Summary: This project is a continuation of work begun in 2004. The researchers were not able to do their field work in 2004, and will try again in 2005. Historic mention is made of springs at Windy Point on the north shore of Great Slave Lake. The research team...

Summary: The purpose of this study is to collect river waters to determine the concentrations of dissolved organic carbon, particulate organic carbon, and nutrients, including nitrate, phosphate and silicate, and to examine their temporary variations related to c...

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...

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...

Summary: The objective of the work is to characterize the water chemistry of lakes with reported elevated concentrations of mercury in fish from the Mackenzie River Valley, which were sampled as part of the Department of Fisheries & Oceans (DFO) fisheries management plan. This would help to establish if there is any relationship between basic lake water chemistry and mercury levels in fish which could be u...

Summary: The objectives of this research are to study the chemistry of the groundwaters that flow into the Little Fish River near the Cache Creek overwintering hole. The role of carbonate rocks is important as there is a lot of subsurface flow in this rock type. The presence of the aufeis (winter icing) on Cache Creek is a sign of groundwater flow, and is one of the reasons that this site was chosen. We...

Summary: Evaluation of the strength of methane emissions from lakes in the Mackenzie Delta relative to lakes on the adjacent arctic tundra. Will involve collecting water and sediment samples from 27 lakes in the Mackenzie Delta near Inuvik and from an additional 27 lakes located within the Havik Pak Creek and Trail Valley Creek study basins. Evaluation of diatom (algae) communities as predictors of flood...

Principal Investigator: Smol, John P
Licensed Year(s): 1994 1993 1992
Summary: The researchers plan to take samples of lake water and lake sediments from a variety of sites in the region. From these samples, information will be collected about the water chemistry, microscopic organisms present in the lakes, and changes in the region's past environmental and climatic conditions....

Summary: Characteristics of ancient sediments reveal information about the chemical, biological and physical environment within which these sediments were formed. By studying the patterns of rocks found in the north Baffin area, I hope to discover how much of the formation of these rocks was due to the algae that lived in ancient oceans, and how much was due to the chemical makeup of the water. The resea...

Summary: The researchers are interested in understanding how physical factors (snowmelt, rainfall, solar radiation) play a role in thawing the upper part of the ground each year during the spring and summer. Instruments in the ground will collect data that will estimate how much energy (from the sun) is entering into and melting the frozen ground. Other instruments will measure snowmelt, rainfall and the...
