Kendall A. Dickinson
1988, Sedimentary Geology (54) 303-320
Sideritic lacustrine mudstone was found in drill core from a uranium deposit in the Death Valley area in the eastern part of the Seward Peninsula, Alaska. The precursor sediments for this rock were deposited in an unusual “iron-meromictic” Eocene lake, herein named Lake Tubutulik, which occupied part of the Boulder...
An improved dark-object subtraction technique for atmospheric scattering correction of multispectral data
Pat S. Chavez Jr.
1988, Remote Sensing of Environment (24) 459-479
Digital analysis of remotely sensed data has become an important component of many earth-science studies. These data are often processed through a set of preprocessing or “clean-up” routines that includes a correction for atmospheric scattering, often called haze. Various methods to correct or remove the additive haze component have been...
Daily cycles in coastal dunes
R. E. Hunter, Bruce M. Richmond
1988, Sedimentary Geology (55) 43-67
Daily cycles of summer sea breezes produce distinctive cyclic foreset deposits in dune sands of the Texas and Oregon coasts. In both areas the winds are strong enough to transport sand only during part of the day, reach a peak during the afternoon, and vary little in direction during the...

Natural aggregates of the conterminous United States
William H. Langer
1988, Bulletin 1594
Crushed stone and sand and gravel are the two main sources of natural aggregates. These materials are commonly used construction materials and frequently can be interchanged with one another. They are widely used throughout the United States, with every State except two producing crushed stone. Together they amount to about...
Flow in the unsaturated zone, Tucson, Arizona
D. D. Graham
1988, Open-File Report 88-329
Field studies in Tucson, Arizona were conducted based on the discovery of contaminants in groundwater from a substantial number of municipal and private wells, and evidence that the presence of a thick unsaturated zone does not prevent the eventual migration of contaminants to regional groundwater systems. A pulse of water...
Selected annotated bibliographies for adaptive filtering of digital image data
Margaret Mayers, Lynnette Wood
1988, Open-File Report 88-104
Digital spatial filtering is an important tool both for enhancing the information content of satellite image data and for implementing cosmetic effects which make the imagery more interpretable and appealing to the eye. Spatial filtering is a context-dependent operation that alters the gray level of a pixel by computing a...

Carolyn Johns, Samuel N. Luoma, Virginia Elrod
1988, Estuarine, Coastal and Shelf Science (27) 381-396
Spatial distributions of selenium were determined in fine-grained, oxidized, surface sediments and in two benthic bivalves (Corbicula sp., a suspension-feeding freshwater clam, and Macoma balthica, a deposit-feeding brackish-water clam) within San Francisco Bay, the San Joaquin River and three river systems unlikely to be subject to selenium inputs. Biologically available selenium enters...
Relationships between silicic plutonism and volcanism: Geochemical evidence
R. Macdonald, R.L. Smith
1988, Transactions of the Royal Society of Edinburgh, Earth Sciences (79 ) 257-263
Field associations (voluminous ash flow deposits, rhyolitic stocks and dykes, ring complexes), evidence of repeated influxes of mafic magma, and thermal constraints indicate that many high-level silicic plutons (magma chambers) acted as open systems for considerable parts of their history. The long thermal lifetime, as well as other evidence from...

Ken Bovee, J.R. Zuboy
1988, Book
The development of reliable habitat suitability criteria is critical to the successful implementation of the Instream Flow Incremental Methodology (IFIM), or any other habitat based evaluation technology. It is also a fascinating topic of research, for several reasons. First, the “science” of habitat quantification is relatively young. Descriptions of habitat...
Monitoring wildlife habitat: A critique of approaches
Mel Schamberger
1988, Statistical Journal of the United Nations ECE (5) 303-313
Naturalists have long recognized that wildlife cannot exist in a natural state without adequate habitat. Habitat monitoring is an effort to monitor the physical conditions that provide life support for the species, given the underlying assumption that if the habitat is available the species will respond and fill that habitat...
