Utilization of Skylab (EREP) system for appraising changes in continental migratory bird habitat
E.A. Work Jr., D.S. Gilmer
1975, Technical Report CR-147542
The author has identified the following significant results. Surface water statistics using data obtained by supporting aircraft were generated. Signature extraction and refinement preliminary to wetland and associated upland vegetation recognition were accomplished, using a selected portion of the aircraft data. Final classification mapping and...
Variation in response of channel catfish to Henneguya sp. infections (Protozoa: Myxosporidea)
J. P. McCraren, M.L. Landolt, G. L. Hoffman, F. P. Meyer
1975, Journal of Wildlife Diseases (11) 2-7
Infections in channel catfish (Ictalurus punctatus, Rafinesque) induced by the sporozoan Henneguya (Protozoa: Myxosporidea) result in seven known and diverse disease manifestations. Most outstanding is an interlamellar branchial form responsible for significant losses among immature catfish, and a unique papillomatous form. The question of whether or not the species of Henneguya involved in these...

Canister cryogenic system for cooling germanium semiconductor detectors in borehole and marine probes
G. R. Boynton
1975, Nuclear Instruments and Methods (123) 599-603
High resolution intrinsic and lithium-drifted germanium gamma-ray detectors operate at about 77–90 K. A cryostat for borehole and marine applications has been designed that makes use of prefrozen propane canisters. Uses of such canisters simplifies cryostat construction, and the rapid exchange of canisters...
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...

Peritidal lithologies of Cambrian carbonate islands, Carrara Formation, southern Great Basin
Robert B. Halley
1975, Book chapter, Tidal deposits: a casebook of recent examples and fossil counterparts
The Carrara Formation is a heterogeneous sequence of quartzites, siltstones, shales, limestones, dolostones, and mixed terrigenous-carbonate rocks. It is Early and Middle Cambrian in age (Stewart, 1970; Palmer, 1971). Figure 32-1 illustrates the general distribution of Carrara lithologies along a transect approximately normal to depositional strike (Fig. 32-2). The formation...
Effects of agricultural burning on nesting waterfowl
E.K. Fritzell
1975, Canadian Field-Naturalist (89) 21-27
Agricultural burning in an intensively farmed region within Manitoba's pothole district is shown to affect the nesting activities of ground-nesting ducks. All species, except Blue-winged Teal (Anas discors), preferred unburned nest cover, although success was higher in burned areas, where predators may have exerted less influence. Attitudes of farmers, burning...
Renal excretion in coho salmon (Oncorhynchus kisutch) after acute exposure to 3-trifluoromethyl-4-nitrophenol
J. B. Hunn, J. L. Allen
1975, Journal of the Fisheries Research Board of Canada (32) 1873-1876
Coho salmon (Oncorhynchus kisutch) exposed to an acute, sublethal concentration of 3-trifluoromethyl-4-nitrophenol (TFM) exhibited an increased output of urine when compared with controls, but the urinary excretion of Na, K, Ca, Mg, and Cl was not affected. About 35 times more conjugated TFM than free TFM was excreted during 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...
Heavy minerals in stream sands of the southern Hazara District, Pakistan
Karl W. Stauffer
1975, Open-File Report 75-360
The areal distribution of heavy minerals in 99 samples from stream sands in the southern Hazara District, West Pakistan, indicates that the metamorphic grade of the rocks in the area increases toward the northwest. Minerals of potential economic value in the heavy-mineral samples include scheelite from the Oghi-Batgram-Battal area and...

Use of palynological zones defined by Brenner and Doyle from the Cretaceous outcrop belt in Maryland, Delaware, and New Jersey permit correlation of the Cretaceous section in four wells drilled to basement in the Salisbury Embayment in the Eastern Shore of Maryland and in Accomack Co., Virginia. These correlations, supplemented...
