Expendable bubble tiltmeter for geophysical monitoring
J.A. Westphal, M.A. Carr, W.F. Miller, D. Dzurisin
1983, Review of Scientific Instruments (54) 415-418
An unusually rugged highly sensitive and inexpensive bubble tiltmeter has been designed, tested, and built in quantity. These tiltmeters are presently used on two volcanoes and an Alaskan glacier, where they continuously monitor surface tilts of geological interest. This paper discusses the mechanical, thermal, and electric details of the meter,...
Influence of the Onion Creek salt diapir on the late Cenozoic history of Fisher Valley, southeastern Utah
Steven M. Colman
1983, Geology (11) 240-243
More than 140 m of upper Cenozoic basin-fill sediments were deposited and then deformed in Fisher Valley between about 2.5 and 0.25 m.y. ago, in response to uplift of the adjacent Onion Creek salt diapir. In addition to these basin-fill sediments, minor amounts of eolian and fluvial sand were deposited...
Kinetic analysis of strontium and potassium sorption onto sands and gravels in a natural channel
Kenneth E. Bencala, Alan P. Jackman, Vance C. Kennedy, Ronald J. Avanzino, Gary W. Zellweger
1983, Water Resources Research (19) 725-731
A kinetic, first-order mass transfer model was used to describe the sorption of strontium onto sand- and gravel-sized streambed sediments. Rate parameters, empirically determined for strontium, allowed for the prediction of potassium sorption with moderate success. The model parameters varied significantly with particle size. The sorption data were collected during...
Clay mineral formation and transformation in rocks and soils
D. D. Eberl
1983, Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences (311) 241-257
Three mechanisms for clay mineral formation (inheritance, neoformation, and transformation) operating in three geological environments (weathering, sedimentary, and diagenetic-hydrothermal) yield nine possibilities for the origin of clay minerals in nature. Several of these possibilities are discussed in terms of the rock cycle. The mineralogy of clays neoformed in the weathering...
Research note: Isolation of a herpesvirus from a bald eagle nestling
D. E. Docherty, R.I. Romaine, R.L. Knight
1983, Avian Diseases (27) 1162-1165
Cloacal swabs collected from wild bald eagle nestlings (Haliaeetus leucocephalus) were tested for viruses. A virus isolated from one of these samples had a lipid coat and contained DNA. Electron microscopy confirmed that it was a herpesvirus. This appears to be the first report of a herpesvirus isolation from a...
VARIATIONS IN MINERAL MATTER CONTENT OF A PEAT DEPOSIT IN MAINE RESTING ON GLACIO-MARINE SEDIMENTS.
Cornelia C. Cameron, Paul Schruben
1983, Conference Paper, Los Alamos National Laboratory (Report) LA
The Great Heath, Washington County, Maine, is an excellent example of a multidomed ombrotrophic peatland resting on a gently undulating surface of glacio-marine sediments and towering above modern streams. A comprehensive study sponsored by the Geological Survey of Maine in cooperation with the U. S. Geological Survey included preparation of...
Gravity studies in the Cascade Range
Carol A. Finn, David Williams
1983, Conference Paper, Transactions - Geothermal Resources Council
A compatible set of gravity data has been compiled for the entire Cascade Range. From this data set a series of interpretive color gravity maps have been prepared, including a free air anomaly map, Bouguer anomaly map at a principle, and an alternate reduction density, and filtered and derivative versions...
Major and trace elements in Mahogany zone oil shale in two cores from the Green River Formation, piceance basin, Colorado
M. L. Tuttle, W.E. Dean, N. L. Parduhn
1983, Conference Paper, Preprints Symposia
The Parachute Creek Member of the lacustrine Green River Formation contains thick sequences of rich oil-shale. The richest sequence and the richest oil-shale bed occurring in the member are called the Mahogany zone and the Mahogany bed, respectively, and were deposited in ancient Lake Uinta. The name "Mahogany" is derived...
Hafnium isotope results from mid-ocean ridges and Kerguelen
Patchett P. Jonathan
1983, LITHOS (16) 47-51
176Hf/177Hf ratios are presented for oceanic volcanics representing both extremes of the range of mantle HfNdSr isotopic variation. Hf from critical mid-ocean ridgebasalts shows that 176Hf/177Hf does indeed have a greater variability than 143Nd/144Nd and 87Sr/86Sr in the depleted mantle. This extra variation is essentially of a random nature, and...
Geochemistry of diverse basalt types from Loihi Seamount, Hawaii: Petrogenetic implications
F.A. Frey, D.A. Clague
1983, Earth and Planetary Science Letters (66) 337-355
The wide variety of basalt types, tholeiitic to basanite, dredged from Loihi Seamount have minor and trace element abundances that are characteristic of subaerial Hawaiian basalts, thereby confirming that Loihi Seamount is a manifestation of the Hawaiian “hot spot”. Within the Loihi sample suite there are well-defined positive correlations among...
The nature of carbon dioxide waters in Snaefellsnes, western Iceland
S. Arnorsson, I. Barnes
1983, Geothermics (12) 171-176
Over 20 occurrences of thermal and non-thermal waters rich in carbon dioxide are known in the Snaefellsnes Peninsula of western Iceland. On the basis of the thermal, chemical and isotopic characteristics of these waters, and hydrological considerations, it is concluded that they represent meteoric waters which have seeped to variable...

Observations of emperor geese feeding at Nelson Lagoon, Alaska
Margaret R. Petersen
1983, The Condor (85) 367-368
Estuaries along the north side of the Alaska Peninsula provide essential habitat for most of the American population of Emperor Goose (Chen canagica) during migration (Petersen and Gill 1982). Most of the population passes through Nelson Lagoon in spring and fall, with over 40,000 birds recorded there (Gill et al...
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...
Detection of infectious hematopoietic necrosis virus in river water and demonstration of waterborne transmission
Daniel M. Mulcahy, Ronald J. Pascho, C.K. Jenes
1983, Journal of Fish Diseases (6) 321-330
In a study of the possible role of waterborne infectious haematopoietic necrosis virus in transmission of the disease among spawning sockeye salmon, Oncorhynchus nerka (Walbaum), both infection rates and virus titres were higher in fish held at high density in a side channel than in fish in the adjacent river....

Off-road vehicular destabilization of hill slopes: the major contributing factor to destructive debris flows in Ogden, Utah, 1979
John K. Nakata
Robert H. Webb, Howard G. Wilshire, editor(s)
1983, Book chapter, Environmental Effects of Off-Road Vehicles
The Wasatch Mountains in northern Utah are a north-south trending range with steep slopes caused by faulting less than 10,000 years ago. Through the natural processes of rain, frost-wedging, gravity, and earthquakes these slopes are slowly being eroded. A geologic history of instability is recorded at the base of the...
Surveyors, cartographers, photogrammetrists; identification friends or foes
Frederick J. Doyle
1983, Cartography (13) 88-95
Largely because of historical developments, the disciplines of geodesy, surveying, photogrammetry, cartography and remote sensing which make up the profession of cartographic science are organised into numerous societies at both the national and international levels. Partly as a consequence of this separatism, an effective education system for the profession is...

NEW HORIZONS FOR THE NATIONAL HIGH-ALTITUDE PHOTOGRAPHY PROGRAM.
Peter F. Bermel
1983, Conference Paper
The National High-Altitude Photography Program (NHAP) is a multi-Federal agency activity to acquire uniform imagery for the establishment of a national high-altitude photographic data base. Since the inception of NHAP in 1980, black-and-white and color infrared stereoscopic imagery has been acquired for about 50% of the 3,000,000 square miles in...
