Deep-ocean steric sea level variations in the Northwest Atlantic Basin revealed using Deep Argo and Bermuda Atlantic Time-series Study full-depth profiles Nathalie Zilberman(1), William Llovel(2), Jacob Steinberg(3), and Antoine Hochet(2) (1) Scripps Institution of Oceanography, UCSD, California (2) LOPS/CNRS, Brest, France (3) NOAA GFDL, Princeton, New Jersey The global mean sea level budget closes between 2005 and 2015 when using a decadal trend in deep-ocean steric change based on historical data but that is no longer the case between 2005 and 2019. While some of the non-closure of the global sea level budget can be explained by limitations of conductivity temperature depth sensors on Argo floats, satellite altimeters, and GRACE/GRACE-FO accelerometers, the lack of homogeneous observations in the deep ocean at regional-to-global and subseasonal-to-interannual scales is thought to play a significant role. Work will be presented that makes use of full-depth ocean temperature and salinity profiles collected ...
