Sample sites varied between high marshes, low salt marshes, and sand flats. This report serves as an archive for the sedimentological and geochemical data derived from the marsh cores and select surface data from the corresponding marsh core sites collected in August, 2015 (15BIM09). Downloadable data are available and include Excel spreadsheets, JPEG files, and formal Federal Geographic Data Committee metadata. For further information regarding data collection and/or processing methods refer to USGS OFR Ellis and others 2017–1165 (https://doi.org/10.3133/OFR20171165), and Data Series Ellis and others 2017–1046 (https://doi.org/10.3133/DS20171046). Purpose: Dissemination of processed sediment data from sediment core intervals collected from ten sites on Dauphin Island, Alabama, in August 2015 (USGS FAN 2015-322-FA). Supplemental_Information: To ensure that USGS-St. Petersburg data management protocols were followed, this survey was assigned the following USGS field activity number (FAN): 2015-322-FA (Project ID 15BIM09), additional survey and data details are available at https://cmgds.marine.usgs.gov/fan_info.php?fan=2015-322-FA. In August, 2015, USGS scientists collected eleven sediment push cores from ten unique sites on Dauphin Island, a barrier island in the northern Gulf of Mexico. The sample locations field setup consisted of a rover Global Positioning System (GPS) unit used to collect data at each sample site, and two base stations. Base stations were established approximately 11 kilometers (km) apart to ensure coverage throughout the island. During field sampling, shear vane measurements were collected at each site along with water parameter measurements, when possible, which are included in this report.

Differential Global Positioning System (DGPS) coordinates were obtained using post-processing software packages (National Geodetic Survey On-Line Positioning User Service, OPUS, and Novatel Waypoint Product Group GrafNav). Replicate analyses of loss on ignition are reported for quality assurance. The grain size data represent the sample averages for a subset of the statistical parameters calculated by GRADISTAT. The number of runs included in the averaged results are reported, and the standard deviation of the averaged results are reported for most parameters. The alpha spectroscopic radioisotope activities reported include the counting error for all samples. Logical_Consistency_Report: The 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 are highlighted in yellow and were not included in final averaged results. No formal logical accuracy tests were conducted on the remaining datasets. Completeness_Report: The data release doi:10.5066/F7VM49J0 associated with this metadata includes the geographic site location, water quality parameters, sediment physical properties, grain size statistics, shear vane measurements, and sediment radiochemistry activities for eleven cores collected at ten sties on Dauphin Island, Alabama, in August, 2015. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: All static GPS base station sessions were processed through the On-Line Positioning User Service (OPUS) maintained by the National Geodetic Survey (NGS). The OPUS base-station solutions were entered into a spreadsheet to compute a final, time-weighted positional coordinate (latitude, longitude, and ellipsoid height) for each base station. Base-station positional error was calculated as the absolute value of the final position minus the session position value. The maximum horizontal error of the base station coordinates used for post-processing the sample locations was 0.00005 seconds latitude and 0.00015 seconds longitude. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: All static GPS base station sessions were processed through OPUS. The OPUS base-station solutions were entered into a spreadsheet to compute a final, time-weighted positional coordinate (latitude, longitude, and ellipsoid height) for each base station. Base-station positional error for each GPS session was calculated as the absolute value of the final position minus the session position value. For this survey, the maximum standard deviation of the base station ellipsoid height was 0.009 m and the maximum vertical error for the base station was +/- 0.016 m. The time-weighted average positions were compared with the NPS network control numbers for each base station; the time-weighted elevations for each base station occupation were within 2 standard deviations of the NPS control elevations. The NPS control coordinates were used for subsequent post processing. Lineage: Process_Step: Process_Description: At ten sites on Dauphin Island, marsh push cores were collected with 11.4-cm diameter polycarbonate barrels. Upon retrieval, the cores were visually inspected for an undisturbed surface. A replicate core was collected at site DA31. Core lengths ranged between 24 and 59 cm. The cores were transported upright to the SPCMSC laboratory for sectioning. At select sites, Russian peat augers were collected and occasionally sampled in the field for micropaleontology. The data associated with those peat cores will be made available at another time. Water quality properties were measured with an YSI Professional Plus multi-sensor meter in the standing water at each site where there was standing water. Shear vane measurements were recorded within a couple of meters of each marsh push core site using an AMS field shear vane (https://www.ams-samplers.com/pdfs/ams-Field-Vane-Shear-Tester-Kit.pdf). At each site, four measurements were collected, one in the center of each quadrant of a 1 square meter grid, in order to account for variation in vegetation, sediment, and users. Site coordinates were recorded using a GPS antenna in the NAD83 datum with base station set up. Site location information including latitude, longitude, elevation, environment type, vegetation, and YSI measurements are reported in Excel spreadsheets. Comma-separated values data files containing the tabular data in plain text are included in the download files.

Water content, porosity, and dry bulk density were calculated by determining water mass lost during drying. Known volumes of each wet subsample, usually 30-60 milliliters (mL), were packed into a graduated syringe with 0.5 cubic centimeter (cm^3) resolution. The wet sediment sample was then extruded into a pre-weighed aluminum tray, and the weight was recorded. The wet sediment sample and tray were placed in a drying oven for 48 hours at 60 °C. Water content (?) was determined as the mass of water (lost when dried) relative to the initial wet sediment mass. Porosity (?) was estimated from the equation ? = ? / [?+(1-?)/?s] where ?s is grain density assumed to be 2.5 grams per cubic centimeter (g/cm^3). Salt-mass contributions were removed based on the salinity measured at the time of sample collection. If salinity was not measured in the field, pore water salinity was estimated to be 25. Dry bulk density (g/cm^3) was determined by the ratio of dry sediment to the known volume of sediment packed into the syringe. Water content, porosity and dry bulk density are reported in the Excel spreadsheet. A comma-separated values data file containing the tabular data in plain text is included in the download file.

The dry sediment sample from the previous process was homogenized with a porcelain mortar and pestle. Approximately 2.5 or 5 grams (g) of the dry sediment was placed into a pre-weighed porcelain crucible. The mass of the dried sediment was recorded with a precision of 0.01 g on an analytical balance. The sample was then placed inside a laboratory muffle furnace with stabilizing temperature control. The furnace was heated to 110 °C for a minimum of 6 hours to remove hygroscopic water adsorbed onto the sediment particles. The furnace temperature was then lowered to 60 °C, at which point the sediments could be reweighed safely. The dried sediment was returned to the muffle furnace. The furnace was heated to 550 °C over a period of 30 minutes and kept at 550 °C for 6 hours. The furnace temperature was then lowered to 60 °C, at which point the sediments could be reweighed safely. The mass lost during the 6-hour baking period relative to the 110 °C-dried mass is used as a metric of OM content (modified from Dean, 1974). Approximately 19 percent of the field samples were run in duplicate for LOI to assess precision. Data are reported as a ratio of mass (g) of organic matter to mass (g) of dry sediment (post-110 °C drying). Replicate analyses of loss on ignition are reported for quality assurance in the Excel spreadsheet. A comma-separated values data file containing the tabular data in plain text is included in the download file.

The H2O2 was then evaporated slowly on a hot plate, and the sediment was washed and centrifuged twice with deionized water. To prevent damage to the Coulter LS 13 320, particles greater than 1 millimeter (mm) in diameter were removed with a 1 mm sieve. The samples were washed through the sieve with a five percent solution of sodium hexametaphosphate with filtered municipal water to act as a deflocculant. The sediment slurry was sonicated with a wand sonicator for 30–60 seconds before being introduced into the particle size analyzer. Two subsamples from each sample were processed with a minimum of four runs apiece. The data for each sample was exported as relative volumes for 92 size-classification channels, or bins, which correspond with the size-classification boundaries for American Society for Testing and Materials (ASTM) E11 standard specification for wire cloth and sieves for testing purposes.

(Krumbein, 1934) using the Folk and Ward (1957) method. GRADISTAT also calculates the fraction of sediment from each sample by size category (for example, clay, coarse silt, fine sand) based on Friedman and Saunders (1978), a modified Wentworth (1922) size scale. A macro function in Microsoft Excel, developed by the USGS SPCMSC, was applied to the data to calculate the 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 results for all samples, including the number of averaged runs and the standard deviation of the averaged results were summarized in an of Excel workbook with each core on its own tab. A comma-separated values data file containing the tabular data in plain text is included in the download file.

In the laboratory, approximately 3.0 g of dried and homogenized sediment was spiked with 0.5 mL of polonium-209 (209Po), with an activity of 12 disintegrations per minute per milliliter (dpm/mL). The sediment was then leached by the addition and subsequent evaporation to near dryness with a combination of concentrated nitric acid, hydrochloric acid, and 30 percent H2O2. Polonium-210 (210Po) and 209Po were electroplated onto silver planchets and counted twice, in two different chambers, for 24 hours on an ORTEC Alpha Ensemble multi-chamber spectrometer. Count rate efficiency was determined for 209Po and applied to the 210Po counts. The total 210Pb was assumed to be in secular equilibrium with its granddaughter, 210Po in the down-core sediment. The radioisotopic activities reported in the Excel spreadsheet include the counting error for all samples.
