This study investigated the past evolution of the CFGC from field sites at Anclote Keys, Caladesi and Honeymoon Islands, and Fort DeSoto to quantify changes that occurred along these barrier systems prior to the 20th century. Purpose: This data release serves as an archive of sedimentologic data from vibracores collected from back-barrier environments at Dutchman Key (DK), Anclote Key (AK), Caladesi Island (CI), Honeymoon Island (HI), Cabbage Key (CK), St. Jean Key (SJK), and Mullet Key (MK) study sites on February 19 and May 11-13, 2021 (USGS Field Activity Number 2021-308-FA). GPR data collected during the same survey are available as a separate data release (Forde and others, 2023). Sedimentologic data from these cores, including descriptive core logs and grain-size data, are provided to characterize and date shallow subsurface stratigraphic units including beach, dune, and washover deposits. Samples selected for Optically Stimulated Luminescence (OSL) dating were analyzed at the USGS Luminescence Dating Laboratory (Denver, Colorado); those results are available as a separate data release. These data were targeted according to the methods outlined by Ciarletta and others (2023), with sediment cores positioned to investigate interpretations of barrier-island evolution from surface morphology. Acquisition of sediment cores and analyses of core lithology and grain size follow the methods of Buster and others (2018), with modifications for high-resolution photography after Ciarletta and others (2023). Supplemental_Information: Data were collected during USGS FAN 2021-308-FA. Additional survey and data details are available on the U.S. Geological Survey Coastal and Marine Geoscience Data System (CMGDS) at, https://cmgds.marine.usgs.gov/fan_info.php?fan=2021-308-FA.

Due to the assumption of grain sphericity of the Fraunhofer optical model used by the Coulter LS13 320 particle-size analyzer (PSA) for grain-size analysis, angular particles are measured by their longest axis (Beckman Coulter, 2011). When enough thin, angular material is present, the LS13 320 output files often report a percentage of the grain size distribution within the 1-2-millimeter (mm) fraction, despite all samples being sieved at 1 mm before analysis. The grain-size data represent the sample averages for a subset of the statistical parameters calculated by GRADISTAT (Blott and Pye, 2001). The number of runs included in the averaged results are reported, and the standard deviation of the averaged results are reported for most parameters. A secondary data review determined that all grain-size data reported met the laboratory’s quality control requirements. Beckman Coulter control standard G15 (15 microns [µm]) was analyzed on the Coulter LS13 320 particle-size analyzer before all sediment samples were analyzed and Beckman Coulter control standard GB500 (500 µm) was analyzed approximately every 3 days to validate instrument performance (Beckman Coulter, 2011). Logical_Consistency_Report: Position and elevation data at each core site were recorded with a Spectra Precision SP80 DGPS receiver and Global Navigation Satellite System (GNSS) antenna. Grain-size sample runs in the GRADISTAT output files for which the mean Folk and Ward (1957) grain-size varied from the set average by more than 1.5 standard deviations were not included in final averaged results. Completeness_Report: Dataset is considered complete for the information presented, as described in the abstract. This data release includes the geographic locations, site elevations, core descriptions, core photos, and grain-size data (127 samples) from 11 vibracores collected from Dutchman Key, Anclote Key, Caladesi Island, Honeymoon Island, Cabbage Key, St. Jean Key, and Mullet Key study sites, Pinellas County, FL on February 19 and May 11-13, 2021 (USGS Field Activity Number 2021-308-FA). Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Position and elevation associated with each core site was determined by either (a) DGPS RTK corrections during data collection or (b) processing the raw position data during data collection through OPUS (core site SJK1). For RTK occupations, the reported horizontal accuracy ranged from 0.008 meters (m) to 0.018 m; at SJK1, the OPUS-derived estimated horizontal accuracy was 0.007 m. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Position and elevation associated with each core site was determined by either (a) DGPS RTK corrections during data collection or (b) processing the raw position data during data collection through OPUS (core site SJK1). For RTK occupations, the reported vertical accuracy ranged from 0.011 to 0.030 m and the VDatum-reported transformation uncertainty was 0.076 m; at SJK1, the OPUS-derive estimated vertical accuracy was 0.038 m. Lineage: Process_Step: Process_Description: Vibracore acquisition- Vibracores were collected using an 8-horsepower Briggs and Stratton motor connected via an 8.5-meter-long (27.9-foot-long) shaft to a Dreyer 2 1/8-inch (5.4 centimeter [cm]) concrete vibrator head. The vibrator was attached to a 7.6-cm (3-inch) diameter aluminum core barrel using a clamp, and the core barrel was vibrated into the subsurface until refusal. Measurements were taken on the inside and outside of the core barrel prior to extraction to determine the amount of compaction, which is the difference between the recovered core length and the total depth the core barrel penetrated below the sediment surface. After extraction, each core was capped, sealed, and labeled with the core number and orientation. All cores were transported to the SPCMSC core laboratory for processing and analysis. Position and elevation data at each vibracore site were recorded using a Spectra Precision SP80 DGPS receiver and GNSS antenna receiving RTK corrections from the Florida Permanent Reference Network (FPRN) real-time network. RTK x,y positions were acquired in the Florida State Plane coordinate system and transformed to the North American Datum of 1983 (NAD83) Universal Transverse Mercator Zone 17 North (UTM 17N) coordinate system using NGS VDatum software. RTK elevations were acquired as Florida State Plane ellipsoid heights and transformed to North American Vertical Datum 1988 (NAVD88) orthometric elevations, derived using the GEOID18 (G18) geodetic model. For SJK1, the raw position data were processed through OPUS. The OPUS-derived x,y coordinates were reported in NAD83, UTM 17N, and the OPUS-derived elevations were reported as NAVD88 G18 orthometric elevations. Core information was compiled into a comma-separated values file (.csv) and Microsoft Excel Worksheet (.xlsx) for inclusion in this data release. The 2021-308-FA_CoreSites.csv table was converted to a point shapefile (.shp) using the 'Table To Point Feature Class' geoprocessing tool in ArcGIS Pro to produce a geographic representation of the core sites. A non-proprietary version of the shapefile was created by converting the shapefile to a keyhole markup language (.kml) file in Google Earth Pro. These geospatial files can be found in 2021-308-FA_CoreSites.zip.

Because samples were collected for OSL dating, care was taken not to expose the sediment to light. Core splitting and sampling was conducted in the dark with only a photographer's red lamp and the sample half of each core was wrapped in lightproof material for storage prior to subsampling. The archive half of each core was photographed in approximately 20- to 25-cm overlapping segments with a Nikon D80 digital camera with a 70 mm zoom lens using consistent (manually programmed) settings with autofocus from a fixed height. The raw images were white-balanced using GNU Image Manipulation Program (GIMP) software, cropped to the same extent (to remove areas outside of the core barrel), and "stitched" together using The Panorama Factory software, providing seamless high-resolution whole-core images. Textural descriptions for the core logs are based on macroscopic observations. Sediment color is based on the Munsell soil color system (https://munsell.com/color-products/color-communications-products/environmental-color-communication/munsell-soil-color-charts/). Descriptive core logs were compiled using Rockware LogPlot 8 software, edited in Adobe Illustrator, and exported as Joint Photographic Experts Group (JPEG) images. Core photo and core log images are included in the 2021-308-FA_CorePhotos.zip and 2021-308-FA_CoreLogs.zip files of this data release. Grain-size and age-control samples consisted of 2-cm sections sampled at varying intervals down-core depending on the number and thickness of the observed sedimentologic units. Samples collected for OSL dating were placed in lightproof film canisters, labeled, and sent to the USGS Luminescence Dating Laboratory (Denver, Colorado) for analysis.

The LS13 320 uses laser diffraction to measure the size distribution of sediments from 0.4 µm to 2 mm, encompassing clay to very coarse-grained sand. To prevent large shell fragments from damaging the instrument, particles greater than 1 mm in diameter (coarse sand) were separated from all samples prior to analysis using a number 18 (1 mm) U.S. standard sieve, which meets the American Society for Testing and Materials (ASTM) E11 standard specifications for determining particle size using woven-wire test sieves. Two subsamples from each sample were processed through the instrument a minimum of four runs each. Once introduced into the LS13 320, the sediment in the sample well was sonicated with a sonicator wand for 30 seconds (s) to separate any aggregates before starting the first run for both subsamples. The LS13 320 measures the particle-size distribution of each sample by passing sediment suspended in solution between two narrow panes of glass in front of a laser. Light is scattered by the particles into characteristic refraction patterns measured by an array of photodetectors as intensity per unit area and recorded as relative volume for 92 size-related channels (bins).

The raw (run) LS13 320 output files for all samples were compiled by GRADISTAT during import; those raw data are included in this data release for advanced users in the file 2021-308-FA_GrainSizeData.zip. GRADISTAT also reports the descriptive sediment texture after Folk (1954) and calculates the fraction of sediment from each sample by size category (for example, clay, coarse silt, fine sand) based on a modified Wentworth (1922) size scale. A macro function in Microsoft Excel, developed by the USGS SPCMSC, was applied to the data to calculate average and standard deviation for each sample set (8 runs per sample), and highlight runs that varied from the set average by more than ±1.5 standard deviations. Excessive deviations from the mean are likely the result of equipment error or extraneous organic material in the sample and are not considered representative of the sample. The highlighted runs were removed from the results and the sample average was recalculated using the remaining runs. The averaged (summary) results for all samples are included as a tab in a Microsoft Excel workbook (2021-308-FA_GrainSizeStats.xlsx) and as a comma-separated values (2021-308-FA_GrainSize_SumStats.csv) data file. The raw LS13 320 run data are also included as tabs (separated by core) in an Excel workbook (2021-308-FA_GrainSize_RunData.xlsx) and as a comma-separated values (2021-308-FA_GrainSize_RunData.csv) data file.

The sediment was passed through a stack of sieves with progressively smaller openings using the assistance of a mechanical sieve shaker to determine grain-size distribution. U.S. standard sieves numbers 230 (63 µm), 120 (125 µm), 60 (250 µm), 35 (500 µm), 18 (1 mm), and 10 (2 mm) were used, which meet the ASTM E11 standard specifications for determining particle size using woven-wire test sieves. All dry sieve data was reported as a percent fraction of the total bulk dry weight of each sample subset.

The images were grouped by image type (core logs and photographs) into separate folders: 2021-308-FA_CoreLogs (11 images) and 2021-308-FA_CorePhotos (17 images). All information in the scripts were the same among all images, aside from the EXIF:ImageDescription, EXIF:DateTimeOriginal, EXIF:GPSLatitude and EXIF:GPSLongtitude information, as that information varies for each core. A separate script containing that header information was run on each image individually to populate those headers (see the third script). Image header information was also populated for 2021-308-FA_GrainSizeDistributions.jpg in 2021-308-FA_GrainSizeData.zip. However, since this image details grain-size distributions for all collected cores, the third script was not used, along with removing EXIF:GPSMapDatum and EXIF:GPSAreaInformation in the second script.
