Relevant OA research for science and society (text & video)

OA Week 2021, Northeast Atlantic Hub

Dr. Richard Bellerby, Norwegian Institute for Water Research, Norway


An understanding of the present state, variability and projections of coastal OA is necessary to facilitate appropriate management and investment strategies. This is in line with the Sustainable Development Goal 14: Conserve and sustainably use the oceans, seas and marine resources for sustainable development. One target for this goal is 14.3 stipulating the need to minimise and address the impacts of ocean acidification, including through enhanced scientific cooperation at all levels. Despite the challenges to ecosystems and ecosystem services expected from OA, measures to adapt to OA are still hard to come by. While OA is mentioned as an issue in regional management plans and in white- and green papers, for instance regional climate plans in Norway, there are few examples of concrete measures. This presentation reports on a study of OA in coastal Norway where stakeholders had critical roles in scientific design, sampling and data interpretation. The study confirmed that ocean acidification thresholds are already experienced in Norwegian coastal systems and will be a growing challenge. The projected timing for when critical thresholds will be crossed is locally site, depth and service dependent. The project´s co-design and the co-production of new knowledge on coastal OA were essential to deliver targeted, relevant and comprehensible scientific products for coastal users, regulators and industry.

Ocean Acidification Week 2021 was sponsored by the following organizations:

(1) GOA-ON, the Global Ocean Acidification Observing Network,

(2) NOAA, the United States National Oceanic & Atmospheric Administration,

(3) IAEA OA-ICC, the International Atomic Energy Agency – Ocean Acidification International Coordination Centre, and

(4) IOC-UNESCO – the Intergovernmental Oceanographic Commission of the United Nations Educational, Scientific and Cultural Organization
