Climate Variability

Regional groundwater availability studies enable information about groundwater to be integrated and consistent, so that this resource can be analyzed and understood on an aquifer–wide scale. These studies provide decision–makers with a better understanding of the status and trends in the Nation's groundwater availability.

The USGS is undertaking a 3-year study of water availability and use to investigate competing societal and ecological needs in Southeastern Atlantic Coastal Basins of the Carolinas. This study will compile existing information, add new scientific data and interpretation, and develop tools to help resource managers and stakeholders address current and future water-use challenges.

For the past 50 years, the USGS has been conducting research in the San Francisco Bay and Delta, California and beyond. This research would not have been possible without the Research Vessel (R/V) Polaris. Many scientists who have been fortunate to work on the Polaris have come and gone, but the Polaris sailed from the South San Francisco Bay continuously from 1968 until her retirement in 2015.

Methyl halide contaminants are oxidized in a reaction chamber containing a methylotrophic bacterium through direct oxidation of the methyl halide contaminant. (Full details provided by the U.S. Patent and Trademark Office website.)
