Temperature and oxygen concentrations in Dolomite (Airport) Lake
Principal Investigator: Lord, Sarah
Licenced Year(s): 2017
Summary: The purpose of this study is to directly measure temperature and dissolved oxygen concentrations in Airport Lake throughout the year, and to find out if low oxygen levels are limiting the growth rate of lake trout population in this lake. Repeated sampling at the same locations on the lake during fall, winter, spring, and summer will show whether oxygen levels are adequate for optimal lake trout t...


The ecology and paleoecology of benthic macroinvertebrates in the Mackenzie Delta region
Principal Investigator: Quinlan, Roberto
Licenced Year(s): 2017 2016 2015 2014 2013
Summary: The objectives of our study are to 1) establish the importance of lake connectivity in determining the community composition and species richness of the invertebrate community of a lake, and the contribution of lakes of differing connectivity to the regional diversity of the Mackenzie Delta, 2) characterize the response of invertebrate communities to changing peak flood levels to allow prediction ...


Under The Pole - Innovative Underwater Exploration
Principal Investigator: Bihan-Poudec, Anne-Claire
Licenced Year(s): 2017
Summary: This survey aims at discovering bioluminescent and biofluorescent species in Polar Regions (namely the Arctic), assessing and understanding the potential functions of the phenomena. Marcel Koken and his team hope to discover bioluminescent or biofluorescent species in the Arctic mesophotic zone. As the mission consists of an exploration of an under-studied part of the ocean, the scientific team...


Drivers of lichen diversity at different latitudes
Principal Investigator: Scharnagl, Klara
Licenced Year(s): 2017
Summary: The objectives at Scotty Creek in the Northwest Territories of Canada is to get a high latitudinal point for the field sampling study. Many latitudinal gradient studies overlook the boreal and tundra ecosystems, yet they are host to a rich lichen flora. The Principal Investigator (PI) will survey lichen diversity at Scotty Creek, contributing to local knowledge in addition to the understanding of ...


Global monograph of the Hymenogastraceae family
Principal Investigator: Davies, Linda L
Licenced Year(s): 2017
Summary: The objectives of this project are to study the diversity and distribution of the genus Hebeloma at the global level; and, to assemble a more complete phylogeny of Hebeloma and of the family Hymenogastraceae that will in turn further understanding of the evolution and development of characters in this family. The research team will survey local areas to look for basidiomes of the genus Hebeloma...


NTPC Bluefish Hydro Repairs
Principal Investigator: Panayi, Damian
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010
Summary: The objective is to describe the aquatic environment in the Yellowknife River between Bluefish Lake and Prosperous Lake as per the Fisheries Authorization and the Water Licence. This may include investigating aquatic vegetation, water quality and quantity, benthic invertebrates, fish and substrate. The results will be used to determine the most suitable means of fish habitat compensation or produc...


Environmental Baseline Surveys for the Fortune Minerals Limited NICO Project
Principal Investigator: Schryer, Richard P
Licenced Year(s): 2017 2016 2014 2013 2012 2011 2010 2009 2008 2006 2005 2004 2003
Summary: The objective of this project is to complete a Supplemental Baseline Monitoring Plan (SBMP) for water quality, fish population and benthic invertebrate programs. The SBMP contains two major study areas: Burke Lake, Reference Lake and the Marian River. Burke Lake will be the exposure area and Reference Lake will serve as the reference area for the SBMP. The exposure area for the Marian River wat...


Reclamation of Disturbed Sites Research at Diavik Diamond Mine, NWT
Principal Investigator: Naeth, M. Anne
Licenced Year(s): 2017 2016 2015 2014 2009 2008 2005
Summary: The overall research goal is to determine appropriate methods to restore disturbed sites at Diavik Diamond Mine to productive and sustainable tundra communities following mine closure. There are three main research areas 1) building suitable reclamation substrates for plant establishment and growth, 2) methods of collection and propagation of locally common native plant and lichen species, and 3) ...


Contemporary Dynamics of Forest-Tundra Ecotones in Central NWT
Principal Investigator: Danby, Ryan K
Licenced Year(s): 2016
Summary: Objectives of this research project are to: 1) analyze Landsat satellite images to understand regional vegetation change over the past 30 years; 2) determine the timing of tree establishment as well as the climate influence on tree growth across the forest tundra transition zone over the past 300 years; and, 3. measure spruce seedling growth across the forest-tundra ecotone in relation to varia...


Paulatuk Whitefish Assessment
Principal Investigator: Ruben, Diane
Licenced Year(s): 2017 2016
Summary: The objectives of the research are to conduct an assessment of whitefish diet and contaminants. Two technicians will collect approximately 60 samples over 7 days at Billy’s Creek in July 2016 and an additional 60 samples at the Hornaday River in August and October 2016. Data will be collected on: species, location, date/time, catch-effort/gear type, length, weight, sex, maturity, otolith, stom...
