Archive of Chirp Subbottom Profile Data Collected in 2022 From Breton Island, Louisiana
As part of the Breton Island Post Construction Monitoring project, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted a nearshore geophysical survey in August of 2022 to map the borrow site created during the Breton Island, Louisiana restoration effort that began in December 2020. The objective of the project is to provide baseline information of the physical structure of the dredge pit in order to monitor morphologic evolution over time. Collecting geophysical data can help researchers to identify relationships between the geologic history of the island, its present-day morphology, and sediment distribution. High-resolution geophysical data collected along this barrier island can further the analyses and geomorphological interpretations of this and other coastal systems, improving researchers understanding of coastal response and evolution.
This data release serves as an archive of subbottom profile and navigation data collected August 5, 2022, offshore of Breton Island, LA, during USGS Field Activity Number 2022-328-FA. Data products, including chirp subbottom profile data and images, survey trackline maps, location data with formal Federal Geographic Data Committee (FGDC) metadata, and field logs are provided
