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...
The spottail shiner in Lower Red Lake, Minnesota
Lloyd L. Smith Jr., Robert H. Kramer
1964, Transactions of the American Fisheries Society (93) 35-45
On the basis of 14,564 spottail shiners (Notropis hudsonius) from Red Lakes, Minnesota, growth rates, strength of year classes, and food utilization were studied. Males and females had different body-scale relationships, and females grew faster than males. There was high correlation between water temperature and growth rate. Strength of year...
Bottom sediments of Saginaw Bay, Michigan
Leonard E. Wood
1964, Journal of Sedimentary Petrology (34) 173-184
Saginaw Bay is a southwest extension of Lake Huron on the east shore of the Southern Peninsula of Michigan. It is a shallow-water derivative of the Pleistocene Lake Saginaw. Sixty-one bottom samples were collected on a semigrid pattern and analyzed physically. Findings were treated statistically. Sediments range in size from...
Age and growth of the round whitefish in Lake Michigan
Donald Mraz
1964, Transactions of the American Fisheries Society (93) 46-52
The round whitefish, though rarely abundant, is widely distributed in northern waters. It is one of the least studied of the coregonines; the present report is but the second for Great Lakes waters. Commercial production in Lake Michigan has been tightly confined to the northern portion. The period 1924-30 showed...
Geology and ground-water conditions of Clark County, Washington, with a description of a major alluvial aquifer along the Columbia River
Maurice John Mundorff
1964, Water Supply Paper 1600
This report presents the results of an investigation of the ground-water resources of the populated parts of Clark County. Yields adequate for irrigation can be obtained from wells inmost farmed areas in Clark County, Wash. The total available supply is sufficient for all foreseeable irrigation developments. In a few local...
Chemical characteristics of south-central Lake Huron
Herbert E. Allen
1964, Conference Paper, Proceedings of the 8th Conference on Great Lakes Research
Water samples were collected for chemical analysis during eight cruises of the U.S. Bureau of Commercial Fisheries M/V CISCO in south-central Lake Huron in June-October 1956. Temperature, pH, conductivity, and the concentrations of Na+, K+, Ca++, C1-, SO4-, SiO2, and dissolved oxygen were determined for 233 samples from stations at...
Catalytic determination of vanadium in water
M. J. Fishman, M. W. Skougstad
1964, Analytical Chemistry (36) 1643-1646
A kinetic determination of V(V) as a catalyst was spectrophotometrically performed by using the indicator reaction of Gallamine blue (GB+) and bromate at pH 2.0. The reaction was followed by measuring absorbance change for a fixed-time of 3 min at 537 nm. The variables such as reagent...
Equilibrium of talc with enstatite and quartz
R. A. Robie
1964, Science (143) 1057-1057
A thermodynamic calculation of the vapor pressure of H20 in equilibrium with talc gives pH2O of one atmosphere at 718° ± 15°K in contradiction...
Submicroscopic spherules and color of tektites
A. N. Thorpe, F. E. Senftle
1964, Geochimica et Cosmochimica Acta (28)
Magnetic susceptibility measurements of 18 tektites from various strewn fields have been made as a function of temperature from 77°K to room temperature. A relatively large temperature-independent component of the magnetic susceptibility was observed in all cases, and an analysis of the data...
Cenomanian (Cretaceons) Foraminifera from the Puerto Rico Trench
R. Todd, D. Low
1964, Deep-Sea Research and Oceanographic Abstracts (11) 391-393
An assemblage of predominantly planktonic Foraminifera is discussed from rocks of Cenomanian age dredged from between 3,200 and 3,500 fm on the north slope of the Puerto Rico Trench. Thirty-three planktonic and benthonic species are described. Planomalina pulchella is new; nine species are specifically...
