The effect of a fuel oil spill on benthic invertebrates and water quality on the Alaskan arctic slope, Happy Valley Creek near Sagwon, Alaska
Jon W. Nauman, Donald R. Kernodle
1975, Journal of Research of the U.S. Geological Survey (3) 495-500
Samples of aquatic organisms and water were collected upstream and downstream from leaks and spills of arctic diesel fuel oil into Happy Valley Creek near Sagwon, Alaska. All groups of benthic invertebrates were reduced in abundance at the downstream boundary of the spill area, whereas invertebrates at an upstream site...
Geologic setting and chemical characteristics of hot springs in west-central Alaska
Thomas Miller, Ivan Barnes, William Wallace Patton Jr.
1975, Journal of Research of the U.S. Geological Survey (3) 149-162
Numerous hot springs occur in a variety of geologic provinces in west-central Alaska. Granitic plutons are common to all the provinces, and the hot springs are spatially associated with the contacts of these plutons. Of 23 hot springs whose bedrock geology is known, all are within 4.8 km (3 mi)...
Channel erosion surveys along southern segment of the TAPS route, Alaska, 1972 and 1973
Joseph M. Childers
1975, Report
This report presents descriptions of preconstruction conditions at selected stream-channel sites along the southern segments of the Trans-Alaska Pipeline System from Flood Creek to Valdez. The information presented can be used in studies of severe channel erosion streambed scour, bank erosion, or rechannelization. The report also presents a plan for...
Channel erosion surveys along TAPS route, Alaska, 1974
Joseph Childers, Stanley H. Jones
1975, Report
Repeated site surveys and aerial photographs at 26 stream crossings along the trans-Alaska pipeline system (TAPS) route during the period 1969-74 provide chronologie records of channel changes that predate pipeline-related construction at the sites. The 1974 surveys and photographs show some of the channel changes wrought by construction of the...
Water-quality changes during a salmon run in an interior Alaskan stream
Jon W. Nauman, Donald R. Kernodle
1975, Journal of Research of the U.S. Geological Survey (3) 103-106
Increased activity at sunset of sockeye (red) salmon (Oncorhynchus nerka) in an Alaskan stream resulted in increases in carbon dioxide, turbidity, suspended chlorophyll a, and drift invertebrates, and a decrease in pH and dissolved oxygen....
Mineral resource models and the Alaskan Mineral Resource Assessment Program
Donald A. Singer
W. A. Vogely, editor(s)
1975, Book chapter, Mineral materials modeling A state-of-the-art review
The least exacting demand that can be made of any model is that it serves as a device whereby we can predict actual physical happenings. Another demand which could be made is that the physical happenings predicted be in some way relevant to man, either by allowing him to anticipate...
Mercury distribution in ancient and modern sediment of northeastern Bering Sea
C.H. Nelson, D.E. Pierce, Kam Leong, F.F.H. Wang
1975, Marine Geology (18) 91-104
Reconnaissance sampling of surface and subsurface sediment to a maximum depth of 80 m below the sea floor shows that typical values of 0.03 p.p.m. and anomalies of 0.2-1.3 p.p.m. mercury have been present in northeastern Bering Sea since Early Pliocene time. Values are highest in modern beach (maximum 1.3...
An Anvilian (early pleistocene) marine fauna from western Seward Peninsula, Alaska
D.M. Hopkins, R.W. Rowland, R.E. Echols, P. C. Valentine
1974, Quaternary Research (4) 441-470
Cover sediments of the York Terrace exposed near the California River, western Seward Peninsula, Alaska, yield mollusks, ostracodes, and foraminifera that lived during the Anvilian transgression of early Pleistocene age. The fossiliferous sediments lie at the inner edge of the York Terrace, a...
Geology and ground water for land-use planning in the Eagle River-Chugiak area, Alaska
Chester Zenone, Henry R. Schmoll, Ernest Dobrovolny
1974, Open-File Report 74-57
The Eagle River — Chugiak area is a rapidly growing residential part of the Greater Anchorage Area Borough, south-central Alaska. High-density, urban development in some parts of the area may be restricted because of the nature of the surficial geologic materials and their hydrologic characteristics. This report assembles all information...
Water-quality and geohydrologic data at two sanitary landfill sites near Anchorage, Alaska
Chester Zenone, D.E. Donaldson
1974, Open-File Report 74-1131
Water-quality and geohydrologic data were collected at two sanitary landfill (solid-waste disposal) sites near Anchorage, Alaska. The study was undertaken by the U.S. Geological Survey in cooperation with the Greater Anchorage Area Borough and the U.S. Air Force. The purpose of the study was to evaluate the environmental effects of...
