Geological and technological assessment of artificial reef sites, Louisiana outer continental shelf
D.L. Pope, T.F. Moslow, J.B. Wagner
1993, Ocean and Coastal Management (20) 121-145
This paper describes the general procedures used to select sites for obsolete oil and gas platforms as artificial reefs on the Louisiana outer continental shelf (OCS). The methods employed incorporate six basic steps designed to resolve multiple-use conflicts that might otherwise arise with daily industry and commercial fishery operations, and...
Sorption of N2 and EGME vapors on some soils, clays, and mineral oxides and determination of sample surface areas by use of sorption data
C. T. Chiou, D.W. Rutherford, M. Manes
1993, Environmental Science & Technology (27) 1587-1594
Vapor sorption isotherms of ethylene glycol monoethyl ether (EGME) at room temperature and isotherms of N2 gas at liquid nitrogen temperature were determined for various soils and minerals. The N2 monolayer capacities [Qm (N2)] were calculated from the BET equation and used to determine the surface areas. To examine whether...
Geomorphic observations of rivers in the Oregon Coast Range from a regional reconnaissance perspective
S. Rhea
1993, Geomorphology (6) 135-150
Changes in long profile, gradient, gradient index, pseudo-hypsometric integral, valley incision, and sinuosity fractal dimension for rivers in western Oregon were studied to determine their usefulness in assessing an hypothesis of differential uplift within the Coast Range. All data were gathered from...
Prediction by regression and intrarange data scatter in surface-process studies
T.J. Toy, W. R. Osterkamp, K.G. Renard
1993, Environmental Geology (22) 121-128
Modeling is a major component of contemporary earth science, and regression analysis occupies a central position in the parameterization, calibration, and validation of geomorphic and hydrologic models. Although this methodology can be used in many ways, we are primarily concerned with the prediction of values for one variable from another...
The role of acoustic emission in the study of rock fracture
D. Lockner
1993, International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts (30) 883-899
The development of faults and shear fracture systems over a broad range of temperature and pressure and for a variety of rock types involves the growth and interaction of microcracks. Acoustic emission (AE), which is produced by rapid microcrack growth, is a ubiquitous phenomenon associated with brittle fracture and has...
Carbon isotopic data from test hole USW UZ-1, Yucca Mountain, Nevada
In C. Yang, C.A. Peters, D.C. Thorstenson
1993, Conference Paper, High Level Radioactive Waste Management
Rock-CO2-gas analyses in test hole USW UZ-1 at Yucca Mountain indicate that gas movement in the unsaturated zone is likely through a dry-fracture system with little porewater or caliche-calcite interaction. This is because near-surface ??13C values are of biogenic origin and have changed little throughout the total depth. Post-bomb 14C...
Evaluation of the energy budget method of determining evaporation at Williams Lake, Minnesota, using alternative instrumentation and study approaches
D.O. Rosenberry, A.M. Sturrock, T. C. Winter
1993, Water Resources Research (29) 2473-2483
Best estimates of evaporation at Williams Lake, north central Minnesota, were determined by the energy budget method using optimum sensors and optimum placement of sensors. These best estimates are compared with estimates derived from using substitute data to determine the effect of using less accurate sensors, simpler methods, or remotely...

Lawrence M. Anovitz, E.J. Essene, G.W. Metz, S.R. Bohlen, E.F. Westrum Jr., B. S. Hemingway
1993, Geochimica et Cosmochimica Acta (57) 4191-4204
The heat capacity of a synthetic almandine, Fe3Al2Si3O12, was measured from 6 to 350 K using equilibrium, intermittent-heating quasi-adiabatic calorimetry and from 420 to 1000 K using differential scanning calorimetry. These measurements yield Cp298 = 342.80 ± 1.4 J/mol · K and S298o = 342.60 J/mol · K. Mössbauer characterizations show the almandine to...
Influence of long term climate change on net infiltration at Yucca Mountain, Nevada
Alan I. Flint, Lorraine E. Flint, Joseph Hevesi
1993, Conference Paper, High Level Radioactive Waste Management
Net infiltration and recharge at Yucca Mountain, Nevada, a potential site for a high level nuclear waste repository, are determined both by the rock properties and past and future changes in climate. A 1-dimensional model was constructed to represent a borehole being drilled through the unsaturated zone. The rock properties...

K. P. Gallo, A. L. McNab, Thomas R. Karl, Jesslyn F. Brown, J. J. Hood, J.D. Tarpley
1993, International Journal of Remote Sensing (14) 2223-2230
A vegetation index and radiative surface temperature were derived from NOAA-11 Advanced Very High Resolution Radiometer (AVHRR) data for the Seattle, WA region from 28 June through 4 July 1991. The vegetation index and surface temperature values were computed for locations of weather observation stations within the region and compared...
An earth remote sensing satellite- 1 Synthetic Aperture Radar Mosaic of the Tanana River Basin in Alaska
Charles E. Wivell, Coert Olmsted, Daniel R. Steinwand, Christopher Taylor
1993, Photogrammetric Engineering and Remote Sensing (59) 527-528
Because the pixel location in a line of Synthetic Aperture Radar (SAR) image data is directly related to the distance the pixel is from the radar, terrain elevations cause large displacement errors in the geo-referenced location of the pixel. This is especially true for radar systems with small angles between...
Using multisource data in global land-cover characterization: concepts, requirements, and methods
Jesslyn F. Brown, Thomas R. Loveland, James W. Merchant, Bradley C. Reed, Donald O. Ohlen
1993, Photogrammetric Engineering and Remote Sensing (59) 977-987
Global land-cover data are needed as baseline information for global change research. Multisource data, both coarse resolution satellite data and ancillary data, were used to produce a land-cover characteristics database for the conterqinous United States. Ancillary data, including elevation and ecological region data sets, were critical to the development, refinement, and...
Seasonal use of conservation reserve program lands by white-tailed deer in east-central South Dakota
Jeffrey H. Gould, Kurt J. Jenkins
1993, Wildlife Society Bulletin (21) 250-255
The Conservation Reserve Program (CRP_, a provision of the 1985 Food Security Act, subsidizes landowners to take highly erodible lands out of cultivation and seed them to perennial cover for 10years. In eastern South Dakota, 0.5 million ha were enrolled in the CRP from 1985 to 1990 (Agric. Stabilization and...

Analyzing vegetation dynamics of land systems with satellite data
Jeffery C. Eidenshink, Robert H. Haas
1992, Geocarto International (7) 53-61
Large area assessment of vegetation conditions is a major requirement for understanding the impact of weather on food, fiber, and forage production. The distribution of vegetation is largely associated with climate, terrain characteristics, and human activity. The interpretation of vegetation dynamics from satellite data can be improved by stratifying the...

Jon A. Lebo, James L. Zajicek, James N. Huckins, Jimmie D. Petty, Paul H. Peterman
1992, Chemosphere (25) 697-718
A method is given for the recovery, cleanup, and analysis of polycyclic aromatic hydrocarbons (PAHs) that have been sequestered in SPMDs (semipermeable membrane devices). SPMDs are polymeric membranes enclosing lipids, and mimic the bioconcentration process of aquatic animals. SPMDs are used as passive, in situ monitors of contamination by organic...

1992, Technical Publication 104
A seepage study was made during 1989 on selected reaches of the Timpanogos, Wasatch, Sagebrush and Spring Creek, Upper Charleston, and Lower Charleston Canals in Wasatch County, Utah, to determine gains or losses in discharge. Fluctuations in discharge were adjusted using information from water-stage recorders operated...
