The Arctic is warming–fast. Microbes in the Arctic play pivotal roles in feedbacks that magnify
the impacts of Arctic change. Understanding the genome evolution, diversity and dynamics …

Microbial mats are ubiquitous in polar freshwater ecosystems and sustain high
concentrations of biomass despite the extreme seasonal variations in light and temperature …

The ice shelves along the northern coast of Ellesmere Island have been in a state of decline
since at least the early twentieth century. Available data derived from explorers' journals …

Cyanobacteria are commonly found in freshwaters, soils and glacial environments in polar
and alpine regions. Studies to date indicate these cold-dwelling phototrophs are …

Cyanobacterial mats are commonly reported as hotspots of microbial diversity across polar
environments. These thick, multilayered microbial communities provide a refuge from …

The Ellesmere ice shelves are located on the northernmost edge of Canada, the northwest
coast of Ellesmere Island, facing the perennial pack ice of the Arctic Ocean. They are the …

A review of historical literature and remote sensing imagery indicates that the ice shelves of
northern Ellesmere Island have undergone losses during the 1930s/1940s to 1960s, and …

A depression running across the outer Milne Ice Shelf was hypothesized to overlie a basal
channel incised by outflow from the Milne Fiord epishelf lake, a thick layer of freshwater …

Synthetic aperture radar (SAR) satellite imagery was used to reconstruct the change in
limnological conditions adjacent to an Arctic ice shelf by examining the backscatter values of …

Abstract The Eastern Canadian Arctic contains over a third of the world's Arctic glaciers and
ice caps, and the last remaining ice shelves in the Northern Hemisphere. These components …
