Factors correlated with incidence of fishbite on deep-sea mooring lines

Data from 399 moored stations established over the years 1967 through 1978 have been analyzed with reference to fishbite. Fishbite appears to have been a significant hazard as it was found in 22% of the lines placed within 40 degrees of the equator and where parts of the lines were at 2000 meters depth or less. Latitude, depth of water, and distance of mooring components beneath the surface were found to be correlated with incidence of fishbite; duration of a mooring was not.Prepared for the Office of Naval Research under Contract N00014-76-C-0197; NR 083-400 and the National Data Buoy Office of the National Oceanic and Atmospheric Administration under Contract NA-79-QA-A-00475

Mineral exploration potential of ERTS-1 data

The author has identified the following significant results. ERTS-1 imagery of an area approximately 15,000 square miles in Arizona was interpreted for regional structure and tectonic units. Eight fault systems were identified by trend, of which two, northeast and northwest, are considered to be related to porphyry copper mineralization. Nine tectonic units can be identified on the imagery as distinct geological identities. The boundaries between these units can be correlated with theoretical shear directions related to the San Andreas stress system. Fourier analysis of the N 50 W fault trend indicates a fundamental spacing between Fourier energy maxima that can be related to distances between copper deposits
