Changes in morphology at the margin of the Greenland ice sheet (Leverett Glacier), in the period 1943-1992: a quantitative analysis

Description :
Changes in ice-marginal morphology near Leverett glacier, a small outlet glacier at the of the Greenland ice sheet, are determined from a photogrammetrical analysis. To be able to compare two datasets from subsequent years with measurements at different coordinates, kriging was used for interpolation. In this study the kriging standard error is used to evaluate the relative accuracy of the resulting maps. Aerial photographs of 1943, 1968 and 1985 were compared. Especially, the amount and rate of erosion and deposition within glacial systems during a period of glacier retreat (1943-1968) and of advance (1968-1992) are evaluated.
