Pine Island Glacier and Ice Sheet Stability in West Antarctica

In May 2017 CPOM Leeds hosted the concluding meeting of NERC’s Ice Sheet Stability Research Programme (iSTAR), an effort to improve understanding of West Antarctica’s combined Pine Island Glacier–Amundsen Sea system.

Participants reviewed iSTAR’s combined achievements against the programme’s original objectives: understanding the transport of ocean heat toward the ice sheet, understanding the sub-ice processes affecting ice melt, and understanding the response of the inland glacier to the ocean-induced changes.

The main messages coming out of the research were:

  • Future research in this field should include atmospheric processes, not just ice and ocean processes;
  • Long time series observations are critical; and
  • More observations are needed of the floating ice sheet before models can reliably predict Pine Island Glacier’s future behavior.
