HE43A:
Biophysical Processes at the Arctic–Sub-Arctic Interface II


Session ID#: 11353

Session Description:
The Arctic is changing at a rapid pace with potentially dramatic consequences for the marine ecosystems of the North. This session aims to explore patterns and processes at the interface between Subarctic and Arctic waters of the Pacific Arctic, the gradients in physical characteristics and biological communities that shape this region, and the role of climate change in modifying biophysical processes in the region. What happens in the (Sub-) Arctic does not stay in the (Sub-)Arctic due to strong meridional connections between Subarctic and Arctic waters, including substantial inflows into the Arctic through Bering Strait and large seasonal migrations of seabirds and marine mammals.  These connections imply substantial exchanges of physical and biological material across the Arctic-Subarctic interface that modify biological productivity in both regions, determine the distribution of biota at all trophic levels, and affect the availability of prey to upper trophic levels, including humans. As interest in the Arctic has grown, so has the number of research programs with a focus on Arctic marine ecosystems. We encourage submissions that draw on recent integrated research programs to examine processes at the Arctic-Subarctic interface at all levels from plankton to marine mammals and humans.
