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...


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 ...


Reconstructing Pliocene Environmental Change and Landscape Dynamics using the Beaufort Formation on Northwest Banks Island, NT
chercheur principal: Gosse, John C
Année(s) de permis: 2013
Résumé: The primary objectives are to i) collect fossils (i.e. peat, bone, wood, and other sedimentary proxies) for paleoenvironmental reconstructions and, ii) document the age of the Beaufort Formation (Fm) at Ballast Brook, northwest Banks Island using a new approach based on the exposure of quartz sand grains to cosmic radiation: terrestrial cosmogenic nuclide (TCN) burial dating. The cosmogenic nuclid...


The Search for Early Fossil Sharks in Lower Devonian rocks of the Mackenzie Mountains, NWT
chercheur principal: Wilson, Mark V.H.
Année(s) de permis: 2013 1998 1996 1990
Résumé: The 2 objectives of this research project are: 1) to recover some of the oldest-known body fossils of sharks and their relatives as well as other associated fossils. The anatomy of the fossil species will be described in detail and published in international journals. These fossils will allow identification of fragments of related species found at other sites worldwide, and will allow the researc...


Paleoecology of Mercy Bay Reefs, Frasnian, Banks Island, NWT
chercheur principal: Copper, Paul
Année(s) de permis: 2003
Résumé: The current study will re-examine the detailed structure, sedimentology, and paleoecology of the Devonian patch reefs of Mercy Bay, Banks Island, NWT. Transportation by fixed-wing aircraft to Polar Bear cabin near Castel Bay will be followed by helicopte...

Résumé: The current study will re-examine the detailed structure, sedimentology, and paleoecology of the Devonian patch reefs of Mercy Bay, Banks Island, NWT. Transportation by fixed-wing aircraft to Polar Bear cabin near Castel Bay will be followed by helicopte...


Biostratigraphy and sedimentology of Middle Cambrian deep-water deposits (Rockslide Formation), Mackenzie Mountains
chercheur principal: Pratt, Brian R.
Année(s) de permis: 2012 2002 2000 1998
Résumé: The researcher will study half a billion year old rocks in the Mackenzie Mountains, chartering a helicopter from Watson Lake to install and move light-weight camps and bring back samples. The strata of interest are exposed on mountain sides in remote are...


Paleoecology of Mercy Bay reefs, Frasnian, Banks Island
chercheur principal: Edinger, Evan N
Année(s) de permis: 2001 2000
Résumé: The research team will examine the detailed structure, sedimentology and paleoecology of reefs in Mercy Bay. Transportation by fixed-wing aircraft to Polar Bear cabin near Castel Bay will be followed by helicopter transport to various field sites (East Branch Mercy River; Lower Mercy River; Southern Patch reefs; Princess Royal Islands; Hay Point, Victoria Island; Gordon Point, Victoria Island). ...


Proterozoic Ice Ages in Northwestern Canada
chercheur principal: Narbonne, Guy
Année(s) de permis: 2001 1999 1998 1996 1994 1992 1991 1989 1988
Résumé: The research team will be flown from Norman Wells to the base camp near Shale Lake by helicopter. The camp will consist of one sleeping tent and one cooking tent. The research team will walk to several rock sections with 3 km of the base camp. Data collection will consist of measuring rocks with a ruler, taking photographs, and collecting up to 50 small (fist-sized) pieces with a hammer. The r...


Sedimentology, diagenesis and economic potential of Devonian sediments in the Franklinian Miogeosyncline on Bathurst Island
chercheur principal: Brand, Uwe
Année(s) de permis: 1993 1992
Résumé: The research will involve a detailed assessment of the make- up of Devonian rocks found on Bathurst, Helena, Cameron and Byam Martin Islands over a three-year period. The potential for oil, gas and/or mineral deposits in the Devonian strata will be assessed, but the major emphasis of the research will be on investigating the strata's geochemical, paleontological and sedimentological characteristi...
