Sub-sea temperatures and a simple tentative model for offshore permafrost at Prudhoe Bay, Alaska
Arthur H. Lachenbruch, B. Vaughn Marshall
1977, Open-File Report 77-395
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...
Carborne radiometric survey of the Nome area, Seward Peninsula, Alaska
Robert A. Brooks, Warren Irvin Finch
1977, Open-File Report 77-472
A carborne radiometric survey was made along the accessible roads in the Nome, Alaska, area. The background radiation was generally found to be low, about 40 cps, but higher radioactivity near granite was noted. No radioactive anomalies of a magnitude greater than three times the average background were encountered....
Channel erosion surveys along the TAPS route, Alaska, 1977

1977, Open-File Report 78-611
Channel surveys were made along the trans-Alaska pipeline system (TAPS) route during 1977 at the same 28 sites that were studied in 1976. In addition, a new site at pipeline mile 22 near Deadhorse (alignment No 134) along the Sagavanirktok River was put under surveillance. Except for changes wrought by...
Chemical composition of Precambrian, Paleozoic, Mesozoic and Tertiary rocks from east-central Alaska

The purpose of this report is to make available 108 analyses of a variety of igneous, sedimentary, and metamorphic rocks from east-central Alaska. The rocks were collected by the senior author, Michael Churkin, Jr., G. Donald Eberlein, Reuben J. Ross, Jr., and James Melik from 1960 to 1963....
Surface sedimentary units of the Gulf of Alaska continental shelf: Montague Island to Yakutat Bay
Bruce F. Molnia
1977, Open-File Report 77-30
Four major sedimentary units occur on the sea floor of the continental shelf in the northern Gulf of Alaska. These units, defined on the basis of seismic and sedimentologic data, are: (1) Holocene sediments, (2) Holocene mind moraines, C3) Quaternary glacial marine sediments, and (4) Tertiary and Pleistocene lithified deposits. A...
Geologic framework of lower Cook Inlet, Alaska
Michael A. Fisher, Leslie B. Magoon
1977, Open-File Report 77-136
Lower Cook Inlet is located in south-central Alaska between lat 58°45' and 60°30' N. and between long 151° and 154° W. (fig. 1). Geographic features on the perimeter of the area are the Aleutian Range on the northwest, Kalgin Island on the northeast, the Kenai Peninsula on the east, the...
Aquatic organisms from selected sites along the Trans-Alaska Pipeline corridor, September 1970 to September 1972: supplement
Jon W. Nauman, Donald R. Kernodle
1977, Open-File Report 77-634
This report is a supplement to earlier preconstruction studies of benthic invertebrates and water quality at selected sites along the trans-Alaska pipeline corridor. Some of the problems which arose during the course of data collection and analysis are discussed. Benthic invertebrate abundance and community-structure data are presented for 20 sites...

Bathymetric and shoreline changes, northwestern Prudhoe Bay, Alaska
Peter W. Barnes, Erk Reimnitz, Greg Smith, John Melchior
1977, Open-File Report 77-161
The coastal environment in the vicinity of Prudhoe Bay, Alaska (Fig. 1) is presently being vigorously utilized by petroleum activities. In particular, barges moving freight onshore over the past 8 years, have used the Prudhoe Bay entrance channel almost exclusively. To further facilitate the offloading of supply barges, Atlantic Richfield...

Genesis of a zoned granite stock, Seward Peninsula, Alaska
Travis Hudson
1977, Open-File Report 77-35
A composite epizonal stock of biotite granite has intruded a diverse assemblage of metamorphic rocks in the Serpentine Hot Springs area of north-central Seward Peninsula, Alaska. The metamorphic rocks include amphibolite-facies orthogneiss and paragneiss, greenschist-facies fine-grained siliceous and graphitic metasediments, and a variety of carbonate rocks. Lithologic units within the...
