Simulation model of Skeletonema costatum population dynamics in northern San Francisco Bay, California
A pseudo-two-dimensional model is developed to simulate population dynamics of one dominant phytoplankton species (Skeletonema costatum) in northern San Francisco Bay. The model is formulated around a conceptualization of this estuary as two distinct but coupled subsystems—a deep (10–20 m) central channel and lateral areas with shallow (<2 m) water and slow circulation. Algal growth rates are gove

Preliminary data from a series of artificial recharge experiments at Stanton, Texas
A series of artificial recharge experiments was conducted by the U.S. Geological Survey at an experimental site located in Stanton, Texas. Five tests were performed from March 1977 through December 1978 to: (1) Evaluate the hydraulic properties of the aquifer; (2) test sampling and monitoring equipment; (3) compare tracers for future use in hydrologic investigations; and (4) determine the radial a

Geochemical evidence for water‐rock interaction along the San Andreas and Garlock Faults of California
Mesozoic granitoid rocks adjacent to the San Andreas fault in central California have retained their radiogenic Ar for the last 70 m.y. but have, generally, the highest 18O and H2O+ contents and the lowest D contents of all the granitoid rocks in California. The geographical coincidence of the D, 18O, and H2O+ patterns with the present trace of the San Andreas fault leave little doubt that some ki

Holocene intertidal deposits of Sacramento-San Joaquin Delta, California: Abstract
Rivers draining nearly one third of California reach sea level in the Sacramento-San Joaquin delta. Though tapered toward a constricted outlet and separated from the sea by a chain of estuarine bays and straits, the delta resembles deltas built into open-marine environments in that (1) its principal landforms--tidal wetlands and natural levees--are typical features of such delta, and (2) the funda

Ground water resources of Lee County
Approximately 8.0 percent of the water used in Lee County comes from underground sources. It is estimated that the use of ground water in the county currently approaches 2.8 billion gallons per year. For comparison, this amount would provide each resident with 172 gallons of water a day during a year. Actually, few if any households use this much water, and this greater per capita use reflects the
