Carbon and trace metal transfers in the Mackenzie Delta region
chercheur principal: Hilton, Robert G
Année(s) de permis: 2024 2023
Résumé: This licence has been issued for the scientific research application No. 5624. The main goal of this research is to better understand how greenhouse gas emissions from rivers will impact the future trajectory of atmospheric carbon dioxide (CO2) and methane (CH4) concentrations. The research team has identified two key research objectives that will allow them to address major research gaps i...


Airborne Observations in Support of NETCARE
chercheur principal: Abbatt, Jon
Année(s) de permis: 2015
Résumé: The NETCARE observations will be covered the range from Longyearbyen, Svalbard (European Arctic) until Inuvik (NWT – Polar 6 aircraft only) and Barrow (Alaska – Polar 5 aircraft only). The observational platforms will be two aircraft: 1) the Alfred Wegener Institute (AWI) POLAR 5, a modified DC-3 aircraft; and 2) the AWI POLAR 6, also a modified DC-3 aircraft. The two platforms will be coordin...


Aerosol Chemical Composition in the Arctic (ACCA), a subproject to RACEPAC
chercheur principal: Borrmann, Stephan P
Année(s) de permis: 2014
Résumé: The objectives of this research project are: (1.) To perform in-situ measurements of number concentrations, optical properties, and chemical composition of atmospheric aerosol particles with sizes between 3 nanometers and 10 micrometers. (2.) Identify aerosols of natural and anthropogenic origin. (3.) Quantify their relative contributions in dependency of particle size. (4.) Evaluate the pot...


Radiation – Aerosol – Cloud Experiment in the Arctic Circle (RACEPAC)
chercheur principal: Ehrlich, André
Année(s) de permis: 2014
Résumé: These research activities combine investigations of clouds and atmospheric aerosol in the Beaufort Sea. The main aim of the cloud studies is to improve the understanding of the cloud-related processes in the Arctic atmosphere and to use these measurements to improve the performance of regional and global climate models of the Arctic. To understand cloud processes knowledge on aerosol properties wh...


Airborne measurements of methane (AIRMETH)
chercheur principal: Sachs, Torsten
Année(s) de permis: 2016 2013 2012
Résumé: The objectives of this study are to quantify the surface-atmosphere methane emissions over large areas, and to analyze the influence of different surface and vegetation characteristics on large area methane emissions (process understanding). The research team proposes to measure methane fluxes between the tundra and the atmosphere by airborne eddy covariance, a micro-meteorological method. Flux...


Polar Airborne Measurements and Arctic Regional Climate Model Simulation Project
chercheur principal: Herber, Andreas
Année(s) de permis: 2011 2009
Résumé: The main aim of these weather and air quality studies is to improve the understanding of the processes in the Arctic atmosphere and to use these measurements to improve the performance of regional and global climate models of the Arctic. The aim of the sea ice studies is to obtain a snapshot of ice thickness in a vast region of the Arctic, and to create an inventory of Arctic sea ice volume. Th...


Wind Energy Monitoring in Tuktoyaktuk NWT
chercheur principal: Seccombe-Hett, Pippa
Année(s) de permis: 2008 2007
Résumé: The objective of this wind monitoring proposal is to quantify wind energy potential for the economic feasibility of building a wind farm in Tuktoyaktuk. This year the proposed project will involve maintaining data collection at the wind monitoring site, as well as data analysis and reporting. The Tuktoyaktuk wind monitor will visit the wind tower site monthly and maintain the monitoring site e...


Impact of melt ponds on energy and momentum fluxes between atmosphere and sea ice (acronym: MELTEX)
chercheur principal: Birnbaum, Gerit
Année(s) de permis: 2008
Résumé: The main goal of this project is to better understand how melt ponds evolve, and their influence on absorption/reflection of solar radiation at the sea ice surface. This information will help to predict summer sea ice melt and future Arctic climate. Data will be collected by using instruments mounted on the German research aircraft Polar5. The airbase of Polar5 will be Inuvik. The aircraft will...


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 ...


Increasing Boreal Forest Fire: Future Impacts on Arctic Environment and Climate
chercheur principal: Stocks, Brian J
Année(s) de permis: 2007
Résumé: The research aims to characterize the physical and chemical properties of forest fire smoke and its impact on the Artic. Three aircraft (CT-133 jet, Dehavilland Sea Heron and Dehavilland Twin Otter) based out of Yellowknife, equipped with standard scientific atmospheric chemistry sampling instrumentation, will be used to sample smoke while airborne. Sampling will take place opportunistically as fi...
