Structure and evolution of Bering Sea shelf south of St. Lawrence Island Structure and evolution of Bering Sea shelf south of St. Lawrence Island

The virtually featureless Beringian shelf south of St. Lawrence Island is underlain structurally by at least 14 basins. Encompassing a total area of more than 300,000 sq km, most of the basins are either elongate structural sags, grabens, or half (asymmetric) grabens beneath the outer shelf. The regional trend of these basins is northwest, parallel with that of the continental margin...

Coral reef recovery in Florida and the Persian Gulf Coral reef recovery in Florida and the Persian Gulf

Long-term observations and study of coral reef destruction by hurricanes in the Florida Keys show, surprisingly, that although corals are devastated on a grand scale during storms, recovery is rapid. Recovery occurs because of the widespread scattering of live fragments, many of which become growth sites of new colonies. Reef recovery from death by chilling in the Persian Gulf was well...

Textural variation within Great Salt Lake algal mounds Textural variation within Great Salt Lake algal mounds

This chapter discusses textural variation within the Great Salt Lake algal mounds. Great Salt Lake algal mounds contain: (1) a framework of non-skeletal, algally induced aragonite precipitates; (2) internal sediment; and (3) inorganic cement. These three elements create a variety of laminated, poorly laminated, and unlaminated internal textures. Interior framework precipitates bear...

Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: September 1976 Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: September 1976

The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory; therefore it should be regarded as preliminary.

15/16 ips Operation of the Precision Instrument Company Model P15100 tape recorder to record the standard (30 Hz) NCER seismic data multiplex system 15/16 ips Operation of the Precision Instrument Company Model P15100 tape recorder to record the standard (30 Hz) NCER seismic data multiplex system

In recent months the need has arisen to record special seismic networks consisting of a dozen or more standard NCER seismic systems telemetered to a central collection point on a reliable, portable, low-power tape recorder. Because of its simplicity and the ease with which it can be adapted for the purpose, the PI 5100 field recorder should be considered for such use. In the tests...
