Using the past to inform the future: A paleoecological perspective of the impacts of drought and fire on lakes, permafrost and forests
Principal Investigator: Pisaric, Michael FJ
Licenced Year(s): 2017 2016
Summary: The objectives of this research are to examine the frequency and severity of past wildfire and drought (drought-like) conditions in the southern Northwest Territories. Specifically, the research team will examine the following questions: 1) how frequent and severe have fires been in the past; 2) are fires becoming more frequent/severe due to the impacts of climate change; 3) what impact does wildf...


Pliocene environmental change on Prince Patrick Island
Principal Investigator: Gosse, John
Licenced Year(s): 2016
Summary: Our main goals of this research project are: 1.) to collect sediment samples that will be used to provide ages of the sediment in the Beaufort Formation on Prince Patrick Island; and, 2.) to collect samples of fossil material (wood, plants, bone) that can be analyzed to produce climate reconstructions for the Pliocene. The research team will travel to approximately 5-6 site locations. The t...


The microfossil record of the Cambrian explosion
Principal Investigator: Smith, Martin R
Licenced Year(s): 2016
Summary: The objectives of this research project are to measure continuous sedimentary sections spanning Proterozoic-Phanerozoic transition; to use geochemical approaches to precisely constrain the age and depositional conditions of the strata; and, to obtain Small Carbonaceous Fossils and Small Shelly Fossils from temporally-constrained strata in order to determine the rate of evolution through the Cambri...


A novel, exceptionally preserved, shark fauna from the Early Carboniferous of the NWT
Principal Investigator: Dearden, Richard P
Licenced Year(s): 2016
Summary: The research team will visit the site, as specialists in vertebrate palaeontology, in the hope of finding more of these well-preserved cartilaginous fishes. This will hopefully result in more fossil material, which will be collected and taken back to the institutions for study. The work would involve searching for more fossils: this mainly consists of hiking over the rocky exposures above the t...


Vertebrates of the Ancient Arctic Seas: Palaeontology of the Late Cretaceous Anderson River Formation, northern Northwest Territories, Canada
Principal Investigator: Vavrek, Matthew J
Licenced Year(s): 2016
Summary: The research team will be travelling to the Anderson River via helicopter, approximately 220 km due west of Inuvik. The team will be camping in a small fly camp while in the field. Two weeks will be spent in the field, searching the exposed rocks along the banks of the Anderson River for fossils of extinct marine vertebrates. All work will be done on foot. Any fossils that are found are important ...


Liard Basin 2012 - Golata Formation Fossil
Principal Investigator: Fiess, Kathryn
Licenced Year(s): 2014 2013
Summary: To identify a vertebrate fossil of Carboniferous age recently found in the Golata Formation in the Liard Basin. The research group is studying outcrops of Devonian to Carboniferous age shale to establish the hydrocarbon resource potential for the NWT, BC, and Yukon regions of the Liard area. Scientific investigations include measuring rock outcrop sections and taking small (approximately 100 ...


The ecology and paleoecology of benthic macroinvertebrates in the Mackenzie Delta region
Principal Investigator: Quinlan, Roberto
Licenced Year(s): 2016 2015 2014 2013
Summary: This study will examine the effects of permafrost and flooding on the ecological structure and carbon exchange of contrasting lakes in the Mackenzie River Delta. Patterned ground marked by ice-wedge polygons is formed by freezing and thawing of the soil, which forms cracks into which ice can spread and cause the soil to uplift. These processes have effects on the hydrology and water chemistry of a...


Hay River vertebrate fossil recovery
Principal Investigator: Henderson, Donald M
Licenced Year(s): 2013
Summary: The objectives of this research project are to: 1) excavation of the body fossil(s) and their careful packaging for removal and travel; and 2) make latex rubber peels of the fossilized trackways left on a fine-grained limestone. If the quality of the tracks merits it, the rock slabs hosting the tracks may be removed for safe-keeping and public display. The fossil will be collected using standar...


Late Cretaceous Palaeontology of northwestern Northwest Territories, Canada
Principal Investigator: Vavrek, Matthew J
Licenced Year(s): 2013
Summary: This project is a continuation of the collaborative research program on ancient biodiversity in the Canadian Arctic. Recently, the group completed work supported by Polar Continental Shelf Project in the Brackett Basin in the westcentral Northwest Territories and the Bonnet Plume Basin in northeastern the Yukon Territory, during which the research team recovered both new vertebrate (dinosaur) foss...


Testing the northern route for Younger Dryas meltwater
Principal Investigator: Keigwin, Lloyd D
Licenced Year(s): 2013
Summary: Here is the project summary from the (U.S.) National Science Foundation proposal that led to this expedition: The research team propose a three-year project to investigate the origin of the Younger Dryas cooling that began about 13,000 years ago. For decades this cold event has been associated with sea ice in the Arctic and North Atlantic Oceans, and the storage and release of fresh water from ...
