Biophysical Interactions at the Poles: from the Coasts to the Open Ocean

Session ID#: 259371

Session Description:
Polar oceans host some of the most dynamic ecosystems on the planet. Complex physical and biogeochemical processes contribute to the polar oceans’ outsized influence on global biogeochemical cycles and impose strong regional variability across various spatio-temporal scales and trophic levels. In particular, cryospheric interactions are incredibly dynamic due to variability in polynyas, tidewater glacial fjords, and the marginal ice zone, as well as ongoing changes in sea ice and ice shelves. Characterizing the mechanisms of biophysical coupling is critical to i) understanding ecosystem dynamics and their downstream impacts and ii) assessing the ongoing and intensifying change in the Arctic and Southern oceans and their associated coastal waters.

Advances in autonomous observing technology and computational methods allow us to broaden our understanding of polar biophysical interactions. This session seeks to bring together observationalists and modelers investigating variability in biogeochemical cycling as well as heterogeneity in plankton biomass or higher trophic levels in the open or coastal polar oceans. We welcome studies that consider any range of scales from the turbulent to the basin-scale at daily to interannual timescales, as well as work examining the interactions between scales. The session particularly welcomes interdisciplinary presentations that synthesize biological, ecological, and physical approaches.
