Archive of Chirp Subbottom Profile Data Collected in June 2018 From Fire Island, New York

March 5, 2019

Researchers from the U.S. Geological Survey (USGS) conducted a long-term, coastal morphologic-change study at Fire Island, New York, prior to and after Hurricane Sandy impacted the area in October 2012. The Fire Island Coastal System Change project objectives include understanding the morphologic evolution of the barrier island system on a variety of time scales (months to centuries) and resolving storm-related impacts, post-storm beach response, and recovery. In June 2018, scientists from the USGS St. Petersburg Coastal and Marine Science Center conducted geophysical surveys on Fire Island to characterize and quantify spatial variability in the subaerial geology with the goal of subsequently integrating onshore geology with other shoreface datasets also collected under the Disaster Relief Appropriations Act of 2013, using the U.S. Department of the Interior Hurricane Sandy supplemental funding.

This data release serves as an archive of high-resolution subbottom profiles and differential global positioning system (DGPS) navigation data collected from beach and nearshore environments on Fire Island, June 2-16, 2018 (USGS Field Activity Number 2018-322-FA). USGS scientists created a purpose-built, towed sled system to mount the chirp profiler (just below the water's surface) and enable launching and recovery from the foreshore. The seismic sled was also configured to help ensure the quality of data collected in exceedingly shallow water depths, such as those observed near the shoreline and surf zone. For additional information regarding data acquisition and processing methods, refer to the metadata.
