This photo shows a snow plow and road salt application truck that is used to clear snow and ice from roadways for improving traffic and pedestrian safety. The use of salt to deice pavement can be harmful to aquatic life in urban streams. The USGS is involved in studies that focus on the influence of winter runoff on aquatic ecosystems.

Sunset Tripods on Deck
As part of an investigation of the mechanisms of coastal change in the Carolinas, instrumented tripods were deployed on Diamond Shoals near Cape Hatteras, NC.

Checking Tripod Release Mechanism
As part of an investigation of the mechanisms of coastal change in the Carolinas, instrumented tripods were deployed on Diamond Shoals near Cape Hatteras, NC. These tripods recorded data quantifying the currents, waves, turbidity, temperature and salinity at several levels near the seafloor between January and April 2009.

Lidar shaded relief map of the Hayward Fault and UC Berkeley stadium
Lidar shaded relief map of the Hayward Fault and UC Berkeley stadiumA filtered vertical laser image, taken using a technique called light detection and ranging (LIDAR), of part of the Hayward Fault (red lines) in the City of Berkeley. The fault passes through the University of California Berkeley football stadium (left), and past earthquake movements have significantly offset Hamilton Gulch (center).

Rhode Island Seafloor
This photograph is of the seafloor on the Rhode Island coast and shows a skate on a fine-grained, likely silty or muddy seafloor. This photograph was collected to support research and management activities (e.g., wind farms and fisheries) along the Rhode Island inner continental shelf.
