Substantial changes in the coastline of Antarctica revealed by satellite imagery

ABSTRACT Noaa Avhrr and Landsat MSS imagery acquired between January and November 1986 has shown substantial changes in the Antarctic coastline near the Filchner Ice Shelf, Larsen Ice Shelf and Thwaites Glacier. In the Filchner Ice Shelf area some 11,500 km of ice calved from mid-April onward. In th...

Description
Summary:ABSTRACT Noaa Avhrr and Landsat MSS imagery acquired between January and November 1986 has shown substantial changes in the Antarctic coastline near the Filchner Ice Shelf, Larsen Ice Shelf and Thwaites Glacier. In the Filchner Ice Shelf area some 11,500 km of ice calved from mid-April onward. In the Larsen Ice Shelf area two large bergs calved between February and August. The combined volume of ice from these two events equals approximately three years' normal calving from the entire Antarctic coastline. In the Thwaites Glacier area several changes appear to have occurred at the base of Thwaites Iceberg Tongue and Thwaites Glacier Tongue.
