Plenary 5: detection, attribution, & predictability of ocean acidification (text & video)

OA Week 2021, Plenary Session 5 Attribution & Blue Carbon

Dr. Scott Doney, Joe D. and Helen J. Kington Professor in Environmental Change, University of Virginia, USA


Uptake of anthropogenic carbon dioxide from the atmosphere by the surface ocean is leading to global ocean acidification, but regional variations in ocean circulation and mixing can dampen or accelerate apparent acidification rates. Excess nutrient pollution can also result in coastal acidification in estuaries and near shore regions. Both climate variability and nutrient pollution exacerbate the ecological press from rising atmosphere CO2 and can cause extreme acidification events that are detrimental to ecosystem health and fisheries.

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
