Gazelle Lake and Point Lake Preliminary Baseline Study
Principal Investigator: Bryant, Wayne
Licenced Year(s): 1998
Summary: The Gazelle environmental baseline study will include specific investigations on water/sediment quality, lake bathymetry, limnology, catchment hydrology, fisheries and fish habitat assessment. Field data collection and observations will take about two to three days. Field staff of 3 will be transported by air to Ekati from Yellowknife. From Ekati, helicopter transport will be used to drop off the...


Fortune Minerals Nico and Dianne Lake Baseline Survey
Principal Investigator: Schryer, Rick P.
Licenced Year(s): 1998
Summary: The objective of these studies is to determine the presence or absence of fish and wildlife in the vicinity of the proposed project area. A literature search for registered archeological sites within the proposed project area is also planned. A literature review will be done to document any existing information on fish populations in the region. A preliminary survey of physical, chemical and biolo...


Persistent organic contaminants in the Great Slave Lake ecosystem.
Principal Investigator: Evans, Marlene
Licenced 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....


Investigations of presence and concentration of chlorinated organic industrial compounds and pesticides in lake sediment and fish from lakes of the Belcher Islands
Principal Investigator: Hermanson, Mark
Licenced Year(s): 1994 1993 1992 1990
Summary: We will collect and analyze sediments and fish collected from Imitavik, Annak and Kasegalik Lakes in order to assess the type and levels of contaminants present. Kasegalik Lake contains fish that are considerably different in size that those from other lakes and, since the accumulation of contaminants in fish are related to both the size and the age of the fish, it is possible that fish collected...
