Summary: The objective of this study is to collect stream silts on first order streams on a regional basis at a density of one sample every 13 Km2 across the target area. Heavy mineral concentrate samples will be collected at a density of one sample every 25 km2. The samples will be dried, labeled and shipped to various laboratories for cataloging and analysis. A team of 2 field workers would use a heli...

Summary: The aim of this study is to characterize sediment transport processes, including bed scour and fine sediment deposition, in a sub-arctic stream intersected by the proposed Mackenzie Gas Pipeline. The specific objectives of the study are: characterization of surface and sub-surface bed sediment texture for all habitat types; measurement of bed scour depth and transport distance of sediment due to ...

Summary: The purpose of this project is to develop and compile an inventory, and improve the understanding of mineral deposits related to granite intrusions in the western Northwest Territories. Understanding the concentrations of metals in the environment is im...

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: During the summer of 1997, the researchers will visit several cliff exposures of sandstone in the Mackenzie Mountains in the Carcajou Canyon (NTS 96D) and Wrigley Lake (NTS 95M) map areas, south of Norman Wells and west of Tulita, in order to obtain information on the shape of structures preserved in sandstones deposited by ancient rivers. By determining the geometry of these sandstone bodies it ...

Summary: The Mackenzie River Valley, from Wrigley to Fort Good Hope, will be surveyed in order to document the nature of the river prior to the last glaciation. Sediments will be sampled in order to determine their age (using radiocarbon dating techniques). Field work will take place along the Mackenzie River between Wrigley and the mouth of the Redstone River, in the lower section of Gt. Bear River, and...

Licensed Year(s): 1995 1993 1992
Summary: This project continues to examine the history of plant communities in the Mackenzie River and Delta regions over the past 15,000 years. Using a hand auger, core samples of sediments are taken from lake bottoms and the sediments are analyzed for the presence of pollen and diatoms. Radiocarbon dating, a technique used to estimate age, will estimate when certain species were present in the past....

Principal Investigator: MacDonald, Glen M
Licensed Year(s): 1992 1990
Summary: The research party will continue to study past climatic variation and will continue to examine the relationship between climatic change and vegetation response. They will continue lake sediment coring and will collect tree increment cores....
