Whilst completing my M.Phil at SPRI I developed a new automated system for tracking Greenland tidewater glacier frontal positions using MODIS (satellite) data. By reducing the amount of researcher labour required to gather glacier positions, the method allowed data to be collected from 105,536 glacier images, giving a detailed account of East Greenland glacier retreat and other behaviour during the rapid speed-up events of the past decade. Large scale retreat was found on southern glaciers, with little change further north. Widespread seasonal patterns were also found to 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 their research.
