Nutrient and contaminant status in the wetlands of the Slave River Delta
Principal Investigator: Doig, Lorne
Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.4988. The objectives of this project are to determine: 1) From the outer Slave River Delta (SRD) (river-water dominated) to the apex of the SRD (runoff dominated), what the current status of nutrients and contaminants in SRD wetland ecosystems are; 2) How trace elements (e.g., mercury) move through SRD wetland food webs; an...


Present and Past Hydrology, Ecology and Climate of the Mackenzie Basin Deltas
Principal Investigator: Wolfe, Brent BBW
Licensed Year(s): 2007 2006 2005 2004 2003 2002
Summary: Summer 2005 field activities will focus on continuing multi-year studies of the modern hydrology and ecology of the Slave River Delta. The aim of this research is to improve knowledge of changes in lake water balance and chemistry and the subsequent responses of aquatic plants over seasonal and inter-annual time-scales under varying climatic and hydrological conditions. Overall, this information...


Investigation of factors affecting high mercury levels in fish in lakes in the Mackenzie River Basin (2002-2003)
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2003 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...


Biogeochemistry of Lakes in the Mackenzie Delta
Principal Investigator: Lesack, Lance
Licensed Year(s): 2017 2016 2015 2014 2010 2009 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
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...


Study of bio-indicators of environmental change in arctic lakes
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....


Carbonate precipitation in the Mesproterozoic Society Cliffs Formation, Bylot Supergroup, on northern Baffin Island
Principal Investigator: Kah, Linda
Licensed Year(s): 1994 1993
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...


Wager Bay Basin Overview
Principal Investigator: Swyripa, Murray
Licensed Year(s): 1993
Summary: The Water Resources Division, along with the Inland Waters Directorate and Canadian Parks Service, are planning a cooperative water quality program for the Wager Bay area. This program will involve measuring stream flow rates and sampling for water quality at a number of sites on rivers that flow into Wager Bay within the proposed Wager Bay National Park area. As well, water and sediment samples...
