The National Ice Center reports that another new iceberg has broken away from Antarctica. An iceberg the size of St. Lucia Island in the Caribbean Sea broke off from the Lazarev Ice Shelf, a large sheet of glacial ice and snow extending from the Antarctic mainland into the southeastern Weddell Sea.
The new iceberg, D-17, is 34.5 miles long and 6.9 miles wide. It was observed on an image collected by the Defense Meteorological Satellite Program. Icebergs are named for the area quadrant of Antarctica where they appear. D-17 is the 17th berg reported since record keeping began in 1976.
