Whale fluke near icebergs at Jacobshavn Isfjord

Whale fluke near icebergs at Jacobshavn Isfjord, summer in Greenland. When chunks of glaciers break off, or calve, icebergs are born. Icebergs may also break off from ice shelves or a larger icebergs. Sometimes the violent birth of an iceberg can cause a huge wave. Other times, as an iceberg melts, it might flip completely over where the underside is larger than what previously appeared above the sea. This is but one reason boats are warned not to be too close and allow their curiosity to potentially endanger them. Photo by Julie Skotte via Visit Greenland
