RECENT DEVELOPMENTS ON THE ORIGIN OF MINERAL MATTER IN COAL.
C. B. Cecil, R.W. Stanton, F.T. Dulong, L.P. Ruppert
1983, Conference Paper
This study attempts to quantify some of the various origins of mineral matter. Data developed for the Upper Freeport coal bed indicates that mineral matter other than pyrite and calcite is primarily derived from the vegetal matter that ultimately became coal. Cathodoluminesence was used to verify that the quartz in...

Paleotemperature oscillations in the Middle and Late Miocene of the northeastern Pacific.
J.A. Barron, G. Keller
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...

Two examples of earthquake- hazard reduction in southern California.
W. J. Kockelman, C.C. Campbell
1983, Earthquake Information Bulletin (USGS) (15) 216-225
Because California is seismically active, planners and decisionmakers must try to anticipate earthquake hazards there and, where possible, to reduce the hazards. Geologic and seismologic information provides the basis for the necessary plans and actions. Two examples of how such information is used are presented. The first involves assessing the...
INTERACTIVE NAME PLACEMENT FOR PROVISIONAL MAPS.
Jeffrey L. Goldberg, Thomas C. Miller
1983, Conference Paper, Technical Papers of the American Congress of Surveying and Mapping
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....
Intensity patterns in eastern Asia.
J. F. Evernden
1983, Chinese Geophysics (2) 405-438
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...
COORDINATION OF DIGITAL CARTOGRAPHY IN THE FEDERAL GOVERNMENT.
K. Eric Anderson, Peter F. Bermel
1983, Conference Paper, Technical Papers of the American Congress of Surveying and Mapping
The development and application of digital cartographic data bases are significant and important activities in the Federal Government. Increasingly, digital spatial data are being used for computer-based analyses in support of management decisions on land, forests, minerals, and energy....
The past is the key to the future
B. R. Doe
1983, Geochimica et Cosmochimica Acta (47) 1341-1354
A new major frontier of geological research, which was initiated in the 1970's, involves predicting future geologic trends or events through study of the present and past, rather than trying to understand the past, often using what one knows about the present. Like most scientific frontiers, this one began from...
Nitrate concentrations under irrigated agriculture
A. Zaporozec
1983, Environmental Geology (5) 35-38
In recent years, considerable interest has been expressed in the nitrate content of water supplies. The most notable toxic effect of nitrate is infant methemoglobinemia. The risk of this disease increases significantly at nitrate-nitrogen levels exceeding 10 mg/l. For this reason, this concentration has been established as a limit for...

Mammoth Lakes earthquakes and ground uplift: precursors to possible volcanic activity ( USA)?
R. A. Bailey
1983, Earthquake Information Bulletin (USGS) (15) 88-101
Recent seismicity and ground uplift in the area are described. A comparison with other areas in the Cascades is made and the possibility of the Long Valley Magma Chamber as a source for eruptions is discussed. -P.N.Chroston...
Neoplasms identified in free-flying birds
Lynne M. Siegfried
1983, Avian Diseases (27) 86-99
Nine neoplasms were identified in carcasses of free-flying wild birds received at the National Wildlife Health Laboratory; gross and microscopic descriptions are reported herein. The prevalence of neoplasia in captive and free-flying birds is discussed, and lesions in the present cases are compared with those previously described in mammals and...
Water quality and the rotifer populations in the Atchafalaya River Basin, Louisiana
L. E. Holland, C.F. Bryan, J.P. Newman Jr.
1983, Hydrobiologia (98) 55-69
We compiled distributional and ecological information on the class Rotifera from both flood controlled and uncontrolled reaches of the Atchafalaya River Basin, a large river-swamp in the south-central United States. In the minimally altered lower basin a variety of aquatic habitats within a small area resulted...
Elevated DDE and toxaphene residues in fishes and birds reflect local contamination in the lower Rio Grande valley Texas USA
Donald H. White, C. A. Mitchell, H.R. Kennedy, A. J. Krynitsky, M. A. Ribick
1983, Southwestern Naturalist (28) 325-334
A potential organochlorine pesticide problem was identified near Mission, Texas, by the National Park Monitoring Program. Fish samples from this site have consistently contained elevated levels of DDE since 1968. Surveys were made in 1976, 1978, and 1979 to determine the extent of organochlorine pesticide contamination in fishes and birds...

Inclusion body disease of cranes: A serological follow-up to the 1978 die-off
D. E. Docherty, Renee I. Romaine
1983, Avian Diseases (27) 830-835
A herpesvirus was isolated from captive cranes involved in a 1978 die-off. Neutralizing antibody to this virus was detected in this captive population as early as 1975 and consistently thereafter through 1979. Exposure to the virus evidently occurred at least 2 1/2 years before the die-off, without causing any mortality...
Aspergillosis in a red-crowned crane
R. K. Stroud, R. M. Duncan
1983, Journal of the American Veterinary Medical Association (183) 1297-1298
An unusual form of pulmonary aspergillosis in a red-crowned crane (Grus japonensis) is described in this report. The major lesion is unique because it closely resembles a lesion referred to as an aspergilloma. An aspergilloma is a single large granulomatous lesion that resembles a tumor and is caused by fungi...

Selective control of common carp: Ineffectiveness of 2-(digeranylamino)-ethanol (GD-174) in pond trials
P.A. Gilderhus, R.M. Burress
1983, North American Journal of Fisheries Management (3) 61-66
The candidate piscicide, 2‐(digeranylamino)‐ethanol, (commonly known as GD‐174) was subjected to efficacy trials in ponds under a wide variety of conditions. Results of the trials were disappointing considering that laboratory tests had shown the compound to be selectively toxic to common carp (Cyprinus carpio). Results of pretreatment, on‐site toxicity tests...
