# Archive of Chirp Subbottom Profile Data Collected in 2015 From Dauphin Island, Alabama

October 18, 2022
View Data Release

As part of the Alabama Barrier Island Restoration Feasibility Study, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted a nearshore geophysical survey to map the shoreface and determine Holocene stratigraphy near Dauphin Island, Alabama (AL) in September of 2015. The objective of the project is to investigate nearshore geologic controls on surface morphology. 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 September 16-23, 2015, offshore of Dauphin Island, AL, during USGS Field Activity Number 2015-330-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.
