2012 Summary:
This study will examine the solar degradation of riverine dissolved organic carbon (DOC) to carbon dioxide (CO2) throughout the Mackenzie River Delta. During the spring runoff peak just before summer solstice, ice-jam flooding inundates the Delta with river water, which spreads out in a relatively thin layer over an extended area and is exposed to 24-hour Arctic sunlight. This water is then slowly...

The Arctic Great Rivers Observatory project studies the six largest rivers in the Arctic; the Mackenzie and Yukon Rivers in North America and the Ob', Yenisey, Lena, and Kolyma Rivers in Russia. The research team is interested in how climate change is impacting Arctic rivers. The team will make measurements of the concentration of naturally-occurring chemicals (like carbon and nitrogen) and try to...

2010 Summary:
The goal of this research is to initiate time-series measurements of the CO2 system in the Mackenzie River, the major Arctic river in North America. This work will serve as the initial step towards long-term measurements and studies of the impacts of global warming on the CO2 systems in Mackenzie River, its estuary, and adjacent coastal waters.
The field campaigns will include both diurnal and...

1998 Summary:
This study is based on earlier research conducted by the Department of Fisheries and Oceans which found that fish in many lakes in the Mackenzie River Basin had high mercury concentrations. This study examines the environment in which the fish live in o...

2000 Summary:
The crew will fly from Yellowknife to the Tundra Ecosystem Research Station camp on Daring Lake from BHP (Ekati Mine) by helicopter. The research team itinerary consists of: (1) setting up the camp; (2) sampling all of the major streams flowing into Daring Lake for chemistry and instantaneous flow; (3) walking through several basins to decide on an intensive sampling site; and (4) installing dri...

Field work for this ongoing project involves taking measure- ments of snow accumulation (from the previous winter) and meltwater accumulation (from the spring) for the White and Baby Glaciers. Changes in the size of the glaciers can provide information about whether the climate is warming. Colour Lake is being investigated because its water is acidic: data will be collected to determine the rea...

Summary:
In 1991, lake, pond and inlet water at Truelove Lowland, Devon Island was sampled to provide a limnologic description of this particular High Arctic setting. The objective is to group the lakes on the basis of various chemical and physical properties. The project will continue in 1992....
