J. D. Friedman, G. Heiken, D. Randerson, D.S. McKay
1976, Journal of Volcanology and Geothermal Research (1) 305-329
Hasselblad and Nikon stereographic photographs taken from Skylab between 9 June 1973 and 1 February 1974 give synoptic plan views of several entire eruption clouds emanating from Sakura-zima volcano in Kagoshima Bay, Kyushu, Japan. Analytical plots of these stereographic pairs, studied in combination with meteorological data, indicate that the eruption...
Hydrology of the North Cascades region, Washington: 1. Runoff, precipitation, and storage characteristics
Lowell A. Rasmussen, Wendell V. Tangborn
1976, Water Resources Research (12) 187-202
The time and space distributions of measured precipitation and measured runoff and of spring storage, which is approximately equal to the subsequent summer runoff of snowmelt and stored groundwater, have been analyzed for the North Cascades region of Washington. Neither precipitation nor runoff shows a consistent relationship with altitude, chiefly...

Record of early earthquakes in Northeastern United States provide limited information on effects in pennsylvania until 1737, 55 years after the first permanent settlement was established. A very severe earthquake that centered in the St.Lawrence River region in 1663 may have been felt in Pennsylvania, but historical accounts are not...

Hydrology of the North Cascades region, Washington: 2. A proposed hydrometeorological streamflow prediction method
Wendell V. Tangborn, Lowell A. Rasmussen
1976, Water Resources Research (12) 203-216
On the basis of a linear relationship between winter (October-April) precipitation and annual runoff from a drainage basin (Rasmussen and Tangborn, 1976) a physically reasonable model for predicting summer (May-September) streamflow from drainages in the North Cascades region was developed. This hydrometeorological prediction method relates streamflow for a season beginning...

1976, Earthquake Information Bulletin (USGS) (8) 18-23
Geothermal energy-from heat deep inside the Earth- is a vast potential source of power. This article is the second part of a series on geothermal energy, the first part of which was in volume 8, number 1, of the Earthquake Information Bulletin (January-February 1976). Part 1 of this series described the...
Duck nesting in fields of undisturbed grass-legume cover
Harold F. Duebbert, J. T. Lokemoen
1976, Journal of Wildlife Management (40) 39-49
A study of dabbling duck (Anatinae) nesting was conducted during 1971-73 on nine 12- to 54-ha Cropland Adjustment Program fields in the prairie pothole region of north-central South Dakota. The tall, dense vegetation was comprised of introduced cool-season grasses and legumes, primarily smooth bromegrass (Bromus inermis), intermediate wheatgrass (Agropyron intermedium),...

Reduction of mare basalts by sulfur loss
R. Brett
1976, Geochimica et Cosmochimica Acta (40) 997-1004
Metallic Fe content and S abundance are inversely correlated in mare basalts. Either S volatilization from the melt results in reduction of Fe2+ to Fe0 or else high S content decreases Fe0 activity in the melt, thus explaining the correlation. All considerations favor the model that metallic iron in mare basalts is due...
Thermomagnetic analysis of meteorites, 3. C3 and C4 chondrites
J.M. Herndon, M.W. Rowe, E.E. Larson, D.E. Watson
1976, Earth and Planetary Science Letters (29) 283-290
Thermomagnetic analysis was made on samples of all known C3 and C4 chondrites in a controlled oxygen atmosphere. Considerable variation was noted in the occurrence of magnetic minerals, comparable to the variation observed earlier in the C2 chondrites. Magnetite was found...
Foraminiferal biostratigraphy of the shelf edge: a key to late Quaternary paleoenvironments
C. Wylie Poag, B.R. Sidner
1976, Palaeogeography, Palaeoclimatology, Palaeoecology (19) 17-37
Foraminiferal assemblages in eight piston cores from West Flower Garden Bank at the edge of the Texas continental shelf contain a nearly complete record of late Quaternary paleoclimatic and geologic events. The faunas are divisible into three distinct successive biofacies on the basis of both planktonic and benthic foraminifers: the...

Identification of excess 40Ar by the 40Ar 39Ar, age spectrum technique
M. A. Lanphere, G. Brent Dalrymple
1976, Earth and Planetary Science Letters (32) 141-148
40Ar/39Ar incremental heating experiments on igneous plagioclase, biotite, and pyroxene that contain known amounts of excess40Ar indicate that saddle-shaped age spectra are diagnostic of excess40Ar in igneous minerals as well as in igneous rocks. The minima in the age spectra approach but...
Simulation of streamflow of Flambeau River at Park Falls, Wisconsin to define low-flow characteristics
William R. Krug
1976, Water-Resources Investigations Report 76-116
Daily streamflows of the Flambeau River at Park Falls, Wisconsin , were simulated for a 31-year period. Streamflow was simulated using a streamflow-routing model. These simulated daily flows were analyzed for summer (June 1-October 31) low-flow frequency. The resultant 7-day, 10-year summer low flow is 260 cubic feet per second....

The computer program CABFAC for Q-mode factor analysis of geologic data has been extended for use with data having constant row-sums. Another program, QMODEL, reads an output file from CABFAC and can be used to develop a variety of Q-mode models. The models serve to reproduce estimates of the original...

The Unit Sampling Method is a binomial sampling method applicable to the study of fauna preserved in rocks too well cemented to be disaggregated. Preliminary estimates of the probability of detecting each group in a single sampling unit can be converted to estimates of the group's volumetric abundance by means...

During its first 30 orbits around Mars, the Viking orbiter took approximately 1000 photographic frames of the surface of Mars with resolutions that ranged from 100 meters to a little more than 1 kilometer. Most were of potential landing sites in Chryse Planitia and Cydonia and near Capri Chasma. Contiguous...

The first photographs ever returned from the surface of Mars were obtained by two facsimile cameras aboard the Viking 1 lander, including black-and-white and color, 0.12?? and 0.04?? resolution, and monoscopic and stereoscopic images. The surface, on the western slopes of Chryse Planitia, is a boulder-strewn deeply reddish desert, with...
