  • Southcentral Alaska Stock
    Revised: April 2014 NORTHERN SEA OTTER (Enhydra lutris kenyoni): Southcentral Alaska Stock STOCK DEFINITION AND GEOGRAPHIC RANGE Sea otters occur in nearshore coastal waters of the U.S. along the North Pacific Rim from the Aleutian Islands to California. The species is most commonly observed within the 40-meter (approximately 12.2 feet [ft]) depth contour because the animals require frequent access to benthic foraging habitat in subtidal and intertidal zones (Reidman and Estes 1990). Sea otters are not migratory and generally do not disperse over long distances, although movements of tens of kilometers (km) (tens of miles [mi]) are common (Garshelis and Garshelis 1984). Annual home range sizes of adult sea otters are relatively small, with male territories ranging from 4 to 11 square kilometers (km2) (approximately 10.5 to 28.5 square miles[mi2]) and adult female home ranges from a few to 24 km2 (approximately 62 mi2) (Garshelis and Garshelis 1984; Ralls et al. 1988; Jameson 1989). Due to their benthic foraging, sea otter distribution is largely limited by their ability to dive to the sea floor (Bodkin et al. 2004). 1 Figure 1. Approximate distribution and stock boundaries of northern sea otters in Alaska waters (shaded area). The spatial scale at which sea otter populations are managed remains an important, although largely unexplored issue (Bodkin and Ballachey 2010) deserving further study. Bodkin and Ballachey (2010) used models of sea otter mortality to show that range-wide reductions and extirpations during the commercial fur trade of the 18th and 19th centuries occurred not simply because of excessive harvest, but because the harvest was not allocated proportional to the abundance and distribution of sea otters.

User population by tribal health organization are listed at the beginning of the service area chapters. Native People of Alaska. The Eskimos. More than half of all Alaska Natives are Eskimo. The two main Eskimo groups, Inupiat and Yupik, differ in their language and geography. The former live in the north and northwest parts of Alaska and speak Inupiaq; the latter live in southwest Alaska and speak Yupik. Few Eskimos can still speak their traditional Inupiaq or Yupik language as well as English. Along the northern coast of Alaska, Eskimos are hunters of the bowhead and beluga whales, walrus and seal. In northwest Alaska, Eskimos live along the rivers that flow into the area of Kotzebue Sound. Here, they rely less on sea mammals and more upon land animals and river fishing. Most southern Eskimos live along the rivers flowing into the Bering Sea and along the Bering Sea Coast from Norton Sound to the Bristol Bay region. The Aleuts. Most Aleuts originally lived in coastal villages from Kodiak to the farthest Aleutian Island of Attu.

This report describes, summarizes, and interprets all In the last three decades, the Mount Hayes quadrangle has known bedrock fossil and isotopic age studies for the Mount been the focus of many bedrock geologic studies. Bedrock Hayes quadrangle, eastern Alaska Range, Alaska. The geologic maps were published by Holmes (1965), Pewe and accompanying map shows the location of all known bedrock Holmes (1964), Rose (1965; 1966a, b; 1967), Rose and fossil and isotopic sample localities in the quadrangle on a Saunders (1965), Matteson (1973), Bond (1976), Stout (1976), generalized geologic base map. These fossil and isotopic age Richter and others (1977), and Nokleberg and others (1982). data are obtained from new studies, unpublished data of the U.S. The geologic base for this study is based partly on that Geological Survey, contributed unpublished data, and geology and to a greater degree on 1:63,360-scale geologic published data. This report is one result of a five-year mineral­ mapping of the entire quadrangle that was· done for the mineral resource assessment of the quadrangle that was done during the resource assessment study of the area (Nokleberg and others, summers of 1978 through 1982, with additional topical studies­ 1990).
