An iceberg is a large piece of freshwater ice that has broken off a glacier or an ice shelf and is floating freely in open water.[1][2] It may subsequently become frozen into pack ice (one form of sea ice). As it drifts into shallower waters, it may come into contact with the seabed, a process referred to as seabed gouging by ice.
For almost 100 years it carried the blame of sinking the world’s most famous ship, but now, the ill-famed iceberg may be cleared, after some researchers claim they’ve found the true culprit – the Moon. Now don’t get the wrong idea, it was the collision with the ice mass that ultimately brought the demise of [...]
Part of an ambitious NASA survey over the Antarctic, which intends on 3D mapping the continent’s glaciers in detail, one of the project’s planes has sighted a huge, emerging crack on the icy surface. The crack is a 8-mile-long break in an ice shelf, the first sign hinting to the formation of an iceberg that will [...]
On Tuesday, February 22nd, a 6.3 magnitude quake shook New Zeeland, causing severe damage to major cities on the south island, especially Christchurch.Every year, thousands of earthquakes occur in New Zealand that are too small to be felt. However, in the 15 years between 1992 and 2007, New Zealand experienced over 30 earthquakes of magnitude [...]
When you think of Antarctica, pristine white icebergs usually come to mind; probably the last thing you’d expect are humbug-like striped icebergs, with blue, green, yellow and even brown. The different colours appear due to various reasons, but generally speaking they appear because some layers of ice form in special conditions. Blue stripes are the [...]
