Pliocene landscape and paleoclimate change on Prince Patrick Island
chercheur principal: Gosse, John C
Année(s) de permis: 2017 2016
Résumé: 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 ...

Geophysical and geochemical investigations of massive ground ice
chercheur principal: Moorman, Brian J
Année(s) de permis: 1994 1993
Résumé: 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
chercheur principal: Burn, Chris R
Année(s) de permis: 1993 1992
Résumé: 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....
