination Centre (OA-ICC). The program aims to support IAEA Member States to minimize and address the impacts of ocean acidification (Sustainable Development Goal 14.3) and study the impacts of ocean-based solutions.

The course is organized by the IAEA OA-ICC in partnership with the Prince Albert II of Monaco Foundation through the OACIS Initiative (Ocean Acidification and other ocean Changes – Impacts and Solutions).

Objectives
The ocean is under pressure from warming, acidification and oxygen loss, adversely impacting marine ecosystems and the communities and societies who depend on them. But the ocean, covering 70% of Earth’s surface, can also be a vital part of the solution and our ally to mitigate and adapt to climate change. Meeting the objectives of the Paris Agreement to limit warming to well below 2º C would not only require drastic cuts in carbon dioxide (CO2) emissions, but also the active removal of carbon CO2 on the order of 100–1000 Gt CO2 over the 21st century (IPCC, 2018). Ocean alkalinity enhancement (OAE) is a marine Carbon Dioxide Removal (mCDR) approach which is receiving growing interest from scientists, policy makers and industry. It entails the addition of alkaline materials to the sea with the goal of increasing the ocean’s potential to absorb CO2. There is limited scientific information to date about the impact that OAE might have on marine organisms and ecosystems. Building technical expertise to assess ecological impacts of OAE is critically needed to allow for informed policy decisions about this approach.

The aim of this course is to train scientists on how to perform laboratory experiments on the potential impact of OAE on marine organisms. The course includes both theoretical and practical exercises with the goals of designing purposeful experiments, analyzing complex datasets, avoiding typical pitfalls, and ensuring data comparability with other studies. Lectures on the broader context and implications of OAE will also be provided (e.g., societal and governance aspects). The course will be largely based on the 2023 Guide to Best Practices for Ocean Alkalinity Enhancement Research, especially the chapters on experimental design.

Target Audience
The course is open to 10-12 trainees. Priority will be given to early-career scientists with experience in marine environmental changes who have already received training on ocean acidification and seawater carbonate chemistry. Preference will be given to applicants with experience in biological response research and who are interested in conducting studies on the ecological impact of OAE. At least one publication in the field of marine environmental changes is required.

Through this award, GCOOS will welcome a cohort of Gulf-region graduate students to attend the GCOOS Spring Meeting, the GCOOS 20th Anniversary celebration and allow them to participate in the workshop. Students will engage with scientists, managers, industry and educators during this event.

The full program of activities will be shared with the awardees prior to the meeting, but the workshop will include technical skills training, GCOOS Board Members’ panel and campus tour.

During the workshop, students will present at a poster session during the GCOOS Spring Members’ meeting & anniversary celebration on April 14, 2026, then join the GCAN workshop April 15 and 16. The workshop’s first day will focus on a technical core with applied tools in ocean acidification led by the GCAN steering committee chair, followed by a panel with GCOOS Board Members and then a working session designed to help students translate posters into a two-minute briefing for resource managers, stakeholders and general audiences using plain-language messaging. The final day will conclude with recording video summaries of the students’/postdoctoral researchers’ experience and tour of the Texas A&M campus.

Student Eligibility Requirements

• Currently enrolled in a graduate program or working as a year 1-3 postdoctoral researcher at institutions in Florida, Alabama, Mississippi, Louisiana or Texas;
• Be authorized to fly to College Station, Texas, to attend the meeting in person (i.e., visa is up to date);
• Have an interest in management, policy and/or research related to ocean and coastal acidification issues.

Student Responsibilities

• Attend full meeting in person (April 14-18, 2026);
• Present a poster on current work relevant to OA/COA or closely linked stressors (e.g., hypoxia, eutrophication, HABs, carbonate chemistry variability);
• Participate actively in the GCAN workshop and contribute to a short cohort deliverable (manager-ready synthesis, shared resource list, or student priority questions).

Join us for a timely discussion with OA Alliance members and partners.

As governments are being asked about marine carbon dioxide removal as part of broader climate strategies, clear guidance is needed to understand how mCDR intersects with ocean acidification.

On February 18, 2026, OA Alliance will release and discuss new support materials designed to help government members:
💧Navigate the links between mCDR and ocean acidification
💧Understand the current state of the science
💧Discuss desired outcomes, risks, and capacity needs related to mCDR strategies
