Seabirds between Alaska and Hawaii
Patrick J. Gould
1983, The Condor (85) 286-291
Seabirds were observed between Alaska and Hawaii along 158°W longitude from 24 October to 6 November 1976. Their distributions and abundances corresponded remarkably well to oceanographic regions. Indices of seabird density dropped in a series of plateaus from 44 birds/km2 in the Alaska Current System to less than 1 bird/km2...
STABLE ISOTOPE GEOCHEMISTRY OF THERMAL FLUIDS FROM LASSEN VOLCANIC NATIONAL PARK, CALIFORNIA.
Cathy J. Janik, Nancy L. Nehring, Alfred H. Truesdell
1983, Conference Paper, Transactions - Geothermal Resources Council
In the Lassen vapor-dominated geothermal system, surface manifestations of thermal fluids at high elevations (1800-2500 m) include superheated and drowned fumaroles, steam-heated acid-sulfate hot springs, and low-chloride bicarbonate springs. Neutral high-chloride hot water discharges at lower elevations. Deuterium and oxygen-18 data establish genetic connections between these fluids and with local...
Noble gas systematics for coexisting glass and olivine crystals in basalts and dunite xenoliths from Loihi Seamount
I. Kaneoka, N. Takaoka, D.A. Clague
1983, Earth and Planetary Science Letters (66) 427-437
Noble gas isotopes including 3He/4He, 40Ar/36Ar and Xe isotope ratios were determined for coexisting glass and olivine crystals in tholeiitic and alkalic basalts and dunite xenoliths from Loihi Seamount.Glass and coexisting olivine crystals have similar 3He/4He ratios (2.8–3.4) × 10−5, 20 to 24 times the atmospheric ratio (RA), but different 40Ar/36Ar ratios (400–1000). Based...
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...
Nesting biology of laughing gulls in relation to agricultural chemicals in south Texas USA 1978-1981
Donald H. White, C. A. Mitchell, R. M. Prouty
1983, The Wilson Bulletin (95) 540-551
Various aspects of the breeding biology of Laughing Gulls (Larus atricilla) have been studied extensively in Florida (Dinsmore and Schreiber 1974, Schreiber et al. 1979, Schreiber and Schreiber 1980), New Jersey (Bongiorno 1970, Burger and Beer 1976, Burger 1976, Montevecchi 1978), and Massachusetts (Noble and Wurm 1943), but little is...
Hydrothermal alteration of graywacke and basalt by 4 m NaCl
R.J. Rosenbauer, J. L. Bischoff, A. S. Radtke
1983, Economic Geology (78) 1701-1710
Separate experiments at 350 degrees C and 500 bars at a rock/fluid ratio of 1/10. Illite, dolomite, and quartz amounting to 67 percent of the original graywacke, were converted to albite and smectite. The rock gained Na and released Ca, K, heavy metals, and CO 2 to solution. In sharp contrast, the...
Automated determination of bromide in waters by ion chromatography with an amperometric detector
G. S. Pyen, D. E. Erdmann
1983, Analytica Chimica Acta (149) 355-358
An automated ion chromatograph, including a program controller, an automatic sampler, an integrator, and an amperometric detector, was used to develop a procedure for the determination of bromide in rain water and many ground waters. Approximately 10 min is required to obtain a chromatogram. The detection limit for bromide is...
SHALLOW HYDROTHERMAL SYSTEM AT NEWBERRY VOLCANO, OREGON: A CONCEPTUAL MODEL.
Edward A. Sammel
1983, Conference Paper, Transactions - Geothermal Resources Council
Investigations at Newberry Volcano, Oregon, have resulted in a satisfactory account of the shallow hydrothermal system, but have not indicated the nature of a possible geothermal reservoir. Hot springs in the caldera probably represent the return of circulating meteoric water, warmed at shallow depths by high conductive heat flow and...
An isolated population of small Canada geese on Kaliktagik Island, Alaska
Scott A. Hatch, Martha A. Hatch
1983, Wildfowl (34) 130-136
Recently we discovered that a small form of the Canada Goose Branta canadensis breeds on Kaliktagik Island, one of the Semidi Islands, about 80 km south of the Alaska Peninsula near longitude 157°W (Figure 1). The unexpected occurrence of geese on this oceanic island and the possibility that they are...
A Pleistocene diatomaceous clay and a pumiceous ash, Yolo County ( California).
R. W. Page, G.L. Bertoldi
1983, California Geology (36) 14-20
Discusses a diatomaceous clay of Pleistocene age, cored from 534-544ft, and a pumiceous ash found at a depth of 453ft in a test hole. Tests on the clay indicate that it is highly susceptible to compaction, and therefore, it could contribute, or perhaps has contributed, to land subsidence in the...
Earthquakes; January-February 1983
W. J. Person
1983, Earthquake Information Bulletin (USGS) (15) 150-156
A minor earthquake occurred in western Nevada on January 9 at 6:59 a.m. PST. The magnitude 3.8 earthquake was located about 16 miles west of Carson City. MM IV effects were noted at Minden. On February 16 at 12:21 a.m. and February 23 at 3:10 a.m. PST, minor earthquakes occurred in...
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,...
Can the earth be dated from decay of its magnetic field?.
G. B. Dalrymple
1983, Journal of Geological Education (31) 124-133
Thomas G. Barnes, Emeritus Professor of Physics at the University of Texas, El Paso, and a creationist, argues that the geomagnetic field was created by unknown processes at the time of creation of the earth and has been decaying irreversibly and exponentially, with a half-life of about 1400 years,...
Correlation of metal occurrence and terrane attributes in the northwestern conterminous United States
E. W. Tooker
1983, Canadian Journal of Earth Sciences (20) 1030-1039
The regional distribution patterns for 20 critical metals derived by an areal-pattern recognition technique leads me to conclude that metals are regularly distributed preferentially in the accreted and cratonic terranes studied in and surrounding the state of Oregon in the northwestern United States. The distribution patterns along distinctively different zones...
