Seasonal-to-interannual fluctuations in surface temperature over the Pacific: effects of monthly winds and heat fluxes Seasonal-to-interannual fluctuations in surface temperature over the Pacific: effects of monthly winds and heat fluxes
Monthly heat fluxes and wind stresses are used to force the Oberhuber isopycnic ocean general-circulation (OPYC) model of the Pacific basin over a two-decade period from 1970 to 1988. The surface forcings are constructed from COADS marine observations via bulk formulae. Monthly anomalies of the fluxes and stresses are superimposed upon model climatological means of these variables, which...

Waste burial in arid environments - Application of Information from a field laboratory in the Mojave Desert, Southern Nevada Waste burial in arid environments - Application of Information from a field laboratory in the Mojave Desert, Southern Nevada
Because of the potentially harmful effect of improper waste disposal on water resources in the arid West, comprehensive laboratory and field studies are critical to identifying likely contaminant-release pathways and the potential for waste migration at arid sites. However, the quandary for those charged with assessment of the suitability of potential disposal sites is that site...

Sewage contamination in the upper Mississippi River as measured by the fecal sterol, coprostanol Sewage contamination in the upper Mississippi River as measured by the fecal sterol, coprostanol
The molecular sewage indicator, coprostanol, was measured in bed sediments of the Mississippi River for the purpose of determining sewage contamination. Coprostanol is a non-ionic, non-polar, organic molecule that associates with sediments in surface waters, and concentrations of coprostanol in bed sediments provide an indication of long-term sewage loads. Because coprostanol...

The structural and geochemical evolution of the continental crust: Support for the oceanic plateau model of continental growth The structural and geochemical evolution of the continental crust: Support for the oceanic plateau model of continental growth
The problem of the origin of the continental crust can be resolved into two fundamental questions: (1) the location and mechanisms of initial mantle extraction of the primitive crust and (2) the processes by which this primitive crust is converted into the continental crust that presently exists. We know that Archean continental crust is compositionally distinct from younger continental...

Preliminary results from the hydrodynamic element of the 1994 entrapment zone study Preliminary results from the hydrodynamic element of the 1994 entrapment zone study
This article discusses preliminary results from analyses of USGS hydrodynamic data collected as part of the 1994 Interagency Ecological Program entrapment zone study. The USGS took part in three 30-hour cruises and deployed instruments for measuring currents and salinity from April to June. This article primarily focuses on the analysis of data from five Acoustic Doppler Current ProUers...

Diagnostic modeling of trace metal partitioning in south San Francisco Bay Diagnostic modeling of trace metal partitioning in south San Francisco Bay
The two-dimensional numerical model ELAmet was used to investigate the effect of adsorption kinetics on the apparent distribution coefficients of Cu, Cd, and Zn in south San Francisco Bay, California. The numerical experiments were designed to determine whether adsorption kinetics can control the basin-scale variability of the observed partitioning and to define the conditions under...

Data on selected herbicides and two triazine metabolites in precipitation of the Midwestern and Northeastern United States, 1990-91 Data on selected herbicides and two triazine metabolites in precipitation of the Midwestern and Northeastern United States, 1990-91
Weekly precipitation (rain and snow) samples were collected from 81 National Atmospheric Deposition Program/National Trends Network sites in the Midwestern and Northeastern United States for the analysis of herbicides. In addition, five high- elevation background sites along the Rocky Mountains and in Alaska were sampled to provide data on herbicides in precipitation at sites far from...
