Responses of the Pan-Arctic Coupled Physical-Chemical-Biological System to ongoing Environmental Changes
Responses of the Pan-Arctic Coupled Physical-Chemical-Biological System to ongoing Environmental Changes
Session ID#: 259460
Session Description:
Rapid ongoing changes to Arctic Ocean environmental conditions challenge our ability to understand the resulting responses and adaptability of the associated coupled physical-chemical-biological systems. Reduced sea ice with accompanying ocean warming, freshening, and changing stratification will modify Pan-Arctic ecosystems and carbon cycling. The Arctic Ocean includes functionally distinct yet connected regions, including inflow, outflow, and interior river-impacted shelves and the deep basin, with different impacts of ongoing change in the heterogenic regions. Recent national and multi-national efforts have organized comprehensive and ambitious assessments of the states and interacting processes of the Arctic basin and adjacent shelf/slope regions that provide valuable benchmarks against which to track status and change in the Arctic Ocean.
We invite presentations that bring together complementary approaches and perspectives, including studies that promote appropriate planning for future multi-national programs and improved coordination of observations. This synergistic approach will improve our understanding of the current temporal and spatial scales while improving documentation of regional, seasonal, and decadal trends and impacts of Arctic change. Further, predictions for future system modifications and their consequences can be enabled, including the potential for development and expansion of commercial fishing.
