John W. Hodges
1972, Journal of the Fisheries Research Board of Canada (29) 1237-1240
After the Pere Marquette River was treated with a lampricide in May 1964, the number of recently transformed sea lampreys (Petromyzon marinus) collected in the water-intake structure of a chemical plant near the mouth of the stream dropped 99.5%, from 13,913 (average for 1962-63 and 1963-64) to 76 (average for...

I. G. Sohn, L.S. Kornicker
1972, Science (175) 1258-1259
An ostracod species of Cypretta is an effective predator in laboratory experiments on 1- to 3-day-old Biomphalaria glabrata, a vector snail of the blood fluke that causes the tropical and subtropical disease schistosomiasis....
Absolute stress measurements at the rangely anticline, Northwestern Colorado
R. V. de la Cruz, C.B. Raleigh
1972, International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts (9) 625-634
Five different methods of measuring absolute state of stress in rocks in situ were used at sites near Rangely, Colorado, and the results compared. For near-surface measurements, overcoring of the borehole-deformation gage is the most convenient and rapid means of obtaining reliable values for the...
New data on selected Ivory Coast tektites
F. Cuttitta, M. K. Carron, C. S. Annell
1972, Geochimica et Cosmochimica Acta (36) 1297-1309
Fourteen Ivory Coast tektites exhibit a range of bulk indices of refraction of 1.5156 to 1.5217 ± 0.0004 and of bulk specific gravities of 2.428 to 2.502 ±0.005. Seven of these Ivory Coast (IVC) tektites were analyzed for major and minor element content. Compared to tektites from other strewn fields,...
Graphical methods for representing form and stability of aqueous metal ions
J.D. Hem
1972, Chemical Geology (9) 119-132
The equilibrium distributions of solute species of aluminum at 25°C and one atmosphere pressure are shown graphically in systems containing fluoride, as functions of the total dissolved aluminum and fluoride. The predominant form of complex and degree of complexing are also shown...

Determination of total iodine and iodate in sea water and in various evaporites
M. M. Schnepfe
1972, Analytica Chimica Acta (58) 83-89
Iodine in sea water and evaporites is determined spectrophotometrically as the starch-iodine complex without prior separation or concentration of the iodine. In slightly alkaline solution, iodide is first oxidized to iodate with permanganate. Oxidized states of manganese are destroyed with iron(II) in phosphate medium...
Paleomagnetism of Midway Atoll lavas and northward movement of the Pacific plate

1972, Earth and Planetary Science Letters (17) 159-168
Two deep drill holes through the reef limestones of Midway Atoll penetrated 120 m and 19 m of basaltic lavas that were dated by the KAr method at 18 my. Inclinations of natural remanent magnetization have been measured...

Cloudburst floods in Utah, 1939-69
Elmer Butler, Ray E. Marsell
1972, Report
During 1939-69, 836 cloudburst floods were reported in Utah. The largest number was in 1965, when 88 floods were reported; 63 floods were reported in 1968, and 56 were reported in 1961. The smallest number of floods reported was three in 1944. In 1942, 1948, and 1950, six floods were...

Limnology and fish ecology of sockeye salmon nursery lakes of the world
Wilbur L. Hartman, R.L. Burgner
1972, Journal of the Fisheries Research Board of Canada (29) 699-715
Many important, recently glaciated oligotrophic lakes that lie in coastal regions around the northern rim of the Pacific Ocean produce anadromous populations of sockeye salmon, Oncorhynchus nerka. This paper describes the limnology and fish ecology of two such lakes in British Columbia, five in Alaska, and one in Kamchatka. Then...
Life history and production of walleyes of the 1959 year-class in western Lake Erie, 1959-62
John W. Parsons
1972, Transactions of the American Fisheries Society (101) 655-661
Because of the near collapse of the fishery for walleyes (Stizostedion vitreum vitreum) in Lake Erie in the late 1950's, walleyes of the 1959 year-class were studied to gain a better understanding of the life history of the species and the dynamics of the population. In the summer of 1959...
Lake Michigan: effects of exploitation, introductions, and eutrophication on the salmonid community
LaRue Wells, Alberton L. McLain
1972, Journal of the Fisheries Research Board of Canada (29) 889-898
Lake Michigan surface area is 22,400 square miles and its main depth is 276 ft. Its fauna is generally typical of North American oligotrophic lakes. The original fish populations included 10 coregonines and one salmonine. The lake whitefish, the lake herring, and the lake trout were most abundant. Man's activities...
Seasonal population characteristics of the opossum shrimp, Mysis relicta, in southeastern Lake Michigan, 1970-71
James B. Reynolds, G.M. DeGraeve
1972, Proceedings of the 15th Conference on Great Lakes Research (15) 117-131
This study of depth distribution, abundance, growth, reproduction and standing crop of the opossum shrimp, Mysis relicta, in southeastern Lake Michigan was based on monthly samples collected from August 1970 through July 1971 (except February and March). Population density was usually low at 10-20 fathoms, moderate at 25-30 fathoms and...

Water inflow into hole UA-1, Amchitka Island, Alaska
Wilbur C. Ballance, W.A. Beetem
1972, Report
Chemical composition of water samples, temperature of inflow water, and theoretical calculations were compared to evaluate the water-contributing intervals to the zone to be mined--1,782.8 to 1,798.6 meters (5,849 to 5,901 feet)--in hole UA-1, Amchitka Island, Alaska. Chemical composition and temperature of inflow water indicated the contributing zones to have...
Hydraulic tests in hole UAe-6h, Amchitka Island, Alaska
Wilbur C. Ballance
1972, Report
Inflatable straddle packers were used to isolate and test 14 intervals ranging from 39 to 258 meters (127 to 846 feet) each in hole UAe-6h. Packer seats were poor in part of the hole because of unstable wall conditions. Thus, some zones had to be tested several times. The static...
Destruction of the ecosystem in the Great Lakes and possibilities for its reconstruction
Stanford H. Smith
Remedios W. Moore, editor(s)
1972, Book chapter, Progress in fishery and food science
This paper is a review of the sequence of events within the Great Lakes and their drainage to provide a basis for interpreting probable cause-and-effect relations between events of settlement and changes in the ecosystem of the Great Lakes. Possibilities of restoration of the lakes are discussed. A plan to...
