Towards Long-term Monitoring of the CO2 System in Arctic Rivers
chercheur principal: Wang, Zhaohui 'Aleck'
Année(s) de permis: 2012 2011 2010
Résumé: The goal of this research is to initiate time-series measurements of the CO2 system in the Mackenzie River, the major Arctic river in North America. This work will serve as the initial step towards long-term measurements and studies of the impacts of global warming on the CO2 systems in Mackenzie River, its estuary, and adjacent coastal waters. The field campaigns will include both diurnal and...

Circumpolar Flaw Lead (CFL) System Study - Part 1 (Ship-based research)
chercheur principal: Barber, David G.
Année(s) de permis: 2008 2007
Résumé: The Circumpolar Flaw Lead (CFL) system study is designed to examine the importance of climate processes in changing the nature of a flaw lead system and the Arctic marine environment in the Northern Hemisphere, and the effect these changes will have on the marine ecosystem, contaminant transport, carbon fluxes, and greenhouse gases. Using the Canadian Research Icebreaker (CCGS Amundsen), the team ...

Impact of fire and climate change on a boreal lake
chercheur principal: Moser, Katrina
Année(s) de permis: 1993
Résumé: The researcher will collect samples of sediment and water from small lakes along Highways 5 and 6 between Fort Smith and Hay River. She will be identifying different species of diatoms (small organisms that live in the water) and conducting a number of chemical analyses on the water. Additional data will be collected on the timing of the most recent fire as well as the area's geology and plant c...
