SUMMARY:Automatic satellite monitoring of East Greenland's calving glacier
  fronts: seasonal signals and southern retreat - Anthony Seale (University
  of Cambridge)

DESCRIPTION:Whilst completing my M.Phil at SPRI I developed a new automate
 d system for tracking Greenland tidewater glacier frontal positions using 
 MODIS (satellite) data. By reducing the amount of researcher labour requir
 ed to gather glacier positions\, the method allowed data to be collected f
 rom 105\,536 glacier images\, giving a detailed account of East Greenland 
 glacier retreat and other behaviour during the rapid speed-up events of th
 e past decade. Large scale retreat was found on southern glaciers\, with l
 ittle change further north. Widespread seasonal patterns were also found t
 o exist on many glaciers. The role of the ocean in controlling retreat is 
 considered\, attempting to explain the observations. This talk will be of 
 interest to remote sensors\, glaciologists and M.Phil students beginning t
 heir research.
