Principal Investigator:Reimink, Jesse R Licenced Year(s):
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...

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...

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 ...

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) ...

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...
Principal Investigator:Burn, Chris R Licenced Year(s):
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....

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....
Principal Investigator:Heaman, Larry Licenced Year(s):
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....
