2017 Baseline monitoring of marine productivity and oceanography spanning the Northwest Passage using ships of opportunity
Principal Investigator: Fisher, Jonathan AD
Licenced Year(s): 2017 2016
Summary: The first objective is to collect, analyze and report the findings from station-based and continuous plankton sampling and data on depth, temperature and salinity in the upper water column throughout Canada’s Northwest Passage. As a contribution to marine climate change research, this program will provide northern communities with the first regional-scale view of marine productivity—thereby provid...


Structure, Carbon Dynamics, and Silvichronology of Boreal Forests
Principal Investigator: Osawa, Akira
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001
Summary: The objectives of the research are two-fold. First is to estimate structure, growth, and production of forest stands in northwestern Canada by applying a stand reconstruction and 3D ground-based laser techniques as well as stand measurement, aboveground litter collection, and find root sampling. Second is to examine the relationship between climate change in the high latitudinal regions and the pa...


Effects of Climate Change and Landscape Perturbation on Arctic Tundra Lake Water Quality
Principal Investigator: Droppo, Ian G
Licenced Year(s): 2017
Summary: The overall goal of this study is to obtain information, through laboratory experiments (rainfall simulator; 2m annular flume) on sediments collected from retrogressive permafrost thaw shoreline slumps affecting numerous Arctic tundra lakes in the Mackenzie Upland Region east of the Mackenzie Delta, on the physical processes through which slump material is transported and delivered to a receiving ...


Glacial lakes McConnell and Mackenzie reconstructed from Pleistocene deltas of the Mackenzie River tributaries
Principal Investigator: Froese, Duane G
Licenced Year(s): 2017 2016
Summary: The objective of this project is to investigate the architecture of Pleistocene deltas on the Mackenzie River tributaries, search evidence of high-magnitude discharge events, and collect samples for absolute dating. The research team will investigate the stratigraphic description of sedimentary sections in the river banks cutting through the Pleistocene deltas. Collection of samples are for rad...


EL494 Surface Water Monitoring Program 2016-2018
Principal Investigator: von Kuster, Jenica
Licenced Year(s): 2017 2016
Summary: The study is to continue to establish natural variations in the surface water conditions within the Exploration Licence (EL 494) area and monitor potential impact of oil and gas exploration activities. Surface Water Quality Sample Collection: Collect surface water samples once, during August 2017, from a reduced number of sampling locations targeted near areas where exploration activities have...


Neoproterozoic stratigraphy, Mackenzie Mountains
Principal Investigator: Turner, Elizabeth C
Licenced Year(s): 2017
Summary: This continuing research addresses the history of Earth-surface environments between about 1 billion and 700 million years ago. The objective for 2017 is to complete the sample suite being used by a PhD student (most of the required samples are already in-hand). A base-camp of two people will be deployed by helicopter, and all work done on foot. Working on mountainside rock exposures, the resea...


Community-based long-term monitoring of the Peel River near Fort McPherson
Principal Investigator: Moore, Jonathan
Licenced Year(s): 2017
Summary: The objective of this project is to establish a community-based monitoring program in the Peel River watershed, based in Fort McPherson. Previous research has shown that multiple whitefish ecotypes (non-anadromous, semi-anadromous and anadromous), utilize the Peel River as spawning habitat, but it is unclear how much each ecotype contributes to harvester catches. As different ecotypes occupy d...


Long-term reconstructions of cold-season climate and atmospheric Hg deposition from ice wedges in the Mackenzie Delta region
Principal Investigator: Porter, Trevor
Licenced Year(s): 2017
Summary: This purpose of this research is to better understand long-term changes in winter temperatures and atmospheric mercury (Hg) in the Mackenzie Delta area over the last 11,700 years, a period known as the Holocene. The fieldwork aims to sample 20-30 ice wedges that represent a range of Holocene time. Precipitation stable hydrogen isotopes (a temperature proxy) and elemental Hg archived in the wedge i...


Akaitcho - DUC Wetland Mapping Project
Principal Investigator: Richard, Alain
Licenced Year(s): 2017
Summary: The main objective of this project is to develop wetland inventory for south eastern Northwest Territories (NWT) that will be used to provide a baseline for many kinds of planning (including land use planning processes) and research in support of biodiversity conservation and sustainable management of habitat. Specific objectives are to: 1) develop and use computer-based methods to produce we...


NATCL Cantung 2017 EEM Program
Principal Investigator: Carson, Richard J
Licenced Year(s): 2017 2015
Summary: The objectives are to evaluate if there are differences in biological parameters among study sites and between years at the Tungsten Mine site; as well as to determine whether observed differences from the most recent (2015) Environmental Effects Monitoring study are still present and whether any differences are the result of mining practices. The study objectives are to evaluate fish health, ...
