Genetic Diversity in the Biota of Arctic Lakes
Principal Investigator: Hebert, Paul
Licensed Year(s): 1997
Summary: Our research will involve the survey of zooplankton communities in lakes and ponds of the Mackenzie Delta area (Inuvialuit private lands). Samples will be collected by either wading in ponds or by towing at net behind a float equipped helicopter. Samples will be frozen in liquid nitrogen, and subsequently examined for genetic variation. Our work aims to establish the species diversity of zoopla...


Kennedy Lake Project - 1996 Aquatic Studies
Principal Investigator: Pattenden, Rick
Licensed Year(s): 1996
Summary: The field program will be conducted during three sampling periods (spring, summer and fall). Lakes and streams in the immediate vicinity of the potential mine site will be examined. Sampling techniques will include angling, snorkeling, backpack electrofishing, beach seining, minnow traps and gill netting for fish. Plankton nets and eckman dredges will be used to collect plankton and benthic mac...


Rat River / Fish Creek Fish Hole Spring Reconnaissance
Principal Investigator: Ferguson, Brian
Licensed Year(s): 1996
Summary: Study will examine the location and extent of suitable overwintering habitat for charr in Rat River. Another objective is to document the location of spring upwellings at the overwintering site on Fish Creek. Knowledge of winter flow and temperature regimes of the spring and the effect of air temperature on the availability of overwintering habitat will provide managers with some ability to pred...


Geomorphologic analysis of the Mackenzie Delta, N.W.T. using spatial image processing.
Principal Investigator: Boyes, Donald M.
Licensed Year(s): 1995 1994 1990
Summary: The collection of the field data is required to calibrate satellite image clasifications and interpretations concerning water body measurements, plant community types, and sedimentation patterns. Field measurements will include measuring ground distances and recording plant characteristics. Nothing in the field area will be destroyed or removed....


Persistent organic contaminants in the Great Slave Lake ecosystem.
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 1995 1994
Summary: The researchers will collect samples of sediments from the bottom of Great Slave Lake at sites near Fort Resolution and Lutsel K'e. This data will allow a better understanding of how fast sediments are deposited on the lake bottom in various regions. Researchers will also collect invertebrates and fish samples as part of an overall study of contaminants in the lake's ecosystem....


Polar Ecology Field Research
Principal Investigator: Curtis, Mark A.
Licensed Year(s): 1992 1989
Summary: The research scientists and graduate students involved are primarily interested in three topics in the aquatic ecosystems of the Igloolik region: (1) the species compostion of marine phytoplankton; (2) the cold adaptation physiology of polar cod; (3) the parasites of arctic char....


Licence #5145
Principal Investigator: Neil, Elizabeth M.
Licensed Year(s): 1985
Summary: To develop and test a conceptual model tracing aquatic contaminants from dose to response. This study would also utilize data gathered under the auspices of Scientific Research License #2815 (dated May 9, 1984)....


Licence #4091
Principal Investigator: Seagel, Graham
Licensed Year(s): 1984
Summary: A study to characterize aquatic environments potentially affected by tailings decant effluent, assess their sensitivity to project influences and develop baseline data for future monitoring purposes. Water, sediment and benthic envertebrate samples will be collected for analysis. Fish will be captured for tagging and to obtain tissue samples for metal analysis (subject to approval of DFO)....


Licence #2801
Principal Investigator: McLeod, Curtis
Licensed Year(s): 1982
Summary: Conduct aquatic habitat and ecology studies....


Licence #2740
Principal Investigator: Kristensen, John
Licensed Year(s): 1982
Summary: As part of aquatic habitat and biological studies to sample fish, invertebrates, benthic stream vegetation tissue and water as well as to document aquatic habitat. Heavy Metal analysis will be carried out on the water, benthic sediments and plant tissue samples....
