EFFECT OF AN ACID RAIN ENVIRONMENT ON LIMESTONE SURFACES.
Victor G. Mossotti, James R. Lindsay, Michael F. Hochella Jr.
1987, Materials Performance (26) 47-52
Salem limestone samples were exposed to weathering for 1 y in several urban and one rural environments. Samples exposed in the rural location were chemically indistinguishable from the freshly quarried limestone, whereas all samples collected from urban exposure sites developed gypsum stains on the ground-facing surfaces where the stones were...
Vapor pressures and gas-film coefficients for ketones
R. E. Rathbun, D. Y. Tai
1987, Chemosphere (16) 69-78
Comparison of handbook vapor pressures for seven ketones with more recent literature data showed large differences for four of the ketones. Gas-film coefficients for the volatilization of these ketones from water determined by two different methods were in reasonable agreement....

On the interpretation of the geomagnetic energy spectrum
E.R. Benton, L.R. Alldredge
1987, Physics of the Earth and Planetary Interiors (48) 265-278
Two recent high-degree magnetic energy spectra, based mostly on MAGSAT data, are compared and found to agree very well out to order and degree n = 15, but the spectrum remains somewhat uncertain for higher degrees. The hypothesis that a primary break in the slope of the spectrum, plotted semi-logarithmically,...

R. M. Pollastro, C. L. Pillmore
1987, Journal of Sedimentary Petrology (57) 456-466
The Cretaceous-Tertiary (K-T) boundary is preserved in a sequence of coal-bearing, fluvial rocks in the lower part of the Raton Formation (Late Cretaceous and Paleocene) at several sites in the east-central part of the Raton Basin. The K-T boundary occurs at the top...

Pat S. Chavez Jr., Jeffrey A. Anderson, James W. Schoonmaker Jr.
1987, Conference Paper, Oceans Conference Record (IEEE)
Advances in digital image processing of the (GLORIA) Geological Long-Range Induced Asdic) sidescan-sonar image data have made it technically and economically possible to map large areas of the ocean floor including the Exclusive Economic Zone. Software was written to correct both geometric and radiometric distortions that exist in the original...

An oxygen isotope model for interpreting carbonate diagenesis in nonmarine rocks (Green River Basin, Wyoming, USA)
W. W. Dickinson
1987, Chemical Geology (65) 103-116
A closed-system model is used for predicting the δ18O of formation waters in the deep portions of the northern Green River basin, Wyoming. δ18Ocalcite is calculated from this modeled water and compared with the δ18O of measured calcites to help interpret diagenesis in the basin.The modification of 18Owater, which may be caused...
Quaternary silicic pyroclastic deposits of Atitlán Caldera, Guatemala
William I. Rose Jr., Christopher G. Newhall, Theodore J. Bornhorst, Stephen Self
1987, Journal of Volcanology and Geothermal Research (33) 57-80
Atitlán caldera has been the site of several silicic eruptions within the last 150,000 years, following a period of basalt/andesite volcanism. The silicic volcanism began with 5–10 km3 of rhyodacites, erupted as plinian fall and pyroclastic flows, about 126,000 yr. B.P. At 85,000 yr. B.P. 270–280 km3 of compositionally distinct rhyolite was...

Phytoplankton productivity in relation to light intensity: A simple equation
D. H. Peterson, M.J. Perry, K.E. Bencala, M.C. Talbot
1987, Estuarine, Coastal and Shelf Science (24) 813-832
A simple exponential equation is used to describe photosynthetic rate as a function of light intensity for a variety of unicellular algae and higher plants where photosynthesis is proportional to (1-e−β1). The parameter β (=Ik−1">=Ik−1) is derived by a simultaneous curve-fitting method, where I is incident...
Kinetic theory of oxygen isotopic exchange between minerals and water
R.E. Criss, R. T. Gregory, H.P. Taylor Jr.
1987, Geochimica et Cosmochimica Acta (51) 1099-1108
Kinetic and mass conservation equations are used to describe oxygen isotopic exchange between minerals and water in "closed" and open hydrothermal systems. In cases where n coexisting mineral phases having different reaction rates are present, the exchange process is described by a system of n + 1 simultaneous differential equations...
Management of midges and other invertebrates for waterfowl wintering in California
N.H. Euliss Jr., G. Grodhaus
1987, California Fish and Game (73) 238-243
A review of recent waterfowl food habit studies showed that invertebrates are of major dietary importance to ducks wintering in California. However current wetland practices are directed at production of plant foods and seldom consider the propagation of invertebrates. We suggest that invertebrate repopulation of seasonally flooded marshes will occur...

C. A. Faanes
1987, Prairie Naturalist (19) 209-220
Populations and distribution of breeding birds occupying wooded draws were studied in a five-county region of western North Dakota during June 1982. Wooded draw vegetation was dominated by green ash, which occurred in 96% of the draws sampled. Chokecherry and juneberry were the most frequent shrub species. I recorded 49...

Ned H. Euliss Jr., Stanley W. Harris
1987, Journal of Wildlife Management (51) 724-732
The feeding ecology of northern pintails (Anas acuta) and green-winged teal (A. crecca) was examined from October through February 1979-81 in 4 major seasonal marsh types in the Central Valley, California. The esophagi of 262 pintails contained 72.3% plant seeds and 27.7% animal matter. The esophagi of 173 green-winged teal...
The importance of methane and thiosulfate in the metabolism of the bacterial symbionts of two deep-sea mussels
C.R. Fisher, J.J. Childress, R.S. Oremland, R.R. Bidigare
1987, Marine Biology (96) 59-71
Undescribed hydrocarbon-seep mussels were collected from the Louisiana Slope, Gulf of Mexico, during March 1986, and the ultrastructure of their gills was examined and compared to Bathymodiolus thermophilus, a mussel collected from the deep-sea hydrothermal vents on the Gala??pagos Rift in March 1985. These closely related mytilids both contain abundant...
An inexpensive device for recording animal behavior
Craig R. Ely
1987, Wildlife Society Bulletin (15) 264-265
Recording animal behavior is tedious and time consuming when behaviors are recorded on tape and transcribed to data sheets. Data loggers circumvent these problems, but can be prohibitively expensive and may require extensive programming (see Hensler et al. [1986]). I describe an inexpensive, efficient alternative for recording behavioral observations....
Sanctuaries for lake trout in the Great Lakes
Jon G. Stanley, Randy L. Eshenroder, Wilbur L. Hartman
1987, Conference Paper, Coastal zone '87 : proceedings of the Fifth Symposium on Coastal and Ocean Management
Populations of lake trout, severely depleted in Lake Superior and virtually extirpated from the other Great Lakes because of sea lamprey predation and intense fishing, are now maintained by annual plantings of hatchery-reared fish in Lakes Michigan, Huron, and Ontario and parts of Lake Superior. The extensive coastal areas of...

Donald W. Schloesser, Bruce A. Manny, Charles L. Brown, Eugene Jaworski
1987, Conference Paper, Color aerial photography in the plant sciences and related fields : proceedings of the Tenth Biennial Workshop on Color Aerial Photography in the Plant Sciences
The feasibility of using low-altitude aerial photography to identify beds of submersed macrophytes is demonstrated. True color aerial photos and collateral ground survey information for submersed aquatic macrophyte beds at 10 sites in the St.Clair-Detroit River system were obtained in September 1978. Using the photos and collateral ground survey information,...
