A bstract The phylogenetic diversity of bacteria and cyanobacteria colonizing sediment
particles in the permanent ice cover of an Antarctic lake was characterized by analyses of …

Subglacial environments, particularly those that lie beneath polar ice sheets, are beginning
to be recognized as an important part of Earth's biosphere. However, except for indirect …

Lake Vida, located in the McMurdo Dry Valleys, Antarctica, is an 'ice-sealed'lake with∼ 19 m
of ice covering a highly saline water column (∼ 245 ppt). The lower portions of the ice cover …

Perennially ice‐covered lakes in the McMurdo Dry Valleys, Antarctica, are chemically
stratified with depth and have distinct biological gradients. Despite long‐term research on …

Studies of Earthly ice‐bound microbes are relevant to the evolution and persistence of life
on extraterrestrial bodies. Great diversity of icy environments make up Earth's cold …

Antarctic ice cores could preserve ancient airborne microorganisms. We examined bacteria
in two Antarctic ice core samples, an interglacial age sample from Mizuho Base and a …

An abundant and diverse bacterial community was found within brine channels of annual
sea ice and at the ice-seawater interface in McMurdo Sound, Antarctica, in 1980. The mean …

Microbiological studies of polar ice at different depths may provide important comparisons,
as they preserve records of microbial cells and past climate. In this study, we examined …

A major impediment to understanding the biology of microorganisms inhabiting Antarctic
environments is the logistical constraint of conducting field work primarily during the summer …

Lake Vostok, the largest subglacial lake in Antarctica, is separated from the surface by≈ 4
km of glacial ice. It has been isolated from direct surface input for at least 420 000 years, and …
