Fall foods of migrant common snipe in North Dakota
E.K. Fritzell, G.A. Swanson, M.I. Meyer
1979, Journal of Wildlife Management (43) 253-257
Studies of foods consumed by common snipe (Capella gallinago) during fall migration (Sperry 1940, Erickson 1941, Choate in Tuck 1972, Tuck 1972) have shown that diets vary among habitats. More recently, Fogarty and Arnold (1977) expressed the need for more detailed information on snipe food habits and more refined knowledge...

Marsh nesting by mallards
Gary L. Krapu, L.G. Talent, T.J. Dwyer
1979, Wildlife Society Bulletin (7) 104-110
Nest-site selection by mallard (Anas platyrhynchos) hens was studied on a 52-km2, privately owned area in the Missouri Coteau of south-central North Dakota during 1974-77. Sixty-six percent of 53 nests initiated by radio-marked and unmarked hens were in wetlands in dense stands of emergent vegetation and usually within 50 m...

This report lists in tabular form: 61 drainage areas in the Twelvepole Creek basin, of West Virginia, 11 drainage areas of the Big Sandy River basin within West Virginia, and 210 drainage areas in the Tug Fork basin of Virginia, Kentucky, and West Virginia. Drainage areas were compiled in a...
Physiological and biochemical aspects of ozone toxicity to rainbow trout (Salmo gairdneri)
Gary A. Wedemeyer, Nancy C. Nelson, William T. Yasutake
1979, Journal of the Fisheries Research Board of Canada (36) 605-614
An acute toxicity curve for dissolved ozone (O3) in soft water at 10 °C, using 10–13-cm rainbow trout (Salmo gairdneri) as the test species was calculated. The 96-h LC50 (95%, confidence interval) was 9.3 (8.1–10.6) μg/L. The lethal threshold level was about 8 μg/L mandating that a conservative margin of safety be...
Artificial transmission to and susceptibility of Puget Sound fish to viral erythrocytic necrosis (VEN)
John R. MacMillian, Dan Mulcahy
1979, Journal of the Fisheries Research Board of Canada (36) 1097-1101
In Puget Sound, Wash., the incidence of viral erythrocytic necrosis (VEN) varied geographically from 0 to 17% in chum salmon (Oncorhynchus keta) and from 4 to 59% in Pacific herring (Clupea harengus pallasi). The disease was experimentally transmitted by intraperitoneal injection to chum, pink (O. gorbuscha), coho (O. kisutch), chinook (O. tshawytscha), sockeye...

Earthquakes, September-October 1978
W. J. Person
1979, Earthquake Information Bulletin (USGS) (11) 71-73
The months of September and October were somewhat quiet seismically speaking. One major earthquake, magnitude (M) 7.7 occurred in Iran on September 16. In Germany, a magntidue 5.0 earthquake caused damage and considerable alarm to many people in parts of that country. In the United States, the largest earthquake occurred...
Geomagnetic paleointensities by the Thelliers' method from submarine pillow basalts: Effects of seafloor weathering
Sherman Gromme, Edward A. Mankinen, Monte Marshall, Robert S. Coe
1979, Journal of Geophysical Research B: Solid Earth (84) 3553-3575
Measurements of geomagnetic paleointensity using the Thelliers' double‐heating method in vacuum have been made on 10 specimens of submarine pillow basalt obtained from 7 fragments dredged from localities 700,000 years old or younger. In the magnetic minerals, the titanium/iron ratio parameter x and the cation deficiency (oxidation) parameter x were determined by X‐ray diffraction...
The geochemistry of the Fox Hills-Basal Hell Creek Aquifer in southwestern North Dakota and northwestern South Dakota
Donald C. Thorstenson, Donald W. Fisher, Mack G. Croft
1979, Water Resources Research (15) 1479-1498
The Late Cretaceous Fox Hills Formation and the basal portion of the overlying Hell Creek Formation constitute an important aquifer in the Fort Union coal region. Throughout most of southwestern North Dakota and northwestern South Dakota the aquifer is at depths ranging from 1000 to 2000 ft, except for exposures...
Trees as indicators of past movements on the San Andreas Fault
R. E. Wallace, Valmore C. LaMarche Jr.
1979, Earthquake Information Bulletin (USGS) (11) 127-131
Trees are sources of information about fault movements that have occurred before the earliest historical reports. This kind of evidence can be used to improve estimates of when earthquakes will recur on faults known to be seismically active and to identify active faults that have no record of movement during...

Predicting rock bursts in mines
H. Spall
1979, Earthquake Information Bulletin (USGS) (11) 89-94
In terms of lives lost, rock bursts in underground mines can be as hazardous as earthquakes on the surface. So it is not surprising that fo the last 40 years the U.S Bureau of Mines has been using seismic methods for detecting areas in underground mines where there is a...

The first major earthquake (magnitude 7.0 to 7.9) of the year struck in southeastern Alaska in a sparsely populated area on February 28. On January 16, Iran experienced the first destructive earthquake of the year causing a number of casualties and considerable damage. Peru was hit by a destructive earthquake...
Assessing Metallic Resources in Alaska
Donald A. Singer, A. Thomas Ovenshine
1979, American Scientist (67) 582-589
In the last two decades federal and state governments have become in creasingly preoccupied with classi fying public lands according to the uses that may be made of them. One outcome of the classifying can be a change in the land's legal status from one in which any use...
Revised geomagnetic polarity time scale for the interval 0–5 m.y. B.P.
Edward A. Mankinen, G. Brent Dalrymple
1979, Journal of Geophysical Research B: Solid Earth (84) 615-626
A change in the constants used in K‐Ar dating and a significant increase in new data have made a recompilation and recomputation of data used to define the Late Cenozoic K‐Ar polarity time scale highly desirable at this time. All available data in the range 0–5 m.y. have been recalculated...

L. V. Benson, D. L. Leach
1979, Journal of Geochemical Exploration (11) 227-248
During the summer of 1976 waters from tributaries, rivers, springs and wells were sampled in the Walker River Basin. Snow and sediments from selected sites were also sampled. All samples were analyzed for uranium and other elements. The resulting data provide an understanding of the transport of uranium within...
