Biogeochemical controls on the structure and functioning of low arctic ecosystems
Principal Investigator: Grogan, Paul
Licenced Year(s): 2016 2015 2014 2013 2012 2011 2010 2009 2008
Summary: The long-term goal of my research over the next 15-20 years is to substantially advance the understanding of how Canadian arctic tundra ecosystems function, and therefore how they are likely to be affected by these perturbations. This research will work to answer the following questions: 1) Apart from birch, which other species within the mesic tundra plant community also have their growth c...


Soil microarthropod community responses to climate change
Principal Investigator: Turnbull, Matthew S
Licenced Year(s): 2013
Summary: The goal of the principal investigator is to assess the diversity of species and functional traits of microarthropods in the Canadian arctic. The Canada Tundra Ecosystem Carbon Study (CTECS) was selected as a research site because there have been running temperature, moisture, and nutrient addition treatments since 2004 with the goal of simulating climate change and predicting its effects on plant...


eSpace - Emergency Spatial Pre-SCAT for Arctic Coastal Ecosystems
Principal Investigator: Duffe, Jason A
Licenced Year(s): 2012 2011 2010
Summary: The objectives of this study are to: (1) Fly oblique helicopter videography for two study sites (i.e. the outer Mackenzie River Delta and Kugmallit Bay) and collect field data at various locations, as identified in the map provided. (2) Interpret helicopter videography and create an Environmental Sensitivity Index map. This will consist of a vector file of shoreline types, which will be drawn on...


Climate Change Impacts on Canadian Arctic Tundra Ecosystems - Metis Traditional Knowledge Study
Principal Investigator: Grieve, Sheryl
Licenced Year(s): 2010 2009 2008 2007
Summary: This project is part of a larger IPY study, CiCAT, that is looking at the effect of climate change on arctic tundra ecosystems. The researchers will be collecting Métis traditional knowledge on vegetation and terrain changes in the North Slave region. In addition, they will be collecting and commenting on the scientific methodology for the larger CiCAT project. They hope to provide an integral c...


Dall’s Sheep, Grizzly Bears and Wolves interactions in the Gwich’in Settlement Area: Traditional Knowledge and Climate Monitoring
Principal Investigator: Lambert Koizumi, Catherine
Licenced Year(s): 2010 2008 2006
Summary: The proposed project aims to: 1) update and expand important baseline information on Dall’s sheep, grizzly bears, and wolves, which will contribute to the revision of grizzly and Dall's sheep management plan; 2) understand the interactions between those species; 3) evaluate the effect of habitat features and climate on those interactions; and 4) document traditional knowledge about Dall's sheep, g...


ArcticNet Theme 1: Integrated Regional Impact Study of the Coastal Western Canadian Arctic
Principal Investigator: Fortier, Martin
Licenced Year(s): 2013 2012 2011 2010 2009 2007 2006 2005 2004
Summary: Warming of the Arctic is resulting in changes in sea ice formation, decay, and distribution which operate differently in the Eastern and Western Canadian Arctic. Short term sampling has been conducted, but this research is a long-term observation of the ocean, sea ice, atmosphere coupling. Sampling will be conducted at mooring stations, along the ship track, and at specific sampling stations, ...


Biocomplexity of frost-boil ecosystems
Principal Investigator: Walker, Donald A
Licenced Year(s): 2006 2005 2004 2003
Summary: The goal of this project is to understand the complex linkages between biogeochemical cycles, vegetation, disturbance and climate across the full summer temperature gradient in the Arctic in order to better predict ecosystem responses to changing climate...


Climate forcing factors and the record of climatic variability in the western Canadian Arctic during the past 2000 years
Principal Investigator: Tomkins, Jessica
Licenced Year(s): 2006 2005
Summary: The idea of the study is that researchers use the layers of sediment in a lake-bottom to figure out what the climate was like every year from last year to 2000 years ago. The researchers want to 1) look at cores of lake-bottom sediment that show layers...


Climate Geochemistry
Principal Investigator: Guo, Laodong
Licenced Year(s): 2005 2004
Summary: The purpose of this study is to collect river waters to determine the concentrations of dissolved organic carbon, particulate organic carbon, and nutrients, including nitrate, phosphate and silicate, and to examine their temporary variations related to c...


Constraints To Ecosystem Development in High Arctic Polar Deserts
Principal Investigator: Bliss, Lawrence
Licenced Year(s): 1994
Summary: We seek to better understand how ecosystems develop in the high arctic following retreat of ice caps. This includes studies of soil development and the influence that rocks play in this as well as studying the development of block crusts of organisms that form on the soil surface. We will also try to understand the role these crusts play in fixing nitrogen and influencing the development of flower...
