Subglacial lakes are repositories of ancient climate conditions, provide habitats for life and
modulate ice flow, basal hydrology, biogeochemical fluxes and geomorphic activity. In this …

The Earth's cryosphere comprises those regions that are cold enough for water to turn into
ice. Recent findings show that the icy realms of polar oceans, glaciers and ice sheets are …

We describe the history and features of the Ladder of Life Detection, a tool intended to guide
the design of investigations to detect microbial life within the practical constraints of robotic …

Liquid water has been known to occur beneath the Antarctic ice sheet for more than 40
years, but only recently have these subglacial aqueous environments been recognized as …

The tundra is the coldest biome described in typical geography and biology textbooks.
Within the cryosphere, there are large expanses of ice in the Antarctic, Arctic and alpine …

There is now compelling evidence that microbially mediated reactions impart a significant
effect upon the dynamics, composition, and abundance of nutrients in glacial melt water …

At a hole in lake ice, a painting from the year 1900 by Finnish artist Pekka Halonen (1865–
1933), who is well known especially of his winter landscapes. In cold regions the normal life …

Cassini revealed that Saturn's Moon Enceladus hosts a subsurface ocean that meets the
accepted criteria for habitability with bio-essential elements and compounds, liquid water …

The composition of fungal and bacterial communities in three polythermal glaciers and
associated aquatic environments in Kongsfjorden, Svalbard was analysed using a …

“Biogeophysics” is a rapidly evolving Earth science discipline concerned with the
geophysical signatures of microbial interactions with geologic media. It spans the …
