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...

Long-term Ecological and Geomorphological Investigations in the Alpine Tundra of the Mackenzie Mountains, NWT
Principal Investigator: Kershaw, G. Peter
Licensed Year(s): 2018 2017 2016 2015 2014 2012 2010 2009 2008 2007 2006 2005 2004 2003
Summary: The main study objectives are to: 1) determine the status of permafrost landforms in the study area between Macmillan Pass and Plains of Abraham; and 2) determine the long-term recovery after abandonment of the CANOL No. 1 project. This is part of long-...

Derivation and Analysis of Climatic Information from Tree Rings
Principal Investigator: Jacoby, Gordon C.
Licensed Year(s): 1994 1989
Summary: The researcher will take 5 mm diameter increment core samples from old-aged trees growing near the tree line. This sampling is not harmful to the trees. At two sites the researcher will sample about 10 trees. The samples are processed to produce ring-width and wood- density data for each annual ring. This data will then be statistically compared to meteorological data to make estimates of past cl...

Global Change GSC Project 521-8847
Principal Investigator: Luckman, B.H.
Licensed Year(s): 1989
Summary: Dr. Luckman and one assistant will look for potential sites for the Geological Survey of Canada to study global change. They will also obtain recent tree-ring chronologies from treeline sites in the Mackenzie Delta....
