A monitoring program for Frame Lake
Principal Investigator: Gray, Derek K
Licensed Year(s): 2019
Summary: We are planning to establish a long-term monitoring program in Frame Lake to monitor water quality, zooplankton, and benthic Invertebrates. Water quality probes will be set up at a central monitoring point on the lake. A buoy will be anchored to the lake bottom and the probes will be attached to the buoy. The probes will monitor temperature, dissolved oxygen, pH, and conductivity levels near th...


Biological responses to multiple environmental stressors in lakes around Yellowknife, NT
Principal Investigator: Smol, John P
Licensed Year(s): 2019
Summary: The main goal is to understand the spatial distribution of phytoplankton and zooplankton species in lakes around the Yellowknife area and provide environmental context to the ongoing paleolimnological (reconstructing the environmental histories of lakes) investigations. This year, the research team aim to collect phytoplankton and zooplankton from a suite of lakes around Yellowknife following ...


Climate change impacts on lake ecosystems of the western Canadian Arctic
Principal Investigator: Korosi, Jennifer B
Licensed Year(s): 2019
Summary: The objectives of this research is to: 1) determine if thaw slumping results in the loss of a large-bodied zooplankton species (Daphnia) from lakes; and 2) measure polychlorinated biphenyl concentrations in lake sediments near the Distant Early Warning Line site in Tuktoyaktuk, to assess whether legacy contamination is still evident. The research team will be collecting sediment cores from ...


Identification of hybrid copepods between C. finmarchicus and C. glacialis
Principal Investigator: Maps, Frederic FM
Licensed Year(s): 2018
Summary: Project aims to identify hybrid between C. finmarchicus and C. glacialis and to estimate the geographical distribution of the hybrids. Sample will be collected from a ring net, mesh size 200 micrometer (µm). The net will be deployed from the back of the boat. It will be towed vertically at a speed of 30 m/min. The samples collected will be sieve through 200 µm stainless steel mesh to separate w...


Further Examination of the Bio- Magnification of Mercury within Fish Species of the Deh Cho and their Varying Levels among Lakes
Principal Investigator: Swanson, Heidi
Licensed Year(s): 2018 2017 2016 2016 2015 2014 2013
Summary: The objectives of this research project are: 1) to determine why fish mercury levels vary among lakes in the Dehcho region; 2) to identify best predictors of fish mercury levels; and, 3) to determine with fish have the lowest levels of mercury and the highest levels of nutrients. The methods for this project include field sampling, laboratory analysis, and data analysis and reporting. The resea...


A Coastal, Pan-Canadian Collection of Plants, Microalgae, and Marine Invertebrates for the Canadian Museum of Nature
Principal Investigator: Graham, Mark S
Licensed Year(s): 2017
Summary: The goal of this work is to assemble a representative collection of marine invertebrates, vascular plants, lichens, mosses, liverworts and aquatic, microscopic algae for research and educational purposes at the national museum (the Canadian Museum of Nature). Specimens will be used in ongoing research projects at the Canadian Museum of Nature, focused on the biodiversity of the vascular plant, lic...


Predicting climate-driven changes in water quality and biological communities in Gwich'in lakes
Principal Investigator: Gray, Derek K
Licensed Year(s): 2017
Summary: Zooplankton play a key role in aquatic food webs, providing a conduit for the movement of energy between primary producers (algae) and larger organisms such as macroinvertebrates and fish. Therefore, elucidating the impact of permafrost melting on zooplankton is key to gaining a broader understanding of climate change on aquatic ecosystems in Canada’s north. Objectives of this proposed researc...


ArcticNet: an Integrated Regional Impact Study of the Coastal Western Canadian Arctic.
Principal Investigator: Fortier, Martin
Licensed 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 regio...


Aquatic Effects Monitoring Program 2008
Principal Investigator: MacDonald, Gord
Licensed Year(s): 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2005 2004 2003 2002 2001
Summary: The objective of this study is to determine any seasonal variation in water quality, zooplankton & phytoplankton biomass and taxonomy, benthic invertebrate analysis and sediment chemistry, and will also include dust monitoring. Transportation will be by boat, snow machine, and helicopter. Samples will be taken for water chemistry, phosphorous & nitrogen, sediment, benthic invertebrates, zoopla...


Biogeochemistry of Lakes in the Mackenzie Delta
Principal Investigator: Lesack, Lance
Licensed Year(s): 2017 2016 2015 2014 2010 2009 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Summary: The long-term goal of this project is to develop a biogeochemical model for lakes in the Mackenzie Delta, and ultimately, a more general ecosystem model for floodplains and deltas of major world rivers that will help assess the effects of multiple stresses on rivers resulting from global change. Numerous major river deltas in the Arctic circumpolar region are lake-rich because of thermokarst effec...
