This study compared the concentrations of perfluorocarboxylates, perfluorosulfonates, and fluorotelomer sulfonates (FTS) in biotic and abiotic samples from six high Arctic lakes...

The Cape Bounty Arctic Watershed Observatory (CBAWO) utilizes two adjacent, geologically similar watersheds, West and East, which are currently undergoing climate-driven...

We set out to examine possible links between climate warming and increases in mercury concentrations ([Hg]) in landlocked Arctic char (Salvelinus alpinus) in the High Arctic....

Data collected from landlocked char in northern Canada and Greenland indicates that 30 percent of the populations surveyed exceed toxicity thresholds for Hg in fish. Collections...

Sediment methylation and demethylation rates were measured by short-term incubations of stable isotopes of inorganic and methylmercury in sediment cores. Methylmercury...

We sampled snow of two polar desert sites (the northern coast of Ellesmere Island in the vicinity of Ward Hunt Island and Char Lake on Cornwallis Island) for molecular and...

The airborne LiDAR data were collected by NASA project partners in mid-May 2006 using a chartered Canadian Twin Otter aircraft. The acquisition system consisted of a NASA...

Sites were chosen in order to have populations of different ages and to cover, as much as possible, the environmental spectrum in which the species occurs. In plots of 10m10m (3...
