R/V Sallenger and seismic sled used for sub-bottom surveying

A team of USGS scientists work off the R/V Sallenger in Rockaway Beach, New York. One team member stands on a floating sled that enables sub‐bottom surveying in shallow water, nearshore, and shore‐face environments. The sled is equipped with an EdgeTech SB‐512i CHIRP system and single‐beam sonar. This equipment is used to collect seismic sub‐bottom profiles and single‐beam bathymetry in order to provide comprehensive baseline data of the nearshore environment for future monitoring.
