OC23A:
The Ocean Carbon Cycle Across Timescales I


Session ID#: 37201

Session Description:
Cumulatively since preindustrial times, only the ocean has been a significant sink for anthropogenic carbon. In the coming centuries, the partitioning of carbon between the atmosphere and ocean will determine how further anthropogenic emissions translate into climate change, and at the same time, will determine regional patterns of key biogeochemical stressors, specifically ocean acidification and declines in saturation states of aragonite and calcite minerals. Across the global oceans, the cycling of both natural and anthropogenic carbon varies with climate forcing and biogeochemical drivers. In this session, we welcome contributions that quantify rates and processes of the ocean carbon uptake and its consequences for marine ecosystems, and that address variability and change across timescales from seasonal to millennial. We welcome studies that focus on any open or coastal ocean region, surface or interior, and that use observations, models, and/or theory as the primary approach.
