Summary: This research will continue the long term objective of documenting and understanding the impacts of recent climate change on northern terrestrial and aquatic ecosystems. The short term objectives of my research for 2018 are: 1) to investigate the impacts of permafrost degradation and subsequent thaw slumping on freshwater ecosystems; 2) to examine the limnological implications of drained lakes on ...

Summary: The objectives of this research project are to: 1. map and assess changes in the distribution and composition of forest and peatland ecosystems due to climate changes; 2. estimate carbon storage (and variation) in boreal to arctic ecoregions of the Mackenzie valley; and 3. assess interannual and seasonal variations and key processes controlling carbon dioxide (CO2) and methane (CH4) dynamics. ...

Summary: The impact of climate change on forest ecosystems in the Mackenzie Delta is being studied using dendrochronology. Earlier studies indicate a negative relationship between tree growth and summer temperatures. Summer temperatures may be exceeding the physiological threshold of northern trees or perhaps the trees are drought stressed. Manual and automatic dendrometers will be used to measure tree gro...

Summary: The active layer, overlying the permafrost layer, is the surface earth material that thaws and re-freezes each year. Active layer thickness and character can influence hunting, fishing, forestry, gardening, transportation and construction. Changes in the active layer can contribute to landslides which may damage structures, hamper transportation, affect water quality, and influence surface and sub...

Summary: The purpose of this study is to collect river waters to determine the concentrations of dissolved organic carbon, particulate organic carbon, and nutrients, including nitrate, phosphate and silicate, and to examine their temporary variations related to c...

Summary: This research is concerned with the nature and style of glaciation as well as sea level changes and past climatic changes. The broad objective of the research is to obtain a long term paleoclimatic record (before the arrival of the Pre-Dorset people) fro...

Principal Investigator: Douglas, Marianne
Licensed Year(s): 2002 2000 1999
Summary: The overall goal of the research is to more fully understand the present-day water quality of arctic lakes and ponds, and to attempt to determine if the water quality of these sites are changing as a result of, for example, recent climatic change or othe...

Summary: This project investigates the the distribution and amount of near-surface ice in sediments of the Mackenzie delta area near Inuvik. Sites near Inuvik will be accessed via road and sampled using a hand held power auger. Soil cores will be removed and taken to the Inuvik Research Center for subsequent examination. The thickness of permafrost will be measured by near-surface water jet drilling which ...

Licensed Year(s): 1993 1992 1991
Summary: This long-term, ongoing study is aimed at understanding the factors controlling water levels and the availability of nutrients in a variety of lakes in the Mackenzie Delta. This work will allow us to better understand the natural Mackenzie Delta ecosystem, and to make better predictions of the effect of environmental change on the Delta. Cores of sediment will be collected from lake bottoms to d...

Summary: The researcher and his team will investigate the range of potential impacts of changing global climate on the coastline of the Canadian Beaufort Sea. This will be done by a combination of monitoring and site investigations to ascertain processes and process rates affecting coastal responses to present day environmental forcing....
