Status of the deepwater cisco population of Lake Michigan
Stanford H. Smith
1964, Transactions of the American Fisheries Society (93) 155-163
The species and size composition and the abundance of the cisco (Leucichthys spp.) population of Lake Michigan have undergone drastic changes since the sea lamprey became established in the 1940's. The changes were measured by the catches of gill nets of identical specifications fished at the same seasons, depths, and...
Life history of lake herring in Lake Superior
William R. Dryer, Joseph Beil
1964, Fishery Bulletin (63) 493-530
The average annual commercial catch of lake herring (Coregonus artedi) in U.S. waters of Lake Superior was nearly 12 million pounds in 1929-61. This production contributed 62.4 percent of the total U.S. take of lake herring for the Great Lakes. About 90 percent of the annual catch is...
Potassium-argon and lead-alpha ages of plutonic rocks, Bokan Mountain area, Alaska
M. A. Lanphere, E.M. MacKevett Jr., T. W. Stern
1964, Science (145) 705-707
Most of the granitic rocks in the Bokan Mountain area, southeastern Alaska, are early Paleozoic (probably Ordovician) judged by potassium-argon and lead-alpha age measurements. The Bokan Mountain Granite, the youngest intrusive unit in the area, belongs to a Mesozoic plutonic episode. These age measurements are the first direct evidence for...
Pentaborate polyanion in the crystal structure of ulexite, NaCaB5O6(OH)6*5H2O
Joan R. Clark, Daniel E. Appleman
1964, Science (145) 1295-1296
Triclinic ulexite crystals contain isolated borate polyanions [B5O6(OH)6]3- related to the well known pentaborate polyanion [B5O6(OH)4]- by addition of two hydroxyl groups to two opposite B-O triangles. The isolated ulexite polyanions form the [B5O7(OH)4]n3n- chains previously found in crystals of the related mineral probertite, NaCaB5O7(OH)4·3H2O....
Ancient granite gneiss in the Black Hills, South Dakota
R. E. Zartman, J.J. Norton, T. W. Stern
1964, Science (145) 479-481
Granite gneiss, with an age of approximately 2.5 billion years, in the Black Hills, South Dakota , provides a link betweeen ancient rocks in western Wyoming and Montana and in eastern North and South Dakota and Minnesota. The discovery suggests that early Precambrian rocks covered an extensive area in northcentral...
Igneous rocks of the East Pacific Rise
A.E.J. Engel, C.G. Engel
1964, Science (146) 477-485
The apical parts of large volcanoes along the East Pacific Rise (islands and seamounts) are encrusted with rocks of the alkali volcanic suite (alkali basalt, andesine- and oligoclase-andesite, and trachyte). In contrast, the more submerged parts of the Rise are largely composed of a tholeiitic basalt which has low concentrations...
Isotopic composition of lead and strontium from Ascension and Gough Islands
P.W. Gast, G.R. Tilton, C. Hedge
1964, Science (145) 1181-1185
Isotopic composition of lead and strontium has been determined in a series of rock samples from two islands on the Mid-Atlantic Ridge. Both inter-and intra-island variations exist in the abundance of radiogenic isotopes of both elements. Lead from basalt of Ascension Island has a Pb206-Pb 204 ratio of 19.5, while...
Distribution of narrow-width magnetic anomalies in Antarctica
John C. Behrendt
1964, Science (144) 993-999
Data for aeromagnetic profiles obtained in Antarctica during the 1963-64 austral summer were used together with earlier results to construct a map showing the areal distribution of narrow-width magnetic anomalies. Numerous anomalies are associated with known volcanic mountains in western Antarctica. A large area of few anomalies is probably a...
Infrared surveys of Hawaiian volcanoes
W. A. Fischer, R.M. Moxham, F. Polcyn, G.H. Landis
1964, Science (146) 733-742
Aerial infrared-sensor surveys of Kilauea volcano have depicted the areal extent and the relative intensity of abnormal thermal features in the caldera area of the volcano and along its associated rift zones. Many of these anomalies show correlation with visible steaming and reflect convective transfer of heat to the...
Ground-water reconnaissance in the Burnt River valley, Baker County, Oregon
Don Price
1964, Open-File Report 64-128
The Burnt River valley in southern Baker County, Oreg., is underlain by rocks that range in age from pre-Tertiary to Quaternary. The pre-Tertiary rocks consist mainly of argillites, schists, limestones, and intrusive igneous rocks, while the Tertiary rocks consist mainly of felsic and mafic volcanic tuffs, lava flows and breccias,...
[Book review] Politics and water resources
Luna Bergere Leopold
1964, Science (144) 402-403
Arizona is a state in which development has proceeded sufficiently rapidly relative to the available water supply that its water problems are as acute as those of nearly any other state in the Union. Owing to the fact that, in the past, the principal use of water was for irrigation,...
Fluvial processes in geomorphology
Luna Bergere Leopold, M. Gordon Wolman, John P. Miller
1964, Book
This excellent text is a pioneering work in the study of landform development under processes associated with running water. Its primary emphasis is on subjects that were the focus of the authors' studies in both field and laboratory. Part I deals with the process of change in the evolving landscape....
Developing a State Water Plan: A basic water resource data program for Utah
Ted Arnow, R.H. Langford, M. T. Wilson
1964, Cooperative Investigations Report 1
Reliable data on Utah's water resources are essential to development of a State Water plan. While the need for such data was outlined in the report entitles "Developing a State Water Plan - Utah's water resources, problems, and needs - A challenge" published by the Utah Water and Power Board...
Selected hydrologic data, upper Sevier River basin, Utah
Carl H. Carpenter, Gerald B. Robinson Jr., Louis Jay Bjorklund
1964, Utah Basic-Data Report 8
This report is intended to serve two purposes: (1) to make available to the public basic ground-water data useful in planning and studying development of water resources, and (2) to supplement an interpretive report that will be published later.Records were collected during 1961-63 by the U.S. Geological Survey in cooperation...
