1975, Open-File Report 75-13
A numerical model of a salt-wedge estuary developed by Fischer has been expanded and used to calculate the distributions of salinity, temperature, chlorophyll a concentrations, biochemical oxygen demand, and dissolved-oxygen concentrations in the Duwamish River estuary, King County, Wash. With this model, which was calibrated and verified with observed data,...

The geologic story of Isle Royale National Park
N. King Huber
1975, Bulletin 1309
Isle Royale is an outstanding example of relatively undisturbed northwoods lake wilderness. But more than simple preservation of such an environment is involved in its inclusion in our National Park System. Its isolation from the mainland provides an almost untouched laboratory for research in the natural sciences, especially those studies...

U, Th, and K analyses of selected plutonic rocks from west-central Alaska
Thomas P. Miller, Carl M. Bunker
1975, Open-File Report 75-216
Numerous samples of plutonic rocks collected during reconnaissance mapping in western Alaska have been analyzed for K, U, and Th. The U and Th content of the plutonic rocks from the southeastern Seward Peninsula have been discussed in a separate report (Miller and Bunker, 1975); because of the current interest...

1975, Open-File Report 75-345
U.S. Air Force Launch Control Facility 0-0 is located about 3.6 miles (5.6 kilometres) north of Cooperstown, Griggs County, North Dakota. Test drilling indicates that a glacial-drift aquifer located within about 0.2 mile (0.3 kilometre) of the site will supply 2 to 3 gallons per minute (0.13 to 0.19 litre...

Self-calibrating seismic amplifier and telemetry system
John R. Van Schaack
1975, Open-File Report 75-64
A frequency modulated, constant bandwidth, telemetry system has been designed to transmit simultaneously up to 8 channels of seismograph data from remote locations to a central recording site via radio or voice-grade telephone circuit. By utilizing state-of-the-art integrated circuits, the size of the remote unit has been considerably reduced over...
Gravity map of the Nabesna Quadrangle, Alaska
David F. Barnes, Robert L. Morin
1975, Miscellaneous Field Studies Map 655-I
The gravity map of the Nabesna quadrangle indicates significant variations in the densities and thicknesses of the rock units that underlie the quadrangle. Most of this gravity relief is indirectly related to regional topographic relief or lithologic variations that are revealed in the rock outcrops. However, some significant features of...
