Summary:
The field work in Trail Valley Creek and Inuvik aims to study: 1) how catchment characteristics, such as vegetation and soil properties, control the amount and quality of aquatic dissolved organic matter (DOM) and its microbial degradability, and 2) how these factors further regulate greenhouse gas fluxes (carbon dioxide CO2, methane CH4, nitrous oxide N2O) from Arctic lakes.

Summary:
The specific objectives of this project are:
1) to document trends in export of coastal, riverine and subterranean dissolved and particulate organic matter and carbon into the Arctic Ocean;
2) to determine their fate and related processes (origin and age, transport, physical, chemical, and biological transformation) in coastal waters and estuarine sediment; and
3) to assess the impacts of thes...

2018 Summary:
The seven-year objective of Sub-Arctic Meteal Mobility Study (SAMMS) is to identify, quantify, and predict mobility of natural-source and legacy mine-source metals in soil, wetlands, and lake sediments that extend from former, present, and planned mine sites currently and as climate change alters the quantity and quality of dissolved organic matter produced and exported in subarctic NWT watersheds...
