Summary of chemical and radiochemical monitoring of water for the Cannikin event, Amchitka Island, Alaska, fiscal year 1972
L.J. Schroder, Wilbur C. Ballance
1973, Report
An increased dissolved-solids content was found immediately after the Cannikin event (November 6, 1971) at most of 10 locations in a water-sampling network established in 1967 and revised in September 1971. The observed dissolved-solids content increase was within the seasonal range that has been observed at these locations. No measurable increase...
Yukon River: Evidence for extensive migration during the Holocene transgression
H.J. Knebel, J.S. Creager
1973, Science (179) 1230-1232
The shift of the Yukon River, during the Holocene sea-level transgression, from south of Nunivak Island during the Wisconsin maximum to its present location (a distance greater than 300 kilometers) is indicated by remanent channels, distinct subbottom structures, deltaic sediments, and anomalous rates of sediment accumulation on the continental shelf...
Drought displaced movement of North American pintails into Siberia
Charles J. Henny
1973, Journal of Wildlife Management (37) 23-29
During the years 1954-70, 230 pintails (Anas acuta) banded in North America were reported from eastern Asia, primarily Siberia. Most of the birds were shot on the breeding grounds in May. The movement into eastern Asia of pintails banded in the interior of North America was directly correlated with the...
Snowy owl predation on lapland longspur nestlings recorded on film
T. W. Custer
1973, The Auk (90) 433-435
 During the summer of 1971 I investigated the breeding biology of the Lapland Longspur, Calcarius lapponicus, near Barrow, Alaska. To obtain data on incubation and feeding patterns of nesting longspurs, time-lapse cameras (Minolta Autopak-8 D6 super-8 movie cameras equipped with an Intervalometer-P time-lapse device) were positioned at several nests throughout...
Surface-water investigations at Barrow, Alaska
Stanley H. Jones
1972, Report
The U.S. Public Health Service is currently developing plans for a long-term water supply and sewage treatment system for the village of Barrow, Alaska. To assist in planning, the U.S. Geological Survey was requested to initiate a cooperative streamflow data-collection program with the U.S. Public Health Service in June 1972...
Residues of organochlorine pesticides, polychlorinated biphenyls, and mercury in bald eagle eggs and changes in shell thickness--1969 and 1970
Stanley N. Wiemeyer, B.M. Mulhern, F.J. Ligas, R.J. Hensel, J.E. Mathisen, F.C. Robards, S. Postupalsky
1972, Pesticides Monitoring Journal (6) 50-55
Twenty-three bald eagle eggs collected in Alaska, Maine, Michigan, Minnesota, and Florida during 1969 and 1970 were analyzed for organochlorine pesticides, polychlorinated biphenyls, and mercury. All eggs contained residues of DDE, dieldrin, PCB's, and mercury. Average residue concentrations were lowest in eggs from Alaska. Significant eggshell thinning...
Hydraulic testing of hole UA-1-HTH-1, Amchitka Island, Alaska
Wilbur C. Ballance, G.A. Dinwiddie
1972, Report
Total depth of the hole was 1,054 meters (3,458 feet) but, because of borehole erosion and bridging, only about 198 meters (650 feet) of the hole was·hydraulically tested with straddle packers. Some information was obtained on the lower part of the hole by use of the pressure recorders which are...
Channel erosion surveys along proposed TAPS route, Alaska, July 1971
Joseph M. Childers
1972, Report
The U.S. Geological Survey has the threefold responsibility along the proposed route of the Trans-Alaska Pipeline System (TAPS): to investigate possible hydroloqic hazards to the pipeline, to investigate possible impacts of the pipeline on water resources, and to develop a better understanding of Arctic hydrology. Because the proposed pipeline route...
Middle pleistocene mollusks from St. Lawrence Island and their significance for the paleo-oceanography of the Bering Sea
D.M. Hopkins, R.W. Rowland, W. W. Patton Jr.
1972, Quaternary Research (2) 119-134
Drift, evidently of Illinoian age, was deposited on St. Lawrence Island at the margin of an ice cap that covered the highlands of the Chukotka Peninsula of Siberia and spread far eastward on the continental shelf of northern Bering Sea. Underlying the drift on the northwestward part of the island...
Influence of grounding ice on the Arctic shelf of Alaska
E. Reimnitz, P. Barnes, T. Forgatsch, C. Rodeick
1972, Marine Geology (13) 323-334
Alaska's Beaufort Sea shelf is characterized by small-scale relief with an average amplitude of 1–2 m and wavelength of 50–100 m. Diving observations confirm that much of the bottom roughness reflects the action of grounded ice. Except for areas in the shadow of...
