R. L. Reynolds
1982, Earth and Planetary Science Letters (61) 381-391
Petrographic and geochemical studies have yielded information on the time-space relationships of the post-depositional alteration of detrital titanomagnetite (Ti-mt) in fine- to medium-grained sandstone from unoriented core samples (taken below the water table at depths of 30–45 m) of the Miocene...

1982, Physics of the Earth and Planetary Interiors (30) 145-156
A comprehensive data set of selected teleseismic P-wave arrivals and local-network P- and S-wave arrivals from large earthquakes occurring at all depths within a small section of the central Aleutians is used to examine the general problem of earthquake location in island arcs. Reference hypocenters for this special data set...
Nutrient exchange across the sediment-water interface in the Potomac River estuary

1982, Estuarine, Coastal and Shelf Science (15) 395-413
The flux of ammonia, phosphate, silica and radon-222 from Potomac tidal river and estuary sediments is controlled by processes occurring at the sediment-water interface and within surficial sediment. Calculated diffusive fluxes range between 0·6 and 6·5 mmol m−2 day−1 for ammonia, 0·020 and 0·30 mmol m−2 day−1 for phosphate, and 1·3 and 3·8 mmol...

A working conference was held in Sioux Falls, South Dakota, 12-14 November, 1980 dealing with Landsat classification Accuracy Assessment Procedures. Thirteen formal presentations were made on three general topics: (1) sampling procedures, (2) statistical analysis techniques, and (3) examples of projects which included accuracy assessment and the associated costs, logistical...

1982, Miscellaneous Field Studies Map 1395-A
The Wilderness Act (Public Law 88-577, September 3, 1964) and related acts require the U.S. Geological Survey and the U.S. Bureau of Mines to survey certain areas on Federal lands to determine their mineral-resource potential. Results must be made available to the public and be submitted to the President and...
Petrology and trace element geochemistry of the Honolulu volcanics, Oahu: Implications for the oceanic mantle below Hawaii
D.A. Clague, F.A. Frey
1982, Journal of Petrology (23) 447-504
The Honolulu Volcanics comprises small volume, late-stage (post-erosional) vents along rifts cutting the older massive Koolau tholeütic shield on Oahu, Hawaii. Most of these lavas and tuff of the Honolulu Volcanics have geochemical features expected of near-primary magmas derived from a peridotite source containing Fo87–89 olivine; e. g. 100 Mg/(Mg...
USGS aerial resolution targets.
P.H. Salamonowicz
1982, Photogrammetric Engineering and Remote Sensing (48) 1469-1473
It is necessary to measure the achievable resolution of any airborne sensor that is to be used for metric purposes. Laboratory calibration facilities may be inadequate or inappropriate for determining the resolution of non-photographic sensors such as optical-mechanical scanners, television imaging tubes, and linear arrays. However, large target arrays imaged...
Subcellular distribution of mercury in liver of lake trout (Salvelinus namaycush)

Mercury was found primarily (80%) in the submicroscopic material (magnification x < 7700) of environmentally exposed adult lake trout from Lake Michigan, USA....
Techniques for using iron crucibles in experimental igneous petrology.
C.R. Thornber, J.S. Huebner
1982, American Mineralogist (67) 1144-1154
Some iron crucibles contain impurities of Mn, Ti and other elements. Such impurities may alter the fO2 of the system and induce crucible-charge interactions. Pretreatment of impure iron crucibles in a CO2-CO atmosphere at 1050oC, under conditions slightly more reducing than Fe-Fe1-xO, minimizes undesirable changes in the bulk composition of...
Cyclic deposits and hummocky cross-stratification of probable storm origins in Upper Cretaceous rocks of the Cape Sebastian area, southwestern Oregon

Accumulation by fish of contaminants released from dredged sediments
James G. Seelye, Robert J. Hesselberg, Michael J. Mac
1982, Environmental Science & Technology (16) 459-464
Inasmuch as the process of dredging and disposing of dredged materials causes a resuspension of these materials and an increase in bioavailability of associated contaminants, we conducted a series of experiments to examine the potential accumulation by fish of contaminants from suspended sediments. In the first experiment we compared accumulation...
