Cryoconite granules (see Figure 1) are dark, millimeter-sized aggregations of bacteria and algae, mineral particles and organic matter that form on the surface of glaciers. They are also known to be a ...

Former MCM PhD student Anna Bergstrom, pictured here at an Antarctic Family Day event, studies Cryoconite holes in the Dry Valleys. Cryoconite holes are holes in a glacier's surface caused when dirt ...

Cryoconite holes are cavities on glacial ice caused by sediment that contain diverse microbial communities in an extreme environment. These holes are formed by pieces of sediment on the ice surface, ...

Scientists have discovered that Arctic microbes are increasing the rate at which glaciers melt, in a process not accounted for in current climate change models. Working on an icecap in Svalbard, in ...

Joseph Cook took to the ice to learn about the polar ice caps of Mars, but he found something almost as otherworldly on Earth. For his graduate research in glaciology, Cook’s plan was to study ...

Glaciers have recently been recognized as ecosystems comprised of several distinct habitats: a sunlit and oxygenated glacial surface, glacial ice, and a dark, mostly anoxic glacial bed. Surface ...
