Northern Native Seed Development Field Trials
Principal Investigator: Trimble, Annika EV
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2007 2006
Summary: The objective of this sub-project are: 1) to continue assessing the performance of native plants which were seeded and transplanted into field plots in 2006 and 2007. 2) to establish two new field plots at the Inuvik golf course with the same intent of monitoring native seed performance in a disturbed habitat. The research team intend to collect data regarding winter survival, seedling emerg...


Structure, Carbon Dynamics, and Silvichronology of Boreal Forests
Principal Investigator: Osawa, Akira
Licenced Year(s): 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001
Summary: Objectives of the field work are two-fold: one is to collect data in jack pine and in lesser extent black spruce forests on annual movement of organic matter and carbon; the other is to continue the study of stand development and its relationship to environmental factors (a discipline called ‘silvichronology’). For the former objective, the research team will continue measurement of the growth of ...


Remote Sensing of Arctic Vegetation Biochemistry
Principal Investigator: Kennedy, Blair E
Licenced Year(s): 2014 2013
Summary: The objectives of the research are: (1) measure the spectral properties (i.e. how light is absorbed and reflected) and biochemical constituents (e.g. chlorophyll, water, nitrogen, carbon) of arctic vegetation at the ground-level in various vegetation communities across the Western Arctic (e.g. low-arctic to high-arctic); (2) investigate the potential of using satellite based multi-angular imaging ...


Quantifying carbon fluxes and budgets of boreal forest-tundra landscapes under the influence of rapidly changing permafrost regimes
Principal Investigator: Sonnentag, Oliver
Licenced Year(s): 2017 2016 2015 2014 2013
Summary: Through this project the research team will address the following objectives: What is the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system? How do these two types of feedback differ between the discontinuous and continuous permafrost zones? Is the reported decrease (increase) in net CO2 (CH4) exchange based on plot- (<1m2) and ecosystem-scale ...


Carbon Cycling Linkages of Permafrost Systems [CYCLOPS]
Principal Investigator: Williams, Mathew
Licenced Year(s): 2014 2013 2012
Summary: The ultimate aim of the proposed project is to develop and evaluate a detailed process-based model of vegetation-soil-permafrost interactions using data collected through directed field campaigns in the discontinuous and sporadic permafrost zones of western Canada. The research team will (i) elucidate the role of plant biodiversity in controlling permafrost status in contrasting ecosystems with di...


Ecological Assessment Field Work for Lue Túé Sulái (the Five Fish Lakes) Candidate Cultural Conservation Area
Principal Investigator: Haas, Claudia A
Licenced Year(s): 2012 2011
Summary: This project is to fill gaps in ecological information on a Candidate Protected Area while it makes its way through the NWT Protected Areas Strategy (PAS) process. This information will be used by the working group to make recommendations on final boundary and management planning for the area. The study will be done at the same time as a study on mercury in fish being conducted by the Dehcho F...


Improving Habitat Connectivity to Enhance Productive Capacity of Arctic Freshwater Ecosystems
Principal Investigator: Tonn, William
Licenced Year(s): 2014 2013 2012 2011 2010 2009
Summary: The objectives of this project are 1) to study the freshwater ecology, hydrology, and hydraulics of small lakes and streams in the Lac de Gras basin before habitat modification; 2) to monitor the changes in ecosystem productive capacity resulting from habitat modifications designed to increase habitat connectivity and fish passage; and 3) to assess the effectiveness of such habitat modifications t...


7 Mine Site Project
Principal Investigator: Widmeyer, Joline
Licenced Year(s): 2010
Summary: The objective of this study is to identify what fish species are in Ruth Lake and Bullmoose Lake and to conduct tissue sampling which will assist in determining if the fish in these lakes are bioaccumulating heavy metals. Fish will be sampled using techniques such as minnow trapping, seining, gill netting, angling and possibly boat electrofishing. Nets and minnow traps may be left at the sam...


ArcticNet: an 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: The central aim of the ArcticNet marine-based research program is to study on a long-term basis how climate induced changes are impacting the marine ecosystem, contaminant transport, biogeochemical fluxes, and exchange processes across the ocean-sea ice-atmosphere interface in the Canadian Arctic Ocean. Ultimately, the knowledge generated from this multi-year program will be integrated into region...


Recent changes in carbon source-sink relationships and greenhouse gas emissions in forest and peatland ecosystems along the Mackenzie Valley region of Canada
Principal Investigator: Bhatti, Jagtar
Licenced 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...
