Characterization of Arsenic Hosting Phases in Subaqueous Tailings at Terra Mine, Northwest Territories, Canada
… Mine, an abandoned silver-copper mine in the Northwest Territories, an estimated 500,000 tons of tailings containing 540,000kg of arsenic (As) were deposited into Ho-Hum Lake. Arsenic is being released from the tailings to the overlying surface water, resulting in dissolved As concentrations …

Paleo-Ecotoxicology of Yellowknife (Northwest Territories, Canada) Lakes Impacted by Historic Gold Mining Activities
… from historic gold mining in Yellowknife lakes (Northwest Territories, Canada) using a paleo-ecotoxicological approach. I examined Cladocera subfossils preserved in the modern and pre-1850 lake sediments of 23 lakes in the region, and the Daphnia resting egg bank of Pocket Lake, a highly …

A Paleolimnological Investigation into the Ecological Impacts of Permafrost Thaw Slumping on Cladocerans (Branchiopoda, Crustacea) in the Mackenzie Delta Region (Northwest Territories, Canada)
… Crustacea) in Mackenzie Delta Region (Northwest Territories, Canada) lakes using paleolimnological techniques to answer the following questions: 1) Does thaw slumping increase UV exposure of Chydorus? 2) Are Daphnia absent in slump-affected lakes? I reconstructed UV exposure of Chydorus …

A pertographic and geochemical study of selected peridotitic and pyroxenitic xenoliths from the three kimberlite localities in the Lac de Gras region, Northwest Territories, Canada
… Misery kimberlites in the Lac de Gras region, Northwest Territories, Canada were selected for inclusion in this study. The three kimberlites are situated within a 40 km radius of one another on the BHP property, and all are diamond-bearing. The Misery kimberlite is presently being mined, and …

Remote sensing of recent changes in permafrost-influenced wetlands
… temporal scales in the Tuktoyaktuk Peninsula, Northwest Territories, Canada. Due to the presence of a statistically significant structural temporal break between the years 1997 and 1998, lake areal trends were estimated at two temporal scales, a longer term scale (1985 to 2011) and its …

Arsenic mobility in a changing northern climate: Implications for geochemical baselines and long-term stability of contaminants in lake systems
… dynamics of lake systems in northern Canada. These changes may affect the loading and cycling of naturally occurring metal(loid)s and the long-term stability of mining-derived contaminants in sub-Arctic lakes. Arsenic (As) concentrations of lakes in the Courageous Lake Greenstone Belt …

Experimental, geochemical and isotopic insights on melting and degassing behavior on Earth
… 4.0–2.9 Ga Acasta Gneiss Complex (AGC) from the Northwest Territories, Canada. These help placing constraints on the early Earth S cycle and its relation to tectonic regime. Along with other geochemical indicators, the Acasta rocks appear to record a gradual onset of subduction-like processes, …
