Trace elements in Corbicula fluminea from the San Joaquin River, California
(i) Trace element concentrations in soft tissue of the benthic bivalve, Corbicula fluminea, from the San Joaquin River and its major tributaries were examined during the primary irrigation season in relation to the spatial variation in concentrations of major, minor and trace constituents in riverwater and sediments. (ii) Selenium concentrations in Corbicula from perennial flow reaches of the San

U.S. Geological Survey DLG-3 and Bureau of the Census TIGER data. Development and GIS applications
The U.S. Geological Survey has been actively developing digital cartographic and geographic data and standards since the early 1970's. One product is Digital Line Graph data, which offer a consistently accurate source of base category geographic information. The Bureau of the Census has combined their Dual Independent Map Encoding data with the Geological Survey's 1:100,000-scale Digital Line Grap

Underwater research methods for study of nuclear bomb craters, Enewetak, Marshall Islands
Three craters, created by the explosion of nuclear fusion devices, were mapped, sampled, core drilled and excavated with airlifts at Enewetak Atoll in the Marshall Islands by using scuba and a research submersible. The craters studied were Mike, Oak, and Koa. Tests took place near sea level at the transition between lithified reef flat and unlithified lagoonal sediments, where water depth ranged f

Uranium-series dating of secondary carbonates near Yucca Mountain, Nevada. Applications to tectonic, paleoclimatic, and paleohydrologic problems
Near-surface accumulations of secondary carbonates are common in the soils and sediments of the Yucca Mountain area. These carbonates contain small amounts of uranium that allow dating by the uranium-series disequilibrium method. Preliminary results from the Yucca Mountain area indicate that the U-series methods can (1) identify multiple episodes of tectonic fracturing, (2) provide a chronologic f

Urban hydrology in the desert, Antelope Valley, California
A study of urban hydrology in Antelope Valley includes data collection, analysis of rainfall and runoff frequencies, and comparison of results from various rainfall-runoff models. This paper discusses only parts of the project that include data collection and frequency analyses.
