Investigations into the susceptibility of permafrost landscapes to thermokarst can be performed using various approaches, depending on the scale of investigation. In many cases,... -
Sea ice thickness in the Northwest Passage
Measurements were carried out with a towed EM probe operated by a Basler BT67 aircraft. The survey was carried out on April 8, 2016, and captured predominantly first-year fast... -
Towards a sustainable fishery for Nunavumiut (TSFN) elemental metals and tota...
Muscle samples were taken from focal species of fish and tested for 60 elemental metals. We used 25 samples of each species that was available for multiple sites. Ten samples... -
Long-term Observations of Glacier Area, Snowline Elevation, and Ice Surface E...
Glacier outlines were digitized from historical air photos (1959) and Landsat L1TP or Sentinel-2 L1C satellite imagery. Outlines for 1959-1982 were manually traced, and for... -

Detailed dissolved organic matter composition for different permafrost types ...
Organic matter, upon dissolution into the aqueous state as dissolved organic matter (DOM), can undergo mineralization by microbes. There has been increasing effort to... -
Optical properties (absorbance and fluorescence) of dissolved organic matter ...
Permafrost degradation may lead to mobilization of carbon and nutrients and enhance microbial processing rates of previously frozen organic matter. Although the pool size and... -
