Résumé(Sommaire disponible en anglais seulement)
Dobrocky Seatech Ltd. was contracted by the Geological Survey of Canada to conduct a coastal zone data collection program at King Point on the Yukon coast of the Beaufort Sea. The project was funded by the Northern Oil and Gas Action Program ( NOGAP) , a research and planning program intended to anticipate research needs and management problems associated with Arctic hydrocarbon developments. King Point has been proposed as a site for port development, and information on the wind and wave climate, coastal geology and rates and directions of sediment transport is required. Data collected in this study are being used to provide input to coastal sediment transport model predictions for the King Point area. A remote tent camp was established at King Point and occupied from August 24 ta September 16, 1985. Field operations were conducted with rudimentary logistics support equipment and involved extensive use of SCUBA diving to deploy and recover equipment. The King Point barrier beach, lagoon and nearshore areas were surveyed extensively using theodolite, level and echo sounding techniques. Sediment samples were also collected from the active beach and nearshore areas. A recording Aanderaa weather station was established to measure wind speed, direction and barometric pressure. Coastal currents were measured with five Aanderaa current meters deployed at 5, 7.5, 10, 12.5 and 15 m depths. The current meters were equipped with wave zone rotors. Wave characteristics were measured with two Sea Data directional wave and current meters deployed at 5. 6 and 2. 7 m depths. The shallowest wave meter was located within 20 m of the steeply sloping sand and gravel beach and measured nearshore wind and wave generated currents. Approximately daily measurements and observations were also made of the beach face environment and samples of suspended sediment were collected to coincide with nearshore current recordings.
