A Program to Evaluate Changing Northern Lake Ice Regimes
chercheur principal: Dibike, Yonas
Année(s) de permis: 2024
Résumé: This licence has been issued for the scientific research application No. 5723. To measure ice snow depth, ice thickness and composition survey on Noell Lake in the spring. Sample locations from previous years are located using a handheld GPS. On ice snow depth is measured using a tape measure. An ice auger is used to penetrate the ice cover and evaluate if white ice is present. If present ...


A Program to Evaluate Changing Northern Lake Ice Regimes
chercheur principal: Dibike, Yonas
Année(s) de permis: 2022 2021 2020 2019 2018 2017 2016
Résumé: This licence has been issued for the scientific research application No.5155. The objective of this project is to complete on ice snow depth, ice thickness and composition survey along with collection under ice core water quality information. Sample locations from previous years are located using a handheld GPS. On ice snow depth is measured using a tape measure. An ice auger is used to pene...


Ice Bird 2019
chercheur principal: Hendricks, Stefan
Année(s) de permis: 2019
Résumé: Fundamental sea ice properties such as volume and surface characteristics change significantly within and between years. Arctic sea ice extent and thickness have undergone dramatic changes in the past decades. The strength of ice-albedo feedback mechanism depends on area-averaged ice concentration, snow and ice thickness and in summer significantly on melt pond fraction. The sea ice retreat in ...


An Integrated Sea Ice Project for BREA: Detection, Motion, and RADARSAT Mapping of Extreme Ice Features in the Southern Beaufort Sea
chercheur principal: Barber, David G.
Année(s) de permis: 2013 2012
Résumé: The objective of this study is to provide information on the thickness distribution, movement, and characteristics of different types of sea ice within the Beaufort Sea Region. The focus will be on hummocked multi-year sea ice referred to as Extreme Ice Features (EIFs). These EIFs are poorly understood, and would be the most hazardous to any engineered structure in the southern Beaufort Sea (such ...


Northern River Ice Regimes
chercheur principal: Sherstone, David A.
Année(s) de permis: 1993 1992 1991 1990 1988
Résumé: Ice gauges are installed on river ice once the ice is strong enough to support researchers (20 gauges in the Mackenzie Delta and 15 gauges on Hay River). The gauges are read every 10 days to obtain total ice thickness, white ice thickness and snow depth. From these data, the rates of ice growth and decay can be calculated, and the approximate date of maximum ice thickness can also be determined....
