Winter Flow Regime and Icing Dynamics of Tundra Streams near the Inuvik to Tuktoyaktuk Highway
Principal Investigator: Ensom, Timothy P
Licenced Year(s): 2017
Summary: The objectives of the project are to: 1) determine the spatial extent, distribution, and timing of winter icing events in streams along the Inuvik to Tuktoyaktuk Highway (ITH) through groundbased and aerial reconnaissance of stream crossings; 2) identify relations between physical watershed characteristics and icing dynamics through field observations and analyses of watercourse and catchment mo...


Forest Ecotone Experiment
Principal Investigator: Eitel, Jan
Licenced Year(s): 2017
Summary: The overarching objective of this 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 w...


2017 Tarsuit Caissons Removal Program
Principal Investigator: Clarke, Kim P
Licenced Year(s): 2017
Summary: The objective of this project is to refloat and remove the Tarsuit Caissons from Lease Area 117/D11-3-7. Following their removal, the research team will conduct the following evaluation of the affected site and adjacent area: 1) Side Scan Survey 2) Macro invertebrate Survey A sidescan/multibeam unit (Edgetech 6205, or similar) will be pole mounted on the bathymetry vessel and data will be col...


Long-term perspectives on aquatic ecosystem change with thawing permafrost
Principal Investigator: Korosi, Jennifer B
Licenced Year(s): 2017
Summary: The research team will re-survey 70 lakes originally sampled in 2005/06, to assess how conditions have changed in the intervening decade as thaw slumping has intensified and the Inuvik-Tuktoyaktuk Highway (ITH) was constructed. The team will assess how lake ecosystems responded to past climatic shifts throughout the post-glacial history of these lakes (10,000 years), and use these records to provi...


NASA ABoVE Airborne Campaign
Principal Investigator: Miller, Charles E
Licenced Year(s): 2017
Summary: Preliminary flight lines have been planned with the goal of collecting data across a wide variety of ecosystems in both the US and Canada, with flights occurring from May – October 2017. The ultimate timing and flight paths would be dictated by weather and operational limitations at the time of flight, though deviations are expected to be minimal. A variety of aircraft and sensor suites will b...


Mackenzie Mountains bedrock mapping and stratigraphic studies
Principal Investigator: MacNaughton, Robert B.
Licenced Year(s): 2017
Summary: The objective of this research is to improve the public understanding of bedrock geology of two regions of the Mackenzie Mountains, including folding and faulting, stratigraphic relationships, tectonic history, and economic mineralogy. This objective includes sharing geoscience information with all interested parties through the production and publication of bedrock geology maps and reports on the...


Kennady North Diamond Project
Principal Investigator: Panayi, Damian
Licenced Year(s): 2017 2016
Summary: The objective of this research is to document existing environmental conditions surrounding the Kennady North Diamond Project. Hydrology studies include the measurement of selected lake inflow and outflow and stream profile through field surveys, and installation of data loggers to continually monitor lake levels through the open-water season. Hydrology studies will be initiated during the spri...


Permafrost and climate change, western Arctic Canada
Principal Investigator: Burn, Chris R
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998
Summary: The objective of this research is to understand the rate of ground warming in permafrost due to climate change and to measure the changes in ground surface characteristics that are occurring as a result. In particular, the research team are interested in changes in ground temperature, in the depth of the active layer, and in subsidence of the ground. The research team are also interested in measur...


Beaufort Sea Coastal and Nearshore Geoscience Research 2017
Principal Investigator: Whalen, Dustin JR
Licenced Year(s): 2017
Summary: The objective of this project is to provide the means to improve the knowledge of physical conditions in the Arctic coastal zone in order to help government agencies, corporations and local residents understand mitigate and reduce the impacts of climate driven changes. Field surveys will be undertaken in consultation with Hunters and Trappers Committees (HTCs) in order to ensure the timing of ...


Polar Airborne Measurements and Arctic Regional Climate Model Simulation Project (PAMARCMIP)
Principal Investigator: Herber, Andreas
Licenced Year(s): 2017
Summary: The observational platform will be a single aircraft, the Alfred Wegener Institute (AWI) POLAR 5, a modified DC-3 aircraft. Objectives of this project are to: 1. determine the actual state of the sea ice thickness distribution in the western Arctic and what are trends of the Sea Ice thinning; 2. characterize the actual sea ice thickness distribution and identify trends in the sea ice thickne...
