Sea Level Variation at the North Atlantic Ocean from Altimetry
Abstract
About twenty years of multi-satellite radar altimeter data are analyzed to investigate the sea-level variation (SLV) of the North Atlantic Ocean. In particular seasonal variations and inter-seasonal trends are studied. Sea surface temperature and ice mass lost variations at Greenland are investigated as potential contributors of SLV in the case. It was found a quadratic acceleration term to be significant at some areas mainly located at the sub-polar gyre region. Results are consistent with changes in temperature data.
