Scientists from several nations are working together to launch a flagship program to explore a major mountain range buried by a large continental ice sheet and bounded by numerous subglacial lakes.
Using geophysical instruments, GAMBIT will peal back more than 600 meters of ice to explore the last hidden mountain range on Earth.

The Antarctic and Southern Ocean Data Portal provides access to geoscience data, primarily marine, from the Antarctic region.
Greenland's snowy surface has been getting darker over the past two decades, absorbing more heat from the sun and increasing snow melt, a new study of satellite data shows. That trend is likely to continue, with the surface's reflectivity, or albedo, decreasing by as much as 10 percent by the end of the century, the study says.
The fate of the ice sheets has a direct impact on populations worldwide: as the land-based ice melts, it raises sea level, and that can threaten coastal communities and economies.
Before airplanes and satellite phones, polar exploration was a more dangerous undertaking than it is now. A new article in American Scientist retraces Nansen and Shackleton's expeditions from the perspective of modern ocean conditions and sea ice drift conditions.
