|a We investigate the regional-ocean depth layer (down to 2000m) contributions to global mean
steric sea level from January 2004 to March 2010, using Argo-based ocean temperature and
salinity data from the SCRIPPS Oceanographic Institution database. We find that Indian
ocean warming is almost compensated by Atlantic ocean cooling, so that the total global mean
steric sea level increases only slightly over the considered period (0.35 +/- 0.30 mm/yr). A
decrease in salinity in the latter ocean also contributes to the observed steric compensation.
Meanwhile, the Pacific steric sea level increases only slightly (0.35 +/- 0.25 mm/yr). In the
North Atlantic region (and principally in the tropical Atlantic between 0° and 20°N), the mean
sea level and ocean mass component (estimated by the difference between satellite altimetrybased
minus steric sea level over the same area) shows strong interannual variability
significantly correlated with the ENSO., with positive sea level and ocean mass anomalies
corresponding to ENSO cold phases (La Nina). This result placed in the context of a previous
study on ENSO-driven land water contribution to sea level interannual variability suggests
some link between tropical Pacific state, water cycle and tropical Atlantic sea level and ocean
mass during ENSO events. |
