Detailed study of the rhyolite dome and surrounding volcanic rocks at Sunset Lake, Slave craton, Northwest Territories
Principal Investigator: DeWolfe, Michelle
Licensed Year(s): 2019
Summary: This research is focused on increasing the understanding of the geological history of the Sunset Lake area through a detailed examination of ancient volcanic rocks exposed in this area. This work will be conducted mostly by hiking on foot. Zodiac boat with 25hp outboard motor or canoe will be used to reach the start of the hike each day. The hikes will be no more than 2 km from the lakeshore. D...


A 2,000 year record of climate change from white spruce tree-rings
Principal Investigator: Porter, Trevor
Licensed Year(s): 2019
Summary: This fieldwork aims to collect ‘disk’ samples from dead trees found on the surface or partially buried in sediments. Previous research in the Campbell Dolomite Upland area reported deadwood samples dating back to AD 1060. This area is well-drained, which is the ideal environment for preserving deadwood over long periods. The research team will return to this area to search for older specimens dati...


Cambrian stratigraphy and paleontology
Principal Investigator: Pratt, Brian R.
Licensed Year(s): 2019
Summary: Sedimentary rocks of Cambrian age (~500 million years old) are the oldest Phanerozoic strata in the Mackenzie River valley region and record the spread of a shallow sea over much older strata. The approximate age of these rocks is known via trilobite fossils based on reconnaissance collections made in the 1960s and 2010s. The purpose of the project is to make more closely spaced fossil collections...


Kennady North Diamond Project
Principal Investigator: Panayi, Damian
Licensed Year(s): 2019 2018 2017 2016
Summary: The objective of this project is to document existing environmental conditions, in preparation for future regulatory applications Various environmental studies will be initiated each year, according to budgets and information priorities. Hydrology studies include the measurement of selected lake inflow and outflow and stream profile through field surveys, and installation of data loggers to ...


Where on Earth is fire-derived carbon stored?
Principal Investigator: Abiven, Samuel
Licensed Year(s): 2019
Summary: The objective is to measure the age and stock of organic carbon derived from wildfires (fire-derived carbon) in the Mackenzie River region, and examine long- and short-term processes controlling the size and distribution of fire-derived carbon stocks in soils. The research team will measure fire-derived carbon stocks in soils and determine its age (radiocarbon dating) at four different location...


Neoproterozoic stratigraphy, Mackenzie Mountains II
Principal Investigator: Turner, Elizabeth C
Licensed Year(s): 2019
Summary: The objective of this research is to addresses the history of Earth-surface environments between 1 billion and 700 million years ago. The objective for 2019 is to complete a sample suite used by a Master of Science student. Each base-camp of 2 people will be deployed by helicopter, and after that, all work will be done on foot, with no motorised equipment. Working on mountainside exposures, the...


Large wood transport in the Mackenzie River Basin
Principal Investigator: Sendrowski, Alicia
Licensed Year(s): 2019
Summary: The objectives of this project are to understand the dynamics of large wood transport in the Mackenzie River and Delta by identifying the locations of wood sources and deposition, and quantifying the amount of wood that reaches the delta and the processes affecting wood transport. Using this knowledge, the research team can make estimates of carbon transport to the Arctic and improve global models...


Devonian reference section, sourcerocks and paleomagnetic study
Principal Investigator: Kabanov, Pavel
Licensed Year(s): 2019
Summary: To acquire a reference geologic section of Devonian strata in the area of relatively easy access and with the preservation of rocks allowing for comprehensive study of Devonian-time Earth and hydrocarbon potential of the Canol shale play. The research team will be conducting field measurement and photo-documentation of the available section, survey of the measured section with spectral gamma-ra...


North central Slave craton bedrock mapping
Principal Investigator: Knox, Bernadette
Licensed Year(s): 2019
Summary: The objectives of this project is to update and increase the understanding of the geological history of this area of the north-central Slave craton, Northwest Territories. This work will be conducted mostly by foot with access along the water provided by canoe and zodiac boat. The research team will be walking the land to make geological maps. The team will note observations of the rocks includ...


Permafrost carbon fluxes
Principal Investigator: Pumpanen, Jukka S
Licensed Year(s): 2019
Summary: The field work in Trail Valley Creek and Inuvik aims to study: 1) how catchment characteristics, such as vegetation and soil properties, control the amount and quality of aquatic dissolved organic matter (DOM) and its microbial degradability, and 2) how these factors further regulate greenhouse gas fluxes (carbon dioxide CO2, methane CH4, nitrous oxide N2O) from Arctic lakes. At the Dempster hi...
