Delaware River Basin Focus Area Study
As one of several National Focus Area Studies within the USGS National Water Census (NWC), the USGS completed a 3-year study of water availability and use in the Delaware River Basin.
The Story of the USGS Research Vessel (R/V) Polaris
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...
