Where Ice sheet, Ocean and Land Converge

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.

A National Science Foundation (NSF)-funded research team has successfully tested an autonomous underwater vehicle, AUV, that can produce high-resolution, three-dimensional maps of Antarctic sea ice.

Researchers this week published a paper confirming that the waters and sediments of a lake that lies 800 meters (2,600 feet) beneath the surface of the West Antarctic ice sheet support "viable microbial ecosystems."

Taking the Shine Off Glaciers

The first ecological study of an entire glacier has found that microbes drastically reduce surface reflectivity and have a non-negligible impact on the amount of sunlight that is reflected into space.

I am currently in the high arctic sitting (Axel Heiberg Island, Nunavut, Canada) in a tent next to the Stolz Diapir spring site at Whitsunday Bay.

Microbiologist Jill Mikucki first saw a photo of Blood Falls during a class for her master's degree at Portland State University. It immediately captivated her.

Researchers from the British Antarctic Survey and Reading University have demonstrated that, after over 1,500 years frozen in Antarctic ice, moss can come back to life and continue to grow.

We have completed our work here at Lake Obersee, accomplishing most all of our objectives despite a late start due to stormy weather.
