Since there is concern that extensive exploratory drilling might degrade most potential disposal sites, geophysical methods become crucial as the only nondestructive means to examine large volumes of rock in three dimensions. Characterization of potential sites requires geophysicists to alter their usual mode of thinking: no longer are anomalies being sought, as in mineral exploration, but rather their absence. Thus the size of features that might go undetected by a particular method take on new significance. Legal and regulatory considerations that stem from this different outlook, most notably the requirements of quality assurance (necessary for any data used in support of a repository license application), are forcing changes in the manner in which geophysicists collect and document their data. -Authors","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geophysical Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"01480227","usgsCitation":"Wynn, J.C., and Roseboom, E., 1987, Role of geophysics in identifying and characterizing sites for high-level nuclear waste repositories.: Journal of Geophysical Research, v. 92, no.

Corrections for isobaric interferences from oxide ions and other diatomic and triatomic ions are made mathematically.

A first indication about the strain path is given by the symmetry of pole figures: coaxial deformation produces orthorhombic pole figures, while non-coaxial deformation yields monoclinic or triclinic pole figures. More quantitative information about the strain history can be obtained by comparing natural textures with experimental ones and with theoretical models. For this comparison, a representation in the sensitive three-dimensional orientation distribution space is extremely important and efforts are made to explain this concept. We have been investigating differences between pure shear and simple shear deformation incarbonate rocks and have found considerable agreement between textures produced in plane strain experiments and predictions based on the Taylor model. We were able to simulate the observed changes with strain history (coaxial vs non-coaxial) and the profound texture transition which occurs with increasing temperature. Two natural calcite textures were then selected which we interpreted by comparing them with the experimental and theoretical results. A marble from the Santa Rosa mylonite zone in southern California displays orthorhombic pole figures with patterns consistent with low temperature deformation in pure shear.

Magma supply rates are low in the earliest and two latest alkalic stages and high in the tholeiitic second stage. Magma storage reservoirs develop at shallow and intermediate depths as the magma supply rate increases during the earliest stage; magma in these reservoirs solidifies as the supply rate declines during the alkalic third stage. These magma storage reservoirs function as hydraulic filters and remove dense xenoliths that the ascending magma has entrained. During the earliest and latest stages, no magma storage zone exists, and mantle xenoliths of lherzolite are carried to the surface in primitive alkalic lava.

This exceptionally well exposed area consists of late Proterozoic metamorphic, intermediate to silicic intrusive, and interlayered clastic sedimentary and intermediate silicic volcanic rocks that have not been studied previously using SMIRR data. Plots or traces of unnormalized SMIRR channel ratios were examined before field studies to locate areas with high spectral contrast, especially in the 2.0 μm to 2.40 μm channels. Reflectance spectra were measured in the laboratory for rock and soil samples collected in these areas, and the mineralogic causes of the main absorption features were determined using X‐ray diffraction. Laboratory SMIRR spectra were produced by convolving the ten SMIRR filters with the laboratory spectra. Then, normalized SMIRR reflectance spectra were generated along the groundtrack using normalization coefficients calculated for a field sample representing a uniform, low‐spectral contrast area. Field evaluation shows that unnormalized SMIRR ratio traces are useful, even without specific mineralogic information, for distinguishing rocks that are characterized by Al‐OH, Mg‐OH, and/or <span class=\"MathJax\" data-mathml=\"<math xmlns=&quot;http://www.w3.org/1998/Math/MathML&quot; overflow=&quot;scroll&quot;><mrow><msub><mi>CO</mi><mrow><mn>3</mn></mrow></msub></mrow></math>\"><span class=\"MathJax\" data-mathml=\"<math xmlns=&quot;http://www.w3.org/1998/Math/MathML&quot; overflow=&quot;scroll&quot;><mrow><msub><mi>CO</mi><mrow><mn>3</mn></mrow></msub></mrow></math>\"><span class=\"math\"><span><span class=\"mrow\"><span class=\"mrow\"><span class=\"msub\"><span id=\"MathJax-Span-14\" class=\"mi\">CO</span><span class=\"mrow\"><span class=\"mn\"><sub>3</sub>,</span></span></span></span></span></span></span></span></span> <span id=\"MathJax-Element-3-Frame\" class=\"MathJax\" data-mathml=\"<math xmlns=&quot;http://www.w3.org/1998/Math/MathML&quot; overflow=&quot;scroll&quot;><mrow><msup><mi>Fe</mi><mrow><mn>3</mn><mo>+</mo></mrow></msup></mrow></math>\"><span id=\"MathJax-Span-17\" class=\"math\"><span><span id=\"MathJax-Span-18\" class=\"mrow\"><span id=\"MathJax-Span-19\" class=\"mrow\"><span id=\"MathJax-Span-20\" class=\"msup\"><span id=\"MathJax-Span-21\" class=\"mi\">Fe</span><sup><span id=\"MathJax-Span-22\" class=\"mrow\"><span id=\"MathJax-Span-23\" class=\"mn\">3</span><span id=\"MathJax-Span-24\" class=\"mo\">+</span></span></sup></span></span></span></span></span></span><span><span>, and Fe2+ </span></span>absorption features. Analysis of field samples permits suites of minerals causing absorption features to be identified. However, specific mineral identification cannot be achieved consistently using the SMIRR ratio traces or normalized SMIRR spectra, because the Al‐OH and Mg‐OH absorption features can be caused by more than one of the minerals commonly present. The normalized SMIRR spectra are especially useful for identifying subtle Al‐OH and Mg‐OH absorption features that are difficult to identify in the unnormalized ratio traces and for comparing the relative intensities of absorption features. Al‐OH absorption is related to muscovite, smectite, illite, and kaolinite, whereas Mg‐OH absorption is caused by chlorite, amphibole, and biotite. The principal sources of error in using SMIRR spectral measurements for identifying mineral groups along the orbit 27 groundtrack are inaccuracies in field location and lithologic heterogeneity that is not represented adequately by field samples. Calibration errors may account for systematic albedo and absorption intensity differences between calculated laboratory SMIRR spectra and normalized SMIRR spectra. SMIRR instrument noise and atmospheric factors appear to be less important sources of error. However, as higher spectral and spatial resolution systems are developed for mineral identification, radiometric precision and atmospheric factors will become more important.<span></span><br><div><br></div></div>","language":"English","publisher":"Society of Exploration Geophysicists","doi":"10.1190/1.1442361","issn":"00168033","usgsCitation":"Rowan, L.C., Goetz, A., and Abbott, E., 1987, Analysis of Shuttle Multispecral Infrared Radiometer measurements of the western Saudi Arabian shield.: Geophysics, v. 52, no. 7, p. 907-923, https://doi.org/10.1190/1.1442361.","productDescription":"17 p.","startPage":"907","endPage":"923","numberOfPages":"17","costCenters":[],"links":[{"id":225875,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"52","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059eaffe4b0c8380cd48b4b","contributors":{"authors":[{"text":"Rowan, Lawrence C.","contributorId":58629,"corporation":false,"usgs":true,"family":"Rowan","given":"Lawrence","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":367711,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Goetz, Alexander F.H.","contributorId":89805,"corporation":false,"usgs":true,"family":"Goetz","given":"Alexander F.H.","affiliations":[],"preferred":false,"id":367712,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Abbott, Elsa","contributorId":16991,"corporation":false,"usgs":false,"family":"Abbott","given":"Elsa","email":"","affiliations":[{"id":27151,"text":"Jet Propulsion Laboratory, California Institute of Technology, Pasadena, CA, USA","active":true,"usgs":false}],"preferred":false,"id":367710,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

These rocks are assumed to be laterally restrained and are modelled as a homogeneous, orthotropic or transversely isotropic, linearly elastic material. The analysis, constrained by the thermodynamic requirement that strain energy be positive definite, gives the following important result: inclusion of anisotropy broadens the range of permissible values of gravity-induced horizontal stresses. In fact, for some ranges of anisotropic rock properties, it is thermodynamically admissible for gravity-induced horizontal stresses to exceed the vertical stress component; this is not possible for the classical isotropic solution.

These patterns may be caused by large submarine canyons which dominate the physiography of this part of the Bering Sea continental margin.</div></div></div></div></div><div id=\"preview-section-introduction\"><br></div>","language":"English","publisher":"Elsevier","doi":"10.1016/0025-3227(87)90057-0","issn":"00253227","usgsCitation":"Karl, H.A., and Carlson, P., 1987, Surface current patterns suggested by suspended sediment distribution over the outer continental margin, Bering Sea: Marine Geology, v. 74, no. 3-4, p. 301-308, https://doi.org/10.1016/0025-3227(87)90057-0.","productDescription":"8 p.","startPage":"301","endPage":"308","numberOfPages":"8","costCenters":[],"links":[{"id":225266,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"74","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9f9ee4b08c986b31e707","contributors":{"authors":[{"text":"Karl, Herman A.","contributorId":80649,"corporation":false,"usgs":true,"family":"Karl","given":"Herman","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":368861,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Carlson, P.R.","contributorId":97055,"corporation":false,"usgs":true,"family":"Carlson","given":"P.R.","email":"","affiliations":[],"preferred":false,"id":368862,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The phenocrysts present are abundant plagioclase, less abundant olivine ± spinel, and traces of sulfide. Clinopyroxene is absent in the glasses. The mineral chemistry is typical of ocean floor basalt. However, unusually anorthitic plagioclase in some highly plagioclasephyric samples, complex zoning in plagioclase and olivine, and other disequilibrium features indicate complex petrogenetic processes involving magma mixing. Glass inclusions in olivine and plagioclase indicate primitive trapped melts. The chemical diversity of Gorda Ridge lava appears to have been primarily caused by variable degrees of partial melting, but crystal fractionation and magma mixing were also important processes. Compositional variations along the strike of the ridge indicate that lava from the segment south of the offset at latitude 41.6°N was generated by the smallest percentage of partial melting of a source less depleted than that of the two northern segments. Lava from the central and northern segments was generated by variable percentages of partial melting of a uniformly depleted source. Lava from the northern segment shows the greatest diversity with a large range in percentage of melting and both relatively primitive and evolved compositions in spatially and temporally closely associated lava. The diversity of lava from the northern segment may result from thermal perturbations caused by proximity to the Blanco Fracture Zone. Gorda Ridge lava is more similar to that from the Mid-Atlantic Ridge at 22°–25°N than to that from other spreading centers in the Pacific Ocean. Magma chambers under the Gorda Ridge appear to be small, discontinuous in time and space and possibly at greater depth than those beneath other Pacific spreading centers.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB092iB10p10467","issn":"01480227","usgsCitation":"Davis, A.S., and Clague, D., 1987, Geochemistry, mineralogy, and petrogenesis of basalt from the Gorda Ridge: Journal of Geophysical Research Solid Earth, v. 92, no.

However, average water velocities during floods are high (as much as 23 ft/sec) and the channel, banks, and some dikes are composed of unstable materials. Sunshine Point campground is particularly susceptible to flooding and damage from Tahoma Creek, and to a lesser extent from the Nisqually River, if large amounts of debris or rock material accumulate in the channels and change the flood elevation or courses of either stream. At Longmire flood inundation or damage from the Nisqually River is much less, but flooding is still possible. There, high ridges upstream protect the several park facilities from the river, but accumulations of debris or rock in the channel could cause flooding from overtopping of dikes or riverbanks. Glacial outburst floods are a matter of serious concern at both Sunshine Point campground and Longmire. Glacial outbursts can and have produced very large flood discharges and transported large quantities of debris and rock materials. Although none have been known to transport these materials from Tahoma Glacier as far as Sunshine Point campground, one in 1955 from Nisqually Glacier (estimated at 70,000 cu ft/sec near the glacier) did appreciably increase the magnitude of the water discharge at Longmire. For safety, campers and visitors need to be advised about the potential flood hazards at both facilities.&nbsp;</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri864179","usgsCitation":"Nelson, L.M., 1987, Flood characteristics for the Nisqually River and susceptibility of Sunshine Point and Longmire facilities to flooding in Mount Rainier National Park, Washington: U.S. Geological Survey Water-Resources Investigations Report 86-4179, Report: iv, 18 p.; 20.74 x 12.38 inches and 16.40 x 12.63 inches, https://doi.org/10.3133/wri864179.","productDescription":"Report: iv, 18 p.; 20.74 x 12.38 inches and 16.40 x 12.63 inches","costCenters":[],"links":[{"id":124120,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1986/4179/report-thumb.jpg"},{"id":415522,"rank":5,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_36604.htm","linkFileType":{"id":5,"text":"html"}},{"id":57744,"rank":4,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/1986/4179/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":57745,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1986/4179/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":57743,"rank":3,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/1986/4179/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Washington","otherGeospatial":"Mount Rainier National Park, Nisqually river","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -121.922,\n              46.753\n            ],\n            [\n              -121.922,\n              46.733\n            ],\n            [\n              -121.808,\n              46.733\n            ],\n            [\n              -121.808,\n              46.753\n            ],\n            [\n              -121.922,\n              46.753\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49d5e4b07f02db5ddba9","contributors":{"authors":[{"text":"Nelson, L.

Sulfate-deposition rates in bulk sampling in New York during 1965-80 were approximately 40% of the average sulfur-emission rate for the Northeast. Sulfate-deposition rates in bulk and wetfall collectors were nearly equal and were five times greater than in the dryfall collector. Scavenging ratios for sulfate averaged 8.9 ?? 105; those for sulfate plus sulfur dioxide averaged 4.6 ?? 105. Sulfate concentrations in wet deposition averaged more than twice those estimated from published regional-scale washout equations, whereas those in dry deposition averaged only 22% of those computed from deposition velocities of 0.1 cm/s for sulfate and 1.0 cm/s for sulfur dioxide. Discrepancies in the dryfalls are attributed to inefficiency of dryfall-collection equipment. -from Author","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Northeastern Environmental Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Barnes, C., 1987, Relation of long- and short-term atmospheric sulfur concentrations to sulfate deposition in New York State: Northeastern Environmental Science, v. 6, no. 2, p. 89-98.","startPage":"89","endPage":"98","numberOfPages":"10","costCenters":[],"links":[{"id":225666,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"6","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50e4a693e4b0e8fec6cdc20d","contributors":{"authors":[{"text":"Barnes, C.R.","contributorId":85625,"corporation":false,"usgs":true,"family":"Barnes","given":"C.R.","email":"","affiliations":[],"preferred":false,"id":369451,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Box core samples and bottom photographs collected across the oxygen minimum zone of the coastal upwelling system were analyzed for lithologic and biologic trends. Three major OMZ facies are identified, along the upper and lower edges of the OMZ and one at its core. The upper boundary (525 m) of the central California OMZ (&lt; 0.5 ml/liter O<span>&nbsp;</span><sub>2</sub><span>&nbsp;</span>) is characterized by glauconitic gravelly sands relatively depleted in detrital silicates and enriched in carbonate and total organic carbon (TOC). These upper-boundary sands also have a maximum macrofauna density and a high abundance of foraminiferal fragments (&gt; 80% of total forams) with Cassidulina the dominant benthic foraminifer. With increasing water depth, decreasing current speed, and dissolved oxygen content toward the core of the OMZ (750 m), grain size, glauconite, carbonate, TOC, and foraminiferal fragments all decrease as the abundance of mica and detrital silicates increase. The greatest number of genera of benthic foraminifera occurs at the core of the OMZ where their relative concentration is at a minimum and Bolivina is the dominant genus. No heavily calcified macrofauna were found at the core of the OMZ; however, near-surface sediments are highly bioturbated. As the lower boundary (1,025 m) of the OMZ is approached, grain size and abundance of detrital silicates continue to decrease as glauconite disappears. Concomitantly, the relative abundance of mica, carbonate, TOC, siliceous microfauna, benthic foraminifers, and foram fragments increase. The benthic foraminifer population consists largely (&gt; 40%) of Globobulimina and Praeglobobulimina . The lower edge of the OMZ is highlighted by a distinct peak of fecal pellets (25% of sand-size material). Lithofacies and biofacies associated with the OMZ are controlled by an interplay of oceanic circulation, dissolved oxygen concentrations, and possibly by increased biological activity within the OMZ edge environment and slight changes in the slope gradient. Recognition of key lithofacies and biofacies trends may prove to be powerful paleoenvironmental/paleoceanographic indicators and may be useful in identifying ancient zones of upwelling analogous to the modern central California system where phosphorites, organic-rich shales, and/or chert are absent.</p></div></div>","language":"English","publisher":"SEPM","doi":"10.1306/212F8BE8-2B24-11D7-8648000102C1865D","issn":"00224472","usgsCitation":"Vercoutere, T., Mullins, H., McDougall, K., and Thompson, J., 1987, Sedimentation across the central California oxygen minimum zone: an alternative coastal upwelling sequence: Journal of Sedimentary Petrology, v. 57, no. 4, p. 709-722, https://doi.org/10.1306/212F8BE8-2B24-11D7-8648000102C1865D.","productDescription":"14 p.","startPage":"709","endPage":"722","numberOfPages":"14","costCenters":[],"links":[{"id":225820,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"57","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8a4de4b08c986b317124","contributors":{"authors":[{"text":"Vercoutere, T.

In response to an allegation that rotenone might cause mammary tumors, the U.S. Environmental Protection Agency, in 1976, announced that it was considering listing rotenone as an unsafe substance. To determine if these allegations were correct, the U.S. Fish and Wildlife Service, in concert with the International Association of Fish and Wildlife Agencies, embarked on an extensive research effort. The project was funded in part with Federal Aid in Sport Fish Restoration administrative funds, extended over 6 years, and cost nearly $3,000,000.

These projections are intended as guidelines for Great Lakes resource managers and scientists. Attainment of projected yields depends on restoration of stable fish communities containing some large piscivores that will use prey efficiently, continuation of control of the sea lamprey (Petromyzon marinus), and restoration of high-quality fish habitat. Because Great Lakes fish communities were harmonic before their collapse, we used their historic yield properties as part of the basis for projecting potential yields of rehabilitated communities. This use is qualified, however, because of possible inaccuracies in the wholly commercial yield data, the presence now of greatly expanded sport fisheries that affect yield composition and magnitude, and some possibly irreversible changes since the 1950s in the various fish communities themselves. We predict that total yields from Lakes Superior, Huron, and Ontario will be increased through rehabilitation, while those from Lakes Michigan and Erie will decline. Salmonines and coregonines will dominate future yields from the upper lakes. The Lake Erie fishery will continue to yield mostly rainbow smelt (Osmerus mordax), but the relative importance of percids, especially of walleye (Stizostedion vitreum vitreum) will increase. In Lake Ontario, yields of salmonines will be increased. Managers will have to apply the most rigorous management strictures to major predator species.</p>","language":"English","publisher":"NRC Research Press","doi":"10.1139/f87-343","usgsCitation":"Loftus, D., Olver, C., Brown, E., Colby, P., Hartman, W.L., and Schupp, D., 1987, Partitioning potential fish yields from the Great Lakes: Canadian Journal of Fisheries and Aquatic Sciences, v. 44, no.
