Pair-counts indicated a decline from 70 pairs of waterfowl in 1965 to 2 pairs in 1968. Nest success of upland nesting blue-winged teal (Anas discors) averaged 33% and mallards (Anas platyrhyncos) averaged 23%. Blue-winged teal selected nest sites closer to water than did mallards (314 feet versus 424 feet). Teal nested in ungrazed bluegrass (Poa pratensis) in preference to alfalfa (Medicago sativa) hayland. Bromegrass (Bromus inermis) was readily used by teal and mallards when it became available for nesting. Nest success of species nesting overwater was considerably higher: Redheads (Aythya americana) were 55% successful and 93% of 75 coot (Fulica americana) nests hatched. A study of dummy-nests showed nest success significantly higher on ungrazed than on grazed bluegrass. Grazing did not significantly lower total mouse populations but did change species composition because deer mice (Peromyscus maniculatus) increased as other species declined with grazing.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Iowa State Journal of Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Krapu, G., Parsons, D., and Weller, M., 1970, Waterfowl in relation to land use and water levels on the Spring Run Area: Iowa State Journal of Science, v. 44, no. 4, p. 437-452.","productDescription":"16 p.","startPage":"437","endPage":"452","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":133749,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -91.34994506835938,\n 41.24180361544047\n ],\n [\n -91.31132125854492,\n 41.24180361544047\n ],\n [\n -91.31132125854492,\n 41.27109776324752\n ],\n [\n -91.34994506835938,\n 41.27109776324752\n ],\n [\n -91.34994506835938,\n 41.24180361544047\n ]\n ]\n ]\n }\n }\n ]\n}","volume":"44","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49dfe4b07f02db5e3bcd","contributors":{"authors":[{"text":"Krapu, Gary L.","contributorId":56994,"corporation":false,"usgs":true,"family":"Krapu","given":"Gary L.","affiliations":[],"preferred":false,"id":311808,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Parsons, D.R.","contributorId":84322,"corporation":false,"usgs":true,"family":"Parsons","given":"D.R.","email":"","affiliations":[],"preferred":false,"id":311809,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Weller, M.W.","contributorId":54562,"corporation":false,"usgs":true,"family":"Weller","given":"M.W.","email":"","affiliations":[],"preferred":false,"id":311807,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":2000043,"text":"2000043 - 1970 - Trends in fishery management of the Great Lakes","interactions":[],"lastModifiedDate":"2012-02-02T00:15:02","indexId":"2000043","displayToPublicDate":"1970-01-01T00:00:00","publicationYear":"1970","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":3,"text":"Organization Series"},"seriesTitle":{"id":217,"text":"Special Publication","active":false,"publicationSubtype":{"id":3}},"seriesNumber":"7","title":"Trends in fishery management of the Great Lakes","docAbstract":"Some hope is returning for recovery of the fish stocks of the Great Lakes, which have been outstanding examples of abuse although they are the world's largest and most valuable freshwater fishery resource.

Under favorable conditions the chemistry of hot springs may give reliable indications of subsurface temperatures and circulation patterns. These chemical indicators can be classified by the type of process involved:

IndicatorDominant Process
The silica geothermometerSolution-precipitation
Alkali ratiosIon exchange
Cl/(HCO3 + CO3) ratioRock alteration by dissolved

CO2
Relative concentration ofPartitioning owing to subsur-
volatiles in spring waterface boning

All these indicators have certain limitations. The silica geothermometer gives results independent of the local mineral suite and gas partial pressures, but may be affected by dilution. Alkali ratios are strongly affected by the local mineral suite and the formation of complex ions. Carbonate-chloride ratios are strongly affected by subsurface PCO2. The relative concentration of volatiles can be very misleading in high-pressure liquid systems.

In Yellowstone National Park most thermal waters issue from hot, shallow aquifers with pressures in excess of hydrostatic by 2 to 6 bars and with large flows (the flow of hot spring water from the Park is greater than 4000 liters per second). These conditions should be ideal for the use of chemical indicators to estimate aquifer temperatures. In five drill holes aquifer temperatures were within 2°C of that predicted from the silica content of nearby hot springs; the temperature level off at a lower value than predicted in only one hole, and in four other holes drilling was terminated before the predicted aquifer temperature was reached.

The temperature-Na/K ratio relationship does not follow any published experimental or empirical curve for water-feldspar or water-clay reactions. We suspect that ion exchange reactions involving zeolites in the Yellowstone rocks result in higher Na/K ratios at given temperatures than result from feldspar or clay reactions. Comparison of SiO2 and Cl/(HCO3 + CO3) suggest that because of higher subsurface PCO2 in Upper Geyser Basin a given Cl/(HCO3 + CO3) ratio there means a higher temperature than in Lower Geyser Basin. No correlation was found in Yellowstone Park between the subsurface regions of highest temperature and the relative concentration of volatile components such as boron and ammonia.

The Television Experiment objectives are to provide imaging data which will complement previously gathered data and extend our knowledge of Mars. The two types of investigations will be fixed-feature (for mapping) and variable-feature (for surface and atmospheric changes). Two cameras with a factor-of-ten difference in resolution will be used on each spacecraft for medium- and high-resolution imagery. Mapping of 70% of the planet's surface will be provided by medium-resolution imagery. Spot coverage of about 5% of the surface will be possible with the high-resolution imagery.

The experiment's 5 Principal Investigators and 21 Co-Investigators are organized into a team. Scientific disciplines and technical task groups have been formed to provide the formulation of experiment requirements for mission planning and instrument development. It is expected that the team concept will continue through the operational and reporting phases of the Mariner Mars 1971 Project.

Several hundred quakes were in the magnitude range 4.0 to 5.4 mb, but few such events were recorded after 23 June. Unusual lightning accompanied the major cloud, and, during the evening of 11 June, distant observers reported red glow and flashes from the area. Fine ash fell that night and much of the next day to distances at least 350 km from the volcano.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"AAAS","publisherLocation":"Washington, D.C.","doi":"10.1126/science.169.3944.429","issn":"00368075","usgsCitation":"Simkin, T., and Howard, K.A., 1970, Caldera collapse in the Galápagos Islands, 1968: Science, v. 169, no. 3944, p. 429-437, https://doi.org/10.1126/science.169.3944.429.","productDescription":"9 p.","startPage":"429","endPage":"437","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":219506,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":263892,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1126/science.169.3944.429"}],"country":"Ecuador","otherGeospatial":"Gal�pagos Islands;Isla Fernandina","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -90.805097,-0.471724 ], [ -90.805097,-0.451724 ], [ -90.78509,-0.451724 ], [ -90.78509,-0.471724 ], [ -90.805097,-0.471724 ] ] ] } } ] }","volume":"169","issue":"3944","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f308e4b0c8380cd4b573","contributors":{"authors":[{"text":"Simkin, T.","contributorId":45833,"corporation":false,"usgs":true,"family":"Simkin","given":"T.","email":"","affiliations":[],"preferred":false,"id":357862,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Howard, K.

Both an accelerator and a 252Cf neutron source have been used to induce characteristic gamma radiation from extended soil samples. To demonstrate the method, measurements of the neutron-induced radiative capture and activation gamma rays have been made with both Ge(Li) and NaI(Tl) detectors, Because of the possible application to space flight geochemical analysis, it is believed that NaI(Tl) detectors must be used. Analytical procedures have been developed to obtain both qualitative and semiquantitative results from an interpretation of the measured NaI(Tl) pulse-height spectrum. Experiment results and the analytic procedure are presented.

A rapid and simple method for the radiochemical separation of gold after neutron activation. The technique is based on treatment with a dilute indium-gold amalgam, both chemical reduction and isotopic exchange being involved. The counting efficiency for 198Au in small volumes of the amalgam is good. Few interferences occur and the method is applicable to clays, rocks, salts and metals. The possibility of determining silver, platinum and palladium by a similar method is mentioned.

DELAY-DOPPLER radar maps of the Moon obtained with the 430 MHz (70 cm wavelength) radar of the Arecibo Ionospheric Observatory in Puerto Rico (Thompson, unpublished) are at present being studied to correlate geological information with the radar reflexion characteristics of the lunar surface. Preliminary evaluation of the radar data for the Sinus Iridum quadrangle (32°–48° N; 14°–38° W) has revealed that the lowest values of radar reflectivity are closely correlated with the mare materials of lowest albedo mapped by Schaber1 as of most recent volcanic origin. These radar data were obtained with a surface resolution of 50 to 100 km2 on January 24 and April 17, 1967. A detailed account of the delay-doppler radar mapping technique can be found in unpublished reports by Thompson.

A summary of potassium-argon dates shows that a high level of igneous activity in the Great Basin and adjacent regions during middle Tertiary time (40 to 20 my ago) was followed by a period of relative quiescence in middle Miocene time that lasted for several million years (from 20 to 17 my ago). Volcanism resumed 16 my ago mainly at the margins of the region and has continued to the present.

    Strontium isotopic variations (87Sr/86Sr of 0.7029 to 0.7052) in Quaternary basalts of southeastern California, USA, are not readily explained by assimilation of crustal material similar to that contained as xenoliths in the basalt. Isotopic differences between chrome diopside (0.7016) and olivine (0.7087) from a lherzolite xenolith suggest that the isotopic variations in the basalts may be inherited from the source regions or modified by the upper parts of the mantle that were traversed by the lavas.

    Isotopic analyses of strontium in primary fossil carbonate reveal significant variations in Sr87Sr86\">Sr87Sr86 of sea water during the Phanerozoic. The strontium isotopic composition may have been uniform from the Ordovician through the Mississippian, with an average Sr87Sr86\">Sr87Sr86 of 0.7078. A subsequent decrease in this value into the Mesozoic is interrupted by two provisionally documented positive pulses in Sr87Sr86\">Sr87Sr86—one in the Early Pennsylvanian and one in the Early Triassic. The lowest observed value (0.7068) occurred in Late Jurassic time, and this was followed by a gradual increase to 0.7075 in the Late Cretaceous and a more rapid increase through the Tertiary to 0.7090 for modern sea water. These variations are thought to be the result of a complex interplay of periods of intense volcanism and epeirogenic movements of the continents on a worldwide scale.

    Rocks and minerals are fused with sodium peroxide in the presence of carrierfree 95Nb. The fusion cake is leached with water and the precipitate dissolved in hydrofluoric-sulfuric acid mixture. Niobium is extracted into methyl isobutyl ketone and further purified by ion exchange. The amount of niobium is determined spectrophotometrically with 4-(2-pyridylazo)-resorcinol, and the chemical yield of the separations determined by counting 95Nb. This procedure is faster and less sensitive to interferences than previously proposed methods for determining niobium in rocks. The high purity of the separated niobium makes the method applicable to nearly all matrices.

    Perhaps the most lamentable mistake that one can make is to be right too soon. This was the story of the Brandywine Plan, an attempt to organize local people for the permanent protection of the environmental amenities of their own land.

    The Upper East Branch of Brandywine Creek drains a rolling basin of farms, fields, woodlands, and a sprinkling of residential areas. Because it lies at the far edge of the commuting range to the population centers of Philadelphia and Wilmington, the basin's natural beauty has barely been touched by the blight of suburban sprawl. The waters of its streams are clear; its ample woodlands and fields are filled with wildlife. Driving slowly through the basin's winding roads and across its narrow bridges evokes the feeling of a pastoral painting, of the ideal landscape of rural eastern America.

    For two years, I had the privilege of working closely with a group preparing a land plan for the Brandywine area. The plan was designed to offer the inhabitants of the basin a feasible way to preserve forever the natural qualities of their region from the inevitable wave of urbanization. A report in Science magazine called it the perfect plan that failed.
