2021 Summary:
This licence has been issued for the scientific research application No.5224.
The first objective of this project is to quantify microplastic concentration and composition in water, sediment, zooplankton, and air around Great Slave Lake. The second objective of this project is to examine if microplastic concentrations are greater near communities than the open water of Great Slave Lake. The thi...

2019 Summary:
This licence has been issued for the scientific research application No.4623.
The overall objective of this study is improved understanding of heavy metals in Sewage Disposal Facilities (SDFs) and Solid Waste Disposal Facilities (SWDFs) in the NWT. The proposed study aims to answer the following questions: 1) What is the existing treatment capacity of SDFs in NWT for heavy metals?; 2) Are SDFs ...

2018 Summary:
The goals of this research are to ascertain the formation of marine pockmarks, which are circular depressions on the sea floor thought to have formed from the release of methane gas. The hypothesis is that these features are actively releasing gas to the atmosphere and that they are formed from degrading or thawing offshore permafrost.
The research team intend to document the seabed characteris...

20182017 Summary:
The primary objective is to provide the means to improve the knowledge of physical conditions in the Arctic coastal zone in order to help government agencies, corporations and local residents understand mitigate and reduce the impacts of climate driven changes. This research has 3 targeted objectives: 1) to gain a better understanding of coastal permafrost; 2) to provide and updated assessment of ...

Summary:
The research team will investigate sections of exposed sediments along the Redstone River banks and some minor tributaries to establish the provenance and composition of these sediments. The team will evaluate the possible presence of ancient preglacial sediments buried beneath glacial sediments. It is also believed that ancient lake sediment may be present outside of the present flood plains of t...

Summary:
The objectives of this research project are:
1) to determine the impact of shoreline expansion and forest/peat submergence from thawing permafrost on contaminant and carbon fluxes to lakes in the Yellowknife region;
2) to develop novel approaches to track terrestrial organic matter sources in lakes, in order to assess how climate warming and permafrost thaw are affecting the delivery of terrestr...

Summary:
The objective of this research project is to assess the sediment quality of Baker Creek. This will be achieved by analyzing factors influencing arsenic mobility from sediments to overlying water and assessing the toxicology of the sediments using exposure tests on indicator organisms.
Core samples of Baker Creek sediments will be taken by the researchers using aluminum pipes driven into the gro...

Summary:
This study will investigate the quality of aquatic sediment and evaluate its potential as an indicator of ecosystem health in the Coppermine River basin. Sediment cores will be collected by boat or float plane at Lac de Gras and Point Lake. The following field measurements will be recorded: water temperature and pH, and sediment colour, texture and pH. In addition, personal interviews will be c...

Summary:
The main objective of the proposed research is to establish the origin of massive bodies of underground ice at two key massive-ice localities in the Mackenzie Delta area: i) Cliff Point, Liverpool Bay and (ii) near Eskimo Lakes. The research will be carried out by an interdisciplinary team of scientists examining the geology, glaciology and chemistry of the ice and adjacent sediments. The research...
