Ocean Acidification

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).

Title of the event: Designing multiple driver experiments

Conveners: Sinéad Collins, University of Edinburgh, Simin Gao, University of Edinburgh, Paul Renaud, Akvaplan-niva

Description: The MEDDLE resources were developed to help researchers design and carry out tractable and comparable multiple driver experiments. In this workshop, participants will learn how to use these resources to design multiple driver experiments. While the concepts and methods discussed can apply to many systems, examples used during the workshop will focus on manipulative experiments rather than observational data.

The workshop is geared mainly towards PhD students, postdocs, and ECRs new to multiple driver research, and focuses heavily on the rationale of different experimental designs, and analysis strategies for multiple driver experiments. A basic working knowledge of statistics is needed (regression analysis), and statistical analysis examples will use R. Participants should bring a laptop with R and R studio installed.

Topics include:

• Defining a research question
• Identifying relevant drivers
• Identifying biological traits and responses
• Experimental designs for multiple driver experiments
• Statistical analysis plans

Hosted by the SCOR project “Changing Ocean Biological Systems”, this free workshop will be led by Sinéad Collins, University of Edinburgh (UK), Simin Gao, University of Edinburgh (UK), Paul Renaud, Akvaplan-niva (Norway). Spaces are limited. If you would like to attend, contact Sinéad Collins (s.collins@ed.ac.uk) or fill out this form by January 15, 2026 to register your interest. Limited to 24 people, so please register early!

Please include a brief (<150 words) statement outlining (a) your experience carrying out Ocean acidification or multiple driver experiments (if any) and (b) how you plan to incorporate multiple driver experiments into your work.

Ocean acidification, the progressive reduction in seawater pH caused by rising atmospheric CO₂, represents one of the most pressing threats to marine ecosystems. By altering the carbonate chemistry of the ocean, it compromises the ability of calcifying organisms, such as corals, shellfish, and some plankton, to build and maintain skeletons and shells, with cascading effects on biodiversity, fisheries, and coastal communities. Understanding and monitoring these changes is essential to predict impacts, guide mitigation strategies, and support resilient management of marine resources.

This talk will explore different methods of ocean acidification monitoring, highlighting approaches from historical reconstructions to cutting-edge autonomous sensing. Paleo proxies, such as the chemical composition of coral skeletons allow us to reconstruct long-term trends in pH, providing context for current changes and identifying natural variability over centuries. Building on these foundations, in situ measurements using traditional shipboard sampling have offered high-accuracy snapshots of carbonate chemistry, but remain limited in temporal and spatial coverage.

Recent advances in autonomous sensing now allow continuous, high-resolution monitoring of Essential Ocean Variables across a range of ecosystems from shallow coral reefs to the deep open ocean. Lab-on-chip sensors, capable of measuring pH, alkalinity, and other key parameters, provide unprecedented insights into the dynamics of marine carbonate chemistry under natural and anthropogenic stressors. These technologies have been deployed across several platforms, including research vessels, moorings, commercial operations subsea vehicles of opportunity, revealing how biogeochemical processes respond to environmental variability.

The talk will also highlight the practical application of these tools through capacity-building efforts in Small Island Developing States. By providing monitoring kits and training local stakeholders, these programmes support locally driven data collection, enhancing understanding of ocean acidification in regions highly vulnerable to climate change. Partnerships with industry have further enabled the translation of research into operational tools for sustainable marine management. Bringing these approaches together highlights both what we understand about ocean acidification and where improved observations are still needed. The talk will reflect on the progress made so far and the opportunities that new tools and partnerships provide for expanding future monitoring efforts.

We invite abstract submissions for our session at the World Conference on Marine Biodiversity 2026 (Bruges, 17–20 November 2026). Ocean acidification (OA) is progressing rapidly, yet its ecosystem- and biodiversity-level consequences remain insufficiently understood. This session will bring together researchers working on OA and experts in marine biodiversity assessment to discuss current knowledge, emerging techniques, and strategies to evaluate and minimize OA impacts.

We welcome contributions from laboratory, field, natural analogue, mesocosm, monitoring, modelling, and conceptual studies, as well as work using eDNA, omics, imaging, and traditional ecological knowledge. Our goal is to build a multidisciplinary perspective on how OA affects biodiversity and how resilience can be supported under global change.

Topics include (but are not limited to):
• OA impacts on species, communities, and ecosystems
• Biodiversity responses to multiple stressors
• Monitoring, observation systems, and long-term datasets
• eDNA, metagenomics, imaging, and emerging tools
• Modelling and predictive approaches
• Resilience, recovery, adaptation, and mitigation strategies

Echinoderms exposed to shifting environmental conditions possess biological mechanisms that allow them to persist. These include intraspecific processes acting at different evolutionary and temporal scales: local genomic adaptations shaped by selective pressures over generations, and phenotypic plasticity expressed as individuals adjust to genotype–environment interactions during their lifetimes. The relationship between echinoderms and their symbiotic microbiota may further influence their adaptive capacity. Our group has adopted a multidisciplinary approach to examine the adaptive potential of key echinoderm species under ocean warming and acidification, combining observations along natural temperature and pH gradients with controlled laboratory experiments. We find diverse stress responses and adaptive strategies—ranging from local genomic differentiation and shifts in gene expression to metabolic adjustments—that vary between species. However, these intra- and interspecific mechanisms do not always align. Differences in evolutionary history and thermal tolerance may underpin the contrasting resilience of echinoderms, offering crucial insights into their survival prospects under future oceanographic change.

Dates: 24 November – 5 December 2025

Location: IAEA Marine Environment Laboratories, Monaco.

Deadline for receipt of application from the nominating national authority: 15 September 2025

Form A and Form C

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).

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 Third 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, with the objective to publish the results in a collective article after the training.

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.

The Biology Working Group of GOA-ON was formed in 2015 with the mission to bridge chemical and biological changes associated with ocean acidification. Over the years, it worked on multiple tasks to (i) inform the chemical monitoring program about the biological needs; (ii) evaluate the needs and requirement of a biological monitoring program; and (iii) develop a theoretical framework linking chemical changes to biological response. Some of this work was recently published (Widdicombe et al. 2023) opening the way to new approaches for chemical and biological monitoring. The working group is now exploring new avenues on current and best practices to evaluate the impact of ocean acidification on biodiversity. This presentation will summarize the activities of the working group and offer to the community (chemists, biologists, modelers) an opportunity to contribute to some of the tasks.

Description: This place-based collaborative effort to understand, anticipate, and prepare for ocean changes affecting natural and human systems owes its success to how oceanographic, ecological, and social scientists and tribal community partners co-designed and co-produced the project. Our goal was to provide an assessment of coupled social-ecological vulnerability to effects from ocean acidification based on new social science and a synthesis of existing data and model projections relevant to the Olympic Coast, its biological resources, and its inhabitants. We outlined eight objectives to guide our project, developing areas of strong integration, including drawing from Indigenous knowledge to inform social science understanding, and drawing on these two systems of knowledge for guiding selection of species of focus for biological risk assessment, with feedback to community preparation and adaptation actions. I will focus on ecological elements of the risk assessment but stress its utility in the context of the social science.

The Environmental Speaker Series is free and open to the public. Talks are held each Thursday at 4:30pm in Academic Instructional Center West, room 204. Join us at WWU or online on Zoom!
