In the Antarctic, researchers made a detailed survey of the Pine Island, Thwaites, Smith, Kohler and Crane glaciers, while another instrument peeked at the detailed topography under Pine Island's floating ice tongue.
Located at about 67[degrees]N latitude, Helheim had been retreating rapidly since 2003 and had lost most of its ice tongue.
Small rocky islands near the mouth of the fjord hem in the ice tongue and may impede the flow and rapid loss of glacier ice into the fjord.
If the researchers could find a way to measure the temperature of waters underneath the ice tongue, 79N offered a fine natural laboratory for observing the effects of warming seawater on a glacier/fjord system that was not accelerating.
Scientists say the shearing off of the ice tongue and the presence of the Mertz and B-9B icebergs could affect global ocean circulation.
Nasa satellites have spotted the B- 15 A iceberg moving toward the Drygalski Ice Tongue and scientists expect a collision to occur no later than Saturday: ``It's a clash of the titans, '' said Robert Bindshadler, a Nasa research scientist.
He said that when the iceberg and the ice tongue collided, the impact would likely ``dent their bumpers''.
According to a report in New Scientist, a group of scientists and climate change activists who are closely monitoring the Petermann glacier's ice tongue believe that the rapid flow of ice is in part due to warm ocean currents moving up along the coast of Greenland, fuelled by global warming.
During the summer of last year, Jason Box of Ohio State University in Columbus noticed a huge crack in the glacier's floating ice tongue, which acts as a conveyor belt, pushing the glacier's ice through a fjord and out to sea.
The three sites all sit offshore from ice shelves or smaller ice tongues, aprons of glacial ice that extend into the ocean.
AT first sight, it is surprising to learn that the mesmerising wall-mounted display of dripping, flesh-coloured ice tongues which encase a series of knives is part of the same exhibition as a vast diorama of toy figures scattered around a floor map of Asia and the Far East.
