HE14B:
New Insights into the Beaufort Gyre of the Arctic Ocean: Scientific Questions, Observing Technologies, and Modeling Capabilities I Posters

Session ID#: 84248

Session Description:
One of the foci of the Forum for Arctic Modeling and Observing Synthesis (FAMOS) project is improving Arctic regional ice-ocean models and understanding of physical processes regulating variability of Arctic environmental conditions based on synthesis of observations and model results. The Beaufort Gyre centered in the Canada Basin of the Arctic Ocean is an ideal phenomenon and natural laboratory for application of modeling capabilities to resolve numerous scientific questions related to the origin and variability of this climatological flywheel and freshwater reservoir of the Arctic Ocean. The unprecedented volume of data collected in this region enables us to describe the state and changes in this environmental system at synoptic, seasonal and interannual time scales. The in situ and remote sensing data characterizing oceanic hydrography, sea surface heights, ice drift, concentration and thickness, ocean circulation, and biogeochemistry are publicly available for comparison with models or assimilation for historic reconstructions and establishing initial conditions for prediction systems. This session invites multidisciplinary contributions from observers, theoreticians, numerical modelers and engineers to present and discuss new methodologies in observing, modeling and analysis and to shed light on the mechanisms regulating the Beaufort Gyre dynamics as it transitions to a new state under different climate forcing.
