Interstitial water studies on small core samples from the Mediterranean Sea
F.L. Sayles, L.S. Waterman, F.T. Manheim
1973, Initial reports of the Deep Sea Drilling Project (13) 801-808
Of ten Leg 13 sites studied by us, eight give definite evidence of the existence of halite-containing sediments beneath the seabed. This conclusion is based on the existence on continuous sodium and chloride enrichments in interstitial waters with depth. This is the only direct evidence of the existence of salt...
Late Quaternary sedimentation in the active eastern Aleutian Trench
David J. W. Piper, Roland von Huene, John R. Duncan
1973, Geology (1) 19-22
Sediments originally deposited on the Alaskan Abyssal Plain have been depressed to form the eastern Aleutian Trench. Simultaneously, a wedge of horizontally bedded sediments, about 1 km thick at its axis, has been deposited in the trench. The time-transgressive facies change between this wedge of sediment and the abyssal-plain sediment...
Granitic rocks of the White Mountains area, California-Nevada: Age and regional significance
Dwight F. Crowder, Edwin H. McKee, Donald C. Ross, Konrad Krauskopf
1973, Geological Society of America Bulletin (84) 285-296
Potassium-argon ages have been determined on 25 biotite and hornblende samples (four coexisting biotite-hornblende pairs were dated) from a number of granitic formations in the more than 500 sq mi of dominantly granitic outcrop in the White Mountains. These new data, together with earlier published radiometric ages, indicate a group...
Species diversity: Patterns in modern and Miocene foraminifera of the eastern margin of North America
Thomas G. Gibson, Martin A. Buzas
1973, Geological Society of America Bulletin (84) 217-238
Patterns of foraminiferal species diversity were examined along the eastern margin of North America by utilizing the number of species, S, the information function, H(S), and species equitability, E. The 350 modern samples we studied extended from the Arctic to the Gulf of Mexico at depths ranging from a few...
Ground-water data for Michigan
Water Resources Division, U.S. Geological Survey
1973, Report, Geological Survey (U.S.). Water Resources Division: Summary of ground-water hydrologic data in Michigan

Use of ground water for irrigation in Seward County, Nebraska in 1971
Eugene K. Steele Jr.
1973, Open-File Report 7308
Use of ground water for irrigation in Seward County west of the Big Blue River increased tremendously from 1945 to 1971. During that period, the number of irrigation wells increased from 5 to 614. Ground-water withdrawals prior to 1971 are estimated to have reduced ground-water storage by about 270,000 acre-feet,...
Water records of the U.S. Virgin Islands, 1962-69
Tully M. Robinson
1973, Report
The surface-water, quality of water, and ground-water records of the Virgin Islands from 1962 through 1969 are presented in this report. The location of all stations in this report are shown on the individual island maps. Each island map is followed by the tabulation of water records for that island....
Land subsidence due to ground-water withdrawal Arvin-Maricopa area, California
Ben Elder Lofgren
1973, Report
The Arvin-Maricopa area is the southernmost of three principal areas of widespread subsidence in the San Joaquin Valley. As of 1970, 700 square miles of irrigable land, roughly 60 percent of the area, has subsided due to the intensive pumping of ground water. Maximum subsidence exceeds 9 feet, and the...
Timing of mesozoic and cenozoic plutonic events in circum-Pacific North America
Marvin A. Lanphere, Bruce L. Reed
1973, GSA Bulletin (84) 3773-3782
Evaluation of isotopic ages of granitic intrusive rocks of large batholiths in circum-Pacific North America indicates that Mesozoic and Cenozoic plutonism was episodic but not periodic. Three intrusive epochs have been defined in the Alaska-Aleutian Range batholith of Alaska on the basis of...
Mathematical simulation of temperatures in deep impoundments: verification tests of the Water Resources Engineers, Inc. model - Horsetooth and Flaming Gorge Reservoirs
D.L. King, Jim J. Sartoris
1973, Report
Successful use of predictive mathematical models requires verification of the accuracy of the models by applying them to existing situations where the prediction can be compared with reality. A Corps of Engineers' modification of a deep reservoir thermal stratification model developed by Water Resources Engineers, Inc., was applied to...
