Kenneth J. Englund
G. Briggs, editor(s)
1974, Book chapter, Carboniferous of the southeastern United States
The Pocahontas Formation is a clastic wedge of sandstone, siltstone, shale, coal, and underclay that is transitional between underlying marine strata of Mississippian age and overlying continental beds of Pennsylvanian age. It attains a maximum thickness of 750 ft. at the southeastern edge of the Appalachian coal field and thins...

Water-management studies of a stream-aquifer system, Arkansas River Valley, Colorado
O. James Taylor, Richard R. Luckey
1974, Groundwater (12) 22-38
A mathematical model was developed and used to simulate the stream-aquifer system in the Arkansas River valley in southeastern Colorado, from Pueblo to the Colorado-Kansas State line. The model simulates the interrelations among ground water and surface water including reservoirs, losses, and transmountain diversions, utilizing various water-distribution rules. The model...

A note on costs of collecting hydrometric flow data in the United States
W. B. Langbein, G. E. Harbeck Jr.
1974, Hydrological Sciences Bulletin (19) 227-229
Information for comparing costs of collecting hydrometric data in different countries may promote efficiency of operations. The hydrometric programme in the United States consists of 8400 full-record stations and an equal number of partial-record stations operated by 47 district offices. A sampling of four districts selected to represent the range...
Determination of selenium in water
M. Lansford, E. M. McPherson, Marvin J. Fishman
1974, Atomic Absorption Newsletter (13) 103-105
The determination of selenium by hydride generation atomic absorption spectrophotometry using zinc is widely used. Very little is mentioned, however, on possible interferences. In an attempt to use this technique for the determination of selenium in natural waters, interferences were found. The most serious interference occurred when arsenic was present....

Isotopic composition of carbon and hydrogen in some Apollo 14 and 15 lunar samples
Irving Friedman, Kenneth G. Hardcastle, Jim D. Gleason
1974, Journal of Research of the U.S. Geological Survey (2) 7-12
Isotopic composition of carbon and hydrogen in some Apollo 14 and 15 lunar samples was determined by use of a newly constructed combustion line that yields low blanks for CO2 and H2. The results from combustion of fines and breccia from Apollo 14 lunar samples and of fines, breccia, and basalt from Apollo 15...
Control of the sea lamprey (Petromyzon marinus) in Lake Superior, 1953-70
Bernard R. Smith, J. James Tibbles, B. G. H. Johnson
1974, Technical Report 26
The sea lamprey (Petromyzon marinus) gained entrance into Lake Superior in the early 1940's, and began making drastic inroads on the fish stocks by the early 1950's. Serious efforts to control the parasite began in 1953 with the installation of electrical barriers in streams to block spawning runs. Control measures...
Movement and recapture of parasitic-phase sea lampreys (Petromyzon marinus) tagged in the St. Marys River and Lakes Huron and Michigan, 1963-67
Harry H. Moore, Frederick H. Dahl, Aarne K. Lamsa
1974, Technical Report 27
Recoveries of 477 (11.8%) of 4,048 tagged parasitic-phase sea lampreys showed that lampreys moved extensively and that interchange between the Great Lakes was common. Of 93 recoveries from 2,265 tagged lampreys released below the navigation locks in the St. Marys River, 80 were in Lake Huron, 12 in Lake Superior,...

Life history of the spottail shiner (Notropis hudsonius) in southeastern Lake Michigan, the Kalamazoo River, and western Lake Erie
LaRue Wells, Robert House
1974, Research Report 78
In southeastern Lake Michigan spottail shiners in samples ranged from ages 0 to V, but most were in age groups I-IV. In the Kalamazoo River (a tributary of southeastern Lake Michigan) age group II was commonest in the catches, and no fish older than age IV were sampled. In western...
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...

Effects of stocking density and water exchange rate on growth and survival of channel catfish Ictalurus punctatus (Rafinesque) in circular tanks
Kenneth O. Allen
1974, Aquaculture (4) 29-39
Channel catfish were cultured for 177 days in circular tanks containing 1.6 m3 of water at combinations of five stocking densities (90–720 fish/m3) and five water exchange rates (2.0–0.5 h per exchange). Net yield increased as stocking density increased up to 540 fish/m3 then declined at higher densities. Mean fish weight, feed...
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...
