Below a sub-bottom depth of about 25 m, sedi ment cores commonly contained pockets caused by the expansion of gas upon core recovery. The carbon isotopic com position (δ13C %0 relative to PDB standard) of CH4 and CO2 in these gas pockets has been measured, resulting in the following observations: (1) δ 1 3CC H 4 values increase with depth from approximately -94% in the uppermost sediment to about -66% in the deepest sediment, reflecting a systematic but nonlinear depletion of 12C with depth. (2) δ 1 3Cc θ 2 values also increase with depth of sediment from about - 25% to about - 4%, snowing a depletion of 12C that closely parallels the trend of the isotopic composition of CH4 . The magnitude and parallel distribution of δ 13C values for both CH4 and CO2 are consistent with the concept that the formation of the CH4 resulted from the microbiological reduction of CO2 from organic substances. These results imply that CH4 and CO2 incorporated in gas hydrates at this site are biogenic.</p><p><br data-mce-bogus=\"1\"></p>","language":"English","publisher":" PANGAEA - Data Publisher for Earth & Environmental Science","doi":"10.2973/dsdp.proc.76.110.1983","usgsCitation":"Galimov, E., and Kvenvolden, K.A., 1983, Concentrations and carbon isotopic compositions of CH4 and CO2 in gas from sediments of the Blake Outer Ridge, Deep Sea Drilling Project Leg 76: Initial Reports of the D.S.D.P., v. 76, p. 403-407, https://doi.org/10.2973/dsdp.proc.76.110.1983.","productDescription":"5 p.","startPage":"403","endPage":"407","costCenters":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":488891,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"http://doi.org/10.2973/dsdp.proc.76.110.1983","text":"Publisher Index Page"},{"id":372073,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"The Blake Outer Ridge, Site 533, Leg 76, and Sites 102, 103, and 104, Leg ","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -81.6943359375,\n              29.132970130878636\n            ],\n            [\n              -72.04833984375,\n              29.132970130878636\n            ],\n            [\n              -72.04833984375,\n              33.99802726234877\n            ],\n            [\n              -81.6943359375,\n              33.99802726234877\n            ],\n            [\n              -81.6943359375,\n              29.132970130878636\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"76","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Galimov, E.M.","contributorId":222242,"corporation":false,"usgs":false,"family":"Galimov","given":"E.M.","email":"","affiliations":[],"preferred":false,"id":781616,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kvenvolden, Keith A. kkvenvolden@usgs.gov","contributorId":3384,"corporation":false,"usgs":true,"family":"Kvenvolden","given":"Keith","email":"kkvenvolden@usgs.gov","middleInitial":"A.","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":781617,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The Arizona study area was selected for the application of the guilding technology because a thorough assessment of the floral and faunal resources had recently occurred in conjunction with the development of a grazing Environmental Impact Statement (EIS).  Thus, the association of wildlife species with habitat type was well known, which aided in the compilation of the data base necessary for the development of guilds.  Some data were also available that described the vegetative structure of habitats.

The profile is measured as the sled is towed along the shore-normal transect using an infrared rangefinder mounted landward of the winch and optical prisms mounted on top of the sled's mast. A pressure sensor and two-axis electromagnetic current meter are mounted on the frame of the sled. These data are encoded on the sled and telemetered to a receiving/recording station onshore.

Geochemical, artesian pressure, and water temperature data show that the source of the relatively high concentrations of chloride in water in the upper part of the aquifer is from the deeper zone.

Constant displacement rate tests on 70 samples of pure polycrystalline water ice have been performed at temperatures 77≤≤258 K, confining pressures 0.1≤≤350 MPa, and strain rates 3.5×10≤ ≤3.5×10 s. In most cases, the ice polymorph tested was ice . Both brittle and ductile behavior have been observed. Brittle behavior of ice, promoted by lower pressure, lower temperature, and higher strain rate, is analogous to that in rocks, with the important exception that brittle fracture strength becomes independent of confining pressure above 50 MPa pressure and the fracture angle is approximately 45° to the loading direction (i.e., the coefficient of internal friction is approximately zero). Ductile flow, the predominant behavior in our tests at ≥195 K, follows a law of form = σ exp (−*/) (σ is stress; is the gas constant; , * are material constants). Three sets of material constants are required to fit the data, with changes in sets (or mechanisms) occurring near 243 K and 195 K. The value of remains near 4 throughout the measured ductile field, but * drops from 91 to 61 to 31 /mole as temperature decreases. The maximum brittle strength measured was 171 MPa; the maximum ductile strength measured was 91 MPa. At confining pressures near the phase transition pressure of ice → ice II, the ductile strength is observed to drop dramatically. Some overlap with previous work occurs at higher temperatures and lower pressures. Agreement with present work is generally good, both quantitatively in the values of and *, and qualitatively in the mechanism of deformation. Although the ductile strengths measured here are somewhat higher than expected on the basis of extrapolations of previous work, the low value of * at &lt;195 K indicates that the ice layer on icy bodies in the solar system is much weaker than has generally been predicted.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB088iS01p0B377","usgsCitation":"Durham, W., Heard, H.C., and Kirby, S.H., 1983, Experimental deformation of polycrystalline H2O ice at high pressure and low temperature: Preliminary results: Journal of Geophysical Research B: Solid Earth, v. 88, p.

Hess Rise apparently formed in the Southern Hemisphere along the western flank of the Pacific-Farallon Ridge 110 to 100 m.y. B.P. Core stratigraphies and lithologies show the response of sedimentation to subsidence and northward movement of Hess Rise on the Pacific plate. Oceanic islands, which crowned Hess Rise during its early evolution, were eroded and subsequently subsided below sea level.</p><p>Major structural trends include three northwest-trending (∼327°) arms, or ridges, and an east-northeast-trending southern Hess Rise that parallels the Mendocino Fracture Zone (060°). Normal faults offset basement as much as 3,000 m along the southern edge and 1,500 m on the western flank of Hess Rise. Many faults were active during sedimentation.</p><p>Tholeiitic basalt from the base of Hole 464, trachyte from the base of Hole 465A, and alkalic basalt clasts within sediment of Hole 466 show the diversity of rock types that constitute the igneous basement. A major rock unit is middle Cretaceous limestone, chalk, and minor chert that form the basal sedimentary unit. Some limestone samples, rich in organic carbon, reflect accumulation above the carbonate compensation depth (CCD) within a mid-water oxygen minimum zone. The organic-carbon-rich sediments probably were deposited on the submarine slopes of islands and banks that were at upper bathyal depths as Hess Rise crossed the wide equatorial divergence where increased upwelling and biogenic productivity contributed to high accumulation rates. The source of organic matter was mostly lipid-rich, autochthonous, marine organic matter.</p><p>Analyses of sediment samples from across the Cretaceous-Tertiary boundary at Site 465 show that there was a significant decrease in surface water temperature and biological productivity.

The time of ‘docking’ of the terranes against cratonic Alaska is critical to defining their amalgamated size and extent during their northward motion as well as their role in the evolution of the Bering Sea. One of the largest of the tectonostratigraphic terranes, the Peninsular terrane of south central and southwestern Alaska, extends offshore along the outer Bering Sea continental margin (Beringia). Paleomagnetic data suggest that this terrane has moved northward through all of Cenozoic time, but geologic data imply that the terrane had accreted to Alaska by the end of the Mesozoic. In early Cenozoic time the eastern part of the Aleutian arc appears to have been superimposed on the Peninsular terrane, and postulated northward Cenozoic motion of the terrane would therefore have required northward motion of the arc. Two accretion models, based on docking times for terranes in Alaska, are proposed, and they illustrate that large areas of the abyssal Bering Sea, the Alaska Peninsula, the Aleutian arc, and the Beringian continental margin may be part of a superterrane or microplate called Aleutia (microplate as defined by Beck et al. (1980), i.e., a microplate is a displaced segment of lithosphere that has crustal roots, whereas a superterrane is an amalgamation of terranes which may or may not be rootless). Model A implies that the Aleutian arc developed in situ on the southern edge of Aleutia after the microplate had docked. In model B, the final docking time of the Peninsular terrane is late Cenozoic, which implies that the Aleutia microplate encompasses a mammoth area that includes parts of southern Alaska, the Alaska Peninsula, the southern Beringian margin, the abyssal Bering Sea (Kula plate), and the Aleutian arc. If model A is correct, the docking time of the Peninsular terrane is late Mesozoic or earliest Tertiary. The Aleutia microplate in this model is made up solely of the abyssal Bering Sea (Kula plate), which presumably docked at the same time or slightly after the Peninsular terrane accreted against Alaska. If model B is correct, that is, if the Aleutia collided with nuclear Alaska during the Cenozoic, then a late Cenozoic suture zone, the vestige of a large open sea that must have closed between Aleutia and Alaska, must exist in south central and southwest Alaska. Either evidence for Cenozoic closure and suturing has been obliterated in Alaska or the inferences of Cenozoic terrane motion derived from paleomagnetic data are suspect.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB088iB04p03439","usgsCitation":"Marlow, M.S., and Cooper, A.K., 1983, Wandering terranes in southern Alaska: The Aleutia Microplate and implications for the Bering Sea: Journal of Geophysical Research B: Solid Earth, v. 88, no.

Abundance of yellow perch was above the 1971-79 average in 1971 and 1972, below average in 1979, and about average or in doubt in the other years. Abundance during 1976-79 was greatest at Saugatuck and decreased more or less progressively from Saugatuck southward and around the southern end of the lake. The geographical differences in abundance were attributable partly to differences in fishing mortality. Average lengths of fish caught were greatest at Saugatuck, and generally greater in Michigan waters than in other areas; they were greater for females than for males. Fish sampled ranged in age from I to IX, but 88% of the males and 81% of the females were of ages II-V. Older perch were generally more common in State of Michigan waters, particularly at Saugatuck, than elsewhere. Females grew faster than males after the second year of life. Average lengths of males and females at the end of 3 years were 197 and 214 mm, respectively, in Michigan waters and 186 and 195 mm in Indiana-Illinois (few perch were caught in Wisconsin). The relation of weight (W) to length (L) for combined sexes was W = 2.6761(10-6) x L3.2644. Perch in southeastern Lake Michigan spawned mainly from late May to mid June. Virtually all males were mature in their second year, but some females not until their fourth year. Perch 174 to 355 mm long contained 9, 300 to 136, 000 eggs. Approximate mortalities of males and females in Michigan waters were 52% and 48%, respectively; rates were higher in Indiana-Illinois.","language":"English","publisher":"U.S. Fish and Wildlife Service","usgsCitation":"Wells, L., and Jorgenson, S.C., 1983, Population biology of yellow perch in southern Lake Michigan, 1971-79: Technical Paper 109, 19 p.","productDescription":"19 p.","numberOfPages":"19","temporalStart":"1979-01-01","temporalEnd":"1979-12-31","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":287831,"type":{"id":15,"text":"Index Page"},"url":"https://www.glsc.usgs.gov/publications/1983/591"},{"id":287832,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"Lake Michigan","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -88.0434,41.6089 ], [ -88.0434,46.1024 ], [ -84.7385,46.1024 ], [ -84.7385,41.6089 ], [ -88.0434,41.6089 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5388570ce4b0318b93124af5","contributors":{"authors":[{"text":"Wells, LaRue","contributorId":75476,"corporation":false,"usgs":true,"family":"Wells","given":"LaRue","email":"","affiliations":[],"preferred":false,"id":354597,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jorgenson, Sherrell C.","contributorId":15934,"corporation":false,"usgs":true,"family":"Jorgenson","given":"Sherrell","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":354596,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

First, eagles used intra- and interspecific local enhancement to locate food. Second, the time that eagles spent aerially searching for food, as indicated by the percentage of eagles flying or soaring, was negatively correlated with relative food availability. Third, eagles often followed others when departing from or arriving at communal night roosts. Following was most frequent when all food was eliminated by flood waters, suggesting a possible food-location function of this behavior.

Sumner and J. J. Craighead, unpubl. rep., Montant Coop. Wildl. Res. Unit, Univ. Montana, Missoula, 1973).  Similar nuts from limber pine are eaten by grizzly bears on the east Rocky Mountain Front of northwestern Montana (Schallenberger and Jonkel, annual rep., Border Grizzly Project, Univ. Montana, Missoula, 1980).  The nuts of the European stone pine (<i>P. cembra</i>) are an important food for brown bears (<i>U. arctos</i>) throughout the taiga zone in the Soviet Union (Pavlov and Zhdanov 1972, Ustinov 1972, Yazan 1972).  Both the production of whitebark pine cones (Forcella 1977, Blanchard 1978, Mealey 1980) and the quantity of nuts consumed by bears vary annually (Mealey 1975, Blancard 1978).</p>\n<br/>\n<p>Pine nuts are also an important food for red squirrels in whitebark forests.  In fall, squirrels remove cones from trees and cache them in middens.  Bears as well as other mammalian and avian seed predators compete with squirrels for whitebark nuts (Forcella 1977, Tomback 1977).</p>\n<br/>\n<p>Confusion about the ripening process of whitebark pine cones has resulted in errors in the literature on the availability of pine nuts as a bear food.  Whitebark cones are indehiscent and do not disintegrate (Tomback 1981).  Vertebrate foraging probably leaves few, if any, seed-bearing cones on trees by late fall; the cones remaining abscise sometime thereafter (Tomback 1981).  Because cones do not abscise or release their seed in fall, bears may obtain pine nuts in 2 ways.  Black bears may climb whitebark pine trees and break off cone-bearing brnahces to feed on cones (Tisch 1961, Mealey 1975, Forcella 1977); or both black bears and grizzly bears may raid squirrel caches to feed on pine nuts (Tisch 1961, Craighead and Craighead 1972, Blanchard 1978).  The purpose of this study was to determine (1) the major source of pine nuts for bears, (2) why cone scales do not appear in bear scat containing pine nuts, and (3) what factors influence bear use of pine nuts.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bears: Their Biology and Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"International Conference on Bear Research and Management","publisherLocation":"New York, NY","doi":"10.2307/3872534","usgsCitation":"Kendall, K.C., 1983, Use of pine nuts by grizzly and black bears in the Yellowstone area: Bears: Their Biology and Management, v. 5, p. 166-173, https://doi.org/10.2307/3872534.","productDescription":"8 p.","startPage":"166","endPage":"173","numberOfPages":"8","costCenters":[],"links":[{"id":292188,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":292187,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2307/3872534"}],"country":"United States","otherGeospatial":"Yellowstone National Park","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -111.156,44.1324 ], [ -111.156,45.109 ], [ -109.8242,45.109 ], [ -109.8242,44.1324 ], [ -111.156,44.1324 ] ] ] } } ] }","volume":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53edcd56e4b0f61b386d24be","contributors":{"authors":[{"text":"Kendall, Katherine C. 0000-0002-4831-2287 kkendall@usgs.gov","orcid":"https://orcid.org/0000-0002-4831-2287","contributorId":3081,"corporation":false,"usgs":true,"family":"Kendall","given":"Katherine","email":"kkendall@usgs.gov","middleInitial":"C.","affiliations":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"preferred":true,"id":498178,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
