The Newcombe method, a simple procedure developed in British Columbia that is based on the distribution of water depths and velocities at various flows, was used to predict usable habitat at seven flows. Predicted usable habitat was two to six times greater for rainbow trout than for any of the other species at all flows. Angler harvest corresponded to the predicted abundance for rainbow trout and smallmouth bass, but the catch of channel catfish and white crappies was seasonally greater than expected. The presence of the dam and reservoir apparently disrupted the normal movement and feeding patterns of these species and periodically overrode the relation between usable habitat and abundance assumed in the Newcombe method. The year-round minimum flow of 4.6 m 3/s recommended for the tailwater would generally increase the amount of habitat available in the tailwater from April through October, and the minimum flow of 2.4 m3/s recommended for periods of drought would allow the maintenance of a trout fishery.</p>","language":"English","publisher":"American Fisheries Society","doi":"10.1577/1548-8659(1987)7<569:MTFIRT>2.0.CO;2","usgsCitation":"Jacobs, K., Swink, W., and Novotny, J., 1987, Minimum tailwater flows in relation to habitat suitability and sport-fish harvest: North American Journal of Fisheries Management, v. 7, no. 4, p. 569-574, https://doi.org/10.1577/1548-8659(1987)7<569:MTFIRT>2.0.CO;2.","productDescription":"6 p.","startPage":"569","endPage":"574","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true},{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"links":[{"id":134217,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Kentucky","otherGeospatial":"Green River Lake","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -85.44685363769531,\n              37.12857106113289\n            ],\n            [\n              -85.44685363769531,\n              37.37670527881838\n            ],\n            [\n              -85.10833740234374,\n              37.37670527881838\n            ],\n            [\n              -85.10833740234374,\n              37.12857106113289\n            ],\n            [\n              -85.44685363769531,\n              37.12857106113289\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"7","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db699d08","contributors":{"authors":[{"text":"Jacobs, K.E.","contributorId":57813,"corporation":false,"usgs":true,"family":"Jacobs","given":"K.E.","email":"","affiliations":[],"preferred":false,"id":313305,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Swink, W.D.","contributorId":66200,"corporation":false,"usgs":true,"family":"Swink","given":"W.D.","affiliations":[],"preferred":false,"id":313306,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Novotny, J.F.","contributorId":95856,"corporation":false,"usgs":true,"family":"Novotny","given":"J.F.","email":"","affiliations":[],"preferred":false,"id":313307,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Soil excavation rate, measured in terms of either daily additions to tunnel length or volume, or the maximum volume excavated during a 3—d interval, varied greatly among individuals. No significant effect due to season or density of belowground plant biomass was detected when burrowing was profitable. Individuals readily initiated aboveground travel in unprofitable treatments. Soil bulk density was negatively related and animal body mass positively related to excavation rate. Individuals deposited from 41 to 87% of excavated soil on the ground surface; the remainder was used to backfill previously created tunnels or chambers. Plant size, but not plant spacing, affected the ratio of the volumes deposited aboveground and belowground. There was no evidence that animals in enclosures disturbed soil in a manner quantitatively or qualitatively different from free—ranging adults.

Urinary sodium (na) and potassium (K) were diminished in fasted deer after 2 and 4 weeks. Renal excretion of Na and K were lower, whereas urinary phosphorus (P) was higher in fasted deer compared to deer fed high protein-high energy (HPHE) diets. Urinary P excretion of the fasted deer was also greater than in a low protein-high energy (LPHE)-fed group. Urinary area excretion of fasted deer was similar to that of deer fed low and high protein diets.

Even within a single, continuous, linear spreading-ridge segment with relatively uniform axial valley dimensions over a distance of 50 or more kilometers, such as along the southern Juan de Fuca Ridge, the changes in morphometric characteristics along axis within the youngest crust indicate distinct variation in tectonic and volcanic activity over short distances within short time periods. An integrated analysis of Sea MARC I, Sea MARC II, and photographic data for the southernmost continuous segment of the Juan de Fuca Ridge shows that generalizations about tectonic and volcanic processes at spreading ridges must consider both the temporal scale of processes as well as the physical scales of observations if predictive models are to be successful. Comparison of the morphometric expression within the major hydrothermal vent area and the rest of the southernmost ridge segment suggests that the mapped distribution of hydrothermal vents may reflect the extent of survey effort rather than uniqueness of geologic setting.</span></p>","language":"English","publisher":"AGU Publications","doi":"10.1029/JB092iB11p11291","usgsCitation":"Kappel, E.S., and Normark, W.R., 1987, Morphometric variability within the axial zone of the southern Juan de Fuca Ridge: Interpretation from Sea MARC II, Sea MARC I, and deep-sea photography: Journal of Geophysical Research B: Solid Earth, v. 92, no.

The mathematical modeling analysis presented in this paper demonstrates for gasoline-range hydrocarbons, and other volatile organics commonly spilled, that diffusive transport in the unsaturated zone is a significant transport mechanism which can cause aqueous and vapor plumes to spread away from the immiscible liquid source, resulting in increasing groundwater contaminating potential. An analytical solution to a one-dimensional version of the transport model allows for the definition of a retardation coefficient which is dependent on phase-partitioning coefficients and moisture content. Significant differences in migration rates should be anticipated between hydrocarbons. A numerical solution was developed for a radially symmetric version of the model defining transport for a multiconstituent contaminant like gasoline. Differences in anticipated migration rates between aromatic and nonaromatic hydrocarbons was clearly demonstrated. A simulation based on the composition of an actual gasoline revealed that aromatic constituents, although constituting a fraction of the initial gasoline composition, completely defined the groundwater contaminating potential. This potential changes in time as constituents are selectively removed from the unsaturated zone. Further, the groundwater contaminating potential is quite sensitive to the ground surface boundary characterization.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/WR023i010p01926","usgsCitation":"Baehr, A.L., 1987, Selective transport of hydrocarbons in the unsaturated zone due to aqueous and vapor phase partitioning: Water Resources Research, v. 23, no. 10, p. 1926-1938, https://doi.org/10.1029/WR023i010p01926.","productDescription":"13 p.

Hatchlings remained together in sibling groups (pods) for at least their 1st year and then began to disperse during their 2nd spring and summer. Mortality through mid-November of their 1st year was negligible. Jolly-Seber (JS) survival estimates of hatchlings for 6 and 12 months were 76 and 41%, respectively. The 2-year JS estimate for the 1980 cohort was 8%. Minimum-Known-Alive (MKA) survival values were 72 and 46% of JS estimates for 6 months and 1 year of age.

Fasting effects were also observed for hemoglobin (Hb), red blood cell (RBC) counts, packed cell volume (PCV), cholesterol, triglycerides, serum urea nitrogen (SUN), potassium (K), glucose, phosphorus (P), insulin, thyroxine (T4), and total protein (TP). Refeeding influenced cholesterol, sodium (Na), and calcium (Ca). Hemoglobin, PCV, Ca, P, and albumin varied with time in fasted deer.

At 1 site, the Rob and Bessie Welder Wildlife Refuge (WWR), turkeys have declined precipitously in recent years. During the winters of 1983-85, 442 wild turkeys were caught with cannon and drop nets, 161 of these on WWR. Blood samples were drawn for serologic evaluation, and cloacal and tracheal swabs were collected for isolation attempts. Salmonella spp. bacteria, Newcastle disease virus (NDV), and avian influenza virus (AIV) were not detected in any samples tested. Serologic tests for antibodies to NDV and AIV also were negative. Many mycoplasma isolates were recovered from turkeys from every location. Characterization of these isolates indicated that several species were present. None were species typically associated with mycoplasmosis in domestic turkeys, such as <i>Mycoplasma gallisepticum</i> (MG), <i>M. meleagridis</i> (MM), or <i>M. synoviae</i> (MS), although antibodies to these pathogens were detected in turkeys at every location sampled.

Two profiles are normal to the strike of the spreading center and intersect the ridge at latitude 44°40′N and 45°05′N; a third profile extends south along the ridge axis from latitude 45°20′N and crosses the Blanco Fracture Zone. Processing of the axial portions of the cross-strike lines resolved a weak reflection centered beneath the axis. The reflector is at a depth similar to seismically detected magma chambers on the East Pacific Rise and a Lau Basin spreading center; we suggest that the reflector represents the top of an axial magma chamber. In the migrated sections the top of the probable magma chamber is relatively flat and 1–2 km wide, and the subbottom depth of the chamber is greater where the depth to the ridge axis is greater.</span></p>","language":"English","publisher":"AGU Publications","doi":"10.1029/JB092iB11p11315","usgsCitation":"Morton, J.L., Sleep, N.H., Normark, W.R., and Tompkins, D.H., 1987, Structure of the southern Juan de Fuca Ridge from seismic reflection records: Journal of Geophysical Research B: Solid Earth, v. 92, no.

(fig. C-l), resulted in the release of 1.5x10<sup>5</sup> L (liters) of crude oil. Although about 1.1x10<sup>5</sup>&nbsp;L were removed from the site as part of the cleanup, some crude oil infiltrated the ground and percolated to the water table. The spill occurred in the recharge area of a local flow system that discharges to a small lake 300 m (meters) downgradient (Hult, 1984).</p>\n<p>The aquifer is a pitted and dissected outwash plain underlain at a depth of about 20 m by low-permeability till. Crude oil is floating on the water table about 8 m below land surface and has migrated about 20 m as a separate fluid phase. Soluble petroleum derivatives have dissolved in and are moving with ground water. Volatile constituents are migrating through the unsaturated zone by diffusion.</p>\n<p>The abstracts presented in this chapter provide an overview of ongoing efforts to combine the results of interdependent, interdisciplinary research into the comprehensive understanding of the physical, chemical, and biological processes that will be needed to develop predictive models of contaminant mobilization, transport, and fate.</p>\n<p>Franzi investigates the relationship between depositional and post-depositional processes and the heterogeneity and anisotropy of the aquifer. Post-depositional subsidence and collapse caused by melting of stagnant ice has created significant geomorphic and hydrogeologic structures. Miller describes a preliminary ground-water flow and chemical-transport model used to assess the effect of these hydrologic discontinuities, estimate aquifer properties, and to guide continuing field work.</p>\n<p>Abstracts by Siegel, Bennett, and Berndt describe studies of dissolved inorganic constituents and parameters done to characterize the geochemical environments in and around the site. An anoxic zone, probably plume shaped, extends downgradient of the oil pool and into an oxic zone that surrounds the contamination. Carbonate minerals are actively dissolving in the oxic spray zone upgradient of the oil pool where oil is being mineralized, whereas quartz is dissolving underneath the oil by organic-acid complexation.</p>\n<p>Selective leaching experiments show that fractionation of metals is also occurring where the aquifer matrix is contaminated. Morphological analysis of quartz sand grains clearly show unusual rock-water interactions are occurring in the anaerobic contaminant zone. Preliminary analysis indicates the possibility of an organic/quartz interaction that is significantly increasing the mobility of silica through the system.</p>\n<p>Predictions of the evolution and ultimate geometry of contaminant plumes resulting from spills require quantitative descriptions of the rate of mass transfer from the organic fluid to ground water. Pfannkuch presents laboratory and field work that describe how the the rate of oil dissolution, and therefore the strength of the contaminant source, is controlled by fluctuations in ground-water velocity and water-table fluctuations.</p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"U.S. Geological Survey program on toxic waste--ground-water contamination: Proceedings of the Third technical meeting, Pensacola, Florida, March 23-27, 1987","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Tallahassee, FL","doi":"10.3133/ofr87109C","usgsCitation":"Hult, M.F., 1987, Movement and fate of crude-oil in contaminants in the subsurface environment at Bemidji, Minnesota: Chapter C in <i>U.S. Geological Survey program on toxic waste--ground-water contamination: Proceedings of the Third technical meeting, Pensacola, Florida, March 23-27, 1987</i>: U.S. Geological Survey Open-File Report 87-109, 39 p., https://doi.org/10.3133/ofr87109C.","productDescription":"39 p.","startPage":"C1","endPage":"C39","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":392,"text":"Minnesota Water Science Center","active":true,"usgs":true}],"links":[{"id":326466,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"country":"United States","state":"Minnesota","city":"Bemidji","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"57aef346e4b0fc09faae03dd","contributors":{"authors":[{"text":"Hult, Marc F.","contributorId":18344,"corporation":false,"usgs":true,"family":"Hult","given":"Marc","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":645391,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

This is the first successful prediction of an earthquake along the San Andreas fault, and the probability to have come true by chance is &lt;5%. Although the prediction addressed only a small main-shock, its success was significant because the location, size and occurrence time were correctly specified for an earthquake in a populated area. Larger earthquakes will undoubtedly be successfully predicted by the same method in the future, but the major segments of the San Andreas fault near San Francisco and Los Angeles have such a low-background seismicity rate that the method will probably not be applicable there.</span></p>","language":"English","publisher":"Springer Nature","doi":"10.1038/329323a0","issn":"00280836","usgsCitation":"Wyss, M., and Burford, R.O., 1987, Occurrence of a predicted earthquake on the San Andreas fault: Nature, v. 329, no. 6137, p. 323-325, https://doi.org/10.1038/329323a0.","productDescription":"3 p.","startPage":"323","endPage":"325","costCenters":[],"links":[{"id":225300,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"San Andreas fault","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -122.41270853437362,\n              38.58374493659562\n            ],\n            [\n              -120.30965300424211,\n              35.82477957032963\n            ],\n            [\n              -118.36376530215928,\n              33.77772377477025\n            ],\n            [\n              -117.15340132995125,\n              32.856861547556186\n            ],\n            [\n              -116.46278570150008,\n              33.17453973179309\n            ],\n            [\n              -120.1308486362434,\n              38.792139471708424\n            ],\n            [\n              -122.41270853437362,\n              38.58374493659562\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"329","issue":"6137","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a6bc6e4b0c8380cd7489a","contributors":{"authors":[{"text":"Wyss, M.","contributorId":68880,"corporation":false,"usgs":true,"family":"Wyss","given":"M.","email":"","affiliations":[],"preferred":false,"id":367771,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Burford, Robert O.","contributorId":52560,"corporation":false,"usgs":true,"family":"Burford","given":"Robert","middleInitial":"O.","affiliations":[],"preferred":false,"id":367770,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The main feature of interest in the geophysical data is a broad high-conductivity anomaly mapped with MT and geomagnetic variation (GMV) data. This anomaly is located roughly within the triangle formed by the volcanoes Mount Rainier, Mount St. Helens, and Mount Adams but exceeds beyond Mount Rainier to the northwest. We interpret the cause of the anomaly to be conductive rocks with resistivities of 1–4 ohm m and thicknesses possibly greater than 15 km. These conductive rocks are found 2–8 km beneath the overlying less conductive volcanic and sedimentary rocks at the surface. Two aeromagnetic lows follow the trend of the conductivity anomaly, and linear belts of strike-slip seismicity are coincident with both these magnetic lows. One of the aeromagnetic lows is coincident with the western margin of the conductivity anomaly. The geophysical data appear to outline a suture zone of probable Eocene age caused by accretion of a large seamount complex (Siletzia) and that may contain large thicknesses of compressed forearc basin and accretionary prism sedimentary rocks of Cretaceous to Eocene age. Part of the shallower conductive rocks may be associated with carbonaceous continental and transitional marine sedimentary rocks of the Puget Group. The contact between the hypothesized compressed basin and the accreted terranes to the west may localize the release of shear stresses in this region of oblique subduction. Several possible explanations for the conductivity anomaly are considered in addition to the compressed basin hypothesis.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB092iB10p10179","usgsCitation":"Stanley, W., Finn, C.A., and Plesha, J.L., 1987, Tectonics and conductivity structures in the Southern Washington Cascades: Journal of Geophysical Research B: Solid Earth, v. 92, no.

The complex is roughly 5–6 km thick and has apparently intruded a buried and compressed Mesozoic forearc sedimentary sequence. The lateral extent of the intrusive complex is uncertain, and we give three alternative models varying from about 18 by 10 km to as much as 18 by 22 km. The western boundary of the inferred Mount St. Helens intrusion abuts several of a number of Tertiary and younger plutons that crop out in the area. The Mount St. Helens intrusion apparently is adjacent to sedimentary rock or shallow volcanic rock along most of the remainder of its boundary. A ringlike drainage pattern around Mount St. Helens suggests subsidence caused by removing magma from deep beneath Mount St. Helens and adding this mass to the Mount St. Helens edifice and its underlying intrusion.
