Drivers and constraints of ecological change in the western Arctic
Principal Investigator: Lantz, Trevor C.
Licensed Year(s): 2022 2021 2019 2018 2017
Summary: This licence has been issued for the scientific research application No.5277. The objectives of this research are: 1) Use remote sensing (Landsat, QuickBird, InSAR, Airphotos, UAVs, etc.) to document regional landscape change (tundra fire, infrastructure, saline flooding, slumps, subsidence, vegetation change, lake drainage / expansion, etc.); and 2) Use field sampling and monitoring to determi...


Snow Accumulation/Runoff in High Latitude Permafrost Basins
Principal Investigator: Marsh, Philip
Licensed Year(s): 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1990
Summary: The primary objective of this project is to develop improved understanding of the fluxes of water and energy in northern regions, and to develop improved computer models of these processes. The Trail Valley Creek site will be accessed by helicopter and s...


Active layer monitoring network in the Mackenzie Valley
Principal Investigator: Nixon, Mark
Licensed Year(s): 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1991 1990
Summary: This season, a party of two will survey tubes between North Richards Island and Tsiigehtchic during April and from Fort Simpson to the Arctic Coast in July and August. Travel will be by road, small boat on the river and helicopter from Norman Wells and Tutoyaktuk. Access to the sites is always on foot. This year is the seventh annual survey of a network of thaw depth measuring devices (thaw tub...


Long-term forest-tundra disturbance research
Principal Investigator: Wein, Ross
Licensed Year(s): 1993 1992 1989 1988 1987
Summary: In previous research in the 1970's, experiments and surveys provided information on the recovery rates of vegetation in response to disturbances from human activities. Several predictions about the long-term recovery of vegetation were made at that time. We are now collecting data to determine if these predictions reflect what is actually occurring. This information provides information about l...


Fire Severity and Growth of Treeline Tree Species: Climate Change Implications
Principal Investigator: Olsen, Sue K.
Licensed Year(s): 1992
Summary: The experiment will determine the interacting effects of fire severity, soil moisture and air temperature treatments on the emergence, winter survival and initial growth of treeline and near treeline tree species. The availability and viability of tree seed for successful regeneration of the treeline and near-treeline tree species will also be determined....


Climatic Change at the Forest-Tundra Boundary
Principal Investigator: Landhaeusser, Simon M.
Licensed Year(s): 1992 1991 1990
Summary: To determine the maximum size of treeline tree species in a burned and unburned valley in the Caribou Hills, the mass of standing trees on different slopes and aspects will be estimated and related to the energy input. In 1992 the plots prepared in 1990 and planted and seeded in 1991, will be revisited and measurement of growth for the second growing season will be taken....
