Principal Investigator: Lamoureux, Scott F
Licensed Year(s): 2010 2009
Summary: This licence is being issued for the scientific research application no. 1013. The goal of this research is to distinguish the chemical and physical processes acting on different lakes on Melville Island in order to understand how the systems have developed through time. Of particular interest is the mechanism to explain how the lakes became salty after the last glaciation. Shellabear Lake ...

Principal Investigator: Pyc, Cynthia
Licensed Year(s): 2004
Summary: Soil samples will be taken from two to three potential sump sites for the 2005 drilling program. Soil samples will provide information on active layer depth, soil composite, salinity levels, permeability and moisture content to determine sump site suitab...

Principal Investigator: Carolsfeld, Joachim
Licensed Year(s): 1996
Summary: The researchers propose to collect invertebrates, algae and microorganisms with the use of SCUBA, plankton nets, bottom dredges, and intertidal collection. These samples will be sorted and frozen for later analysis in Halifax. The researchers wish to collect samples in about 25 sites, ranging from the southern tip of Liverpool Bay to south of Saunatuk. All collections will take place from small...

Principal Investigator: Melling, Humfrey
Licensed Year(s): 1996 1995 1994 1993 1992 1991 1990
Summary: The researchers will retrieve untended sonar instruments operating beneath the sea that were positioned in April 1994. After servicing, these instruments will be re-deployed at the same locations to continue the observations for another year. A survey of water water properties will be collected at about 20 sites in the offshore and observations made using a lowered probe to 1500 m depth or to t...

Principal Investigator: Aitken, Alec E.
Licensed Year(s): 1993 1992
Summary: The researcher and his team will sample molluscs (clams, snails) using a grab sampler and a small benthic dredge. Oceanographic stations will be established in the study area to obtain measurements of water temperature, salinity and dissolved oxygen content. Animals recovered in the grab and dredge samples will be washed on a 0.5 mm sieve and preserved for identification later in the laboratory....

Principal Investigator: Dean, Ken
Licensed Year(s): 1991 1990
Summary: Satellite imagery, hydrologic data and field measurements will be used to develop a computer model of the thawing of sea ice and freezing of water in this area. The investigators will drill a hole through the ice and measure water temperature, salinity and turbidity....

Principal Investigator: Burn, Chris R
Licensed Year(s): 1990 1987
Summary: To determine seasonal frost heave regimes beneath shallow lakes in the Mackenzie Delta near Inuvik. To conduct laboratory simulation of the freezing of sea bottom sediments of varying salinities under several thermal regimes....

Principal Investigator: Frederking, R.
Licensed Year(s): 1985
Summary: Measure general environmental factors, obtain temperature and salinity profile of the ice cover; ice features will be described and documented; measure ice movements by using arrays of reflectors and an electronic distance measuring device; measure ice pressures....
