Geologic conditions in the Baltimore Canyon Trough area: A summary of U.S.G.S. second-year environment studies
Harley J. Knebel
1978, Open-File Report 78-921
Geologic studies of the outer Continental Shelf off the Middle Atlantic States (Baltimore Canyon Trough Area) have been carried out for two years to assess conditions and hazards which might cause or distribute oil spills and other potential pollution associated with petroleum exploration and development. These detailed investigations were requested...
Low-cost computer classification of land cover in the Portland area, Oregon, by signature extension techniques
Leonard Gaydos
1978, Open-File Report 78-186
Computer-aided techniques for interpreting multispectral data acquired by Landsat offer economies in the mapping of land cover. Even so, the actual establishment of the statistical classes, or "signatures," is one of the relatively more costly operations involved. Analysts have therefore been seeking cost-saving signature extension techniques that would accept training...

Virgin Islands sand resource study
Charles Ward Holmes
1978, Open-File Report 78-919
The depletion of sand resources in the Virgin Islands has necessitated the search for more economical supplies. The dynamic processes which produce sand in the nearshore environments are very slow, and removal of this material would cause a depletion of beaches upon which the island economy is predicated. A search...
