Principal Investigator: Wild, Birgit
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No.5564. The main goal of the project is to understand how gradients in tundra vegetation and permafrost thaw affect soil carbon and mercury cycling. This will allow the research team to assess how permafrost thaw and changes in vegetation in a warmer climate could alter future carbon dioxide fluxes and impact mercury cycling ...

Summary: This licence has been issued for the scientific research application No.4938. The specific objectives of the project are as follows: 1) Determine the spatial extent, distribution, and timing of winter icing events in streams along the ITH through ground-based and aerial reconnaissance of stream crossings; 2) Identify relations between physical watershed characteristics and icing dynamics thro...

Summary: The overarching objective of the study is to integrate light detection and ranging (LiDAR), passive spectral, and tree ecophysiological data to link biophysical structure to ecological function in the Forest Tundra Ecotone. In so doing, the research team will be able to remotely assess the vulnerability and resilience of the forest tundra ecotone (FTE) to environmental change. The field work wi...

Summary: Zooplankton play a key role in aquatic food webs, providing a conduit for the movement of energy between primary producers (algae) and larger organisms such as macroinvertebrates and fish. Therefore, elucidating the impact of permafrost melting on zooplankton is key to gaining a broader understanding of climate change on aquatic ecosystems in Canada’s north. Objectives of this proposed researc...

Principal Investigator: Lantz, Trevor C.
Licensed Year(s): 2016 2015
Summary: The objectives of this research project are: 1) To use remote sensing to document the rate and extent of landscape change on Banks Island; 2) To examine the effects of tundra disturbances using detailed field investigations; and 3) Use participatory mapping and interviews to document Inuvialuit Knowledge of Landscape Change on Banks Island. In this project the research team are using remot...

Principal Investigator: Bhatti, Jagtar
Licensed Year(s): 2011 2010 2009 2008 2007
Summary: The objective of this research is to assess variations and processes controlling CO2, CH4 and N2O dynamics along the Mackenzie Valley, to investigate the amount and character of greenhouse gases released, and to understand conditions controlling soil GHG emissions. Soil gas sample tubes will be sampled on a seasonal basis for gas concentration (CH4, N2O, CO2) and isotope ratios. The response of...

Principal Investigator: Washington, John
Licensed Year(s): 2006
Summary: PFOA is a synthetic compound documented as being widely dispersed in the environment, including in biota of high-northern latitudes. The route of this dispersal is not entirely clear. PFOA concentrations in soil samples from several locations around the world will be analyzed to determine environmental reservoirs and global distribution. Two new 250-ml HDPE sample bottles will be shipped to Auro...

Principal Investigator: Biggar, Kevin
Licensed Year(s): 2006 2005
Summary: Since the 1970's, the oil and gas industry has drilled at least 19 exploratory wells in the Kendall Island Bird Sanctuary (KIBS), but there is a shortage of field data describing environmental conditions at the well-sites and drilling-mud sumps. In Marc...

Principal Investigator: Pyc, Cynthia
Licensed Year(s): 2004
Summary: Soil samples will be taken from four potential sump sites for the 2005 drilling program. Soil samples will provide information on active layer depth, soil composite, salinity levels, permeability and moisture content to determine sump site suitability. I...

Principal Investigator: Reimer, Kenneth J.
Licensed Year(s): 1997
Summary: The Environmental Services Group has been requested by Defence Construction Canada and DCLU, to continue conducting environmental investigations of former DEW Line sites. Personnel will collect soil, sediment, plant, water, paintchips and insulation samples from areas of suspected or known contamination. The samples will be analyzed for inorganic elements and PCB's. In addition a small-scale bio...
