Sea level trend (mm/year) in the Atlantic Ocean for January 1993 to June 2014

Map of regional patterns of observed sea level (in mm/year). This map can be obtained using gridded, multi-mission Ssalto/Duacs data since 1993, which enable the local slopes to be estimated with a very high resolution (1/3 of a degree on a Mercator projection). Isolated variations in MSL are thus revealed, mainly in the major ocean currents. see www.aviso.altimetry.fr/msl
