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.

Summer wind data collected at Barter Island, Alaska, were compared with commercial fishery catches of arctic cisco (Coregonus autumnalis) at the Colville River, Alaska, for the period 1967–85. There was a significant (p = 0.036) association between yearly catch-per-unit-effort and the percent of easterly winds after adjusting for a 5-yr differential in the two time series. Results suggest that young-of-the-year fish which spawn in Canada's Mackenzie River are aided in their westward dispersal into Alaskan waters via wind-driven longshore currents. The greater the prevalence of easterly winds (westerly currents), the greater the recruitment. Increased recruitment manifests itself as an increase in Alaskan commercial fishery catch some 5-yr later when fish have grown to a size that renders them susceptible to commercial nets.

AbstractIn June and July 1914 DiamondJenness.amember of Stefansson's Canadian Arctic Expedition 1913–18, excavated 103 archaeological features in three abandoned native villages originally inhabited 400 to 550 years ago on Barter Island and nearby Arey Island, northern Alaska. His notes, diagrams, and some 3300 specimens for long remained unstudied. Recently they have been shown to provide much of the available information on the prehistoric occupation of the western Beaufort Sea coast.

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.

AbstractThe fossil remains of 43 bowhead whales were mapped on the raised beaches of western Wollaston Peninsula, Victoria Island, Canadian Arctic, near the historic summer range limit of the Bering Sea stock in the Beaufort Sea. The elevations and radiocarbon ages of the remains demonstrate that the bowhead ranged commonly into the region following the submergence of Bering Strait at ca. 10,000 14C yr B.P. until ca. 8500 14C yr B.P. During the same interval, bowheads ranged widely from the Beaufort Sea to Baffin Bay. Subsequently, no whales reached Wollaston Peninsula until ca. 1500 14C yr B.P. Late Holocene populations evidently were small, or occupations were brief, in comparison to those of the early Holocene. Although the late Holocene recurrence may relate to the expansion of pioneering Thule whalers eastward from Alaska, there are few Thule sites and limited evidence of Thule whaling in the area surveyed to support this suggestion.
