1981, Miscellaneous Field Studies Map 1195
With the development of remote sensing technology has come the capability of defining and mapping plant communities by means of their spectral properties. Such maps will be an important aid in resource evaluation and management, especially in densely vegetated and remote areas of the world. This study in part of a...

Appearance and distribution of the gas hydrate reflection in the Blake Ridge region, offshore southeastern United States
Charles K. Paull, William P. Dillon
1981, Miscellaneous Field Studies Map 1252
A strong reflection parallel to the sea floor has been observed in seismic-reflection profiles in the Blake Ridge area off the southeastern United States. This reflection occurs at a subbottom depth of 400 to 700 m, in water depths of 750 to 3750 m. Because the reflection parallels the sea...

Interpretation of an aerial radiometric survey of the San Gorgonio Wilderness Area and vicinity, San Bernardino County, California
James A. Pitkin, Joseph S. Duval
1981, Miscellaneous Field Studies Map 1161-B
The aerial radiometric data for the San Gorgonio Wilderness Area show slight correlation with mapped geology and contain no information of economic significance. Precambrian and modified Precambrian crystalline rocks have more eTh compared to Mesozoic plutonic rocks and one rock unit mapped as a pluton has slightly more K. These...
Aeromagnetic map of the Mokelumne Wilderness and contiguous Rare II further planning areas, central Sierra Nevada, California
