Carotenoid diversity in novel Hymenobacter strains isolated from Victoria Upper Glacier, Antarctica, and implications for the evolution of microbial carotenoid biosynthesisDownload
Many diverse microbes have been detected in or isolated from glaciers, including novel taxa exhibiting previously unrecognized physiological properties with significant biotechnological potential. Of 29 unique phylotypes isolated from Victoria Upper Glacier, Antarctica (VUG), 12 were related to...
Ice-atmosphere interactions in the Canadian high Arctic: implications for the thermo-mechanical evolution of terrestrial ice massesDownload
Canadian High Arctic terrestrial ice masses and the polar atmosphere evolve co-dependently, and interactions between the two systems can lead to feedbacks, positive and negative. The two primary positive cryosphere-atmosphere feedbacks are: 1) The snow/ice-albedo feedback (where area changes in...
Glacier behaviour in the Karakoram region of the greater Himalaya shows strong spatial and temporal heterogeneity and, in some areas, anomalous trends compared with glaciers elsewhere in High Asia. Knowledge of the mass balance fluctuations of Karakoram glaciers, as well as of the important...
Alpine glaciers have been retreating since the Little Ice Age, leading to exposure of foreland soils. Microorganisms are the primary below ground biological influence on nutrient cycling in recently deglaciated soil and are linked to down valley vegetation colonization. Previous studies...
Although viable microbial communities have been shown to exist beneath glaciers, the impact of glacial retreat on these communities and development of the resulting foreland ecosystem is not well understood. This study investigated how microbial communities respond to changing conditions brought...
The Canadian Arctic Islands (CAI) contain the largest concentration of terrestrial ice outside of the continental ice sheets. Mass loss from this region has recently increased sharply due to above average summer temperatures. Thus, increasing the understanding of the mechanisms responsible for...
Microbial communities are responsible for biogeochemical processes in soils such as nutrient cycling and organic matter formation, which are essential to the establishment of vegetation and ecosystem sustainability. Phospholipid fatty acid analysis, microbial respiration and enzymatic activities...
Spatial and temporal variations of the surface energy balance and ablation on the Belcher Glacier, Devon Island, Nunavut, Canada.Download
In the summer of 2008 (June 2nd – September 19th) detailed measurements of meteorological conditions and glacier surface properties were conducted in the Belcher Glacier catchment (718 km2), Devon Island Ice Cap, Nunavut, Canada. These measurements were used to force and validate a distributed...
Land ice is losing mass to the world’s oceans at an accelerated rate. The world’s glaciers contain much less ice than the ice sheets but contribute equally to eustatic sea level rise and are expected to continue to do so over the coming centuries if global temperatures continue to rise. It is...
High-resolution regional climate simulations of the Karakoram, Himalaya have been performed for investigation into the atmospheric dynamics in this region, and their role in the Karakoram’s snowfall accumulation and glacial evolution. It has been seen through a combination of field measurements...
