Principal Investigator: Schunke, Ekkehard
Licensed Year(s): 2000 1994 1992 1990
Summary: The researcher will measure discharge, run-off velocity, sediment load, dissolved load and microclimate parameters (air and ground temperatures, relative humidity, evaporation, precipitation and radiation) in small valleys of James Creek. They drive to the location in a 3/4 ton truck which is parked in an abandoned quarry near the road. They walk to their data collection sites. The observations...

Principal Investigator: Wolfe, Stephen A
Licensed Year(s): 1999
Summary: The objective of the present study is to assess the impact of recent warming, including the warm summer of 1998, on active layer thicknesses and slope stability in the Mackenzie Delta, N.W.T. and Yukon North Slope. The main mode of transportation will be by helicopter (206L) and by boat to transport people. The helicopter will be based out of Inuvik with a fuel cache at Tuktoyaktuk. The helicop...

Principal Investigator: McGuinness, Michaella
Licensed Year(s): 1998
Summary: The objective of this study is to document and gain a better understanding of the processes that formed the karst (solution-controlled) landforms of the Campbell Dolomites. The data to be collected includes descriptive data such as slope angles and aspect, composition, size , type and angularity of slope material and detailed surveying of the land. Transportation to and from the base camp will be...

Principal Investigator: LAURIOL, Bernard
Licensed Year(s): 1998
Summary: The aim of the study of mass movements in the Richardson Mountains is to understand the processes of erosion related to climate changes. The site to be studied is located south of Little Fish Creek. The landscape looks like bench forms which are named Cryoplanation terrasses. This site was visited last year for 2-3 hours. Their formation are not really understood but we suspect that the melting of...

Summary: The Coastal Impacts project on the Beaufort Sea coast has two complementary objectives: 1. To improve our understanding of coastal processes; 2. To develop methods for prediction of coastal impacts of changing climate. Field work will be performed in the modern Mackenzie Delta, along the Tuktoyaktuk Peninsula coast, and at North Head if time permits. Collaborative field work in Ivva...

Principal Investigator: English, Michael C
Licensed Year(s): 2000 1996 1995
Summary: We will arrive at Fort Resolution on or about mid June and re-establish our base camp on Steamboat channel. For each day we are on the delta will be taking samples of sediment from the marshes of the outer delta area with a coring device. At the base camp we will take the core of sediment and section it into 2cm thick sections which will be air dried and shipped south for analysis....

Principal Investigator: Perks, Matthew
Licensed Year(s): 1996 1995
Summary: The researchers will achieve detailed mapping of granite- metasediment contacts by relying on detailed documentation of mineral asseblages, textures, metamorphic grade, and relative timing of the meta-sedimentary and meta-igneous rocks in the MacNaughton Lake area. Isotope U-Pb studies of granite and metasediment minerals will be used to constrain the absolute timing of intrusion and metamorphism....

Principal Investigator: Hill, Philip R.
Licensed Year(s): 1994 1993 1992
Summary: The researchers will examine the rate of coastal change in the outer Mackenzie Delta region in order to understand the factors contributing to present delta formation and coastal erosion, and to understand how global climate warming may affect coastal change. Surveys on beaches, sand bars and delta lakes will be conducted....

Principal Investigator: Pearce, Cheryl M.
Licensed Year(s): 1993 1992 1991 1990
Summary: The researcher will continue her long-term study on the physical features of the Mackenzie Delta. Hydrocarbon development, water volume and course changes, and climate change could have major effects on the water and sedimentation patterns of the delta. This study will increase knowledge of sedimentation patterns, shoreline erosion and their relationships with vegetation....

Principal Investigator: Blasco, Steve M
Licensed Year(s): 1990
Summary: The amphibious vehicle will be mounted with an echosounder, sidescan sonar, subbottom and seismic profiling equipment to run a test survey along the coast of the Tuktoyaktuk Peninsula. The CCGS NAHIDIK will tow a sidescan sonar system over the seafloor to rerun track lines surveyed in previous years to allow for the detection and measurement of the characteristics of new scours on the seafloor of ...
