E.M. Shoemaker, N. G. Bailey, R. M. Batson, D.H. Dahlem, T.H. Foss, M. J. Grolier, E. N. Goddard, M. H. Hait, H. E. Holt, K.B. Larson, J. J. Rennilson, G. G. Schaber, D. L. Schleicher, H.H. Schmitt, R. L. Sutton, G.A. Swann, A. C. Waters, M.N. West
1969, Book chapter, Apollo 11 preliminary science report (NASA SP-214)
The Apollo 11 LM landed approximately 20 km south-southwest of the crater Sabine D in the southwestern part of Mare Tranquillitatis ( fig. 3-1 ). The landing site is 41.5 km north-northeast of the western promontory of the Kant Plateau (ref. 3-1 ), which is the nearest highland region. The...
Analog-digital models of stream-aquifer systems
E. A. Moulder, C.T. Jenkins
1969, Report
The best features of analog and digital computers were combined to make a management model of a stream-aquifer system. The analog model provides a means for synthesizing, verifying, and summarizing aquifer properties; the digital model permits rapid calculation of the effects of water management practices. Given specific management alternatives, a...
Water resources data for California, 1968; Part 1: Surface water records; Volume 1: Colorado River Basin, Southern Great Basin, and Pacific Slope Basins excluding Central Valley
Water Resources Division, U.S. Geological Survey
1969, Water Data Report CA-68-1-1
The surface-water records for the 1968 water year for gaging stations, partial-record stations, and miscellaneous sites within California are given in this report. For convenience, also included are records for a few pertinent gaging stations in bordering States. The records were collected and computed by the Water Resources Division of...

Hydrogeologic data for the southwestern coastal river basins, Connecticut
Mendall P. Thomas, Robert B. Ryder, Chester E. Thomas Jr.
1969, Connecticut Water Resources Bulletin 18
This report presents hydrologic and geologic data collected by the U.S. Geological Survey during an investigation of water resources in the southwestern coastal river basins of Connecticut in cooperation with the Connecticut Water Resources Commission. These basins occupy about 394 square miles in Connecticut and 46 square miles in New York, including the towns...
Our changing continent
Water Resources Division, U.S. Geological Survey
1969, Report
Where were the land areas and oceans of the North American Continent one million years ago, compared to our present geography? Was North America always about the same size and shape as it is today? To answer these questions, we must construct maps of the lands and sea that existed...
Chlorinated hydrocarbons in the young of Lake Michigan coho salmon
W. A. Willford, J.B. Sills, E.W. Whealdon
1969, Progressive Fish-Culturist (31) 220-220
Three thousand eyed coho salmon (Oncorhynchus kisutch) eggs from Lake Michigan stock were sent by the Department of Natural Resources to the Fish Control Laboratory, La Crosse, Wis., on January 15, 1969, for use in evaluating candidate fish-cnotrol chemicals....
Chemical composition of rainbow trout urine following acute hypoxic stress
Joseph B. Hunn
1969, Transactions of the American Fisheries Society (98) 20-22
Rainbow trout (Salmo gairdnerii) were anesthetized with MS-222, catheterized, and introduced into urine collecting chambers. Twenty-four hours after introduction, a 4-hour accumulation of urine was collected to serve as the control. Water flow to the chambers was then discontinued for 30 minutes during which the oxygen content of the water...
Determination of phosphate in natural waters by activation analysis of tungstophosphoric acid
Herbert E. Allen, Richard B. Hahn
1969, Environmental Science & Technology (3) 844-848
Activation analysis may be used to determine quantitatively traces of phosphate in natural waters. Methods based on the reaction 31P(n,γ)32P are subject to interference by sulfur and chlorine which give rise to 32P through n,p and n,α reactions. If the ratio of phosphorus to sulfur or chlorine is small, as...
