Four scientists from the British Antarctic Survey (BAS) will spend 12 weeks in Antarctica, the world's largest glacier, to determine its contribution to global sea level rise, according to BAS Monday.
The expedition of four scientists who conduct 12 weeks on the glacier Pine Island, went on Monday with a polar station in the BAS Antarctic coast for 800 miles to the place where they stand camp for 12 weeks.
"The loss of ice mass in the Pine Island Glacier in the future can become a major cause of rising sea levels. We try to justify our assumptions about what will be the contribution of the glacier in the process and in what time period, it can be shown," — said the head of the expedition BAS glaciologist Andy Smith (Andy Smith).
Glacier Pine Island — one of the most interesting sites in the world for glaciologists, said BAS. The reason — the high rate of melting (ice mass each year becomes thinner more than a meter), which causes a continuous increase in the volume of runoff in the last fifteen years. Pine Island Glacier is considered a "weak spot" ice of Antarctica, as a relatively small "language" of the glacier holds back from sliding into the sea ice mass that exceeds the size of the UK.
The task of researchers — to examine the state of the ground surface beneath the ice through a variety of methods, including GPS and seismic measurements, said the BAS. Data on the underlying surface will help scientists understand what causes huge glacier "leak" at the speed of more than three miles an hour.
