Pliocene landscape and paleoclimate change on Prince Patrick Island
Principal Investigator: Gosse, John C
Licensed Year(s): 2017 2016
Summary: The objectives of this research are to: 1) collect pieces of wood to measure tree rings and carbon and oxygen isotopes to determine past climate (mainly average summer temperature); 2) collect sand samples to date the layers which contain the wood and evidence of faulting, so the team can date they can be dated to show how old the wood and faults may be; 3) map the faults and tilting of the ...

Exploration of the Earliest Crust Forming Events on Earth
Principal Investigator: Reimink, Jesse R
Licensed Year(s): 2016
Summary: This project will use radioactive isotope systems, whole rock isotopic measurements, and isotope data for zircons to investigate the role Hadean (> 4 billion year (Ga) old) crust played in the genesis of the Slave craton of the Northwest Territories, Canada. Data of this nature for rocks from the best-studied locality in the Slave craton, the Acasta Gneiss Complex, show that these circa 3.8-4.02 G...

Examining the Acasta Gneiss Complex: A Broader Scope
Principal Investigator: Belosevic, Mike
Licensed Year(s): 2016 2015
Summary: This study is designed to encompass the following goals: 1) Collect samples from the expanded Acasta Gneiss Complex (AGC) study area; 2) Perform field mapping and general exploration of the expanded study area; 3) Perform age dating and isotopic analysis of the collected samples along with whole-rock geochemistry to compare data with those in the extensively studied AGC body adjacent to the Acasta...

Monitoring of mercury, flame retardants and other chemicals in lake trout and cisco from Great Bear Lake
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2016 2015 2014 2013
Summary: This study is designed to find out whether contaminant levels are changing in fish (lake trout and cisco) in Great Bear Lake. The research team require fall-caught fish for this study. Twenty whole lake trout and 20 whole cisco of a range of sizes are required from Great Bear Lake. The fish will be frozen immediately after capture and shipped to Environment Canada-Saskatoon. The fish will then ...

Petrogenesis of the Acasta Gneiss Complex: Ancient Rocks Revisited
Principal Investigator: Reimink, Jesse R
Licensed Year(s): 2014 2013 2012 2011
Summary: The present study aims to obtain information with the following objectives: 1) further describe, sample, and document field relationships and structures present in areas that were sampled and found to be significantly old (>3.8 billion years); 2) explore and sample other units which based on field relationships and mineralogy are likely to be as old or older than previously documented samples; 3) ...

Geophysical and geochemical investigations of massive ground ice
Principal Investigator: Moorman, Brian J
Licensed Year(s): 1994 1993
Summary: The researchers will conduct 2 types of surveys: (1) radar surveys will be conducted using a portable radar unit; and (2) small samples of ice from glaciers and moraines will be collected in order to conduct analysis which will determine the chemical make-up of the ice. This information will be used to determine characteristics about the glaciers as well as help in our understanding of the climat...

Spatial variation in the isotopic composition of snowpack in the Mackenzie Delta area
Principal Investigator: Burn, Chris R
Licensed Year(s): 1993 1992
Summary: This on-going research involves the assessment of isotopes in snowpack each winter. Collection of snow and ice at various sites along winter roads in the N.W.T. provides information about the composition of isotopes within a region. Isotopic composition of snow and ice taken from ice cores in Greenland and Antarctica have been able to provide information about past climates....

Estimation of Atmospheric Fluxes of Polychlorinated Biphenyls (PCB) and Pesticides to the Southern Hudson Bay Region by Analysis of Dated Lake Sediments
Principal Investigator: Hermanson, Mark
Licensed Year(s): 1994 1993 1992 1990
Summary: The Researcher and his assistant will collect sediment cores from two lakes (Annak and Imitavik) in the Sanikiluaq area. Cores will be sliced into horizontal sections and will be analyzed for radioisotopes used to identify ages of the sediment layers. The sections will also be analyzed for organic compounds....

U-Pb Geochronology and Isotope Systematics of Kimerlites and their Mantle Zenoliths
Principal Investigator: Heaman, Larry
Licensed Year(s): 1990
Summary: The Researcher and team will conduct a geological investigation of kimberlites on the NE side of Somerset Island. They will collect samples of Somerset Island kimberlites to provide information concerning their timing, origin and isotopic evolution. The data will be added to a North American database for a better understanding of the isotopic nature of the Earth's mantle on a global scale....

Licence #2381
Principal Investigator: Fontes, J.c.
Licensed Year(s): 1978
Summary: To collect water samples for isotopic analysis of dissolved carbonates....
