Summary: This licence has been issued for the scientific research application No.4640. The research team is 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 bu...

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 ...

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 ...

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...

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...

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...

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...

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...

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...

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...
