Abstract:

The changes of ice shelves and glaciers are major processes for dynamic changes in Antarctica. MODIS L1B 250 m resolution data and Landsat 15 m resolution panchromatic data are used to investigate dynamic changes in the Amery Ice Shelf, Polar Times Glacier, Polar Record Glacier and Dalk Glacier from 2000 to 2016. The changes in area and annual rate of change are analyzed. The results show that the Amery Ice Shelf has grown in extent over the past 16 years and that its front has advanced at a steady rate. The Polar Times Glacier and Polar Record Glacier continued to advance during those years, and an iceberg calved from the Polar Times Glacier in 2007. The area of icebergs in front of the Polar Record Glacier has decreased annually since a calving event in 2014. The Dalk Glacier has alternated between advancing and calving.
