Summary: The researchers will continue their study, begun in 1993, on the pegmatites found in the Selwyn Mountains and other western Canadian locations. Pegmatites contain rare elements such as lithium, beryllium, ribidium, niobium, cesium and talalum. This study will result study will result in a summary of information on pegmatites, including detailed information on their classification, origins and...

Summary: Data collection for food habits analysis will involve collection and analysis of bear scats and will be supplemented by direct observation of bears in the field. Where feeding or other sign (e.g., mark tree, digging, tracks) site investigations will be carried carried out involving recording inventory, cover value and phenology of all potential bear foods present and taking measurements pertinent...

Summary: Soil (at seven depths) and air temperature data are recorded by data loggers. These loggers are programmed to collect data every 3 hours on the hour. The sites are visited twice a year to reprogram the loggers. In addition, active layer depth and subsidence are also recorded during the fall visit. Researchers will collect this data in order to determine the effect of climate change on the envi...

Summary: The researchers will continue their monitoring of ice formation and breakup at the Mackenzie River crossing near Fort Providence. Data will be collected on water levels, river velocity, ice thickness and strength, and snow depth. This information will contribute to our knowledge of ice formation and breakup at this crossing, with a goal of predicting freezeup and breakup events....

Principal Investigator: Swyripa, Murray
Licensed Year(s): 1993
Summary: Northward flowing rivers are thought to be major ways in which contaminants are introduced to the Arctic Ocean. As part of an on-going study, river water and sediments will be collected over the course of the year and assessed for the presence of contaminants. A total of 12 rivers in the Canadian arctic mainland will be sampled in this study, including the Mackenzie, Coppermine, Burnside, Ellice...

Principal Investigator: Gregor, Dennis J.
Licensed Year(s): 1993
Summary: Contaminants are carried in the air to the arctic during the winter when large-scale wind movements bring these contaminants from industrialized locations in North America, Europe and Asia to the north. Snow can collect these compounds from the air and bring them to the ground where they can accumulate. Thus, it is important to study the amount of contaminants in snow to determine the types and ...

Principal Investigator: Staple, Tamara
Licensed Year(s): 1993
Summary: The research in Nahanni National Park includes the setting up of programs to monitor water depth and vegetational changes along the river. Changes in water depth influence the ability of navigating the river, especially in areas of rapids, and has implications on the level of expertise required by visitors travelling the river. Monitoring vegetation along the river will provide information about...

Principal Investigator: Maffey, Murray
Licensed Year(s): 1993 1992
Summary: This ongoing project has several activities associated with the study of fire ecology in the N.W.T.. The researchers are involved with the collection of data at a prescribed burn site located at Little Rat Lake (Hook Lake) near Ft. Resolution. They are also participating in the fire history study in the Mackenzie Bison Sanctuary. Finally, crew leaders from the Ft. Simpson initial attack teams w...

Summary: Ice gauges are installed on river ice once the ice is strong enough to support researchers (20 gauges in the Mackenzie Delta and 15 gauges on Hay River). The gauges are read every 10 days to obtain total ice thickness, white ice thickness and snow depth. From these data, the rates of ice growth and decay can be calculated, and the approximate date of maximum ice thickness can also be determined....

Principal Investigator: Johnston, Paul A.
Licensed Year(s): 1992
Summary: The researcher and his team will look for fossils of reef animals. Notes will be taken on the growth positions of the reef animals, and about 400 kg of fossils will be collected by hand or with hammers and chisels from various localities. The fossils will be brought back to the Royal Tyrrell Museum and used to make molds. Casts from these molds will be used to make an exhibit showing a three-di...
