Noell Lake Ice Study - Hydro-ecological Responses of Arctic Tundra Lakes to Climate Change and Landscape Perturbation
chercheur principal: Wrona, Frederick J
Année(s) de permis: 2015 2014 2013 2012 2011 2010 2009
Résumé: The overall objective of this research is to improve the knowledge on lake ice and its effect on food webs/productivity in small Arctic lake systems in order to better predict changes that could occur under changing climate. The research involves the automated ice buoy and instrumented subsurface mooring system for continuous monitoring of weather conditions, lake ice cover (formation, growth o...


Evaluation of hydro-climatic drivers of contaminant transfer in aquatic food webs in the Husky Lakes Watershed (Inuvialuit Settlement Region, NWT)
chercheur principal: Gantner, Nikolaus (Klaus)
Année(s) de permis: 2013 2012 2011
Résumé: Long term goals of this research: 1. Identify and quantify the physical, chemical and ecological processes that affect contaminant transfer in Arctic aquatic food webs in response to observed and predicted Climate Variability & Change (CVC) in the Husky Lakes Watershed (HLW). 2. Provide people and regulators of Inuvik and Tuktoyaktuk with tools to effectively monitor selected highly valued compo...

Biogeochemistry of Lakes in the Mackenzie Delta
chercheur principal: Lesack, Lance
Année(s) de permis: 2017 2016 2015 2014 2010 2009 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Résumé: Specific activities for this field season include the following: (1) Resolution of the sources and fates of dissolved organic carbon (DOC) in aquatic food webs of the Mackenzie Delta (year 3 of PhD thesis project of S. Tank). This information is needed to ultimately understand the relative role of bacterial (fueled by DOC) versus photosynthetic organisms and their importance in ultimately sup...
