HE31A:
Changing Biogeochemical Fluxes, Biodiversity, and Ecological Processes in the Polar Seas, with Special Emphasis on the Coastal Arctic and Sustaining an Integrated Arctic Ocean Observing System II

Session ID#: 92317

Session Description:
Inextricably linked to climate change, the Polar Seas are undergoing drastic changes with global implications. Arctic and Antarctic sea ice and ice sheets are melting, the ocean is acidifying, freshwater fluxes and mixing regimes are changing. Yet, the impacts on marine biodiversity, biogeochemistry, and the function of polar communities and ecosystems remain poorly characterized. These factors, among others, will influence the design, implementation, and enhancement of sustained and integrated polar ocean observing systems urgently needed to assess current conditions and enable improved predictions. This session will bring together modelers, observationalists, and other stakeholders to exchange information and improve understanding on the current state-of-knowledge, gaps, and challenges in observing and modelling the coupled physical, biogeochemical, and ecological processes in the rapidly changing polar oceans, with an emphasis on the coastal Arctic. Submissions are also encouraged on multipurpose observing technology and platforms that form an integrated shared infrastructure for use in the Arctic Ocean (e.g., acoustics and cabled systems). We seek interdisciplinary data and synthesis products that relate climate change to biodiversity changes, altered biogeochemical cycles, and ecological shifts across spatial scales, how feedbacks and controls operate and, ultimately, what new conditions might be present in Earth’s polar systems on decadal and longer time scales.
