Notes on a broad-band variant of the NCER seismic data multiplex system for use with field tape recorders
Jerry P. Eaton
1976, Open-File Report 76-87
Tests of the standard NCER multiplex system recorded and played back on both the Bell and Howell 3700B (about 0.1% tape speed variation) and on the Sony TC-126 cassette recorder (about 1% tape speed variation) showed that subtractive compensation employing a reference frequency multiplexed on the data track was remarkably...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: September 1976

1976, Open-File Report 76-300-I
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;...

Measured and simulated ground-water levels in the Franklin area, southeastern Virginia
O. J. Cosner
1976, Water-Resources Investigations Report 76-83
The Lower Cretaceous aquifer is the principal source of water in Southeastern Virginia. Synoptic water-level measurements made since 1970 have been used to verify a digital model of the aquifer. Measurements made in December 1973, August and December 1974 were used to further verify the model, using updated pumpage for...
Teton Dam flood of June 1976, Rose quadrangle, Idaho
John H. Bartells, Larry L. Hubbard
1976, Hydrologic Atlas 578
The failure of the Teton Dam caused extreme flooding along the Teton River, Henrys Fork, and Snake River in southeastern Idaho on June 5-8, 1976. No flooding occurred downstream from American Falls Reservoir. The inundated areas and maximum water-surface elevations are shown in a series of 17 hydrologic atlases. The...
Availability of ground water in the Middle Connecticut River basin, west-central New Hampshire
John E. Cotton
1976, Water-Resources Investigations Report 76-18
This report provides a guide for ground-water exploration and for water- and land-use planning and management. Sufficient amounts of water to supply single family homes are available from the bedrock aquifer nearly everywhere in the middle Connecticut River basin. Relatively thin and narrow, unconsolidated aquifers of sand or sand and...

Low-Flow Characteristics and Mean Annual Discharge of North Branch Manitowoc River at Potter, Wisconsin
B. K. Holmstrom
1976, Open-File Report 76-204
The low-flow characteristics presented in this report are the annual minimum 7-day mean flows at the 2-year recurrence interval and 10-year recurrence interval. They were determined just downstream from the confluence of the three streams forming the North Branch Manitowoc River and, based on natural-flow conditions, are 0.0 cubic foot...

Ground water in the San Juan metropolitan area, Puerto Rico
H. R. Anderson
1976, Water-Resources Investigations Report 75-41
Ground water in the San Juan, Puerto Rico, area has played a declining role in water supply since the completion of the Lofza reservoir project in the early 1950's. Ground-water potential is limited because of the small size of the aquifers and susceptibility to seawater intrusion. Of the 30 million...

1976, Open-File Report 76-567
Reconnaissance geochemical sampling has been conducted by the Lithium Resource Program of the United States Geological Survey for much of the Western U.S. Sediment, rock, and brine samples have been collected in many states, but this report describes just those solid samples collected in Nevada. Further reports by other members...

Preliminary overview map of volcanic hazards in the 48 conterminous United States
D. R. Mullineaux
1976, Miscellaneous Field Studies Map 786
Volcanic eruptions and related phenomena can be expected to occur in the Western United States, and in some places are potentially hazardous enough to be considered in longe-range land-use planning. But the immediate risk from volcanic hazards is low because eruptions are so infrequent in the conterminous United States that...
