Abstract
The “Estimating the Circulation and Climate of the Ocean” (ECCO) Consortium has a 20-year legacy of supporting fundamental climate research through the sustained production of innovative, global multi-decadal geophysical ocean state estimates. ECCO estimates are free-running solutions to state-of-the-art numerical general circulation models that are constrained with diverse, heterogenous, and sparse satellite and in-situ measurements in a least-squares sense. In recent years the ECCO project has sought to better represent the drivers of global and regional sea level rise, including the contributions from ocean-driven melting of the Greenland and Antarctic Ice Sheets. This talk describes some of the challenges and benefits of expanding the scope of ECCO's original "ocean-only" state estimation system to include useful representations of ocean/cryosphere interaction in general and ocean/ice-sheet interaction in particular.
