The Use of Sediment Data as an Indicator of Aquatic Ecosystem Health in the Coppermine River Basin, NWT
Principal Investigator: Peramaki, Liisa
Licensed Year(s): 2000
Summary: This study will investigate the quality of aquatic sediment and evaluate its potential as an indicator of ecosystem health in the Coppermine River basin. Sediment cores will be collected by boat or float plane at Lac de Gras and Point Lake. The following field measurements will be recorded: water temperature and pH, and sediment colour, texture and pH. In addition, personal interviews will be c...

The origin of deformed massive ice, Pleistocene Mackenzie Delta, Western Canadian Arctic
Principal Investigator: Murton, Julian B
Licensed Year(s): 1999 1998
Summary: The main objective of the proposed research is to establish the origin of massive bodies of underground ice at two key massive-ice localities in the Mackenzie Delta area: i) Cliff Point, Liverpool Bay and (ii) near Eskimo Lakes. The research will be carried out by an interdisciplinary team of scientists examining the geology, glaciology and chemistry of the ice and adjacent sediments. The research...

Mercury Concentration of Two Lakes on the Yellowknife River System Affected by the Bluefish Hydrodam
Principal Investigator: Puznicki, Wayne
Licensed Year(s): 1997
Summary: The objective of the study is to assess the concentration of mercury in fish, water and sediment in Bluefish and Duncan Lakes; to provide information to the Yellowknives Dene First Nation to make decisions relating to the use of fish and water from these lakes; and to correlate traditional knowledge with scientific data. Bluefish & Duncan Lakes are about 50 km to the northeast of Yellowknife. Tr...

Hydrology and geomorphology studies on the Slave River Delta, N.W.T.
Principal Investigator: English, Michael C
Licensed Year(s): 2000 1996 1995
Summary: The researchers will examine three things. The first is areas of landform change since 1977. Landforms will be surveyed and sediment sampled in order to measure how much sand, silt and clay are in the deposits. Second, the researchers will analyze the sediment for different chemicals wihich originate from the Slave River and third, measure the elevations of channels along their entire length, me...

Environmental Monitoring Study - Lupin Mine
Principal Investigator: d'Entremont, Andre
Licensed Year(s): 1991 1990
Summary: A sampling program will be undertaken where sediment and benthic organisms will be collected at six sites sampled in 1985. The samples will be analysed to determine if any statistically significant changes in the sediment chemistry and species diversity and abundance have occurred since the mine began operation in 1985....
