Monthly mean Dynamic Ocean Topography (DOT) and geostrophic currents over the Canada Basin, from 2003 to 2014

The animation shows the monthly mean Dynamic Ocean Topography (DOT) and geostrophic currents (black vectors) over the Canada Basin (broadly defined as the Beaufort Gyre region), from 2003 to 2014. The red line indicates the maximum closed contour of the DOT (within this region) and the red cross ind...

Description
Summary:The animation shows the monthly mean Dynamic Ocean Topography (DOT) and geostrophic currents (black vectors) over the Canada Basin (broadly defined as the Beaufort Gyre region), from 2003 to 2014. The red line indicates the maximum closed contour of the DOT (within this region) and the red cross indicates the DOT centroid. The DOT is calculated as the difference between the satellite altimetry estimates of sea surface height (from Envisat: 2003-2011 and CryoSat-2: 2012-2014) and the geoid. Geostrophic currents are calculated from spatial gradients in the DOT.
