Chemical reactions that occur in landfills are analogous to those reactions that occur in marine sediments. 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.

Uranium-series disequilibrium studies carried out on samples from the Yeelirrie uranium deposit, Western Australia, indicate that uranium and radium have been migrating within the deposit during recent times, and are actually being removed from the deposit. Samples collected for 230Th/234U age dating were found to be substantially out of equilibrium, with 230Th/234U activity ratios ranging from 0.750 to 1.345. This can be explained by a dynamic hydrologic system in which there has been, and continues to be, uranium migration caused by leaching in this arid, oxidizing environment, and a fluctuating water table.
Recent, extensive 226Ra migration (226Ra/230Th activity ratios range from 0.53 to 1.30), and a very low emanation factor (E) of 222Rn limit the quantitative application of radon exploration techniques in this environment.

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":70012559,"text":"70012559 - 1979 - Martian channels and the search for extraterrestrial life","interactions":[],"lastModifiedDate":"2012-03-12T17:19:03","indexId":"70012559","displayToPublicDate":"1979-01-01T00:00:00","publicationYear":"1979","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2392,"text":"Journal of Molecular Evolution","active":true,"publicationSubtype":{"id":10}},"title":"Martian channels and the search for extraterrestrial life","docAbstract":"The origin of the channels on Mars has been a subject of intense interest since they were first recognized on early Mariner 9 images (Driscoll, 1972; Masursky, 1973).

It is shown that improvement is possible when three component observatory data are available from a single station in the general, but not necessarily immediate, vicinity of an array of total field stations used in a tectonomagnetic study. The local effects of a magnetic disturbance field depend upon its orientation, so that local field differences are more effectively generated by certain orientations of the disturbance field. The orientation of the disturbance field which correlates best with a local difference field is determined by a least-squares method, so that the correlated vector signal can be routinely subtracted from the difference field record. Application of the technique to daily averages of records from three synchronised proton magnetometers on Kilauea volcano reveals a 1.5-nT change in the local field at the time of a flank eruption in May, 1973. This effect was obscured by noise in the raw difference field 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)90005-0","issn":"00319201","usgsCitation":"Davis, P., Stacey, F., Zablocki, C., and Olson, J., 1979, Improved signal discrimination in tectonomagnetism: Discovery of a volcanomagnetic effect at Kilauea, Hawaii: Physics of the Earth and Planetary Interiors, v. 19, no. 4, p. 331-336, https://doi.org/10.1016/0031-9201(79)90005-0.","startPage":"331","endPage":"336","numberOfPages":"6","costCenters":[],"links":[{"id":222138,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":267348,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0031-9201(79)90005-0"}],"volume":"19","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3964e4b0c8380cd618e5","contributors":{"authors":[{"text":"Davis, P.M.","contributorId":15229,"corporation":false,"usgs":true,"family":"Davis","given":"P.M.","email":"","affiliations":[],"preferred":false,"id":363557,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stacey, F.D.","contributorId":59176,"corporation":false,"usgs":true,"family":"Stacey","given":"F.D.","email":"","affiliations":[],"preferred":false,"id":363559,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Zablocki, C.J.","contributorId":52178,"corporation":false,"usgs":true,"family":"Zablocki","given":"C.J.","affiliations":[],"preferred":false,"id":363558,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Olson, J.V.","contributorId":71836,"corporation":false,"usgs":true,"family":"Olson","given":"J.V.","email":"","affiliations":[],"preferred":false,"id":363560,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":70012620,"text":"70012620 - 1979 - Seismic gaps and source zones of recent large earthquakes in coastal Peru","interactions":[],"lastModifiedDate":"2012-03-12T17:19:07","indexId":"70012620","displayToPublicDate":"1979-01-01T00:00:00","publicationYear":"1979","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3209,"text":"Pure and Applied Geophysics PAGEOPH","active":true,"publicationSubtype":{"id":10}},"title":"Seismic gaps and source zones of recent large earthquakes in coastal Peru","docAbstract":"The earthquakes of central coastal Peru occur principally in two distinct zones of shallow earthquake activity that are inland of and parallel to the axis of the Peru Trench. 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.

An acute toxicity curve for dissolved ozone (O3) in soft water at 10 °C, using 10–13-cm rainbow trout (Salmo gairdneri) as the test species was calculated. The 96-h LC50 (95%, confidence interval) was 9.3 (8.1–10.6) μg/L. The lethal threshold level was about 8 μg/L mandating that a conservative margin of safety be used if ozone is employed as a fish disease control agent. Death apparently results from massive destruction of the gill lamellar epithelium together with a severe hydromineral imbalance. In partial chronic (3-mo) testing, 2 μg/L caused no significant biological damage while 5 μg/L caused some gill pathological changes and reduced feeding behavior. Accordingly, 2 μg/L is suggested as a provisional maximum safe exposure level, pending completion of life cycle studies. Thus, if ozone-treated water is discharged into the environment, dissolved O3 should be reduced to at least the 2 μg/L level to minimize adverse impacts on salmonids in receiving waters.

By the method of electron reflection, we have identified seven well-defined magnetized regions in the equatorial belt of the lunar far side sampled by the Apollo 16 Particles and Fields subsatellite. Most of these surface magnetic fields lie within one basin radius from the rim of a ringed impact basin, where thick deposits of basin ejecta are observed or inferred. The strongest of the seven magnetic features is linear, at least 250 km long, and radial to the Freundlich-Sharonov basin. The apparent correlation with basin ejecta suggests some form of impact origin for the observed permanently magnetized regions.

Recent studies of DSDP samples from layer 2A of oceanic basement have found complex magnetic stratigraphies that seem incompatible with the frequent existence of linear short-wavelength anomalies caused by palaeomagnetic field behavior. Statistical models are developed for the lateral variation of the average magnetization of layer 2A: a Poisson series for reversals of the earth's field and a stairstep random series for discrete magnetic units. It is shown with the power-density spectra of these statistical models that lateral inhomogeneities must average out over distances of less than a few hundred meters. Specifically, individual magnetic units of the type seen at DSDP Site 332 cannot extend uniformly for distances greater than a few hundred meters.

Many of the measurements of phyiscal properties being made in earthquake prediction studies are based on the premise that these properties are influenced by stresses and strains, especially so near the failure point. Electrical properties of rocks are controlled by the fluid in the pores and cracks in the rocks. Because these regions are most influenced by stresses, one should expect electrical measurements to be sensitive measures of changing stresses and strains. Nevertheless, the strain changes we are dealing with are very small, and, consequently, we need very sensitive instruments to detect them.

Beginning in the early 1960's, reports from the Soviet Union described travel-time anomalies of 5 to 20 percent preceding large earthquakes. In the early 970's, similar observations began to be reported outside the U.S.S.R. The most convincing were anomalously low values of the velocity ration, Vp/Vs, before four earthquakes of magnitudes 2.5 to 3.3 at Blue Mountain Lake, N.Y.; the anomalies were based on large amounts of high-quality data. In Japan, significant decreases were observed in the travel-time ratio, ts/tp, before two thrust-type earthquakes of magnitudes 6. and 5.3. Finally, there is the much discussed report of an anomaly before the magnitude 6.4 San Fernando, Calif., earthquake of 1971 and the implication that the change was caused principally by a decrease in the velocity of the primary (P) wave.

Historic records of earthquakes are too short to allow a true assessment of their recurrence intervals. Methods are needed, therefore, that will enable the seismicity of an area to be evaluated beyond the limit of historic records.

\n

One place where a record of ancient seismic activity might be preserved is in lake sediments. Strong earthquakes often cause a phenomenon in water-saturated sediments known as liquefaction. The seismic shaking tends to reorient the sediment grains into a more compact arrangement. This usually means that the sediment liquefies and is redeposited in a smaller volume; there is an accompanying explusion of water and, in cases of severe shaking, sediment-laden water.

\n

During a strong earthquake, deformation due to liquefaction may occur in the upper layers of lake sediment. If this deformation is preserved without further deformation as new layers of sediment are deposited in the lake and if one could later find and identify these layers, one would then have a record of prehistoric earthquakes in the lake beds.

Since the beginning of modern seismology, seismologists have contemplated predicting earthquakes. The usefulness of earthquake predictions to the reduction of human and economic losses and the value of long-range earthquake prediction to planning is obvious. Not as clear are the long-range economic and social impacts of earthquake prediction to a speicifc area. The general consensus of opinion among scientists and government officials, however, is that the quest of earthquake prediction is a worthwhile goal and should be prusued with a sense of urgency.
