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 …

Glaciers and Glaciation is the classic textbook for all students of glaciation. Stimulating and
accessible, it has established a reputation as a comprehensive and essential resource. In …

Patterns of environmental spatial structure lie at the heart of the most fundamental and
familiar patterns of diversity on Earth. Antarctica contains some of the strongest …

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 …

Glacier ecosystems are teeming with life on, beneath, and to a lesser degree, within their icy
masses. This conclusion largely stems from polar research, with less attention paid to …

An active microbial assemblage cycles sulfur in a sulfate-rich, ancient marine brine beneath
Taylor Glacier, an outlet glacier of the East Antarctic Ice Sheet, with Fe (III) serving as the …

Viable microbes have been detected beneath several geographically distant glaciers
underlain by different lithologies, but comparisons of their microbial communities have not …

Moreover, the shared sensitivity of glacial and glacier-affected biodiversity to climate
warming, as well as the interactions between glacial and glacier-adjacent ecosystems …

The basal regions of continental ice sheets are gaps in our current understanding of the
Earth's biosphere and biogeochemical cycles. We draw on existing and new chemical data …
