Sea surface height maps showing the Haida and Sitka Eddies
The images below show sea surface elevations as measured by
TOPEX/Poseidon
and ERS-2 satellite altimeters. Red regions denote high sea surface and
blue regions denote depressions. Eddies appear as red. The original data
were processed by the Colorado
Center forAstrodynamics Research, and we have added labels to show
the drift of Haida and Sitka eddies between February 1998 and September 2005.
