Summary: Selection of lakes for this program was based on: size (diameter/depth); fish over-wintering potential; connectivity with other waterbodies; and the likelihood of intensive (3D) seismic activity occurring within the lakes during the winter of 2001-02. A total of 6 lakes have been identified for inclusion in the survey. Three alternate lakes have also been identified in the event that those selec...

Summary: The researchers will examine the cycles in lemming abundance (i.e., increases and decreases in the lemming population) for the western arctic region. Ongoing research suggests that lemmings in the Pearce Point area do not appear to reach very high numbers as has been noted in the eastern arctic and Scandinavia. Licence issued for use of Inuvik Research Centre....

Summary: HTC members have counted, measured and sampled all fish that were caught in the domestic fishery located at the mouth of the Hornaday River for the past several years. This season represents the fourth year of the monitoring program. HTC members will collect information on arctic charr that are caught by the fishery....

Summary: Data on the distribution, abundance, survival/mortality, and productivity are essential for the sound management of wildlife populations but there is a critical lack of such information for white-fronted geese, Canada geese, Pacific brant and tundra swan populations from the Inuvialuit Settlement Region. Helicopter surveys, ground counts and banding/neck collaring will help to determine distribut...

Summary: A deflection board weir was used to assess the size of the upstream run of dolly varden charr at Big Fish River in 1991. Results suggested that migrant non-spawners may have been deterred by the weir. Consequently, the 1992 attempt to estimate run size used tagging methods at the Cache Creek site. The fish tagged at Cache Creek will be captured at the Fish Hole in the fall in order to produce a...

Licensed Year(s): 1992
Summary: This project addresses questions pertaining to the energy composition and habitat utilization of female sea-run Dolly Varden char (Salvelinus malma) of the Yukon Slope. The direct consequences of energy partitioning to fucundity (spawning success) and stored energy reserves (overwintering success) have significant effects on population abundance....

Principal Investigator: Bailey, Robert C.
Licensed Year(s): 1987
Summary: To sample the organisms living on rock surfaces (benthic invertebrates) in at least 25 streams fo the Mackenzie Delta area. The number of species present and their relative abundance will be estimated and correlated with environmental factors such as the stream size and flow rate. Habitat data will also be collected at each site....

Principal Investigator: McDonald, John W.
Licensed Year(s): 1985
Summary: To conduct bowhead whale surveys by (1) systematic aerial surveys, (2) satellite oceanography and ground truthing, and (3) photogrammetric and reconnaissance studies....

Principal Investigator: Norton, Pamela
Licensed Year(s): 1985
Summary: To monitor the white whale migration to and distribution and abundance in the Mackenzie Estuary. Secondary objectives are to observe white whale behaviour, to record whale-vessel interactions (if possible) and to quantify the number of whales missed by observers under normal survey conditions. All marine mammal sightings will be recorded....

Principal Investigator: Harwood, Lois
Licensed Year(s): 1984
Summary: To monitor the relative abundance and distribution of bowhead whales relative to oil and gas industry activities....
