Sub-sea temperatures and a simple tentative model for offshore permafrost at Prudhoe Bay, Alaska

In this report, we present temperatures measured in three holes drilled into the sea bed in the Prudhoe Bay region and a tentative interpretation of them in terms of the gross thermal regime and shoreline history of the area. The new holes (PB-1, PB-2, and PB-3, Figure 1) were drilled in spring, 1976 (see Sellmann, 1976) as part of a cooperative study of off-shore permafrost by the USGS, CRREL, and the University of Alaska. Results from two of the holes (#190 and #3370, Figure 1) drilled earlier by the University of Alaska (Osterkamp and Harrison, 1976) have been included in our interpretation. The reader not interested in analytical details may wish to examine Figures 1, 2, and 3, and then skip to the concluding section "Summary and Discussion," page 32.

Gazetteer of coastal and offshore features of the Gulf of Alaska north of 54° N latitude

This gazetteer, the first of three to be released, presents names of seafloor features of the Gulf of Alaska and coastal features north of 54° N latitude between Cross Sound to the east and Unimak Island to the west. Also included are Prince William Sound and Cook Inlet but not the fiords, channels, and shoreline of southeast Alaska that make up the "Inside Passage" and Alexander Archipelago.

U.S. Geological Survey offshore program of resource and geo-environmental studies and topical investigations, Pacific-Arctic region

The Geological Survey's marine geology investigations in the Pacific-Arctic area are presented in this report in the context of the underlying socio-economic problem of expanding the domestic production of oil and gas and other mineral and hard- and soft-rock resources while maintaining acceptable standards in the marine environment. The primary mission of the Survey 's Pacific-Arctic Branch of Marine Geology is to provide scientifically interpreted information about the (1) resource potential, (2) geo-environmental setting, and (3) overall geologic characteristics of the continental margins (that is, the continental shelf, slope and rise) and adjacent deeper water and shallower coastal areas off California, Oregon, Washington, Alaska and Hawaii and also, where it is of interest to the U.S. Government, more remote deep-sea areas of the Pacific-Arctic realm.

Progress in remote sensing as it applies to missions of Committee for Coordination of Joint Prospecting for Mineral Resources in Asian Offshore Areas

The major thrusts of investigations of the use of space data for understanding our Earth continue to focus on the land and near-shore environments. This is expectable; people live on the land, draw most of their resources from the land or near-shore areas, and in these areas environmental degradation or improvement are most clearly observable. An exception to this focus of investigation was the launch of Seasat, a satellite dedicated to marine investigations. Seasat was short lived but the data produced strongly supported the use of imaging radar for land investigation, and, although studies are incomplete, suggest eventual benefits for the navigator, searchers for marine resources, and mariners--provided that the data and/or interpretations can be available to the marine users shortly after collection. In this regard, the positive steps now being taken in Southeast Asia to establish reception, processing, and interpretation centers are a major development.
