Scientists probe Earth’s secrets at the Hawaiian Volcano Observatory
J. D. Unger
1974, Earthquake Information Bulletin (USGS) (6) 3-11
The Hawaiian Volcano Observatory (HVO) sits on the edge of Kilauea Caldera at the summit of Kilauea Volcao, one of the five volcanoes on the island of Hawaii, the largest island in the Hawaiian Islands chain. Of the five, only Kilauea and Mauna Loa have been active in the past...
Gas-liquid chromatographic determination of 3-trifluoromethyl-4-nitrophenol residues in fish
J. L. Allen, J.B. Sills
1974, Journal of the Association of Official Analytical Chemists (57) 387-388
A procedure for the determination of 3-trifluormethyl-4-nitrophenol (TFM) in fish tissues is described. Homogenized tissues are extracted with hexane-ethyl ether; the extract is cleaned up by partitioning the TFM from the extracting solvent into 0.1N NaOH, acidifying the aqueous solution, and partitioning again with hexaneethyl ether. The TFM is methylated with...
Oxygen isotope activities and concentrations in aqueous salt solutions at elevated temperatures: Consequences for isotope geochemistry
A.H. Truesdell
1974, Earth and Planetary Science Letters (23) 387-396
Studies of the effect of dissolved salts on the oxygen isotope activity ratio of water have been extended to 275°C. Dehydrated salts were added to water of known isotope composition and the solutions were equilibrated with CO2 which was sampled for analysis. For...

Earthquake prediction; new studies yield promising results
R. Robinson
1974, Earthquake Information Bulletin (USGS) (6) 14-17
On Agust 3, 1973, a small earthquake (magnitude 2.5) occurred near Blue Mountain Lake in the Adirondack region of northern New York State. This seemingly unimportant event was of great significance, however, because it was predicted. Seismologsits at the Lamont-Doherty geologcal Observatory of Columbia University accurately foretold the time, place,...
Age, growth, sexual maturity, and food of channel catfish in central Lake Oahe, 1968-69
Victor J. Starostka, William R. Nelson
1974, Technical Paper 81
Channel catfish, Ictalurus punctatus, were collected with gill nets, trawl, and trap nets at three localities in Lake Oahe for the study of year-class strength, growth in length and weight, age composition, sexual maturity, and food. Fish were recruited to all the collection gears at age II. Relatively strong year...
Myxosoma cerebralis: Comparative sensitivity of spore detection methods
M.E. Markiw, K. Wolf
1974, Journal of the Fisheries Research Board of Canada (31) 1597-1600
Physical and biophysical methods of detecting spores of Myxosoma cerebralis were used in sequence on 87 individual fingerling rainbow trout (Salmo gairdneri) from two populations with a low incidence of infection. Physical methods of releasing spores from the organs of equilibrium, gill arches, or the axial skeleton gave an estimated rate of...

An antigenic comparison between infectious hematopoietic necrosis virus (OSV strain) and the virus of haemorrhagic septicaemia of rainbow trout (Salmo gairdneri) (Denmark strain) by cross neutralization
P. E. McAllister, J. L. Fryer, K.S. Pilcher
1974, Journal of Wildlife Diseases (10) 101-103
The infectious hematopoietic necrosis virus (OSV strain) and the virus of haemorrhagic septicaemia of rainbow trout (Salmo gairdneri) (Denmark strain) were examined for possible antigenic relationship by plaque neutralization using homologous and heterologous antisera. No neutralization of either virus was observed on exposure to heterologous antiserum. This indicates that there...
The role of lava erosion in the formation of lunar rilles and Martian channels
M. H. Carr
1974, Icarus (22) 1-23
Lava tubes and channels develop around active sources of low viscosity lava. The channels normally form without erosion; however, sustained flow can result in the incision of a lava channel and simulation of fluvial erosion features. Lava erosion by means of thermal incision...
An experimental trap net fishery, Lake Oahe, South Dakota, 1965
James A. Gabel
1974, Technical Paper 82
Large trap nets were evaluated as a commercial gear for capturing buffalo fish during July-September 1965. During the 72-day fishing period, 13,171 fish weighing 21,669 kg were taken. Bigmouth buffalo (Ictiobus cyprinellus) and smallmouth buffalo (Ictiobus bubalus) dominated the catch (78.2% by weight). Eight sport species accounted for 3.6% of...
A geologic and geophysical study of the Charleston, South Carolina, earthquake zone
B.B. Higgins, P. Popenoe
1974, Earthquake Information Bulletin (USGS) (6) 16-23
A maximum Modified Mercalli intensity of X was reported in Charleston. Damage to buildings was extensive, railroads were made impassable, and communications were disrupted. During the earthquake 27 people were killed, and 56 later died as a result of exposure and injuries sustained during the shaking. The earthquake was reported...

Porosity, density, grain density, and related physical properties of sediments from the Red Sea drill cores
Frank T. Manheim, Linda Dwight, Rebecca A. Belastock
1974, Initial reports of the Deep Sea Drilling Project (23) 887-907
Representative sediments from each site were chosen for examination of their dry specific gravity and grain density. The determinations were made by micropycnometer; water was used as the displacing medium, and salt corrections were based on the refractive index measurements on interstitial water. For saltier brines the "salinities" derived from...
Stable isotope and lead isotope study of the Cortez, Nevada, gold deposit and surrounding area
R. O. Rye, B. R. Doe, J. D. Wells
1974, Journal of Research of the U.S. Geological Survey (2) 13-23
Isotope studies of sulfur, carbon, hydrogen, oxygen, and lead were carried out to clarify the age and origin of the Cortex gold deposit and the surrounding mineralized area. The hydrogen isotope data indicate that meteoric water was the dominant component of the ore-forming fluids at Cortez. The hydrogen isotope data support geologic evidence for a...
