DESCRIPTION:Pine Island Glacier (PIG) has been losing mass since at least 
 the start of the satellite observational record in the 1970s. In recent de
 cades it has undergone periods of rapid grounding line retreat\, accelerat
 ion and inland thinning\, prompting fears about the glacier being in an un
 stable configuration. Mass loss from this region is caused by enhanced oce
 an-induced basal melting\, which can lead to a reduction in ice shelf butt
 ressing and increased ice flow. Here\, I present the initial results of a 
 study which uses a vertically-integrated ice flow model and 1D plume model
  to study a recent period of rapid PIG retreat. I investigate the conditio
 ns that may have led to PIG ungrounding from a submarine ridge and migrati
 ng back to it's current day position.
