Change in methylene blue active substances and chloride levels in streams in Suffolk County, New York, 1961-1976
Stephen E. Ragone, August A. Guerrera, W.J. Flipse Jr.
1976, Open-File Report 76-600
Since 1961, concentrations of methylene blue active substances and chloride were measured in samples collected at 67 sampling stations on 44 streams in Suffolk County, Long Island, New York. Changes in the concentrations of these constituents and calculated chloride/methylene blue active substances ratios are reported. Although many factors--the 1962 to...

R.M. Slade Jr., J.M. Taylor
1976, Report
The U.S. Soil Conservation Service is actively engaged in the implementation of flood- and soil-erosion reducing measures in Texas under the authority of "The Flood Control Act of 1936 and 1944" and "Watershed Protection and Flood Prevention Act" (Public Law 566), as amended. The Soil Conservation Service has found that...

Temperature tolerance of young-of-the-year lake whitefish, Coregonus clupeaformis
Thomas A. Edsall, Donald V. Rottiers
1976, Journal of the Fisheries Research Board of Canada (33) 177-180
The ultimate upper lethal temperature of young-of-the-year lake whitefish, Coregonus clupeaformis, was 26.65 C; this value is closely similar to that reported for yearling bloaters,Coregonus hoyi (26.75 C) and young-of-the-year lake herring, Coregonus artedii (26.0 C)....

A land use and land cover classification system for use with remote sensor data
James R. Anderson, Ernest E. Hardy, John T. Roach, Richard E. Witmer
1976, Professional Paper 964
The framework of a national land use and land cover classification system is presented for use with remote sensor data. The classification system has been developed to meet the needs of Federal and State agencies for an up-to-date overview of land use and land cover throughout the country on a basis that is uniform...
Radiochemical monitoring of water after the Cannikin event, Amchitka Island, Alaska, August 1974 and chemical monitoring from July 1972 to June 1974
Wilbur C. Ballance, William Thordarson
1976, Report
Radiochemical data from the Arnchitka Island study area were obtained from water samples collected by the U.S. Geological Survey during August 1974. Tritium determinations were made on 18 samples, and gross alpha and gross beta/ gamma determinations were made on 12 samples. No appreciable differences were found between the data...

Geohydrology and water supply, Shemya Island, Alaska
Alvin John Feulner, Chester Zenone, K. M. Reed
1976, Open-File Report 76-82
Sheyma Island, Alaska, was occupied as a military base in 1942. Since that time, potable water has been supplied by streams, lakes, wells, and in the late 1950's, a gallery system. The island is a low-lying, wave-cut platform composed of pyroclastic and volcanic rocks with some intrusives. Bedrock is overlain...
Rapid determination of nanogram amounts of tellurium in silicate rocks
L. P. Greenland, E.Y. Campbell
1976, Analytica Chimica Acta (87) 323-328
A hydride-generation flameless atomic-absorption technique is used to determine as little as 5 ng g-1 tellurium in 0.25 g of silicate rock. After acid decomposition of the sample, tellurium hydride is generated with sodium borohydride and the vapor passed directly to a resistance-heated quartz cell mounted in an atomic-absorption spectrophotometer. Analyses...
Concretionary manganese-iron oxides in streams and their usefulness as a sample medium for geochemical prospecting
G.A. Nowlan
1976, Journal of Geochemical Exploration (6) 193-210
Correlation studies of 400 samples of sieved stream sediments and 325 samples of fluvial, concretionary Mn-Fe oxides from Maine resulted in the separation of elements into the following categories: (1) elements not scavenged by Mn-Fe oxides — B, Cr, K, Mg, Rb, Sc, Ti, V, and Zr; (2) elements...
Interactive computer programs for petrologic modeling with extended Q-mode factor analysis
A.T. Miesch
1976, Computers & Geosciences (2) 439-492
An extended form of Q-mode factor analysis may be used if the row-sums of the data matrix are constant and can be helpful especially in developing and testing petrologic-mixing models for igneous systems. The first step is to represent the sample compositions as unit vectors in M-dimensional space and then...
Optimum level of dietary biotin for growth, feed utilization, and swimming stamina of fingerling lake trout (Salvelinus namaycush)
H. A. Poston
1976, Journal of the Fisheries Research Board of Canada (33) 1803-1806
Triplicate lots of fingerling lake trout (Salvelinus namaycush) held at 9 C for 20 wk were fed a semipurified basal diet supplemented with 1% spray-dried egg white or d-biotin at concentrations of 0.1, 0.5, 1.0, or 5.0 ppm. Trout fed the basal diet, either alone or with egg white, grew more slowly and...
The national coal-resources data system of the U.S. geological survey
M.D. Carter
1976, Computers & Geosciences (2) 331-340
The National Coal Resources Data System (NCRDS) was designed by the U.S. Geological Survey (USGS) to meet the increasing demands for rapid retrieval of information on coal location, quantity, quality, and accessibility. An interactive conversational query system devised by the USGS retrieves information from the data bank through a standard...
Infection and mortality in captive wild-trapped canvasback ducks
R. M. Kocan, Matthew C. Perry
1976, Journal of Wildlife Diseases (12) 30-33
Fungal, bacterial and malarial infections, as well as malnutrition caused heavy mortality in a group of wild-trapped canvasbacks (Aythya valisineria) held in 10 × 3 × 2 m open water pens. Deaths occurred between 21 and 158 days after confinement and were associated...
