Volcanoes
Robert I. Tilling
1982, Report
Volcanoes destroy and volcanoes create. The catastrophic eruption of Mount St. Helens on May 18, 1980, made clear the awesome destructive power of a volcano. Yet, over a time span longer than human memory and record, volcanoes have played a key role in forming and modifying the planet upon which...

The nomenclatural enigma of single versus double -i endings for scientific patronyms emended to represent a man's name: A comment and some considerations
M.R. Jennings
1982, Fisheries (7) 9-10
The current inconsistency over the use of single vs. double -i endings for singular masculine scientific patronyms in official lists of scientific names of fishes causes needless confusion and labor. Taxonomists once preferred rules for Latinization calling for double -i endings, but current rules suggest single -i endings. Recent rulings by the International Commission of Zoological...

JoanH Fellers, Gary M. Fellers
1982, Pacific Science (36) 427-437
The Crater District of Haleakala National Park was surveyed for ants. Three species were found. Argentine ants (Iridomyrmex humilis) occurred only within I km of the park headquarters and the nearby research facility. Hypoponera opaciceps was found in small numbers throughout the Crater District. Cardiocondyla emeryi was present only at...
USGS aerial resolution targets.
P.H. Salamonowicz
1982, Photogrammetric Engineering and Remote Sensing (48) 1469-1473
It is necessary to measure the achievable resolution of any airborne sensor that is to be used for metric purposes. Laboratory calibration facilities may be inadequate or inappropriate for determining the resolution of non-photographic sensors such as optical-mechanical scanners, television imaging tubes, and linear arrays. However, large target arrays imaged...
The solubilities of calcite, aragonite and vaterite in CO2-H2O solutions between 0 and 90°C, and an evaluation of the aqueous model for the system CaCO3-CO2-H2O
Niel Plummer, Eurybiades Busenberg
1982, Geochimica et Cosmochimica Acta (46) 1011-1040
Calculations based on approximately 350 new measurements (CaT-PCO2) of the solubilities of calcite, aragonite and vaterite in CO2-H2O solutions between 0 and 90°C indicate the following values for the log of the equilibrium constants KC, KA, and KV respectively, for the reaction CaCO3(s) = Ca2+ + CO2−3: <img...

Cyclic deposits containing hummocky cross-stratification occur in the upper part of the Cape Sebastian Sandstone of Bourgeois (1980), a shallow marine transgressive sandstone of Late Cetaceous age on the southern Oregon coast. The cycles average 1.6 m in thickness and consist, where complete,...
Alewives and rainbow smelt in Lake Huron: midwater and bottom aggregations and estimates of standing stocks
Ray L. Argyle
1982, Transactions of the American Fisheries Society (111) 267-285
The continued availability of adequate amounts of forage fish, primarily alewives Alosa pseudoharengus and rainbow smelt Osmerus mordax, is critical to the success of ongoing programs aimed at rebuilding lake trout Salvelinus namaycush populations and maintaining other salmonid stocks in Lake Huron. These forage species are distributed at middepths as...
Petrology and trace element geochemistry of the Honolulu volcanics, Oahu: Implications for the oceanic mantle below Hawaii
D.A. Clague, F.A. Frey
1982, Journal of Petrology (23) 447-504
The Honolulu Volcanics comprises small volume, late-stage (post-erosional) vents along rifts cutting the older massive Koolau tholeütic shield on Oahu, Hawaii. Most of these lavas and tuff of the Honolulu Volcanics have geochemical features expected of near-primary magmas derived from a peridotite source containing Fo87–89 olivine; e. g. 100 Mg/(Mg...
Computation with physical values from Landsat digital data
C.J. Robinove
1982, Photogrammetric Engineering and Remote Sensing (48) 781-784
Landsat digital images are commonly analyzed by using the digital numbers for each pixel recorded on a computer-compatible magnetic tape. Although this procedure may be satisfactory when only a single, internally consistent image is used, the procedure may produce incorrect results if more than one image is used for analysis...
The modified polyconic projection for the IMW
John P. Snyder
1982, Cartographica: The International Journal for Geographic Information and Geovisualization (19) 31-43
The modified Polyconic map projection designed by Lallemand and adopted for the International Map of the World between 1909 and 1962 has two meridians and two parallels which are true to scale. Constructed geometrically in the past, forward and inverse coordinate transformations may be calculated analytically in order to transfer...
Simulations of seabird damage and recovery from oilspills in the northern Gulf of Alaska.
W.B. Samuels, K.J. Lanfear
1982, Journal of Environmental Management (15) 169-182
If an oilspill contacts a colony of glaucous-winged gulls Larus hyperboreus, reducing the population by 50%, the population is expected to recover to its pre-spill level in c.20 yr. For common murres Uria aalge, this same situation yields a recovery time of c.70 yr. Assuming that oil is found in...
Applications of Landsat imagery to problems of petroleum exploration in Qaidam Basin, China
G. B. Bailey, P. D. Anderson
1982, American Association of Petroleum Geologists Bulletin (66) 1348-1354
Tertiary and Quaternary nonmarine, petroleum-bearing sedimentary rocks in the Qaidam basin of remote western China have been extensively deformed by compressive forces. These forces created many folds which are current targets of Chinese exploration programs. Manual techniques of image analysis and interpretation were applied to computer-enhanced Landsat images of the...

Exotic terranes of western California
M.O. McWilliams, D. G. Howell
1982, Nature (297) 215-217
Numerous distinct geological terranes compose the North American Cordillera1; there may be as many as 50 terranes in California alone2. Critical to deciphering the history of Cordilleran tectonic assembly is an understanding of the displacement history of individual terranes. It is therefore important to know: (1) whether a terrane has...
