Greenland Glacier Break Creates New Ice Island the Size of Manhattan
A massive iceberg has broken off from the Northern Hemisphere’s longest floating ice tongue, and researchers are anticipating at least two more calving events from Greenland’s Petermann Glacier in the near future. The recent calving event marks the glacier’s largest loss of floating ice since 2012 and offers scientists a rare opportunity to study how large ice masses form and drift apart over time. Break away Scientists have been using satellites to monitor changes in Petermann Glacier since 2019, keeping a close watch on fractures and signs of instability along the glacier’s floating ice tongue.

Opening excerpt (first ~120 words) tap to expand
A massive iceberg has broken off from the Northern Hemisphere’s longest floating ice tongue, and researchers are anticipating at least two more calving events from Greenland’s Petermann Glacier in the near future. Satellite imagery from the European Space Agency’s Sentinel-1 mission first revealed deterioration in Petermann Glacier’s ice tongue—a floating sheet of ice that extends 43 miles (70 kilometers) out into the Arctic Ocean—on August 3 before the ice island completely detached from the eastern side of the glacier the next…
