Animation of circulation around ice shelves of Antarctica.
This animation shows the circulation of ocean currents around the western Antarctic ice shelves. The shelves are indicated by the rainbow color; red is thicker (>550m), while blue is thinner (<200m). The ocean flow runs from the surface to 900 m, colored white at the surface and fading to light blue at depth, and is based on the ECCO2 model over a representative two-month period. Bathymetry, topography, and ice thickness were derived from the RTopo-1 dataset of Timmermann, et al. (http://doi.pangaea.de/10.1594/PANGAEA.741917). Ground color is from MODIS/Blue Marble.
