First posted March 7, 2023 For additional information, contact: Geology, Energy & Minerals Science CenterU.S. Geological SurveyMail Stop 95412201 Sunrise Valley DriveReston, VA 20192Email: [email protected] As the United States transitions away from fossil fuels, its economy will rely on more renewable energy. Because current energy sources sometimes produce variable power supplies, it ...
Geologic processes strongly influence water and sediment quality in aquatic ecosystems but rarely are geologic principles incorporated into routine biomonitoring studies. We test if elevated concentrations of metals in water and sediment are restricted to streams downstream of mines or areas that may discharge mine wastes. We surveyed 198 catchments classified as "historically mined" or "unmine...
The southern continental margin-slope area of the South China Sea is a complex passive margin with diverse tectonic structures and movements. This rich in gas hydrate resources also an high incidence potential geological hazards. Identifying understanding submarine hazards this very important for disaster prevention management during future exploration development marine resources. In paper, fi...
Dynamic imaging provides an effective way to integrate previous time-lapse data with current data in order to estimate a current model. We present two methods useful for continuous dynamic reservoir and subsurface monitoring. The first method is a stochastic method for the inversion of geophysical data. It uses the ensemble Kalman filter (EnKF) that we demonstrate using time-lapse surface seism...
Existence of heavy minerals in waters in some regions causes serious environmental pollution and affects the soil and water resources quality. Soil and waters sensitive to pollutants were investigated in this research, based on the degree of sensitivity of their parameters. The samples obtained from industrial and agricultural areas for identifying water tables at higher risk and display region...
