Anaerobic oxalate degradation: Widespread natural occurrence in aquatic sediments
Richard L. Smith, Ronald S. Oremland
1983, Applied and Environmental Microbiology (46) 106-113
Significant concentrations of oxalate (dissolved plus particulate) were present in sediments taken from a diversity of aquatic environments, ranging from 0.1 to 0.7 mmol/liter of sediment. These included pelagic and littoral sediments from two freshwater lakes (Searsville Lake, Calif., and Lake Tahoe, Calif.), a hypersaline, meromictic,...

Investigation of the intensity patterns of earthquakes of E Asia indicates a strong regional pattern of attenuation parameter k and systematic correlation of this pattern with topography, P residuals, and level of seismicity as in the USA.-Author...
SELECTED CHEMICAL ANALYSES AND GEOTHERMOMETRY OF HOT SPRING WATERS FROM THE CALABOZOS CALDERA, CENTRAL CHILE.
J. M. Thompson, A.L. Grunder, Wes Hildreth
1983, Conference Paper, Transactions - Geothermal Resources Council
Hot springs discharging from the active hydrothermal system associated with the Calabozos caldera, Chile, have measured orifice temperatures as high as 98. 5 degree C and calculated geothermometer temperatures as high as 250 degree C. Three types of spring waters can be identified from the chemical analyses: a Na-Cl type,...

Computer generation and placement of map type has been refined into a production mode at Mid-Continent Mapping Center (MCMC) for USGS 1:24,000- and 1:25,000-scale Provisional maps. The map collar program is written in FORTRAN using batch processing that allows the program to work in the background....
A note on the chemistry of seawater in the range 350°-500°C
James L. Bischoff, Robert J. Rosenbauer
1983, Geochimica et Cosmochimica Acta (47) 139-144
The chemistry of seawater at conditions of 350° to 500°C, 220 to 1000 bars (22 to 100 MPa) is controlled by reactions involving magnesium hydroxide sulfate (MHSH) and anhydrite. During progressive heating from 350° to 500°C at 1000 bars (100 MPa), MHSH with a <img class="imgLazyJSB inlineImage" title="" src="http://ars.els-cdn.com/content/image/1-s2.0-0016703783900984-si1.gif"...
Paleotemperature oscillations in the Middle and Late Miocene of the northeastern Pacific.

1983, Micropaleontology (29) 150-181
The paleoclimatic and paleoceanographic history has been studied in a N-S transect encompassing DSDP Site 173, the Newport Beach surface section, and DSDP Site 470, based on quantitative diatom and planktic foraminiferal analyses. Fourteen cold and 12 warm events that show close agreement with other microfossil studies as well as...
Ferruginous hawk populations and habitat use in North Dakota
David S. Gilmer, Robert E. Stewart
1983, Journal of Wildlife Management (47) 146-157
Ferruginous hawks (Buteo regalis) were studied in central North Dakota on a 1,259-km2 intensive study block and on a surrounding study area (16,519 km2) from 1977 to 1979. A total of 629 occupied nests was examined. Highest nest densities (0.08 nest/km2) were in the Missouri Coteau in 1979. Few nests...

An important aspect of the petrographic description of coal is the characterization of coal quality, including chemical attributes. For geologic investigations, data on the concentrations, distribution, and modes of occurrence of minor and trace elements provide a basis for reconstructing the probable geochemical environment of the swamp material that was...

Mechanism and ecological significance of sperm storage in the Northern Fulmar with reference to its occurrence in other birds
Scott A. Hatch
1983, The Auk (100) 593-600
Sperm-storage glands were found in the uterovaginal (UV) region of the oviduct in Northern Fulmars (Fulmarus glacialis), Horned Puffins (Fratercula corniculata), and Leach's Storm-Petrels (Oceanodroma leucorhoa) collected before or shortly after egg laying. Previously described only in domestic Galliformes, UV sperm-storage glands may prove to be a common feature of...

Pacific Coast Caspian Terns: Dynamics of an expanding population
Robert E. Gill Jr., L. Richard Mewaldt
1983, The Auk (100) 369-381
Nesting distribution, age-related seasonal movements, survivorship, and mechanisms of population expansion in Pacific Coast Caspian Terns (Sterna caspia) were examined primarily through analysis of 412 recoveries of birds banded as juveniles between 1935 and 1980. Since the beginning of this century, the population has shifted from nesting in numerous small...
Hydrogeologic and water-quality characteristics of the Prairie du Chien-Jordan aquifer, Southeast Minnesota
J. F. Ruhl, R. J. Wolf, D. G. Adolphson
1983, Water-Resources Investigations Report 83-4045
Quality of water in the Prairie du Chien-Jordan aquifer is generally good, except for some localized contamination, Coal-tar derivatives that contaminate the aquifer in St. Louis Park, a western suburb in the Twin Cities Metropolitan Area, pose the most serious threat to water quality. High hardness and iron concentration limit...
Selective concentration of aromatic bases from water with a resin adsorbent
H. A. Stuber, Jerry A. Leenheer
1983, Analytical Chemistry (55) 111-115
Aromatic bases are concentrated from water on columns of a resin adsorbent and recovered by aqueous-acid elution. The degree of concentration attainable depends on the ratio of the capacity factor (k) of the neutral form of the amine to that of the ionized form. Capacity factors of ionic forms of...

On June 4, 1982, two full dredge hauls of fresh lava were recovered from the upper flanks of Kavachi submarine volcano, Solomon Islands, in the western Pacific Ocean, from the water depths of 1,200 and 2,700 feet. the shallower dredge site was within 0.5 mile of the active submarine vent...
Nature and mechanics of the mount St Helens rockslide — avalanche of 18 May 1980
Barry Voight, R. J. Janda, H. Glicken
1983, Geotechnique (20) A176
The bulging sector of the north slope of Mount St. Helens collapsed on 18 May 1980, triggered by an earthquake, thereby creating a tremendous mass movement. This movement in turn initiated volcanic eruptions resulting in the formation of an avalanche of debris. Limit equilibrium analysis of the slope suggests that...
