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
chercheur principal:
Année(s) de permis: 1993 1992 1989 1988 1987
Résumé: 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...


Climate change and postglacial paleoenvironmental history of peatlands in the Mackenzie Delta area
chercheur principal:
Année(s) de permis: 1993 1992
Résumé: This research is part of an international project that is aimed at documenting the history of changes in the treeline during the Holocene era. While much is known about the environment and climate of this era, little is known about the development of peatlands during this time. I will collect data on peat layering, pollen and fossils in order to determine how the peatlands developed during this ...


A study of the supply of organic bromine from the ocean to the arctic atmosphere.
chercheur principal:
Année(s) de permis: 1993 1992
Résumé: Previous research has indicated that compounds containing bromine could play a role in the destruction of the ozone layer. This study is part of on-going research that is examining how important northern marine waters are as sources of bromine to the Arctic atmosphere. Seawater, snow and ice will be collected and assessed for bromine. In addition, measurements will be taken to determine if seaw...


Mackenzie Basin Impact Study: Land Assessment
chercheur principal:
Année(s) de permis: 1993 1992
Résumé: The Mackenzie Basin Impact Study will assess the potential impacts of global climatic change on the region. The component on land assessment will determine possible changes in land capability. Information on resource management goals is needed so that the study can can assess whether changes in land capability might lead to conflicts over land use....


Tuktoyaktuk Traditional Knowledge Project and Traditional Knowledge of Climate Change
chercheur principal:
Année(s) de permis: 1995 1994 1993 1992 1991
Résumé: The researcher and her team will document the early history of the reindeer herding industry, conduct interviews with elders to obtain information on the location and nature of traditionally used places and gain insights into aspects of traditional technology that are of benefit to archaeological interpretation. As well, traditional knowledge of climate change will be examined through interviews ...


Climatic Change at the Forest-Tundra Boundary
chercheur principal:
Année(s) de permis: 1992 1991 1990
Résumé: 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....
