UpTempO: Measuring the Upper Ocean Temperature of the Arctic Ocean
Principal Investigator: Steele, Michael
Licensed Year(s): 2013 2011 2010
Summary: The central logistics hypothesis is that a crucial component of an Arctic Observing Network is ocean thermistor string buoys that are capable of measuring the local, atmospherically warmed upper 60 m of the Arctic Ocean. The focus is on the increasingly open seas of the Canadian and eastern Eurasian Basins. The central scientific hypothesis that provides motivation for this proposal is that the...

Effect of spring and summer temperatures on amphipod reproduction (Gammarus lacustris)
Principal Investigator: Messmer, David J
Licensed Year(s): 2012
Summary: To determine how spring and summer temperatures affect the abundance of the amphipod Gammarus lacustris throughout the summer. Over the 2 years of the experiment, the research team plans to use amphipods from 4 different sources over several latitudes (Montana-USA, St. Denis-SK, Yellowknife-NT, Inuvik, NT). Using this variety of geographic sources will allow us to assess if different populations...

Diavik Aquatic Effects Monitoring Program 2012
Principal Investigator: Moore, Kristin M
Licensed Year(s): 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2005 2004 2003 2002 2001
Summary: To revisit fixed sample stations at near-field, mid-field and far-field sites over the course of a year in an effort to determine any seasonal variation that may exist and confirm impact predictions. The study will encompass the following water based parameters: water quality, zooplankton & phytoplankton biomass and taxonomy, benthic invertebrate analysis and sediment chemistry. This program also ...

Influence of Mackenzie Delta Channel Thermal Regime on Permafrost
Principal Investigator: Ensom, Timothy P
Licensed Year(s): 2010 2009
Summary: The purpose of this research is to measure the seasonal temperatures of streambeds at several sites in the Mackenzie delta and adjacent tundra uplands, and predict the implications of these temperature patterns for local permafrost conditions. This project will seek to determine whether channel size and depth affect the annual thermal regime of the streambed, and will also use collected temperatu...

2009 Baseline Studies for Avalon Ventures Ltd. Proposed Thor Lake Rare Earth Metals Project – Groundwater Hydrology and Hydrogeology
Principal Investigator: Lennie-Misgeld, Peter
Licensed Year(s): 2009
Summary: The baseline study is being conducted to aid Avalon Ventures in assessing potential environmental effects of its activities and having adequate environmental information to support filing of regulatory applications in the future. Two years of data collection is important for obtaining baseline ground water hydrology and quality data where seasonal changes in groundwater levels, recharge and discha...

Spring Season Coastal Reseach in the Beaufort Region
Principal Investigator: Forbes, Donald L
Licensed Year(s): 2004
Summary: Safe and sustainable hydrocarbon development and potential impacts of climate change on coastal infrastructure and subsistence activities require improved knowledge and understanding of coastal and nearshore seabed properties, and coastal hazards such as...

2001 Baseline Slimy Sculpin/Lake Trout Habitat Utilization Studies
Principal Investigator: Madsen, Eric
Licensed Year(s): 2001 2000
Summary: The objective of this study is two fold: a) to collect slimy sculpin tissue samples for baseline metal analysis; b) to monitor seasonal lake trout habitat utilization in Lac de Gras using radio telemetry methodologies. Twenty-five Slimy sculpins will be collected using baited minnow traps and opportunistic underwater netting, using professional SCUBA divers if available. Samples will be sent to ap...

Peel River Fish Study
Principal Investigator: Walker-Larsen, Jennifer
Licensed Year(s): 2001
Summary: Community monitors will be hired to catch and sample fish from their camps. These camps will be accessed by boat and helicopter. Monitors will catch fish with an experimental gillnet, measure fish and remove aging structures. There will be no fish wasted-all fish will be kept and used by the monitors....

Active Layer Monitoring Network in the Mackenzie Valley
Principal Investigator: Nixon, Mark
Licensed Year(s): 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1991 1990
Summary: This season, a party of two will survey tubes between Tsiigehtchic and the coast during March and April and from Fort Simpson to the Arctic Coast in July and August. Staff of the Inuvik Research Centre may take late season measurements north and south of Inuvik as part of a cooperative program. Travel will be by road, small boat on the river and helicopter from Inuvik. Access to the sites is alw...

Environmental Baseline Program Colomac Area (Indin Lake), N.W.T.
Principal Investigator: Kalich, Laura
Licensed Year(s): 1996
Summary: The work will include seven aspects of research. Water quality will be done through a number of sampling locations at different times of the year. A hydrology study will measure high water discharge and stage measurements at seven streams in the vicinity of the proposed all-weather road. Bathymetric surveys will conducted on lex lake and six smaller un-named lakes in the vicinity of the propos...
