Description:	The Consortium, Estimating the Circulation and Climate of the Ocean (ECCO) is directed toward estimating the time-evolving state of the global ocean by synthesizing diverse observational data with general circulation models. A long-term goal is to provide a high-resolution, physically consistent coupled ocean/sea-ice/biochemical (and ultimately, atmospheric) state estimate to a wide community for a large number of purposes ranging from climate change and forecasting, biogeochemical cycles, coastal applications, to Earth rotation. In working towards its long-term goal, ECCO has spun off several projects, including ECCO-GODAE, the G(erman)-ECCO five-decade synthesis, and ECCO-2 whose goal is estimation at eddy-permitting resolution. The products and tools from these projects have been supporting research and applications under the Climate Variability and Predictability (CLIVAR) program and the Global Ocean Data Assimilation Experiment (GODAE). This session will provide an opportunity for ECCO product users to (a) describe the scientific implications of their results, (b) enhance the feedback from the broader community to the Consortium, (c) foster the interaction between ECCO members and other scientists who utilize the state estimates. Presentations describing recent scientific applications of ECCO products and tools are particularly solicited, including general circulation, climate change, biogeochemistry, coastal processes, geodesy, hydrology, as are descriptions of forthcoming enhancements of the ECCO models and data.
