Hydrology of Northern Latitudes
chercheur principal: Marsh, Philip
Année(s) de permis: 2024
Résumé: This licence has been issued for the scientific research application No. 5842. The objectives of this project are to: (1) develop improved understanding of, and ability to predict, the complex northern hydrologic system, (2) consider the integrated effect of the changing climate on vegetation, snow, permafrost, streamflow, and lakes, and (4) develop improved water models needed to predict futur...

THAWPOND-NWT – Remote sensing analysis of vegetation and thaw pond colour dynamics in the continuous permafrost zone: from local to regional (Northwest Territories, Arctic Canada)
chercheur principal: Vieira, Gonçalo
Année(s) de permis: 2023
Résumé: This licence has been issued for the scientific research application No. 5639. The goal of this research project is to better understand the characteristics of various different lakes, how their characteristics vary, as well as their potential relation to permafrost thaw events in the recent or distant past. The frequency of occurrence across space and time as well as the variability of: 1) opt...

Improving Habitat Connectivity to Enhance Productive Capacity of Arctic Freshwater Ecosystems
chercheur principal: Tonn, William
Année(s) de permis: 2014 2013 2012 2011 2010 2009
Résumé: The objectives of this research project are: to study the freshwater ecology, hydrology, and hydraulics of small lakes and streams in the Lac de Gras basin before habitat modification; to monitor the changes in ecosystem productive capacity resulting from habitat modifications designed to increase habitat connectivity and fish passage; and to assess the effectiveness of such habitat modifications ...

Hydro-ecological Responses of Arctic Tundra Lakes to Climate Change and Landscape Perturbation
chercheur principal: Wrona, Frederick J
Année(s) de permis: 2011 2010 2009
Résumé: The overall objective of this study is to develop a model that can be used to look at the vulnerability of small arctic lakes and ponds to changing climate. Lake Ice Study: Lakes 5A, 5B and Noell Lake (MAP-2 of the original licence application) will be visited in mid-April to measure lake ice. Holes will be made in the ice using an ice corer. Ice thickness and composition will be determined by...

Sensitivities of high-latitude lakes to climatic & development disturbances
chercheur principal: Prowse, Terry D
Année(s) de permis: 2008 2007 2006 2005
Résumé: The objective of this study is to develop a hydro-ecological model for small Arctic lakes to assess the vulnerability of their ecosystems to disturbances, such as climate change or water withdrawal. To quantify geochemical loadings to lakes, a model is being developed by monitoring lakes and their contributing catchment (surface water flow). A climate station will be set up at 2 - 6 sites to mo...

Modelling the energy and water balance and characteristics of lakes in the Mackenzie River Basin.
chercheur principal: Rouse, Wayne R
Année(s) de permis: 2001
Résumé: The field work associated with the proposed study will consist of the collection of climate data, such as air temperature, humidity, wind speed, wind direction, amount of rain fall, water temperatures and light penetration into the lake. Similar equipment will be used to collect this data at all sites. Air temperature, humidity, wind speed, wind direction, water temperatures and light penetration...

The Chemical and Physical Limnology of Truelove Lowland, Devon Island, N.W.T.
chercheur principal: Robilliard, L.J.
Année(s) de permis: 1992
Résumé: In 1991, lake, pond and inlet water at Truelove Lowland, Devon Island was sampled to provide a limnologic description of this particular High Arctic setting. The objective is to group the lakes on the basis of various chemical and physical properties. The project will continue in 1992....
