Devon Canada Corporation - Marine Mammals Study for the Proposed Beaufort Sea Offshore Drilling Program
Principal Investigator: Evans, Kevin
Licenced Year(s): 2002
Summary: Five species of marine mammal regularly occur in the vicinity of the Devon exploration leases in the southern Beaufort Sea. These include beluga whale, bowhead whale, ringed seal, bearded seal, and polar bear. Other species such as narwhal, walrus and gr...

Giardia in Marine Mammals
Principal Investigator: Roach, Pat
Licenced Year(s): 1995
Summary: Samples will be initially evaluated on a presence/absence basis and taken further if warranted. The gene probe analytical technique is new and will be employed for all positive samples. Results will be published in a report format which will be submitted to FJMC to FJMC and the HTC. A paper will also be produced for publication in a refereed Journal....

Investigation of the nervous and immune systems in the beluga
Principal Investigator: Romano, Tracy
Licenced Year(s): 1993
Summary: This research will examine the nervous (i.e., brain) and immune systems of beluga by collecting these tissues from harvested animals for laboratory analyses. This study will help to determine how contaminants affect the health of belugas. In addition, the data collected may lead to a better understanding of why whales strand themselves on the shoreline as it has been suggested that beached whale...

Foxe Basin Walrus Hunt Monitoring Program
Principal Investigator: Stephenson, Tasha
Licenced Year(s): 1993 1992 1991
Summary: This project will involve the collection of data on the harvest of walrus in the Foxe Basin area. Measurements will be taken on the walrus harvested and tissue samples will be collected for the purpose of assessing contaminant levels in tissues. Hunters from Igloolik and Hall Beach will be trained in sampling techniques and the local Hunters' and Trappers' Associations will be contracted to carr...

Beaufort Sea beluga satellite tagging program
Principal Investigator: Richard, Pierre
Licenced Year(s): 1993
Summary: Beluga whales will be herded into shallow waters with boats and kept there for a short period of time. Whale size and sex will be determined and a small sample of skin will be taken for DNA analysis. Satellite tags will be attached to the dorsal ridge area of ten whales. These tags will allow the researchers to locate the whales' movements and diving patterns over the next several months....

Monitoring ringed seals in domestic harvests at Sachs Harbour, Paulatuk and Holman, NWT, in 1993
Principal Investigator: Harwood, Lois
Licenced Year(s): 1993 1992
Summary: Members of each of the communities will be hired to sample and measure the ringed seals taken in the spring and summer harvests. These monitors will be trained prior to the field season in order to collect data on the size and location of the harvests, as well as measurements on the seals harvested including sexual maturity, health, and condition. Samples of tissue taken will include jaws, lungs...

International conservation strategy for the endangered bowhead whale of Baffin Bay.
Principal Investigator: Finley, Kerry J.
Licenced Year(s): 1994 1993 1992
Summary: Since 1983, Word Wildlife Fund has supported research on the bowhead of Isabella Bay. This research, representing the first ever conducted on this species, has identified Isabella Bay to be one of the most important habitats for bowhead in the eastern arctic. The whales use the area to feed, socialize and shelter them from killer whales. The researcher will continue his study of bowhead behavi...

Assessment of potential masking of marine mammal sounds by ship noise
Principal Investigator: Cosens, Susan
Licenced Year(s): 1993 1992 1991 1990
Summary: In this final year of study, the researcher will be recording whale sounds as well as `normal' underwater sounds (background noise) and underwater sounds that boats make. The purpose of this research is to determine whether the sounds of boats interfere with the communication that occurs between beluga. The field crew will camp at Cape Lambton and make day trips to the recording sites out on the...

Biology of ringed seals and the impact of ice-breaking traffic on ringed seal biology and behaviour
Principal Investigator: Innes, Stuart
Licenced Year(s): 1993 1992
Summary: This project is a continuation of the NOGAP B.1 Marine Mammal Vessel Interaction Project. It studies the effects of ship traffic on the behaviour of ringed seals during the fast-ice period and the habitat selection of ringed seals. Seals will be located and live- trapped in order that they can be tagged and monitored. Changes in seal behaviour and distribution will be examined before, during an...

North Water Beluga Survey
Principal Investigator: Richard, Pierre
Licenced Year(s): 1993
Summary: The North Water Survey for beluga will involve the use of satellite images to locate open water, and photography to instantly record large numbers of beluga and other marine mammals sighted. Work will be conducted out of Resolute and Pond Inlet, and the survey will take in all areas of open water north of 73'00 latitude. The survey is a result of a recommendation by the 1992 Canada/Greenland Com...
