Location and Topography of New Sub-Glacial Basin in West Antarctica (image) University of Texas at Austin Share Print E-Mail Caption The bottom image shows a radar image of bedrock elevation reveals the new sub-glacial basin (purple and blue regions). The basin is divided into two components (A and B) and lies just inland of the West Antarctic Ice Sheet's grounding line (black line), where streams of ice flowing toward the Weddell Sea begin to float. The top image shows a white box indicating the location of the bottom image. Pine Island Glacier and Thwaites Glacier -- two parts of the West Antarctic Ice Sheet previously studied by the US and UK researchers -- drain into the Amundsen Sea.
