But now, according to satellite images, a big piece of that Greenland coastal ice
suddenly vanished or was reduced to floating bits and slush.
Since then, Labrador's coastal ice
has declined by almost 40 percent, making travel treacherous, if possible at all.
Given the continent's surface area, this could in fact offset the loss of coastal ice
and thus drastically reduce the ice continent's contribution to the rising sea level.
In particular, it would be valuable to improve our understanding of coastal ice
mobility and projections of freeze-up and breakup dates (and length of the open water season) as a function of regional climate projections.

shelves and the glaciers behind them.
To improve our understanding of ice-land interaction, first-order mathematical models are presented for the analyses of the evolution of the coastal ice
(12) Coastal ice
shelves (portions of the ice sheet that hang out over the oceans) buttress the seaward flow of ice from the continent, but geological history suggests a drastic change is possible.
Bespoke adventures on the trip include kite skiing, rock and ice climbing, abseiling into crevasses, 4x4 adventures to the coastal ice
barrier or to one of the science bases, a flight to the South Pole as well as access to a 12,000-strong colony of fearless emperor penguins and their hatchlings -- one of the most rarely seen wildlife events on the planet.
In the towns of Shishmaref and Newtok, melting coastal ice
and permafrost have caused erosion and flooding.
"In 2005, we had summer melting occurring inland as well as over the coastal ice
shelves, and over areas up to 2500 metres above sea level," said Tedesco.
The expedition's mission is to hug the path of open water, called the "flaw lead," between the central sea ice pack--the ice that builds up and moves south from the Polar Ice Cap--and the coastal ice
, a place particularly sensitive to environmental changes.
Beach width (the distance between the lake edge and the foredune) was measured in meters and the presence of any coastal ice
