A brief history of commercial fishing in Lake Erie
Vernon C. Applegate, Harry D. Van Meter
1970, Fishery Leaflet 630
Salient features of the development of the industry from about 1815 to 1968, changes in fishing gears and methods, changes in the kinds and abundance of fishes caught, and the attendant effects of disappearing species on the stability of the fishery are described. The history and present status of the...
An annotated list of the fishes of Lake Erie and its tributary waters exclusive of the Detroit River
Harry D. Van Meter, Milton B. Trautman
1970, Ohio Journal of Science (70) 65-78
Dramatic fluctuations have occurred in the abundance of many species in Lake Erie and its tributary waters in the last century. Some fishes of former economic importance have become commercially extinct. Several species apparently have been extirpated, especially in the tributaries. It is believed that further changes in the abundance...

This is a polygon coverage of the Land Resource Regions and Major Land Resource Areas of the conterminous United States. Land resource regions are geographic areas that are characterized by a particular pattern of soils, climate, water resources and land uses. (USDA, Soil Conservation Service, 1981). Major land...
The determination of low levels of cobalt-60 in environmental waters by liquid scintillation counting
H.C. Claassen
1970, Analytica Chimica Acta (52) 229-235
A method for determination of cobalt-60 in waters at levels greater than 0.5 pCi per sample is presented. A modification of the method may be used to analyze fluvial sediments and soils. After the cobalt has been separated, first as the hydroxide and then as...
Some investigations of the deposition of travertine from Hot Springs-I. The isotopic chemistry of a travertine-depositing spring
I. Friedman
1970, Geochimica et Cosmochimica Acta (34) 1303-1315
The isotopic compositions of the travertine and of the hot spring solutions were studied at Main Springs and New Highland Terrace in the Mammoth Hot Springs area of Yellowstone Park. The springs issue at 74°C and a pH of 6.65 and the carbon isotopic composition of the travertine depositing at...
Geothermal resources of the northern gulf of Mexico basin
P.H. Jones
1970, Geothermics (2) 14-26
Published geothermal gradient maps for the northern Gulf of Mexico basin indicate little or no potential for the development of geothermal resources. Results of deep drilling, from 4000 to 7000 meters or more, during the past decade however, define very sharp increases in geothermal gradient which are associated with the...
Isotopic composition of strontium in sea water throughout Phanerozoic time
Z. E. Peterman, C. E. Hedge, H. A. Tourtelot
1970, Geochimica et Cosmochimica Acta (34) 105-120
Isotopic analyses of strontium in primary fossil carbonate reveal significant variations in Sr87Sr86">Sr87Sr86 of sea water during the Phanerozoic. The strontium isotopic composition may have been uniform from the Ordovician through the Mississippian, with an average Sr87Sr86">Sr87Sr86 of 0.7078. A subsequent decrease...
Isotopic investigations of xenoliths and host basalts from the Honolulu volcanic series
J. R. O’Neil, C. E. Hedge, E.D. Jackson
1970, Earth and Planetary Science Letters (8) 253-257
Oxygen, carbon and strontium isotope ratios point to a ground-water origin for the carbonates found in Hawaiian Volcanic Series rocks. Strontium isotope ratios in the xenoliths and host basalts indicate a genetic relationship between them....

Photogeologic and thermal infrared reconnaissance surveys of the Los Negritos-Ixtlan de los Hervores geothermal area, Michoacan, Mexico
Valle R. Gomez, J. D. Friedman, S.J. Gawarecki, C.J. Banwell
1970, Geothermics (2)
New techniques, involving interpretation of panchromatic, ektachrome and ektachrome infrared aerographic photogaphs and thermographic infrared imagery recording emission from the earth's surface in middle and far infrared wavelengths (3–5μm and 8–14μm), are being introduced in geothermal investigations in Mexico to identify outstanding structural and geologic features in a rapid and...
Hydrologic research on instrumented watersheds
Luna Bergere Leopold
1970, Conference Paper, Colloque de Wellington Symposium, 1970, Results of Research on Representative and Experimental Basins (IASH Publication 97)
The successful research man is the one who asks himself the right question. Research must go on primarily in the mind and only secondarily in the physical and biological world. It is only too easy to confuse the choice of a proper tool and the choice of a proper question....

Toxicity of 33NCS (3'-chloro-3-nitrosalicylanilide) to freshwater fish and sea lampreys
Leif L. Marking, Everett L. King, Charles R. Walker, John H. Howell
1970, Investigations in Fish Control 38
The chemical 33NCS (3'-chloro-3-nitrosalicylanilide) was evaluated as a fish control agent and as a larvicide for sea lampreys at the Fish Control Laboratories of the Bureau of Sport Fisheries and Wildlife and the Hammond Bay Biological Station of the Bureau of Commercial Fisheries. The chemical is rapidly toxic to many...

Correction of bias in belt transect studies of immotile objects
David R. Anderson, R.S. Pospahala
1970, Journal of Wildlife Management (34) 141-146
Unless a correction is made, population estimates derived from a sample of belt transects will be biased if a fraction of, the individuals on the sample transects are not counted. An approach, useful for correcting this bias when sampling immotile populations using transects of a fixed width, is presented....
Testing of selected pharmacological agents for capturing waterfowl [Annual Progress Report]
D.R. Cline
1970, Report
The response of game-farm mallards (Frost strain) to seven pharmacological immobilizing agents was evaluated in Phase I of a planned four-phase study. A limited amount of testing was also done with wild mallards. Single dosages were administered to determine the mean effective dose (ED50) and mean lethal dose (LD50), The...
Waterfowl in relation to land use and water levels on the Spring Run Area
Gary L. Krapu, D.R. Parsons, M.W. Weller
1970, Iowa State Journal of Science (44) 437-452
Low water levels during critical phases of the breeding cycle appear to have caused population declines of waterfowl and other marsh birds on the Spring Run Game Management Area. Pair-counts indicated a decline from 70 pairs of waterfowl in 1965 to 2 pairs in 1968. Nest success of upland nesting...
