USGS storm-tide sensor bolted to a cement jetty on the Atlantic Ocean coast at Fire Island, New York. USGS scientists deployed over 50 sensors along the coast of Maine, New Hampshire, Massachusetts, Rhode Island, Connecticut, New York, New Jersey and Delaware to study a Nor'easter that affected the Northeast in March of 2018.

USGS technicians preparing for a streamflow measurement by lowering an acoustic Doppler current profiler from a cable way on the American River near Fair Oaks, California. 

This digital elevation model was created using structure from motion software mounted to an Unmanned Aerial System (UAS) to analyze bridge scour. Studies using UAS have included stream temperature analyses, bird and mammal surveys, coastal change mapping, sandbar habitat surveys, fluvial erosion rates, microclimate mapping, air quality analysis, plant stress as

Hydrologic Technician Jacob Wikle snapped this photo of the Vermejo River while he was out searching for groundwater wells near the ghost town of Dawson, New Mexico, as part of the statewide groundwater monitoring network.

Is this cemetery haunted? Probably not, but there could be tiny things moving beyond the grave. The USGS sampled groundwater downhill of Mt. Hope Cemetery in Lansing, Michigan, to find out if materials associated with decomposition and burial processes could affect groundwater quality near a cemetery.

This small unmanned aerial system with digital camera has been used to create digital elevation models to answer questions about erosion, bridge scour, and other hydraulics analyses.
