Description of seafloor sediment and preliminary geo-environmental report, Shelikof Strait, Alaska
Monty A. Hampton, K.H. Johnson, M.E. Torresan, W.J. Winters
1981, Open-File Report 81-1133
Shelikof Strait, situated between the Kodiak Island group and the Alaska Peninsula (Fig. 1), is included in OCS oil and gas lease area 60. Environmental geologic studies are being conducted by the U.S. Geological Survey prior to the scheduled September 1981 sale date. Seismic-reflection records, collected with 40- to 95-cm3...
Earthquake hazard studies in southeastern Missouri
William Stauder, Robert B. Herrmann, Brian J. Mitchell
1981, Open-File Report 81-888
This report is intended to be a compact review of the current "state of the art" of operating a seismic telemetry network as applied to the New Madrid area, and incidentally, to the Adak, Alaska network because of the author's position as technical director of that network under a joint...

Hard mineral resources around the U.S continental margin
Frank T. Manheim, H.D. Hess
1981, Conference Paper, Proceedings of the Annual Offshore Technology Conference
The territorial waters surrounding the United States contain vast quantities of hard mineral resources. Some, such as sand and gravel in the New York Bight, Beaufort Sea, portions of southern California, and submerged lands near Hawaii are relatively well known and characterized by local need and immediate mining potential with...
Earth flows along Henry Creek, northern Alaska
L. David Carter, John Galloway
1981, Arctic (34) 325-328
Many earth flows occurred during the summer of 1979 in the hilly terrain near Umiat, Alaska, particularly along Henry Creek. Most were shallow, involving only the tundra mat and no more than 1.5 m of the underlying mud. The summer of 1979 was the warmest and wettest for the period...
Proterozoic zircon from augen gneiss, Yukon-Tanana Upland, east-central Alaska
John N. Aleinikoff, Cynthia Dusel-Bacon, Helen L. Foster, Kiyoto Futa
1981, Geology (9) 469-473
U-Th-Pb analyses of zircons from an ortho-augen gneiss body in the Yukon-Tanana Upland of east-central Alaska yield strong evidence for the presence of early Proterozoic material in this area. U-Pb data define a chord that intersects concordia at about 2,300 and 345 m.y. We consider two interpretations: (1) the protolith...
Holocene pollen and sediment record from the tangle lakes area, central Alaska
Thomas A. Ager, John D. Sims
1981, Palynology (5) 85-98
Pollen and sediments have been analyzed from a 5.5 meter‐length core of lacustrine sediments from Tangle Lakes, in the Gulkana Upland south of the Alaska Range (63 ° 01 ‘ 46”; N. latitude, 146° 03 ‘ 48 “ W. longitude). Radiocarbon ages indicate that the core spans the last 4700...

Decline and present status of breeding Peregrine Falcons in Oregon
Charles J. Henny, M.W. Nelson
1981, Murrelet (62) 43-53
Unprecedented declines of the Peregrine Falcon (Falco peregrinus) throughout much of the Northern Hemisphere became apparent during the Madison Peregrine Falcon Conference in 1965 (Hickey 1969). Data from Britain were the most detailed; broken or missing eggs were much more common in 1949-56 than they had been in earlier years...
Suspected Great Blue Heron population decline after a severe winter in the Columbia Basin
Lawrence J. Blus, Charles J. Henny
1981, Murrelet (62) 16-18
The wintering range of the Great Blue Heron (Ardea herodias) extends further north than does that of any other member of the Ciconiiformes in North America. The northern limits of its range extend along the Pacific coast into southeastern Alaska, into Massachusetts on the Atlantic coast, and inland into...
A Pleistocene sand sea on the Alaskan Arctic Coastal Plain
L. D. Carter
1981, Science (211) 381-383
A ridge and thermokarst-basin landscape that is strikingly portrayed in Landsat winter imagery consists of large Pleistocene dunes that have been modified by younger eolian activity and thermokarst processes. This is the most extensive area of large stabilized dunes yet reported in the North American Arctic; the...
Early evolution of the Bering Sea by collision of oceanic rises and North Pacific subduction zones
Z. Ben-Avraham, Alan K. Cooper
1981, GSA Bulletin (92) 485-495
Three major bathymetric features exist in the Bering Sea: Shirshov Ridge, Bowers Ridge, and Umnak Plateau. New refraction data over Umnak Plateau and previous geophysical data across Bowers Ridge indicate that a thickened welt of crustal material is present beneath both features. The crustal structure is transitional between oceanic and...
