The first sighting of an all-white male orca (YouTube 1, 2) is reported by Eric Hoyt, Senior Fellow with the Whale and Dolphin Conservation Society, UK.
Three thousand years ago, snow fell on Greenland, creating what would become an iceberg in this century. Centuries pass and snow piles up, until it is 60 to 70 meters thick and forms glacial ice. As glaciers slowly flow into the ocean, the end of the glaciers calve, or break off. In Greenland, some 40,000 medium to large sized icebergs calve each year, making their way south. Of the 10,000 to 15,000 icebergs annually calved from glaciers in the Arctic, on the average only 375 pass Newfoundland into the North Atlantic Ocean. On April 14, 1912, an iceberg was some 5,000 miles south of the Arctic Circle when a boat ran into it, leaving a smear of red paint along the base of the berg. [more inside]
On August 5, 2010 in the north-east corner of Greenland, about 100 square miles (251 square kilometers) of the Petermann Glacier broke off (or calved, see: glacial geology terminology), and in time for the 35th anniversary for the coining of the term "Global Warming". The glacier has been showing signs of breaking up in the last few years, but this is the most dramatic loss for the Petermann Glacier in ten years, yet still far from being the largest calving event in recorded history.

I didn't know until this morning that icebergs could be striped. However, apparently that's just one of many variations. Here's where to find some and learn more. [More beneath the surface.]
As predicted and previously discussed, the world's largest collision took place in Antarctica when a 115km (71mile) long iceberg collided with the Drygalski ice tongue in McMurdo Sound. The resulting satellite photographs show the results of the collision quite clearly, but somehow fail to convey the sheer scale of the event.
