Reconstructing history of hummocky soil formation in drunken forest
Principal Investigator: Fujii, Kazumichi
Licenced Year(s): 2017
Summary: “Drunken forest” is developed on earth hummocks on shallow permafrost layer near Inuvik, Canada. Black spruce forests are typically grown on the shoulder of mounds and tree rings record the history of soil movement. By reading tree rings, the Principal Investigator (PI) will reconstruct history of hummocky soil formation. The PI will collect tree core samples by making hole in wood of black sp...


Predicting climate-driven changes in water quality and biological communities in Gwich'in lakes
Principal Investigator: Gray, Derek K
Licenced 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...


Slave Province Surficial Geology and Permafrost Study
Principal Investigator: Elliott, Barrett R
Licenced Year(s): 2017 2015
Summary: The objectives of the research are to generate new surficial geology maps and surficial geological studies covering approximately 5 50k National Topographic System (NTS) sheets, to install an new permafrost monitoring network at the treeline transition as well as to generate case studies of using small soil samples to detect a buried kimberlite and using passive geophysics equipment (measures eart...


Thermal State of Permafrost
Principal Investigator: Siegfried, Dian
Licenced Year(s): 2016 2013 2010
Summary: The objective of this project is to continue an ongoing long-term monitoring of permafrost temperatures on Banks Island and Mould Bay. At these sites the research team have lost remote (satellite) communication and need to make repairs to continue receiving data. The research team are currently monitoring active layer and permafrost temperatures, active layer soil moisture, air temperature, and...


ARCTICFIRE
Principal Investigator: Pumpanen, Jukka S
Licenced Year(s): 2015
Summary: 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 ...


Ground ice - vegetation relationships in the North Slave region
Principal Investigator: Baltzer, Jennifer L
Licenced Year(s): 2015 2014
Summary: The primary objective is to quantify the relationships between vegetation community composition, structure and near-surface ground ice content. An improved understanding of ground ice-vegetation interactions allows a better understanding of permafrost ecosystems the ability to more easily measure near surface ground ice conditions. Around Yellowknife there is a patchwork of bedrock outcrops sep...


Biogeochemical variations in Pleistocene and Holocene-age permafrost across various ecological landscapes, western Canadian Arctic.
Principal Investigator: Lacelle, Denis
Licenced Year(s): 2014
Summary: The proposed project is a collaborative work between academic researchers, the NWT Geoscience Office and local communities. The objectives of the project are to: (1) investigate geochemical variations in the uppermost 3-5m of permafrost in the western Canadian Arctic; (2) assess potential geochemical implications of anticipated permafrost thaw on terrestrial and aquatic systems; (3) examine soil c...


Environmental soil chemistry at abandoned drilling mud-sumps in the Kendall Island Bird Sanctuary, Mackenzie Delta Region
Principal Investigator: Biggar, Kevin
Licenced Year(s): 2006 2005
Summary: Since the 1970's, the oil and gas industry has drilled at least 19 exploratory wells in the Kendall Island Bird Sanctuary (KIBS), but there is a shortage of field data describing environmental conditions at the well-sites and drilling-mud sumps. In Marc...
