Biota are found in glaciers, ice sheets and permafrost. Ice bound micro-organisms evolve in a complex mobile environment facilitated or hindered by a range of bulk and surface interactions.

First 3-D Images of Underside of Antarctic Sea Ice
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. SeaBED, as the vehicle is […]

Antifreeze Proteins in Antarctic Fish Prevent Both Freezing and Melting
Antarctic fish that manufacture their own “antifreeze” proteins to survive in the icy Southern Ocean also suffer an unfortunate side effect, researchers report: The protein-bound ice crystals that accumulate inside […]

Life's Adaptations To Freezing and Thawing
Imagine you’re a leech, happily making a living on a turtle in some quiet, freshwater pond. What do you do when winter comes and temperatures in your warm little habitat […]

A Survivor in Greenland: A Novel Bacterial Species is Found Trapped in 120,000-Year-Old Ice
[Penn State]. A team of Penn State scientists has discovered a new ultra-small species of bacteria that has survived for more than 120,000 years within the ice of a Greenland […]

Researchers Uncover Extreme Lake — and 3000-Year-Old Microbes — in a Mars-Like Antarctic Environment
NSF-supported researchers drilling into Lake Vida, an Antarctic “ice-block” lake, have found the lake isn’t really an ice block at all. In the December 16 issue of the Proceedings of the […]
