The influence of nitrogen on heterocyst production in blue-green algae
Roann E. Ogawa, John F. Carr
1969, Limnology and Oceanography (14) 342-351
A series of experiments on heterocyst production in Anabaena variabilis provides some strong indirect evidence for the role of heterocysts in nitrogen fixation. Of the algae tested (Anabaena variabilis, A. inaequalis, A. cylindrica, A. flos-aquae, Tolypothrix distorta, Gloeotrichia echinulata, Aphanizomenon flos-aquae, Oscillatoria sp., and Microcystis aeruginosa), only those with heterocysts...
Critical review of some multivariate procedures in the analysis of geochemical data
A.T. Miesch
1969, Journal of the International Association for Mathematical Geology (1) 171-184
Simulation experiments have been conducted to examine the potential usefulness of R-mode and Q-mode factor methods in the analysis and interpretation of geochemical data. The R-mode factor analysis experiment consisted of constructing a factor model, using the model to generate a correlation matrix, and attempting to...
The killing efficiency of soft iron shot
R. Andrews, J. R. Longcore
1969, Transactions of the North American Wildlife and Natural Resources Conference (34) 337-345
A cooperative research effort between the ammunition industry and the Bureau of Sport Fisheries and Wildlife is aimed at finding a suitable non-toxic substitute for lead shot. A contract study by an independent research organization evaluated ways of coating or detoxifying lead shot or replacing it with another metal. As...

C.S. Robbins, W.T. Van Velzen
1969, Special Scientific Report - Wildlife 124
In the Breeding Bird Survey of North America, cooperators ran 982 survey routes in 1967 and 1,174 in 1968. All States except Hawaii and all Canadian Provinces except Newfoundland were included. Roadside routes are selected at random within 1-degree blocks of latitude and longitude. Each 24 1/2-mile route, with 3-minute...
Blood protozoa of free-living birds
C. M. Herman
Archibald McDiarmid, editor(s)
1969, Book chapter, Diseases in free-living wild animals: the proceedings of a symposium held at the Zoological Society of London on 9 and 10 May 1968
Blood protozoa were first reported from wild birds in 1884. Since then numerous surveys throughout the world have demonstrated their presence in a wide variety of hosts and localities with continuing designations of new species. Taxonomic determinations include parasites in the genera Plasmodium, Haemoproteus, Leucocytozoon, Babesia, Lankesterella and Trypanosoma....
Optical method for determining particle sizes of coarse sediment
John R. Ritter, Edward J. Helley
1969, Techniques of Water-Resources Investigations 05-C3
A particle-size analyzer was used to determine particle sizes of sediment by an optical technique based on an adjustable circle of light which determines the intermediate axis of the sediment particles shown on a photograph. Data from counting particles in various size ranges can be presented either in the form...
Estuarine studies in upper Grays Harbor, Washington
Joseph P. Beverage, Milton N. Swecker
1969, Water Supply Paper 1873-B
Improved management of the water resources of Grays Harbor, Wash., requires more data on the water quality of the harbor and a better understanding of the influences of industrial and domestic wastes on the local fisheries resources. To provide a more comprehensive understanding of these influences, the U.S. Geological Survey...
Stage-discharge characteristics of a Weir in a sand-channel stream
Don D. Gonzalez, C.H. Scott, James K. Culbertson
1969, Water Supply Paper 1898-A
A unique relation between water-surface elevation and water discharge usually does not exist for sand-channel streams. The relation is affected by changes in bed roughness and changes in bed elevation because of scour and fill. An artificial control on a sand-channel stream must control both the resistance to flow and...
Variations in low-water streambed elevations at selected stream-gaging stations in northwestern California
John J. Hickey
1969, Water Supply Paper 1879-E
Graphs and a table are presented showing the variations in streambed elevations that have occurred over the years in the low-water channels at selected gaging stations in northwestern California. The streambed elevations are calculated from data obtained during discharge measurements. The greatest elevation changes that were recorded occurred between the...

Claude W. Johnson, Leonard W. Browden, Robert W. Pease
1969, Open-File Report 71-158
Interpretation results of the small scale ClR photography of the Imperial Valley (California) taken on March 12, 1969 by the Apollo 9 earth orbiting satellite have shown that world wide agricultural land use mapping can be accomplished from satellite ClR imagery if sufficient a priori information is available for the...
Ground-water resources of the Wind River Indian Reservation, Wyoming
Laurence J. McGreevy, Warren Gayler Hodson, Samuel J. Rucker IV
1969, Water Supply Paper 1576-I
The area of this investigation is in the western part of the Wind River Basin and includes parts of the Absaroka, Washakie, Wind River, and Owl Creek Mountains. The purposes of the study were to determine the general hydrologic properties of the rocks in the area and the occurrence and...
Measurement of discharge by the moving-boat method
George F. Smoot, Charles E. Novak
1969, Techniques of Water-Resources Investigations 03-A11
This chapter describes the procedures for measuring discharge in large streams by the moving-boat technique. During the traverse of a boat across a stream, a sonic sounder records the geometry of the cross section, and a continuously operating current meter senses the combined stream and boat velocities. These data are...
Laboratory theory and methods for sediment analysis
Harold P. Guy
1969, Techniques of Water-Resources Investigations 05-C1
The diverse character of fluvial sediments makes the choice of laboratory analysis somewhat arbitrary and the pressing of sediment samples difficult. This report presents some theories and methods used by the Water Resources Division for analysis of fluvial sediments to determine the concentration of suspended-sediment samples and the particle-size distribution...
Hydrogeology of the Scioto River Valley near Piketon, south-central Ohio
Stanley Eugene Norris, Richard E. Fidler
1969, Water Supply Paper 1872
A systematic study was made of one of Ohio's principal aquifers, a sand and gravel outwash in the Scioto River Valley, to determine the feasibility of developing a ground-water supply of 20 million gallons per day at a site near Piketon. The first part of the study was spent in...
Hydrogeologic information on the Glorieta Sandstone and the Ogallala Formation in the Oklahoma Panhandle and adjoining areas as related to underground waste disposal
James Haskell Irwin, Robert B. Morton
1969, Circular 630
The Oklahoma Panhandle and adjacent areas in Texas, Kansas, Colorado, and New Mexico have prospered because of the development of supplies of fresh water and of oil and gas. The Ogallala and, in places, Cretaceous rocks produce fresh water for irrigation, public supply, and domestic and stock use through approximately...
Quantitative comparison of some aesthetic factors among rivers
Luna Bergere Leopold
1969, Circular 620
It is difficult to evaluate the factors contributing to aesthetic or nonmonetary aspects of a landscape. In contrast, aspects which lend themselves to cost-benefit comparisons are now treated in a routine way. As a result, nonmonetary values are described either in emotion-loaded words or else are mentioned and thence forgotten.The...
Scientific or rule-of-thumb techniques of ground-water management--Which will prevail?
Charles Lee McGuinness
1969, Circular 608
Emphasis in ground-water development, once directed largely to quantitatively minor (but sociologically vital) service of human and stock needs, is shifting: aquifers are treated as possible regulating reservoirs managed conjunctively with surface water. Too, emphasis on reducing stream pollution is stimulating interest in aquifers as possible waste-storage media. Such management...
Establishment of gold-quartz standard GQS-1
Hugh T. Millard, John Marinenko, John E. McLane
1969, Circular 598
A homogeneous gold-quartz standard, GQS-1, was prepared from a heterogeneous gold-bearing quartz by chemical treatment. The concentration of gold in GQS-1 was determined by both instrumental neutron activation analysis and radioisotope dilution analysis to be 2.61?0.10 parts per million. Analysis of 10 samples of the standard by both instrumental neutron...
