BN009:
Evolution of Biogeochemical Cycles in the Arctic Ocean: Predicting the Impact from and on Climate Change.


Session ID#: 27885

Session Description:
The Arctic Ocean shelves, particularly those in the Bering, Chukchi and Beaufort seas, are highly productive ecosystems that host large populations of marine mammals, seabirds and fish. Climate change is dramatically altering primary productivity and water column biogeochemistry as ongoing loss of shore-fast ice and longer ice-free seasons increase light availability, promoting phytoplankton growth. Unknown are impacts from changes in the supply and recycling of essential macro (e.g. N, P. Si) or micro (trace elements, e.g., Co, Fe, Zn) nutrients, which are likely critical for sustaining high productivity in this region. Modifications in carbon cycling and primary productivity may also influence emissions of climatically important traces gases (CO2, CH4, N2O). This session invites contributions investigating biogeochemical cycling of major nutrients and traces elements as well and emissions of greenhouse gases and their impacts on primary productivity and climate in the Arctic Ocean. Presentations based on either field experiments (using for example natural or tracer-level isotopes and molecular microbial ecology techniques), laboratory approaches, or model simulations are welcome.
