Sail-World.com : Gigantic iceberg sails north from the Antarctic
Gigantic iceberg sails north from the Antarctic


'Satellite image of gigantic iceberg broken from Pine Island Glacier, now drifting north'    .

If you are contemplating ever sailing into the Southern Ocean, there's a new hazard that you might need to look out for. Live Science has reported that, after lingering in its birthing bay for nearly six months, an Antarctic iceberg measuring about 270 square miles in area, or the size of Singapore, is finally heading out to sea.

Strong winds blowing off the continent are pushing the giant floe away from its parent, the giant Pine Island Glacier, and the warming Southern Hemisphere has melted the thick winter sea ice that held the block in place since July, said Grant Bigg, an ocean modeler at the University of Sheffield in the United Kingdom.

The latest satellite images show several kilometers (a couple of miles) of open water between the iceberg and the glacier, Bigg told LiveScience.

'We've been waiting for this to happen,' Bigg said.

The enormous ice block took more than two years to calve (break off) from Pine Island Glacier. A spectacular crack crossing the glacier was first discovered during a NASA IceBridge research flight in October 2011. The iceberg broke free on July 8, 2013, measuring about 278 square miles (720 square kilometers), according to tracking by TerraSAR-X, an Earth-observing satellite operated by the German Space Agency (DLR).

Bigg recently received a grant to track the drifting floe, which could disrupt international shipping lanes.

Icebergs sailing into the ocean from West Antarctica may stay close to the continent's coastline, causing little hazard, or launch out into the Southern Ocean toward the Drake Passage near South America's Cape Horn.

Bigg and his colleagues plan to try to predict the iceberg's path up to a year in advance, based on ocean currents and prevailing winds. The modeling will help the shipping industry improve ice warnings, he said.

Huge icebergs such as the spawn of Pine Island Glacier often shatter into several pieces, and Bigg's team will track and model the fragments if the chunk collapses.

Already, a few small pieces have broken off the west side of the iceberg as it moved in the past few days, Bigg said.

'Each of the last three years has seen a giant iceberg calve, from either Greenland or Antarctica,' he added. 'Being able to track and forecast the tracks of these huge blocks of ice will be a major benefit to the shipping industry, particularly as more ships begin to use polar waters, as Arctic sea ice melts. This ability is what we aim to develop.'

For more information about the iceberg, being watched closely for a couple of years since the original rift was noticed, see this video, created a year ago:
