Description:
Purpose:
This data set contains spatial and grain-size information for 13 of the 24 vibracores collected by the U.S. Geological Survey during a 2007 cruise within Apalachicola Bay, Florida. These data are available in shapefile, CSV, and XLS format.
Abstract:
In 2007, the U.S. Geological Survey collected 24 vibracores within Apalachicola Bay, Florida. The vibracores were collected using a Rossfelder electric percussive (P-3) vibracore system during a cruise on the R/V Gilbert. Selection of the core sites was based on a geophysical survey that was conducted during 2005 and 2006 in collaboration with the National Oceanic and Atmospheric Administrations (NOAA) Coastal Services Center (CSC) and the Apalachicola Bay National Estuarine Research Reserve. Available data include the vibracore data logs and photographs, select seismic-reflection profiles (from the geophysical survey), and core-derived data including: grain size analyses, radiocarbon ages, microfossil counts, and sedimentological interpretations. The long-term goal of this study is to provide maps, data, and assistance to the Apalachicola Bay National Estuarine Research Reserve in their effort to monitor and understand the geology and ecology of Apalachicola Bay Estuary. These data will inform coastal managers charged with resource preservation.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
All attributes were checked to ensure that the data translation from spreadsheet to shapefile and back was correct.
Logical_Consistency_Report:
Any spurious data points were removed during creation of the spreadsheet file. These data are related to centimeter-scale subsamples within vibracores collected by USGS in 2007. The whole-core determinations are located in a separate file.
Completeness_Report:
Navigation from ship GPS was used to generate this shapefile. All vibracores were collected from the R/V Gilbert using a Rossfelder vibracore. One vibracore was collected at each of the 23 predetermined locations, with the exception of site 18. Two cores were collected here because the first core (App07-18A) was recovered without a core catcher on the end, and several centimeters of the sample were lost. A second core was taken (App07-18B) at site 18, and both cores were processed and preserved. Of the 24 vibracores collected, 13 were selected for grain-size analysis. This file contains sample data from within these 13 selected vibracores. All grain-size analyses were completed in the Sediment Laboratory as the U.S. Geological Survey Woods Hole Science Center (WHSC). All the grain-size results for the coarse fraction in all the cores was derived from sieving the >62 micron (-5 phi to 4 phi) fraction. The fine-fraction (< 62 microns; 5 phi to 11 phi) was analysed by coulter counter for all cores with the exception of core 19 which was fine sampled using a settling tube because the fine fraction was overwhelming the coulter counter in this sample. This resulted in a difference in reporting statistics for core 19, which is evident in the attribute table (values of 999). Core 19 is lacking percent statistics for phi sizes 5 through 11. Refer to the percent silt (for cumulative percent of 5 phi to 8 phi) and percent clay (for cumulative percent of 9 phi to 11 phi) statistics instead. A null value of 999 is reported for core 19 in the following fields: Median, mean, stdev, skewness, kurtosis, phi_5, phi_6, phi_7, phi_8, phi_9, phi_10, and phi_11.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The vibracore location for these data were recorded from the ship's Differential Global Positioning System (DGPS); they are accurate to +/- 1 to 2 meters, horizontally. Additionally, the ship was anchored from the stern and bow during vibracore collection, and this configuration could create extra horizontal uncertainty. Core locations are assumed to be accurate within +/- 20 meters.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The water depth value in the attribute table is taken from the 25-m Apalachicola Bathymetric grid included in this report. Please see the metadata file for apbaybath25m for more detailed vertical accuracy information.

Process_Description:
Sediment samples within select vibracores were collected at depth intervals for grain-size analysis. In total 117 grain-size analyses were conducted on samples from 13 of the 24 vibracores. Samples, approximately 2x2x2 cm in size, were collected away from the edges of the cores to minimize core disturbance and stored in labeled plastic bags. Grain-size analyses were completed in the Sediment Laboratory as the U.S. Geological Survey Woods Hole Science Center (WHSC). Grain-size results for the coarse fraction in all the cores was derived from sieving the >62 micron fraction. The fine-fraction (< 62 microns) was analysed by coulter counter, and in one case (core App07-19) a settling tube. Sample information was recorded in 44 fields in a spreadsheet (Microsoft Office Excel 2003). Information recorded includes: core location, core id, sample id, top of sample, base of sample, bulk weight, percent of sample in each 1-phi size, percent sand, sediment classification, analyst, skewness, kurtosis, and other sediment-related statistics (Poppe and others, 2005).

Twenty-four vibracores were collected within Apalachicola Bay, Florida during May 2007. Vibracore sites were selected based on the identification of target areas. These target areas were chosen from the analysis of geophysical data collected during 2005 and 2006 in collaboration with the National Oceanic and Atmospheric Administrations (NOAA) Coastal Services Center (CSC) and the Apalachicola Bay National Estuarine Research Reserve. The vibracores were collected using a Rossfelder percussive (P-3) electric vibracore system. The cores were collected in a 7.62 cm (3 in) diameter by 6.10 m (20 ft) long aluminum tube with a copper core catcher riveted to the bottom. The vibracoring rig was mounted, depolyed, and recovered on the port side of the R/V Gilbert. The ship was anchored from the bow and stern to maintain ship position as a hydraulic crane deployed and recovered the coring rig. Following recovery, the bottom of the core was capped with a plastic cap, water was drained from the top of the core barrel by drilling a hole in the aluminum tube immediately above the sediment/water interface, and the pipe was cut at the sediment/water interface. Each core was cut into one-meter sections (measuring down from the sediment/water interface) on the boat deck, the ends were capped, each section labeled, and stored on deck for transport. Core sections for all 24 vibracores were transported to the U.S. Geological Survey Florida Integrated Science Center (FISC) where the 1-meter core sections were split in half (lengthwise), described, and photographed in the FISC core laboratory. One half of each core section was preserved and archived in a clear plastic sleeve with the ends taped shut to minimize moisture loss. The other half, the working half, of the core was used for visual descriptions, photographs, and eventually sub-sampling. Visual core descriptions were recorded on field sheets that contained information regarding: cruise, core number, describer, general station location, lithologic units, sedimentary structures, biota, and a depiction of the stratigraphic column. The cores were photographed by aligning all sections of a vibracore abreast with depth indicators located between sections. After photographing, all core sections were wrapped in plastic sleeves with the ends taped shut to minimize moisture loss, and stored in labeled cardboard boxes in the FISC core repository.

Process_Description:
Vibracore location and grain-size information was exported from the spreadsheet (Microsoft Office Excel 2003) as a comma-separated value (CSV) file and imported to ArcCatalog (version 9.3) by right-clicking on the CSV file and selecting 'create feature class --> from XY table'. Parameters for the import are: X Field - longitude; Y Field - latitude; Z Field - water depth. This process created an ESRI point Z shapefile where each subsample from a vibracore is a unique record with sample specific attributes. The original depth value (Z) was recorded in the spreadsheet from the ship's fathometer (not tide corrected). This value was replaced in ArcGIS using XTools Pro (version 5.2) for ArcGIS desktop --> Table Operations -->Add X,Y,Z coordinates. Only the Z coordinate was added using z-values from the tide-corrected (MLLW) basemap: apbaybath25m. This created a vertical measue of water depth at each core location in meters below MLLW.
