Snapshot, or first frame of from a 17-minute video shot on June 20, 2017, in Madeira Beach, Florida.

“Variance” image produced from video shot at Madeira Beach, Florida, on June 20, 2017. The more the light intensity changes at a given spot, or “pixel,” during the video, the brighter the value assigned to that pixel. Motion tends to produce changes in light intensity. Note bright bands parallel to shore where waves were breaking.

Photograph taken June 7, 2016, one day after Tropical Storm Colin, on Sunset Beach in the town of St. Pete Beach, Florida. Storm waves eroded the beach and dune, producing a cliff-like feature called a beach scarp.

Scientists from the USGS St Petersburg Coastal and Marine Science Center (SPCMSC) capture the smooth water of the tidal creek reflecting a pastel sky and soft clouds while heading out for field work at early dawn.

Scientists deploy a Chirp seismic instrument from the beach. Seismic data provide view of sub-seafloor geology, which records depositional and erosional events and reveals geologic controls on sediment supply.

Samples are recovered from the sediment trap once every 9-12 months. Cruises to recover and redeploy the mooring take place on the UNOLS vessel, R/V Pelican, operated by LUMCON, in Cocodrie, Louisianna.

A net sedimentation tile (NST) is used by scientists to measure surface sediment deposition in wetlands over short time scales. Scientists installed several NSTs on the surface of the marsh to measure sediment deposition. The samples are retrieved and measured in the lab to identify short-term sediment deposition rates on the marsh surface.

The USGS strives to put coastal change data and information at the fingertips of users such as planners and emergency managers. The explicit goal is to enable users to integrate and apply USGS data and tools to address their specific needs. Online resources such as the Coastal Change Hazards (CCH) portal are designed with applied use of data in mind.

At Fire Island, estuarine, wetland, coastal, and oceanic processes interact, affecting natural and human communities. The CMHRP has been conducting scientific investigations at Fire Island in order to protect coastal infrastructure.

USGS research oceanographers Jenna Brown and Joe Long installed this video camera atop the Shoreline Island Resort hotel in Madeira Beach, Florida. Starting in February 2017, the camera has recorded video for 17 minutes every hour during daylight hours.
