Petermann Ice Island-A off Newfoundland
This page contains archived content and is no longer being updated. At the time of publication, it represented the best available science. However, more recent observations and studies may have rendered some content obsolete.
The Petermann Ice Island-A (PII-A) was about 16 kilometers (10 miles) off the Newfoundland coast on August 4, 2011. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite took this picture the same day.
The ice island floats in the ocean under a corridor of clear sky between two cloudbanks. The northeastern tip of Newfoundland and Belle Isle also appear, but clouds hide Labrador. White dots southwest of the ice island could be small clouds, but may also be ice chunks recently calved off PII-A. In July 2011, the Canadian Ice Service reported that PII-A was losing mass through melting and calving.
PII-A is a remnant of a much larger ice island that calved off the Petermann Glacier in northwestern Greenland almost exactly one year before MODIS acquired this image. The ice island broke free from the glacier on August 5, 2010. That ice island was roughly 97 square miles (251 square kilometers).
As of July 27, 2011, PII-A had a surface area of about 50 square kilometers (19 square miles), according to the Canadian Ice Service. Another remnant of the original ice island, PII-B-a, had a surface area of about 21 square kilometers (8 square miles) and was located in Lancaster Sound.
