Quality assurance practices for the chemical and biological analyses of water and fluvial sediments
Linda C. Friedman, David E. Erdman
1981, Open-File Report 81-650
This chapter contains practices used by the U.S. Geological Survey to assure the quality of analytical data for water, fluvial sediment, and aquatic organisms.These practices are directed primarily toward personnel making water-quality measurements. Some detail specific quality control techniques, others document quality assurance procedures being used by the Central Laboratories...
Catalog of earthquakes along the San Andreas fault system in Central California, October-December 1977
L. Fluty, S.M. Marks
1981, Open-File Report 81-1325
Numerous small earthquakes occur each day in the Coast Ranges of central California. The detailed study of these earthquakes provides a tool for gaining insight into the tectonic and physical processes responsible for the generation of damaging earthquakes. This catalog contains the fundamental parameters for earthquakes located within and adjacent...

Water resources of the Santa Ysabel and Mesa Grande Indian Reservations, San Diego County, California
John R. Freckleton
1981, Open-File Report 81-342
The Santa Ysabel (consisting of three tracts) and Mesa Grande Indian Reservations are in north-central San Diego County, Calif. On both reservations fractured and weathered igneous and metamorphic rocks and alluvium are water bearing; however, no wells are known to derive their water entirely from alluvium. Well yields range from...

Single-channel seismic-reflection profiles and sidescan-sonar records collected on Georges Bank
David C. Twichell
1981, Open-File Report 81-438
Subbottom seismic-reflection, echo-sounding, and sidescan-sonar records were collected by the U.S. Geological Survey during two cruises over Georges Bank aboard the R/V OCEANUS (cruise 056, March 6-15, 1979 and cruise 067, August 6-13, 1979) (fig. 1). The data collected during these two cruises contributed to a study of bed-form types...

Generalized altitude and configuration of the base of the High Plains regional aquifer, northwestern Oklahoma
John S. Havens
1981, Open-File Report 81-1117
During 1978, the U.S. Geological Survey began a 5-year study of the High Plains regional aquifer system to provide hydrologic information for evaluation of the effects of long-term development of the aquifer and to develop computer models for prediction of aquifer response to alternative changes in ground-water management (Weeks, 1978)....
