October marks the beginning of summer in Antarctica—that time of year
when the sun shines all day, every day and the temperature begin to
rise. The long hours of sunshine from October until March allow
excellent satellite views of the icy terrain which lays hidden during
the winter (March through September). The Moderate Resolution Imaging
Spectroradiometer (MODIS) on board NASA’s Terra satellite captured a
true-color image of East Antarctica’s Amery Ice Shelf on October 22,
2021.

Although the Amery Ice Shelf makes up only a small portion of the
Antarctic coastline—a swath about the size of the state of West
Virginia—this ice shelf drains about 16 percent of the East Antarctic
Ice Sheet. Like other ice shelves, the Amery deposits ice into the
ocean through the natural cyclical process of iceberg calving. This
process can be extremely slow, sometime taking decades to complete. The
last iceberg broke from the Amery Ice Shelf in 2019.
