The Nonacho Group Sedimentary Rocks
chercheur principal: Fischer, Beth J
Année(s) de permis: 2022
Résumé: This licence has been issued for the scientific research application No.5098. The research team would like to know the age of each formation of the Nonacho sedimentary rocks. Is the oldest formation a lot older than the youngest, or only a bit older? The team would like to know more about the sources of the Nonacho sediments. What types of bedrock were eroded to make those sediments? Did rivers...


Pliocene environmental change on Prince Patrick Island
chercheur principal: Gosse, John C
Année(s) de permis: 2017 2016
Résumé: 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...


Soil Carbon in the Mackenzie Delta Region
chercheur principal: Phillips, Marcus R
Année(s) de permis: 2015 2014 2013
Résumé: The goal of this research is to understand how landscape processes influence the quantity and quality of soil carbon in the Mackenzie Delta Region. Particular attention will be paid to the depth distribution of soil carbon and how it is affected by differences in vegetation and soil forming processes. Key environmental differences that will be examined include forest vs. tundra and delta vs. uplan...


Sampling of Quaternary glacial sediments exposed in Beaufort Sea and Amundsen Gulf area as a basis for comparison with marine sequences on Beaufort Shelf and Slope
chercheur principal: Dallimore, Scott R
Année(s) de permis: 2014
Résumé: This proposed research focuses on the collection of small sediment/pebble samples from known terrestrial glacial deposits at coastal exposures at various locations in the Inuvialuit Settlement Region (ISR). These sites each have different stratigraphic settings and existing published interpretations of glacial source and providence. The results from these investigations should enable direct c...


PWGSC Gordon Lake Environmental Site Assessments
chercheur principal: Nyman, Jeff
Année(s) de permis: 2013
Résumé: The objective of this program is to determine the environmental and physical conditions at nine sites on Gordon Lake. This will include the identification and quantification of environmental impacts in soil, sediment, surface water and groundwater, and the identification of any hazardous or non-hazardous materials. In addition, samples of biota (including vegetation, fish, benthic invertebrates) m...


Northwest Territories Power Corporation Twin Gorges Aquatic Effects Monitoring Plan and Sediment and Erosion Management Plan
chercheur principal: Byrne, Geraldine
Année(s) de permis: 2013
Résumé: The Aquatic Effects Monitoring Plan (AEMP) and Sediment and Erosion Management Plan (SEMP) are requirements under water license MV2011L0002 issued by the Mackenzie Valley Land and Water Board (MVLWB). The objective of the AEMP is to monitor and identify potential short-term, long-term and cumulative changes throughout the Taltson River aquatic environment. The objective of the SEMP is to identify...


Arctic Peatland Carbon and Holocene Warm Climates
chercheur principal: Beilman, David W
Année(s) de permis: 2013
Résumé: The research team seek to understand carbon dynamics during warm climate intervals in the Arctic: the Holocene Thermal Maximum (HTM) the warmest pre-industrial interval ranging in timing from 10 ka (thousands of years before present) with maximum seasonality to 6 ka with reduced seasonality, and the Medieval Climate Anomaly (MCA) at ~1 ka with similar seasonality as today. By studying peat cores f...


Beaufort Sea Coastal Geoscience Research 2013
chercheur principal: Whalen, Dustin JR
Année(s) de permis: 2016 2015 2014 2013 2012
Résumé: The primary objective of this research is to ensure safe and sustainable industrial and community development by improving the understanding of coastal and nearshore seabed processes and properties. The research provides the means to improve the knowledge of physical conditions in the coastal zone in order to help government agencies, corporations, and local residents understand, mitigate and redu...


Erosion of carbon from high-latitude peatlands: Isotopic insight into fluvial transfer in the Mackenzie River Basin
chercheur principal: Hilton, Robert G
Année(s) de permis: 2017 2013 2011 2010 2009
Résumé: The objectives of this research project are to correct for fossil particulate organic carbon (POC) input to the Mackenzie River, and to determine the loci of peatland organic carbon (OC) erosion and flux to the fluvial system. WATER VELOCITY TRANSECT At each sampling location, an Acoustic Doppler Current Profiler (ADCP) will allow the research team to determine bathymetry, water velocity trans...


Testing the northern route for Younger Dryas meltwater
chercheur principal: Keigwin, Lloyd D
Année(s) de permis: 2013
Résumé: 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 ...
