Amundsen admitted that he was heavily in debt and knew that his best chance of raising money was to bring off a spectacular triumph.
Amundsen's excuse to the others was that Hanssen was suffering too severely from frostbite to linger behind...the men were not totally convinced.
Amundsen's decision was not a revengeful one as he felt that if the Pole party were not successful, at least there might still be a "first" gained for Norway.

In a paper published today in the online edition of the journal Science, one team said the vast glaciers flowing into the Amundsen Sea were thinning twice as fast near the coast as they had in the 1990's.
Amundsen Sea glaciers contain enough ice to raise sea level by 1.3 meters (4 feet)," the researchers wrote in their report.
The melting into the Amundsen sea is now more than the previous amount from all of Antarctica and more than the estimated contribution from Greenland, the researchers said.

A sea (pronounced see) is a large expanse of saline water connected with an ocean.
The term is also used for large, usually saline, lakes that lack a natural outlet, such as the Caspian Sea and the Sea of Galilee.
The term is used in a less geographically precise manner as synonymous with ocean, as in the tropical sea or down to the sea shore, or even sea water referring to water of the ocean.

  Around 700,000 km3, or ~1.1 m eustatic sea level rise of ice is frozen within the AS sector, and this is drained principally through the PIG, TG, SG systems (75, 77 and ~7 km3 yr-1 respectively from 5,6,7).

Sea ice drift in the Amundsen Sea and its forcing and variability is analysed using data from three buoys deployed on the ice in March 2000 and results of the coupled ice-ocean model BRIOS (Bremerhaven Ice Ocean Simulations).
A first sea ice budget is presented for the Amundsen Sea with meridional and zonal transports of almost equal magnitude and weak import from the Bellingshausen Sea.
Transport magnitude and variability at the western boundary towards the Ross Sea depend strongly on the interplay between zonal easterlies and westerlies and meridional winds, which leads to accumulation of sea ice in or export from the southern Amundsen Sea.

 Comparison of ERS-SAR Backscattering Coefficients with In Situ Measurements of the ...
Present numerical sea ice models predict among others the ice drift and some characteristics of deformation, which may be related to the ice roughness.
The SAR backscatter coefficients are correlated with these data, acquired in the Bellingshausen and Amundsen Seas in February 1994 during an expedition of RV Polarstern.
In a first step two significantly different sea-ice regimes are identified: The ice in the central Bellingshausen Sea was moderately deformed with mean thicknesses of 1 to 1.2 m, while the mean ice thickness in the Amundsen Sea ranged from 2 to 3 m.

The Ross Sea and Weddell Sea embayments have been the primary focus of attention within the West Antarctic Ice Sheet (WAIS) since the potential for ice sheet collapse and its resulting impact on sea level was first recognized.
The Amundsen Sea Embayment (ASE), on the other hand, has been comparatively unstudied primarily due to its remoteness from logistical centers.
Recent satellite remote sensing studies, combined with limited ice thickness data, indicate that the ASE discharges the largest ice flux in West Antarctica; furthermore, of all the major drainage basins in Antarctica, it is the only one to exhibit significant elevation change over the period of these satellite observations.

As its fringes collapse, the ice of Antarctica is slipping into the sea.
It is particularly vulnerable because it rests on land that lies below sea level, and there is a danger that if the ice shelves surrounding it were to disintegrate, the entire ice sheet could slide into the sea.
The melting ice shelf does not in itself affect sea level, because floating ice displaces its equivalent volume of water.

 Radar developed by KU researchers detects more rapidly thinning glaciers
LAWRENCE -- Glaciers in western Antarctica seem to be thinning more rapidly than in the 1990s, and the resulting flow of ice into the Amundsen Sea contributes to a faster rise in the world's sea levels, according to the scientists from the University of Kansas, NASA and Chile's Center for Scientific Studies.
About 253 cubic kilometers of ice are moving from the glaciers into the Amundsen Sea each year, the researchers say -- a volume equal to about 241,000 Empire State buildings.
However, he said: "We can't attribute the thinning of glaciers around the Amundsen Sea to global warming at this stage.

The KU research, using airplane-based radar developed at the university, showed 253 cubic kilometers of ice from a section of western Antarctica near the Amundsen Sea are moving from the glaciers each year, a volume equal to about 241,000 Empire State buildings.
If the Amundsen Sea glaciers alone were to collapse, they would raise sea levels about 4 feet, the study said.
Either way, the consequences for rising sea level may be dramatic for those living along the world's coastlines.

Glaciers flowing into another part of West Antarctica that lost their ice shelf in 2002 are indeed flowing faster, according to another study released this week.

 EO Birds Confirm Rapid Changes In Earth's Polar Ice Sheets
Large sectors of ice in southeast Greenland, the Amundsen Sea Embayment in West Antarctica and the Antarctic Peninsula are changing rapidly by processes not yet well understood, said researchers Dr. Eric Rignot of NASA's Jet Propulsion Laboratory, Pasadena, Calif., and Dr. Robert Thomas of EG&G Services at NASA's Wallops Flight Facility, Wallops Island, Va.
Radar altimetry shows ice shelves in the Amundsen Sea Embayment are rapidly thinning, possibly in reaction to a warmer ocean, as suggested by recent oceanographic data.
Continued decreases or increases could have substantial impacts on polar climates, because sea ice spreads over a vast area, reflects solar radiation away from the Earth's surface, and insulates the oceans from the atmosphere.
