. The Rungholt iceberg, which was detached from Greenland’s Helheim Glacier in 2020, is currently drifting in the North Atlantic Ocean. Measuring over 4,400 square kilometers, or 1,700 square miles, it is the largest on record to break away from a glacier. The giant iceberg is currently heading northwest towards Iceland, and is estimated to be between 500 and 1,100 feet thick. Scientists are monitoring the iceberg’s movements in order to protect nearby shipping lanes, oil and gas rigs, and fishing activities. It is expected to break up and melt over time.
