The screech owl: Its life history and population ecology in northern Ohio
Laurel F. VanCamp, Charles J. Henny
1975, North American Fauna 71
The screech owl (Otus asio) is native to North America and breeds throughout the United States and in portions of Canada and Mexico. It is a small owl, 20 cm (8 in) in length from the tip of the bill to the tip of the tail, with a wing span...
Water resources of the Lake of the Woods watershed, north-central Minnesota
John O. Helgesen, Gerald F. Lindholm, Donald W. Ericson
1975, Hydrologic Atlas 544
The Lake of the Woods watershed is an area of about 2,900 square miles (7,500 km), the northern limit of which is part of the boundary between the United States and Canada. Drainage is to Lake of the Woods, either directly or by the Rainy River. The watershed includes about...
Water resources of the Mississippi and Sauk Rivers Watershed, central Minnesota
John O. Helgesen, Donald W. Ericson, Gerald F. Lindholm
1975, Hydrologic Atlas 534
A variety of glacial landforms (moraines, till plains, drumlin fields and outwash plains) characterized the 3,890-square mile Mississippi and Sauk Rivers watershed. Underlying the glacial drift are Cambrian and Precambrian sedimentary rocks in the southeastern part of the watershed and Precambrian igneous and metamorphic rocks elsewhere. Surface drainage is entirely to the...
ERTS imagery for ground-water investigations
Gerald K. Moore, Morris Deutsch
1975, Ground Water (13) 214-226
ERTS imagery offers the first opportunity to apply moderately high-resolution satellite data to the nationwide study of water resources. This imagery is both a tool and a form of basic data. Like other tools and basic data, it should be considered for use in ground-water investigations. The main advantage of...

College and university sources of remote sensing information
Timothy C. Bidwell
1975, Photogrammetric Engineering and Remote Sensing (41) 1273-1284
Research in remote-sensing applications has increased dramatically since the launch of the Earth Resources Technology Satellite-l (ERTS-l, renamed LANDSAT-I) and Skylab's Earth Resources Experiment Package (EREP). It is becoming increasingly more difficult to keep abreast of university research publications related to remote sensing. To assist researchers in locating those universities...
The interior of the earth
Eugene C. Robertson
1975, Report
The center of the Earth lies nearly 4,000 miles beneath our feet. At present the nature of the Earth's interior is known only from indirect evidence collected from studies of rocks and minerals, seismic waves, heat flow from the interior, and the Earth's gravity and magnetic field and through comparisons...
Movement of spilled oil as predicted by estuarine nontidal drift
T. J. Conomos
1975, Limnology and Oceanography (20) 159-173
Information on water movement obtained from bimonthly releases of surface and seabed drifters in the San Francisco Bay and adjacent Pacific Ocean is used to understand major processes controlling dispersal of oil after a spill of 3,200 m3 of Bunker C in the bay in January 1971. River-induced nontidal estuarine...
Paleotectonic investigations of the Pennsylvanian System in the United States, Part I: Introduction and regional analyses of the Pennsylvanian System
Edwin D. McKee, Eleanor J. Crosby, George O. Bachman, Kenneth G. Bell, George H. Dixon, Sherwood E. Frezon, Ernest E. Glick, William P. Irwin, William W. Mallory, William J. Mapel, Edwin K. Maughan, George E. Prichard, Gerald L. Shideler, Gary F. Stewart, Harold R. Wanless, Richard F. Wilson
1975, Professional Paper 853-1
The Pennsylvanian is the fourth geologic system to be analyzed and synthesized by geologists of the U.S. Geological Survey in the form of a paleotectonic study covering the conterminous United States. Earlier investigations were of the Jurassic, Triassic, and Permian Systems. Results were published as Miscellaneous Geologic Investigation Maps I-175,...
Earthquakes; March-April 1975
W. J. Person
1975, Earthquake Information Bulletin (USGS) (7) 21-22
There were no major earthquakes (magnitude 7.0-7.9) in March or April; however, there were earthquake fatalities in Chile, Iran, and Venezuela and approximately 35 earthquake-related injuries were reported around the world. In the United States a magnitude 6.0 earthquake struck the Idaho-Utah border region. Damage was estimated at about a...
Author index to published ERTS-1 reports
Timothy C. Bidwell, Cheryl A. Mitchell
1975, Report
This index has been compiled to assist the reader in locating and obtaining reports on the 334 scientific experiments conducted under the National Aeronautics and Space Administration (NASA) Earth Resources Technology Satellite-1 (ERTS-1) (renamed Landsat) program.  Each NASA-designated experimenter was required to submit written reports on his investigation: these were...
