Arctic cod (<i>Boreogadus saida</i>) in fjord and glacial habitats: a collaborative study with Uummannap Kangerlua fishers

چکیده
Arctic cod (<i>Boreogadus saida</i>) are often found in front of glaciers, which is the least studied species' habitats. Uummannap Kangerlua and Sullorsuaq West Greenland provide a unique opportunity to study glacial habitat, as they among few places with directed fishery. Inuit fishers from these fjords regularly catch fresh bait for halibut (<i>Reinhardtius hippoglossoides</i>) longline fishery, main economic activity region. We collaborated learn about through interviews collection fish samples. Ten informants provided information on fishing areas, methods, interannual variability catches, relationships temperature sea ice, reported spawning area near Saattut. One two samples collected contained only 21% males, were longer, heavier, older, had higher gonadosomatic index than females. This skewed sex ratio may result size-selective predation or migration. Collaboration important baseline fjord Continued efforts could bring better understanding key aspects that relevant all communities located fjords.

Linking microbial diversity and functionality of arctic glacial surface habitats.
Distinct microbial habitats on glacial surfaces are dominated by snow and ice algae, which are the critical players and the dominant primary colonisers and net producers during the melt season. Here for the first time we have evaluated the role of these algae in association with the full microbial community composition (i.e., algae, bacteria, archaea) in distinct surface habitats and on 12 glac...

Glacial erosion at the fjord onset zone and implications for the organization of ice flow on Baffin Island, Arctic Canada
Organized conduits of fast ice flow at the fringe of present and past ice sheets move the majority of ice from ice sheet interior to periphery. These relatively narrow corridors play a critical role in feedbacks between landscape evolution and ice sheet dynamics. Here we combine bedrock Be concentrations with distribution of lakes on Baffin Island, Arctic Canada, to constrain the pattern of gla...
