Estimates of the parameters and quantiles of the Gumbel distribution by the methods of probability weighted moments, (conventional) moments, and maximum likelihood were compared. Results were derived from Monte Carlo experiments by using both independent and serially correlated Gumbel numbers. The method of probability weighted moments was seen to compare favorably with the other two techniques.
Special photogrammetric techniques have been developed to portray Mars topography, using Mariner and Viking imaging and nonimaging topographic information and earth-based radar data. Topography is represented by the compilation of maps at three scales: global, intermediate, and very large scale. The global map is a synthesis of topographic information obtained from Mariner 9 and earth-based radar, compiled at a scale of 1:25,000,000 with a contour interval of 1 km; it gives a broad quantitative view of the planet. At intermediate scales, Viking Orbiter photographs of various resolutions are used to compile detailed contour maps of a broad spectrum of prominent geologic features; a contour interval as small as 20 m has been obtained from very high resolution orbital photography. Imagery from the Viking lander facsimile cameras permits construction of detailed, very large scale (1:10) topographic maps of the terrain surrounding the two landers; these maps have a contour interval of 1 cm. This paper presents several new detailed topographic maps of Mars.

The largest single anomaly found within the region of coverage on the near-side map correlates exactly with a conspicuous, light-colored marking in western Oceanus Procellarum called Reiner Gamma. This feature is interpreted as an unusual deposit of ejecta from secondary craters of the large nearby primary impact crater Cavalerius. An age for Cavalerius (and, by implication, for Reiner Gamma) of 3.2 ?? 0.2 ?? 109 y is estimated. The main (30 ?? 60 km) Reiner Gamma deposit is nearly uniformly magnetized in a single direction, with a minimum mean magnetization intensity of ???7 ?? 10-2 G cm3/g (assuming a density of 3 g/cm3), or about 700 times the stable magnetization component of the most magnetic returned samples. Additional medium-amplitude anomalies exist over the Fra Mauro Formation (Imbrium basin ejecta emplaced ???3.9 ?? 109 y ago) where it has not been flooded by mare basalt flows, but are nearly absent over the maria and over the craters Copernicus, Kepler, and Reiner and their encircling ejecta mantles. The mean altitude of the far-side anomaly gap is much higher than that of the near-side map and the surface geology is more complex, so individual anomaly sources have not yet been identified. However, it is clear that a concentration of especially strong sources exists in the vicinity of the craters Van de Graaff and Aitken. Numerical modeling of the associated fields reveals that the source locations do not correspond with the larger primary impact craters of the region and, by analogy with Reiner Gamma, may be less conspicuous secondary crater ejecta deposits. The reason for a special concentration of strong sources in the Van de Graaff-Aitken region is unknown, but may be indirectly related to the existence of strongly modified crustal terrain which also occurs in the same region. The inferred directions of magnetization for the several sources of the largest anomalies are highly inclined with respect to one another, but are generally depleted in the north-south direction. The north-south depletion of magnetization intensity appears to continue across the far-side within the region of coverage. The mechanism of magnetization and the origin of the magnetizing field remain unresolved, but the uniformity with which the Reiner Gamma deposit is apparently magnetized, and the north-south depletion of magnetization intensity across a substantial portion of the far side, seem to require the existence of an ambient field, perhaps of global or larger extent. The very different inferred directions of magnetization possessed by nearly adjacent sources of the Van de Graaff-Aitken anomalies, and the depletion in their north-south component of magnetization, do not favor an internally generated dipolar field oriented parallel to the present spin axis. A variably oriented interplanetary magnetizing field that was intrinsically strong or locally amplified by unknown surface processes is least inconsistent with the data. ?? 1979.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Physics of the Earth and Planetary Interiors","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/0031-9201(79)90052-9","issn":"00319201","usgsCitation":"Hood, L.L., Coleman, P., Russell, C., and Wilhelms, D., 1979, Lunar magnetic anomalies detected by the Apollo substatellite magnetometers: Physics of the Earth and Planetary Interiors, v. 20, no. 2-4, p. 291-311, https://doi.org/10.1016/0031-9201(79)90052-9.","startPage":"291","endPage":"311","numberOfPages":"21","costCenters":[],"links":[{"id":222666,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":267349,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0031-9201(79)90052-9"}],"volume":"20","issue":"2-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4a91e4b0c8380cd68e8f","contributors":{"authors":[{"text":"Hood, L.

The area, defined as that in which the nodules contain more than 1.8 percent nickel plus copper, is about 2o5 million km2. The available evidence suggests that about half of it contains nodules in concentration (reported in wet weight units) greater than 5 kg/m2 and averaging 11.9 kg/m2. If we assume that 20 percent of the nodules in this area of 1.25 million km2 are recoverable, its potential recoverable resources are about 2.1 billion dry metric tons of nodules averaging about 25 percent Mn, 1.3 percent Ni, 1.0 percent Cu, 0.22 percent Co, and 0.05 percent Mo—enough to support about 27 mining operations each producing an average of 75 million metric tons of nodules over their lifetimes. Estimates based on other plausible assumptions would be higher or lower, but of the same order of magnitude. Thus it seems probable that the magnitude of the potentially recoverable nodule resources of the Clarion-Clipperton prime area—the most promising now known—is at most in the range of several tens of the average-size operations postulated.

The interface-thrust (IT) zone includes the great thrust-fault earthquakes of 17 October 1966 and 3 October 1974. The coastal-plate interior (CPI) zone includes the great earthquake of 31 May 1970, and is located about 50 km inland of and 30 km deeper than the interface thrust zone. The occurrence of a large earthquake in one zone may not relieve elastic strain in the adjoining zone, thus complicating the application of the seismic gap concept to central coastal Peru. However, recognition of two seismic zones may facilitate detection of seismicity precursory to a large earthquake in a given zone; removal of probable CPI-zone earthquakes from plots of seismicity prior to the 1974 main shock dramatically emphasizes the high seismic activity near the rupture zone of that earthquake in the five years preceding the main shock. Other conclusions on the seismicity of coastal Peru that affect the application of the seismic gap concept to this region are: (1) Aftershocks of the great earthquakes of 1966, 1970, and 1974 occurred in spatially separated clusters. Some clusters may represent distinct small source regions triggered by the main shock rather than delimiting the total extent of main-shock rupture. The uncertainty in the interpretation of aftershock clusters results in corresponding uncertainties in estimates of stress drop and estimates of the dimensions of the seismic gap that has been filled by a major earthquake. (2) Aftershocks of the great thrust-fault earthquakes of 1966 and 1974 generally did not extend seaward as far as the Peru Trench. (3) None of the three great earthquakes produced significant teleseismic activity in the following month in the source regions of the other two earthquakes. The earthquake hypocenters that form the basis of this study were relocated using station adjustments computed by the method of joint hypocenter determination. ?? 1979 Birkha??user Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Pure and Applied Geophysics PAGEOPH","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Birkha??user-Verlag","doi":"10.1007/BF00876212","issn":"00334553","usgsCitation":"Dewey, J.W., and Spence, W., 1979, Seismic gaps and source zones of recent large earthquakes in coastal Peru: Pure and Applied Geophysics PAGEOPH, v. 117, no. 6, p. 1148-1171, https://doi.org/10.1007/BF00876212.","startPage":"1148","endPage":"1171","numberOfPages":"24","costCenters":[],"links":[{"id":222489,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":205248,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00876212"}],"volume":"117","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8b15e4b08c986b317597","contributors":{"authors":[{"text":"Dewey, J.

Measured vertical changes as great as 3-5 cm per year indicate that two types of tectonic movement are occurring: (1) a downward regional tilt of the valley surface from the Mexican border northward toward Salton Sea, and (2) a deepening of the structural trough presently occupied by Salton Sea. A comparison of 1972ndash;1977 change contours with 1927 topographic contours shows gross parallelism, suggesting that the recent deformation is a continuation of the tectonism that formed the Salton trough. Ground movement since 1972 has tended to steepen slightly the gradients of streams, canals, and drains on the valley floor and to increase the capacity of Salton Sea. A usable record of eight years of background measurements of tectonic change are available prior to the impact of geothermal production in Imperial Valley. ?? 1979.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geothermics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/0375-6505(79)90050-6","issn":"03756505","usgsCitation":"Lofgren, B.E., 1979, Measured crustal deformation in Imperial Valley, California: Geothermics, v. 8, no. 3-4, p. 267-272, https://doi.org/10.1016/0375-6505(79)90050-6.","startPage":"267","endPage":"272","numberOfPages":"6","costCenters":[],"links":[{"id":222484,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":268147,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0375-6505(79)90050-6"}],"volume":"8","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a52c1e4b0c8380cd6c661","contributors":{"authors":[{"text":"Lofgren, B.

Progress waned again until the middle 20th century when an International Hydrological Decade was conceived, eventually receiving wide multinational support from governmental agencies and nongovernmental institutions. Organized by UNESCO, the Decade program was launched January 1, 1965. Participation included 107 nations, six United Nations agencies, and more than a dozen international scientific organizations. The initial program emphasized scientific research, and international cooperation; the second half of the Decade, emphasized technical assistance and technology transfer, largerly through education, training and demonstration. The success of the Decade led to the establishment of the International Hydrological Program, again under the aegis of UNESCO, to continue the work of the Decade indefinitely. The five major program activities, now involving about 90 countries and several international organizations, include: the scientific program, the promotion of education and training, the enhancement of information exchange, support of technical assistance, and the enlargement of regional cooperation. A significant amount of activity related to hydrological data networks and forecasting is carried on in an Operational Hydrology Programme by the WMO, chiefly through its Commission for Hydrology. Other international governmental organizations with a strong interest in water include the UN, the UN Development Programme, the FAO, the WHO, the International Atomic Energy Agency, the UN Environment Programme, the International Standardization Organization, and developmental institutions such as the World Bank. The specialized interests of researchers outside of the governmental structure, are met through association in various scientific and technical organizations which are world wide in scope and membership. Notwithstanding a sometimes bewildering variety of organizations, there certainly exists, for any nation, group, or individual, a demonstrated mechanism for almost any conceivable form of international cooperation in hydrology and water resources. ?? 1979 Akademische Verlagsgesellschaft.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"GeoJournal","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Kluwer Academic Publishers","doi":"10.1007/BF00455987","issn":"03432521","usgsCitation":"Jones, J., Beall, R., and Giusti, E., 1979, International cooperation in water resources: GeoJournal, v. 3, no. 5, p. 481-487, https://doi.org/10.1007/BF00455987.","startPage":"481","endPage":"487","numberOfPages":"7","costCenters":[],"links":[{"id":222025,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":205185,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00455987"}],"volume":"3","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3d39e4b0c8380cd633d1","contributors":{"authors":[{"text":"Jones, J.R.","contributorId":15967,"corporation":false,"usgs":true,"family":"Jones","given":"J.R.","email":"","affiliations":[],"preferred":false,"id":363987,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Beall, R.M.","contributorId":88392,"corporation":false,"usgs":true,"family":"Beall","given":"R.M.","email":"","affiliations":[],"preferred":false,"id":363989,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Giusti, E.V.","contributorId":51342,"corporation":false,"usgs":true,"family":"Giusti","given":"E.V.","affiliations":[],"preferred":false,"id":363988,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":70012528,"text":"70012528 - 1979 - Geochemical surveys in the United States in relation to health.","interactions":[],"lastModifiedDate":"2013-01-21T18:18:16","indexId":"70012528","displayToPublicDate":"1979-01-01T00:00:00","publicationYear":"1979","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3048,"text":"Philosophical Transactions of the Royal Society B: Biological Sciences","active":true,"publicationSubtype":{"id":10}},"title":"Geochemical surveys in the United States in relation to health.","docAbstract":"Geochemical surveys in relation to health may be classified as having one, two or three dimensions.

The primary objective of two-dimensional surveys is to map the distributions of element concentrations, commonly according to stratified random sampling designs based on either conceptual landscape units or artificial sampling strata, but systematic sampling intervals have also been used. Political units have defined sample areas that coincide with the units used to accumulate epidemiological data. Element concentrations affected by point sources have also been mapped. Background values, location of natural or technological anomalies and the geographic scale of variation for several elements often are determined.

Sulfur contents of basalt glass from several places on the sand-rubble flow and nearby areas are low (< 240 ppm), indicating that the clastic basaltic material was all erupted on land. The Papa'u sandrubble flow was emplaced during a single flow event fed from a large near-shore bank of clastic basaltic material which in turn was formed as lava flows from the summit area of Kilauea volcano disintegrated when they entered the sea. The current eruptive output of the volcano suggests that the material in the submarine sand-rubble flow represents about 6000 years of accumulation, and that the flow event occurred several thousand years ago. ?? 1979.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Volcanology and Geothermal Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"03770273","usgsCitation":"Fornari, D., Moore, J., and Calk, L., 1979, A large submarine sand-rubble flow on kilauea volcano, hawaii: Journal of Volcanology and Geothermal Research, v. 5, no. 3-4, p. 239-256.","startPage":"239","endPage":"256","numberOfPages":"18","costCenters":[],"links":[{"id":222594,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"5","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e432e4b0c8380cd464bb","contributors":{"authors":[{"text":"Fornari, D.J.","contributorId":49520,"corporation":false,"usgs":true,"family":"Fornari","given":"D.J.","email":"","affiliations":[],"preferred":false,"id":363620,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Moore, J.G.","contributorId":67496,"corporation":false,"usgs":true,"family":"Moore","given":"J.G.","email":"","affiliations":[],"preferred":false,"id":363621,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Calk, L.","contributorId":106264,"corporation":false,"usgs":true,"family":"Calk","given":"L.","affiliations":[],"preferred":false,"id":363622,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":70012510,"text":"70012510 - 1979 - Preliminary geological mapping of Io","interactions":[],"lastModifiedDate":"2012-03-12T17:19:06","indexId":"70012510","displayToPublicDate":"1979-01-01T00:00:00","publicationYear":"1979","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2840,"text":"Nature","active":true,"publicationSubtype":{"id":10}},"title":"Preliminary geological mapping of Io","docAbstract":"Terrain units and their global distribution on Io are summarised.

A triangular or square drilling pattern should be used when the orientations of the targets are unknown. The way in which the optimum hole spacing varies as a function of (1) the cost of drilling, (2) the value of the targets, (3) the shape of the targets, (4) the target occurrence probabilities was determined for several examples.

Pressure decreases due to production in the southeastern part of the field have produced both drawdown of lower chloride fluids from an overlying aquifer and boiling in the aquifer with excess steam reaching the wells. These reservoir changes are indicated by changes in fluid chloride concentrations, Na/K ratios and measured enthalpies and by comparisons of aquifer fluid temperatures and chloride concentrations calculated from enthalpy and chemical measurements. Fluid temperatures have not been greatly affected by this drawdown because heat contained in the rock was transferred to the fluid. When this heat is exhausted, fluid temperatures may drop rapidly. ?? 1979.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geothermics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/0375-6505(79)90049-X","issn":"03756505","usgsCitation":"Truesdell, A., Manon, M., Jimenez, S., Sanchez, A., and Fausto, L., 1979, Geochemical evidence of drawdown in the Cerro Prieto geothermal field: Geothermics, v. 8, no. 3-4, p. 257-265, https://doi.org/10.1016/0375-6505(79)90049-X.","startPage":"257","endPage":"265","numberOfPages":"9","costCenters":[],"links":[{"id":268148,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0375-6505(79)90049-X"},{"id":222540,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"8","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a1634e4b0c8380cd550b0","contributors":{"authors":[{"text":"Truesdell, A.H.","contributorId":52566,"corporation":false,"usgs":false,"family":"Truesdell","given":"A.H.","email":"","affiliations":[{"id":6672,"text":"former: USGS Southwest Biological Science Center, Colorado Plateau Research Station, Flagstaff, AZ.

Lateral zonation of C, N, S, O, H, Fe and Mn species in landfills is similar to the vertical zonation of these species in marine sediments and results from the following reaction sequence: (1) oxidation of C, N and S species in the presence of dissolved free oxygen to HCO3-, NO3-and SO42; (2) after consumption of molecular oxygen, then NO3-is reduced, and Fe and Mn are solubilized; (3) SO42-is reduced to sulfide; and (4) organic compounds become the source of oxygen, and CH4 and NH4+are formed as fermentation products. In a landfill in Delaware the oxidation potential increases down-gradient and the redox zones in the reducing plume are characterized by: CH4, NH4+,Fe2+. Mn2+, HCO3-and NO3-. Lack of SO42-at that landfill eliminates the sulfide zone. Although it has not been observed at landfills, mineral alteration should result in precipitation of pyrite and/or siderite downgradient. Controls on the pH of leachate are the relative rates of production of HCO3-, NH4+and CH4. Production of methane by fermentation at landfills results in 13C isotope fractionation and the accumulation of isotopically heavy σ CO2 (+10 to +180/00 PDB). Isotope measurements may be useful to determine the extent of CO2 reduction in landfills and extent of dilution downgradient. The boundaries of reaction zones in stressed aquifers are determined by head distribution and flow velocity. Thus, if the groundwater flow is rapid relative to reaction rates, redox zones will develop downgradient. Where groundwater flow velocities are low the zones will overlap to the extent that they may be indeterminate.
