Principal Investigator: Langer, Moritz
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5833. This research aims to describe permafrost conditions and assess environmental risk at several drilling waste sumps in the Mackenzie Delta region, NWT. The objectives of this project are: 1) Assess the vulnerability of drilling mud sumps in the Mackenzie Delta region under varying site conditions and different clim...

Summary: This licence has been issued for the scientific research application No. 5841. The overall objective of this project is to determine the impact of changing land-ocean matter fluxes and coastal subsea permafrost on nearshore ecosystems and biodiversity in the Beaufort Sea. To reveal the trajectory of coastal habitats, it is critical to (1) determine how fluvial and coastal fluxes from the land...

Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5751. The project aims to directly observe seasonally strongly variable organic carbon concentrations and chemistry of the Mackenzie River and thus its fluxes to Arctic coastal waters. We aim for weekly observations of Mackenzie River biogeochemistry resolving the major phases of the hydrological year (winter under-ice flo...

Summary: This licence has been issued for the scientific research application No.5542. The proposed project aims to directly observe seasonally strongly variable organic carbon concentrations and chemistry of the Mackenzie River and thus its fluxes to Arctic coastal waters. The research team aim for weekly observations of Mackenzie River biogeochemistry during a period covering the major phases of the h...

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...

Licensed Year(s): 2011 2009 2007
Summary: Although the widespread permafrost soils in the Arctic rim have the ability to retain terrestrial organic carbon for many millennia, evidence indicates that the recent global warming trend may potentially lead to rapid permafrost destabilization and abrupt release of carbon stored in this vast reservoir. To assess whether this process is underway, and to evaluate its impact on biogeochemical proce...

Summary: The long term goal of this research is to develop a biogeochemical model for lakes in the Mackenzie Delta and a model for assessing the effects of stresses on rivers resulting from global change. This is year 13 of a 20 year program. Specific goals for this field season include: 1) investigating the sources and fates of dissolved organic carbon (DOC) in aquatic food webs of the Mackenzie Delta; 2)...

Principal Investigator: Reimer, K.J.
Licensed Year(s): 1994 1993
Summary: The researchers will collect soil/sediment, water, plant and other biological samples to investigate small-scale variations of introduced substances; to examine larger variations in tundra and marine ecosystems; and to aid decision-makers in identifying when and where remedial measures can be most effectively applied. This investigation will be conducted on abandoned DEW Line sites to evaluate th...

Principal Investigator: Swyripa, Murray
Licensed Year(s): 1993
Summary: Northward flowing rivers are thought to be major ways in which contaminants are introduced to the Arctic Ocean. As part of an on-going study, river water and sediments will be collected over the course of the year and assessed for the presence of contaminants. A total of 12 rivers in the Canadian arctic mainland will be sampled in this study, including the Mackenzie, Coppermine, Burnside, Ellice...
