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.

Join Us for the Ocean Acidification Day of Action Webinar

The Coastal Acidification Networks (CANs) of the Mid-Atlantic, Gulf of America, Southeast, and Caribbean are pleased to host a webinar in recognition of Ocean Acidification Day of Action on January 8.

What is Ocean Acidification Day of Action? Ocean Acidification Day of Action was established by the NOAA Ocean Acidification Program (OAP) to raise awareness about ocean acidification and the significance of the global average seawater pH of 8.1. While seawater remains alkaline, the decline from approximately 8.2 over the past 250 years reflects a 26% increase in acidity, driven largely by increased atmospheric carbon dioxide. Now recognized as an international event, Ocean Acidification Day of Action highlights ongoing efforts to understand, mitigate, and adapt to the impacts of ocean acidification on marine ecosystems, coastal communities, and economies. For more information, visit the NOAA OAP webpage: https://oceanacidification.noaa.gov/2025-ocean-acidification-day-or-action/

Guest Speakers

Dr. Aurea Rodríguez Santiago, Founder and Director, Taller Ecológico de Puerto Rico

Dr. De’Marcus Robinson, Postdoctoral Fellow, Florida A&M University

Each speaker, alongside CAN coordinators, will deliver a 15-minute presentation highlighting their work and the actions they are taking to better understand and address the impacts of ocean acidification. The webinar will conclude with a public panel discussion and Q&A, creating space for dialogue on research, community engagement, and collaborative actions to advance ocean acidification awareness and solutions.

This webinar is open to researchers, managers, educators, students, and community members interested in learning more about ocean acidification and pathways for action.

The Intergovernmental Oceanographic Commission (IOC) of UNESCO invites all ocean acidification scientists to contribute to the sixth annual global ocean acidification data collection for the Sustainable Development Goal 14.3.1 Indicator: Average marine acidity (pH) measured at agreed suite of representative sampling stations. The Indicator highlights ocean acidification as a major stressor on marine ecosystems and the importance of global observations of ocean acidification to the sustainable use of ocean resources (Sustainable Development Goal 14).

All IOC Member States have agreed to submit data to this Indicator, where available. By submitting your datasets, you will increase the visibility of your own work both internationally and with your national government. An invitation for data submissions has also been sent to IOC’s International Oceanographic Data and Information Exchange Programme’s (IODE) National Oceanographic Data Centres (NODCs).

Background
In 2015, the United Nations adopted the 2030 Agenda and a set of Sustainable Development Goals (SDG), including a goal dedicated to the ocean, SDG 14, which calls to ‘conserve and sustainably use the oceans, seas and marine resources for sustainable development’. This constitutes an essential point of reference for IOC’s engagement with its Member States, as well as for its programmes at the global, regional and country levels. IOC was identified as the custodian agency for two SDG-14 targets and related indicators, namely ocean acidification (Target 14.3) and marine scientific research (Target 14.a). As the custodian agency, IOC was tasked with developing the methodology for the SDG 14.3.1 Indicator ‘Average marine acidity (pH) measured at an agreed suite of representative sampling stations’. IOC is further responsible to collect relevant data towards the indicator from Member States and to report the results to the United Nations.

Methodology
The SDG Indicator Methodology 14.3.1 provides the necessary guidance on how to conduct ocean acidification observation, using different types of technology and measuring different variables, including pH, carbon dioxide partial pressure [pCO2], total dissolved inorganic carbon [CT/DIC], and total alkalinity [AT/TA], as well as salinity and temperature. It further provides support on how to and what kind of datasets to submit to IOC, to ensure the production of quality controlled global, and possibly regional, products. The Methodology was developed in collaboration with IOC’s IODE programme, international ocean acidification experts (including data managers), and the Global Ocean Acidification Observing Network (GOA-ON).

Date and time: 9:00–15:30, Sunday, February 8, 2026
