Lake 5A Mesocosm Study - 3rd Amendment to Hydro-ecological Responses of Arctic Tundra Lakes to Climate Change and Landscape Perturbation
chercheur principal: Wrona, Frederick J
Année(s) de permis: 2010
Résumé: The overall objective of the Lake 5A mesocosm study is to better understand the impact of permafrost thaw shoreline slumping (an analogue for a warming climate) on the bottom components of the aquatic food-web in small Arctic tundra lakes in order to better predict the effects of a warming climate on food-web structure, function and productivity. To assess the direct and indirect effects of per...

Noell Lake Ice Study - 2nd Amendment to 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 component is to improve 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. All other research activities related to this work have been reviewed/approved/fully-licensed as part the overall research project “Hydro-ecological Responses of Arct...

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: Noell Lake and Lakes 5A & 5B (~ 1 km W-NW of Noell Lake) will be visited in late April to measure lake ice. Holes will be made in the ice using an ice corer. Ice thickness and composition will be determined by measuring and...
