Principal Investigator:Grogan, Paul Licenced Year(s):
The long-term goal of my research over the next 15-20 years is to substantially advance the understanding of how Canadian arctic tundra ecosystems function, and therefore how they are likely to be affected by these perturbations.
This research will work to answer the following questions:
1) Apart from birch, which other species within the mesic tundra plant community also have their growth c...
Principal Investigator:Pumpanen, Jukka S Licenced Year(s):
The aim of the ARCTICFIRE project is to study the long term effects of natural forest fires on the decomposition of soil organic matter in the northern arctic and subarctic forests. The research team will study the changes in size and quality of soil carbon and nitrogen pools and fluxes after forest fires and their underlying processes in the arctic and subarctic zone, especially the interactions ...
Principal Investigator:Blowes, David Licenced Year(s):
This research study is designed to investigate the processes related to water quality and quantity (collected at different scales) draining from country rock stockpiles that are located in areas of continuous permafrost. The quality of water draining from a country rock stockpile is determined by the combined effects of oxygen transport in the air phase, biogeochemical processes that control miner...

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...
Principal Investigator:Lesack, Lance Licenced Year(s):201620152014
The goals of this research are to examine: 1) measurements of water depths and lake depths for selected area of the Mackenzie Delta; 2) changes in lake flooding and historical lake boundaries in the Mackenzie Delta.
Specific activities for this field season include the following:
(1) Improved information on the detailed topography of the Mackenzie Delta floodplain and how delta water levels a...

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...
Principal Investigator:Marschner, Mark Licenced Year(s):
This study aims to better understand the formation of "calcrete" deposits, using field samples from the Campbell Uplift. Field sampling will be carried out daily using ground transportation to and from a base in Inuvik. Initial activities will include...
Principal Investigator:Reimer, K.J. Licenced Year(s):
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 Licenced Year(s):
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...
Principal Investigator:Marsh, Philip Licenced Year(s):1993
This long term study is being conducted to assist in understanding the factors controlling water levels and the availability of nutrients in a variety of lakes in the Mackenzie Delta....
