USGS hydrologists deploy fiber-optic distributed temperature sensing equipment in Ashumet Pond, Mashpee, Massachusetts. Fiber-optic distributed temperature sensing is an emerging technology that has promise for characterizing estuary-aquifer interaction. The technology evaluation was conducted by the USGS Office of Groundwater Branch of Geophysics in 2007.

Evaluating Geophysical Equipment & Methods
USGS hydrologists monitor data collection during a geophysical survey using the horizontal-to-vertical ambient-noise seismic method. This method can be used to estimate unconsolidated sediment thickness and map the bedrock surface as part of groundwater investigations.

Public Wells
Example of a pump and plumbing configuration used by public water systems. About 105 million peopleor more than one-third of the Nation's populationreceive their drinking water from one of the 140,000 public water systems across the United States that rely on groundwater pumped from public wells.

Giant Caribbean Anemone (Condylactis gigantea)
Condylactis gigantea fluourescing on rocks. The anemones are in a tank illuminated by ultraviolet (black) light. The anemones absorb the invisible ultraviolet light and reflect it back as visible bright green light.
