Calculated geochronology and stress field orientations along the Hawaiian chain
E.D. Jackson, H. R. Shaw, K.E. Bargar
1975, Earth and Planetary Science Letters (26) 145-155
A new method has been discovered for calculating ages of the main shield building stages of volcanoes along the Hawaiian chain from Kilauea to the Hawaiian-Emperor bend. The method is based on a graphical technique for hypothetical subtraction of distance intervals that...
Mercury distribution in ancient and modern sediment of northeastern Bering Sea
C.H. Nelson, D.E. Pierce, Kam Leong, F.F.H. Wang
1975, Marine Geology (18) 91-104
Reconnaissance sampling of surface and subsurface sediment to a maximum depth of 80 m below the sea floor shows that typical values of 0.03 p.p.m. and anomalies of 0.2-1.3 p.p.m. mercury have been present in northeastern Bering Sea since Early Pliocene time. Values are highest in modern beach (maximum 1.3...
Dynamics of turbidity plumes in Lake Ontario
Edward J. Pluhowski
1975, Open-File Report 75-249
Large-turbidity features along the 275-kilometre long south shore of Lake Ontario were analyzed using LANDSAT-1 images. The ESIAC system developed by the Stanford Research Institute, was used to obtain enlargements and false-color renditions of turbidity plumes. After projection on a video screen, individual turbidity features were analyzed, mapped, and photographed.The...
Interstitial solutions and diagenesis in deeply buried marine sediments: Results from the Deep Sea Drilling Project
F.L. Sayles, F.T. Manheim
1975, Geochimica et Cosmochimica Acta (39) 103-127
Through the Deep Sea Drilling Project samples of interstitial solutions of deeply buried marine sediments throughout the World Ocean have been obtained and analyzed. The studies have shown that in all but the most slowly deposited sediments pore fluids exhibit changes in composition upon burial. These changes can be grouped...
Amino acid supplementation of casein in diets of Atlantic salmon (Salmo salar) fry and of soybean meal for rainbow trout (Salmo gairdneri) fingerlings
G. L. Rumsey, H. G. Ketola
1975, Journal of the Fisheries Research Board of Canada (32) 422-426
Fry of Atlantic salmon (Salmo salar) fed a diet containing isolated fish protein grew significantly faster than those fed a diet containing casein without supplemental amino acids, and had improved feed conversion and lower mortality. Supplementing the casein diet with essential amino acids to the levels in the isolated fish...
Bacterial diseases of fishes: Diagnostic procedures for gram-negative pathogens
E. B. Shotts Jr., G. L. Bullock
1975, Journal of the Fisheries Research Board of Canada (32) 1243-1247
A diagnostic scheme employing 10 media, 4 reagents, and 5 specific antiserums has been devised for identification of gram-negative pathogens of fishes. The scheme is not intended for detailed speciation of organisms, but for generic identification of organisms associated with infected fishes. Diagnosis can be accomplished in 24 h with selective...
Productivity and flowering of winter ephemerals in relation to Sonoran Desert shrubs
William L. Halvorson, Duncan T. Patten
1975, American Midland Naturalist (93) 311-319
Ephemeral plant biomass and density on a Sonoran Desert hill near Cave Creek, Arizona, vary relative to shrub canopy type and shrub density. Higher shrub density associated with increased elevation appears to decrease both ephemeral biomass productivity and density, while ephemeral growth is enhanced under a shrub canopy if it...
Thoracic collapse as affected by the retia thoracica in the dolphin
Clifford A. Hui
1975, Respiration Physiology (25) 63-70
The carcass of a subadult female Delphinus was placed in a hyperbaric chamber and subjected to two simulated dives each equivalent to 69.7 m. In one dive the thorax was in its natural state, and in the other 100 ml of water had been injected into each pleural cavity. Various morphometric...
Fluorescent antibody identification and detection of the Corynebacterium causing kidney disease of salmonids
G. L. Bullock, H. M. Stuckey
1975, Journal of the Fisheries Research Board of Canada (32) 2224-2227
An indirect fluorescent antibody technique (FAT) has been developed for serological identification, diagnosis of kidney disease (KD), and detection of subclinical infections of KD. Rabbit or goat antikidney disease serum and appropriately labeled immunoglobulin was found to be specific for the KD bacterium. The technique was superior to examination of...
Mineral resource models and the Alaskan Mineral Resource Assessment Program
Donald A. Singer
W. A. Vogely, editor(s)
1975, Book chapter, Mineral materials modeling A state-of-the-art review
The least exacting demand that can be made of any model is that it serves as a device whereby we can predict actual physical happenings. Another demand which could be made is that the physical happenings predicted be in some way relevant to man, either by allowing him to anticipate...
