OC41A:
Changing Ocean Biogeochemistry in a High CO2 World: Observations Across Time and Space II


Session ID#: 37127

Session Description:
As a major CO2 sink, the ocean plays a critical role in curbing the rise of atmospheric CO2. However, ocean uptake of anthropogenic CO2 since the Industrial Revolution has decreased seawater pH and calcium carbonate saturation states at an unprecedented rate, a process known as ocean acidification (OA). OA has been documented by direct observations over the last few decades at various locations, and is causing complex biogeochemical changes over a range of temporal and spatial scales. This session will highlight new research findings on OA-driven changes in ocean biogeochemistry, including links to other ocean changes (e.g., deoxygenation). We invite contributions spanning diverse time scales, ranging from contemporary observations that document the current status of OA and its biogeochemical impacts, to paleo-studies that investigate OA impacts over a broader geological context. We welcome studies of OA impacts from open-ocean to coastal systems, where many complex processes make OA difficult to study and predict. We also encourage submissions that highlight emerging observational technologies and methods that advance the frontiers of OA research. This session will help to review ‘the state of the science’ and identify major unknowns in this field. This activity is sponsored by the Ocean Carbon & Biogeochemistry Program.
