Land evaluation studies with remote sensors in the infrared and radar regions
David S. Simonett
1968, Open-File Report 68-250
This paper reviews the literature, especially of the last two years, dealing with remote sensor evaluation of surface and shallow sub-surface characteristics, employing remote sensors in the infrared (1.5p. - 14p.) and radar (0.5 cm - 100 cm) regions. Imaging and non-imaging sensors are examined to assess their current status...
Carbonate rocks of Cambrian and Ordovician age in the Lancaster quadrangle, Pennsylvania
Harold Meisler, Albert E. Becher
1968, Bulletin 1254-G
Detailed mapping has shown that the carbonate rocks of Cambrian and Ordovician age in the Lancaster quadrangle, Pennsylvania, can be divided into 14 rock-stratigraphic units. These units are defined primarily by their relative proportions of limestone and dolomite. The oldest units, the Vintage, Kinzers, and Ledger Formations of Cambrian age,...
Effects of surface mining on fish and wildlife in Appalachia
Joseph A. Boccardy, William M. Spaulding Jr.
1968, Resource Publication 65
This report on the effects of strip and surface mining on the fish and wildlife resources in eight Appalachian States is based in part on observation made during a tour of strip and surface mined area by the authors, as members of a team of specialist from six Federal agencies....
Preliminary interpretation of a seismic-refraction profile across the Large Aperture Seismic Array, Montana
C.A. Borcherdt, John C. Roller
1968, Open-File Report 68-15
A reversed seismic-refraction profile extending northeastward from Greycliff, Montana, across the Large Aperture Seismic Array (LASA) to Charleson, North Dakota, indicates that the crust of the earth consists of two layers with P-wave velocities of 6.1 km/sec and 6.7 km/sec, and that the upper-mantle velocity is 8.3 km/sec. The Mohorovicic...
