HE13A:
Carbon Cycling in Arctic Ocean and Adjacent Marginal Seas Under a Changing Climate I


Session ID#: 37004

Session Description:
The Arctic Ocean and adjacent Arctic and Subarctic marginal seas disproportionately affect and are affected by climate change, rising atmospheric CO2, and the evolving ocean carbon cycle, the result of dramatic changes in sea-ice cover, high CO2 solubility in colder and fresher waters, and dynamic biological activity influenced by changing circulation and transfers of nutrients and carbon between interior water masses and terrestrial reservoirs. Contributions are solicited examining carbon cycling within the Arctic Ocean and adjacent Arctic and subarctic marginal seas, and carbon-transfers between these waters and the atmosphere, seafloor, adjacent continents, and bordering oceans. A number of recent and emerging studies have added to the study of carbon cycle observations and relevant processes, and their syntheses, in these sensitive environments. Both observational and modeling studies are encouraged to apply.
