This animation shows the ocean currents colored by their velocity circulating around and under the Pine Island ice shelf. Orange and yellow indicate faster currents while green and blue depict slower. A small red marker indicates the location of the drill site. In this animation, the Pine Island ice shelf is temporarily sliced away to reveal the ocean flows under the ice and subsequently restored up to the location of the drill site. A shaft penetrates through the ice sheet and the instrument is lowered through the shaft into the water that flows beneath the ice shelf.
In this animation, the topography and ice shelf thickness is exaggerated by 15 times.

Missions
This visualization is related to the following missions:Datasets used in this visualization
ECCO3 High Resolution Ocean and Sea Ice Model
Landsat-7 LIMA (A.K.A. Landsat Image Mosaic of Antarctica) (Collected with the ETM+ sensor)
Mosaicing to avoid clouds produced a high quality, nearly cloud-free benchmark data set of Antarctica for the International Polar Year from images collected primarily during 1999-2003.
