Summary: This proposal aims to constrain the timing, magnitude, and spatial heterogeneity of erosion that lead to development of the Great Unconformity (GU) to test hypotheses for oxygenation and the Cambrian explosion. The GU is one of the most geologically significant and largest temporal gaps in the rock record, marking the boundary between Precambrian and Phanerozoic time. It has been proposed that ero...

Summary: The wind abraided rocks 3 km south of Paulatuk are among the best examples of ventifacts in North America. The rocks have smooth, lichen-free surfaces on their south side, which are blasted by sand and snow during strong southerly winds in winter. The re...

Summary: This project involves monitoring changes in the coast and refining estimates of land uplift or subsidence using passive geodetic and survey measurements at sites throughout the western Arctic, supported by existing data on coastal submergence and emergence from geological observations. Long-term coastal change under existing climate and sea-level trends will be determined at reference sites of th...

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: 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: 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 ...

Principal Investigator: Watts, Stephen
Licensed Year(s): 1988
Summary: Dr. Watts will be collecting samples of rocks while he is investigating how weather and glaciers cause bedrock to erode....
