Design And Construction

The planning, design and construction of two offshore exploratory drilling islands, constructed in the Alaskan Beaufort Sea during the summer of 1980, is described. Emphasis is given to areas of the work that are either unique to the Alaskan Beaufort Sea or involve modifications to the artificial island technology developed in the Canadian Beaufort Sea. The construction of the islands using a land gravel source, transport and handling of the gravel by highly efficient equipment, and placement of the gravel using the limited marine equipment available at Prudhoe Bay is described. The development of an economical slope protection system, with a design life of 3 yr, in Arctic environment and the monitoring and maintenance program planned to minimize the propagation of anticipated damage and maximize the effectiveness of the slope protection system is described, and knowledge gained to date is also included.

Prudhoe Bay

The Prudhoe Bay Causeway is a gravel-fill structure that extends 4 km into the Beaufort Sea at Prudhoe Bay, Alaska. Concern over the impact of this structure on the marine Arctic environment prompted regulatory agencies to require owners of the causeway to sponsor a multidisciplinary monitoring program that encompasses the physical and biological realms of possible impact. This paper describes how such concerns are being addressed and also includes results of the initial studies of possible environmental impact of the causeway.

The recruitment of age 0+ Arctic cisco (Coregonus autumnalis) from Canada into the Prudhoe Bay, Alaska, area for the period 1981–88 was compared with summer wind data collected at Barter Island, Alaska. Four years of poor recruitment (1981, 1982, 1984, and 1988) were characterized by winds with net easterly components [Formula: see text] for the period 1 July—15 August. Four years in which moderate to strong recruitment occurred (1983, 1985, 1986, and 1987) were characterized by winds with net easterly components [Formula: see text]. Results suggest that the recruitment of young-of-the-year Arctic cisco from Canada to central Alaska is strongly influenced by wind-driven currents along the Beaufort Sea coast. Recruitment may be impaired by the absence of "strong" east winds without the actual presence of prevailing west winds.
