The export of terrigenous dissolved organic carbon from boreal terrestrial ecosystems to the Arctic Ocean and its vulnerability to environmental change
chercheur principal: Fichot, Cedric
Année(s) de permis: 2024 2023 2022
Résumé: This licence has been issued for the scientific research application No. 5611. The primary objective of this funded project is to develop a sophisticated model that can simulate the mobilization, transport, transformations, and export of terrigenous dissolved organic carbon (tDOC) from the Mackenzie River watershed to the Arctic Ocean. The model will be used to simulate the transfer of tDOC dur...


Beaufort Sea Coastal and Nearshore Geoscience Research 2018
chercheur principal: Whalen, Dustin JR
Année(s) de permis: 2019 2018 2017
Résumé: The primary objective is to provide the means to improve the knowledge of physical conditions in the Arctic coastal zone in order to help government agencies, corporations and local residents understand mitigate and reduce the impacts of climate driven changes.

Petrology and geochemistry of the late Archaean banded iron formation and associated turbidites, western Slave Craton: constraints on palaeoenvironment
chercheur principal: Haugaard, Rasmus RH
Année(s) de permis: 2013 2012
Résumé: The recent discovery of new occurrences of 2.9 - 2.6 Ga old banded iron formations in the NWT have opened an exceptional opportunity to study ocean chemistry directly preceding the Great Oxidation Event (GOE). In this regard, the research group has been engaged with the Northwest Territories Geoscience Office (NTGO) to undertake field and laboratory studies of Achaean Banded Iron Formation (BIF) f...


Neo-proterozoic glacial events, Mackenzie Mountains northwestern Canada
chercheur principal: Narbonne, Guy
Année(s) de permis: 2001 1999 1998 1996 1994 1992 1991 1989 1988
Résumé: This study looks at aspects of the earth's history. The Ice Brook Formation in the Mackenzie Mountains and the Sheepbed formation are rock units that will be studied. Members of the field party will be transported to base camps by helicopter and camp moves will be done by helicopter. Ground work is to be done on foot. Data is collected through photography of rock outcrops, measurement of stratigra...


Carbonate sedimentation in the Mesoproterozoic Bylot Supergroup (Baffin Island, N.W.T.) and its influence on microbialite microstructure.
chercheur principal: Kah, Linda
Année(s) de permis: 1994 1993
Résumé: Stromatolites are variously shaped mounds or reefs composed of sediments and the fossilized remains of single-celled marine organisms called blue-green algae. There are massive fossil reefs located on Baffin Island which are some of the largest known of their age. By studying the structure, form and chemical make-up of these reefs, information about the ancient ocean and the growth of ancient re...
