The role of Pine Island Glacier ice shelf basal channels in deep-water upwelling, polynyas and ocean circulation in Pine Island Bay, Antarctica

The role of Pine Island Glacier ice shelf basal channels in deep-water upwelling, polynyas and ocean circulation in Pine Island Bay, Antarctica

Several hundred visible and thermal infrared satellite images of Antarctica’s southeast Amundsen Sea from 1986 to 2011, combined with aerial observations in 2009, show a strong inverse relation between prominent curvilinear surface depressions and the underlying basal morphology of the outer Pine Island Glacier ice shelf. Shipboard measurements near the calving front reveal positive temperature, salinity and current anomalies indicative of melt-laden, deep-water outflows near and above the larger channel termini. These buoyant plumes rise to the surface and are expressed as small polynyas in the sea ice and thermal signatures in the open water. The warm upwellings also trace the cyclonic surface circulation in Pine Island Bay. The satellite coverage suggests changing modes of ocean/ ice interactions, dominated by leads along the ice shelf through 1999, fast ice and polynyas from 2000 to 2007, and larger areas of open water since 2008.

Pine Island Glacier and Pine Island Bay

Pine Island Glacier and Pine Island Bay

Pine Island Bay in the southeast Amundsen Sea, Antarctica, on 16 Nov 2008. Upwelling, melt-laden outflow plumes emerge from beneath the adjacent Pine Island Glacier ice shelf (top center) and mix in the bay waters. Warm red colors show sea surface temperatures more than a degree warmer than the near-freezing dark blue color. Cyclonic circulation in the bay is framed by the ice shelf, land ice and sea ice, in gray-scale with the darker shades colder. Landsat Enhanced Thematic Mapper Plus image, thermal infrared (channel 6H), subset of scene #LE72331132008321EDC00.

Kinects as sensors in earth science: glaciological, geomorphological, and hydrological applications

Last week I presented a poster at the 2011 AGU Fall Meeting. It has generated some press thanks to an article in Wired. If you are interested in the poster it is available by clicking on the image below.

ANDRILL in Google Earth

I’ve released my Google Earth layer. Your comments and suggestions and data are welcome.

The KML (download here) is a very small network access file. Load it once, save it in the Google Earth sidebar, and all updates will be available each time you launch Google Earth. You need the latest Google Earth to view this layer.

This was presented at the SCAR IASC conference in St. Petersburg, Russia, July 8-11, 2008.
