NSF funded Antarctic Drilling Team finds new ecosystem
NSF-funded antarctic drilling team--first to bore through hundreds of meters of ice to where ice sheet, ocean and land converge--finds a new ecosystem
Using a specially designed hot-water drill to cleanly bore through a half mile of ice, a National Science Foundation (NSF)-funded team of researchers has become the first ever to reach and sample the "grounding zone," where Antarctic ice, land and sea all converge. Data gathered from samples of sediment taken in the grounding zone will provide clues about the mechanics of ice sheets and their potential effects on sea-level rise.
Cameras sent down the drilling hole also revealed an unsuspected population of fish and invertebrates living beneath the ice sheet, the farthest south that fish have ever been found. The surprising discovery of fish in waters that are extremely cold at -2 Celsius (28 degrees Fahrenheit) and perpetually dark poses new questions about the ability of life to thrive in extreme environments.
