"Changing Coastal-Ocean Biogeochemistry Along The Western Antarctic Peninsula" with Scott Doney, Woods Hole Oceanographic Institution (WHOI).

The Antarctic continental shelf and surrounding open-ocean waters of Southern Ocean play important roles in marine biogeochemistry and the global carbon cycle. Seasonally ice-covered coastal waters are often highly productive, exhibiting large spring and summer drawdowns of nutrients and carbon dioxide and supporting high densities of upper trophic level organisms. Off-shore waters are typically more iron limited with lower plankton standing stock and overall productivity. Climate change and ocean acidification are projected to alter substantially future sea-ice distributions, seawater chemistry, and ocean/atmosphere circulation patterns that modulate regional marine biogeochemistry. The talk will discuss observational, remote sensing and modeling evidence for changing conditions in the Southern Ocean. A specific focus will be on the western continental shelf of the Antarctic Peninsula, which is experiencing some of the most dramatic climate change on the planet, with rapid ocean-atmosphere warming, melting of coastal glaciers, reductions in seasonal ice cover, and shifts in phytoplankton distributions.
