Archive of Chirp Subbottom Profile and Single-Beam Bathymetry Data Collected in 2021 From Santa Rosa Island, Florida

As part of the Coastal Resource Evaluation for Management Applications (CREMA) Project, 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 Pensacola Beach, Florida (FL) in June of 2021. 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 peninsula, its present-day morphology, and sediment distribution. High-resolution geophysical data collected along this peninsula 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, single-beam bathymetry, and navigation data collected June 2-9, 2021, offshore of Pensacola Beach, FL, during USGS Field Activity Number 2021-322-FA. Data products, including chirp subbottom profile data and images, processed elevation point data (XYZ), survey trackline maps, location data with formal Federal Geographic Data Committee (FGDC) metadata, and field logs are provided. Coastal multibeam bathymetry data were also collected for this project (during USGS Field Activity Number 2019-326-FA) and are provided in another data release (Farmer and others, 2020).
