Improved measurements of Arctic snowfall using a novel interdisciplinary approach (A-Snow) - Atmospheric science component
chercheur principal: Thériault, Julie Mireille
Année(s) de permis: 2024
Résumé: This licence has been issued for the scientific research application No. 5743. The objective of this proposal is to develop a next-generation method to accurately measure Arctic snowfall under a range of environmental conditions typical across the Arctic. The specific objectives are: 1) Measure key snowfall parameters using state-of-the-art instruments as required to estimate snowfall during t...


IceBird Winter 2023
chercheur principal: Krumpen, Thomas
Année(s) de permis: 2023
Résumé: This licence has been issued for the scientific research application No.5486. IceBird Winter 2023 is part of a long-term sea ice observation program within the IceBird aircraft campaign series. IceBird was initiated in 2018 with the objective to ensure the long-term availability of a unique data record of direct sea-ice thickness observations to understand the role of the sea ice component for ...


CEAS
chercheur principal: Rutter, Nick
Année(s) de permis: 2022
Résumé: This licence has been issued for the scientific research application No.5463. The objectives of this project are to develop improved understanding of, and ability to predict, snowcover properties from numerical models used to simulate climate and hydrology in northern regions; to consider the integrated effect of climate on vegetation, snow, permafrost, and lakes; and, to develop improved predi...


Hydrology of High Latitude Watersheds
chercheur principal: Marsh, Philip
Année(s) de permis: 2023 2022 2021 2020 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006
Résumé: This licence has been issued for the scientific research application No.5496. The objectives of this project are: 1) to develop improved understanding of, and ability to predict, snowcover formation and melt, as well as stream discharge in northern regions; 2) consider the integrated effect of climate on vegetation, snow, permafrost, streamflow, and lakes; and 4) develop improved predictive mod...


Snow compaction and permafrost monitoring
chercheur principal: Wilson, Alice
Année(s) de permis: 2023 2022 2021 2020
Résumé: This licence has been issued for the scientific research application No.5475. The primary objective of this research is to determine the influence of snow manipulation on permafrost temperatures in different environments along the Inuvik to Tuktoyaktuk Highway (ITH). A secondary objective is to better understand the relationship between snow cover and ground surface temperatures in both natural...


Radar Satellite Observations of Lake Ice Breakup and Freeze-up
chercheur principal: Drouin, Hugo
Année(s) de permis: 2020 2019
Résumé: This licence has been issued for the scientific research application No.4648. This project aims to evaluate and develop the utility of Canada’s future RADARSAT Constellation Mission (RCM) (launch June 2019) for the monitoring of lake ice breakup and freeze-up. RCM-type radar images will be simulated using data from Canada’s current radar satellite – that is - RADARSAT-2. Validation data in the ...


Lake and River Ice Fieldwork in support of PermASAR data analysis
chercheur principal: van der Sanden, Josephus J
Année(s) de permis: 2019
Résumé: This project aims to undertake fieldwork in the context of the PermASAR winter campaign. The data collected will support the evaluation and development of radar satellite Earth observation (EO) technology for application to the mapping of river and lake ice processes and properties. The research team expect the fieldwork to take place over a period of two to three weeks in the months of Februar...


Influence of the Arctic on Mid-latitude Weather and Climate: Observation of Precipitation Particles at Inuvik.
chercheur principal: Yamashita, Akira
Année(s) de permis: 1995
Résumé: The researchers will observe crystal formation from ice fog through the collection of samples for microscopic observation and through the taking of photographs/video of optical phenomena produced by floating ice crystals. Particle counting and cloud condensation nucleus counting at the observation site will also be done....


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....


Snow Melt Runoff in High Latitude Permafrost Basins
chercheur principal: Marsh, Philip
Année(s) de permis: 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1990
Résumé: The research project will include measuring the amount of snow on the ground, changes in snow properties during spring melt, weather conditions and runoff in nearby rivers. The purpose of the project is to improve ability to predict smowmelt runoff to rivers and lakes in Northern Canada....
