Abstract:

Long-term goals of this project are to better understand and quantify the processes that are primarily responsible for redistribution of heat and salt within the Arctic Ocean. The topical focus has been on quantification of the slope-trapped boundary currents and on understanding the roles of small-scale and mesoscale processes in the redistribution of water properties within the central basins. The geographical focus spans the Arctic Basin but emphasizes the Nansen, Amundsen and Makarov basins and the frontal systems that overlie the inter-basin ridges. Four primary objectives contribute to the above goals. Improve the present understanding of mean circulation patterns in the Arctic, with a focus on the topographically controlled boundary currents that redistribute heat and salt. Quantify the speeds, heat, salt and mass transports associated with the boundary currents. Improve our understanding of the nature, distribution and dynamics of upper ocean mesoscale eddies and frontal systems, and assess their role in the transport of heat and salt. Assess the roles of turbulent mixing and double diffusion in redistributing heat and salt, with an emphasis on the impact of these processes on the halocline.
