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....

There is a clear need for air data for mercury and emerging compounds to assess temporal trends and transport pathways. Trends into the future can be effectively captured by...

A total of 9 inflow rivers/streams were sampled: 7 glacier-fed (Snow Goose River, Blister Creek, Abbé River, Gilman River, Very River, Turnabout River, Henrietta Nesmith River),...

Climatically or dynamically-driven changes in glacier mass alter the load imposed by glaciers on the underlying crust. This results in immediate vertical motion of the crust by...

Data was collected during the summer (July – August) of 2016 from Lake Hazen and its glacial inputs (Blister Creek and Snow Goose River). In addition, samples were collected...

Freshwater quality in Skeleton Lake will be analyzed by conducting water column profiles in May to early June 2017 prior to snow melt and ice decay; and, in July 2016 following...

To determine microbial community composition and their potential activities in freshwater systems throughout the Lake Hazen watershed (81N; 71W), triplicate samples were taken...

A warming climate is rapidly changing the distribution and exchanges of carbon within high Arctic ecosystems. Few data exist, however, which quantify exchange of both carbon...

Studies proposed under objectives [1] through [3] will be completed through a combination of laboratory and field-based studies. Initial emphasis will be placed on the...

Arctic char are captured by several standard methods and/or gear: experimental gillnet, back-pack electro-fisher, umbrella trap and angling gear. The following data...
