Antarctic Ocean Flows: an excerpt from Atlas of a Changing Earth (Dome Master format)

As we approach the Pine Island Glacier, we dip below the surface of the bay and see the stratification of the temperature in the ocean flows, with the coldest water shown in blue near the surface and the warmer water shown in red at lower depths. We move forward under the floating ice of the Pine Island Glacier and see how the warmer ocean flows are circulating under the glacier's floating tongue, eroding the ice from beneath.
The topography in this visualization has been exaggerated by 4x above sea level and 15x below sea level in order to more clearly observe the change in ocean temperature at various depths.
This version is provided in Dome Master format meant for projection onto a planetarium dome. A version of this visualization designed to play on a flat screen is available here.
