Description:
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 Administration’s (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.
Purpose:
This data set contains spatial and radiocarbon age information for 10 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.

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, 10 were selected for radiocarbon age date sampling. This file contains sample data from within these 10 selected vibracores
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.

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 Administration’s (NOAA) Coastal Services Center (CSC) and the Apalachicola Bay National Estuarine Research Reserve. The vibracores were collected using a Rossfelder electric percussive (P-3) 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_Step:
Process_Description:
Wood fragments and shells were collected within select vibracores for radiocarbon age analysis. In total 34 radiocarbon ages were produced from wood fragments and shells in 10 of the 24 vibracores. Wood and shell samples were converted to graphite targets at a U.S. Geological Survey laboratory in Reston, VA, and the AMS 14C ages were determined on these targets at the Center for Accelerator Mass Spectrometry, Lawrence Livermore National Laboratory in Livermore, CA. The age results were recorded in a spreadsheet (Microsoft Office Excel 2003) including: core location, core id, top of sample, base of sample, material dated, 14C age, and age error. All dates were 14C dates (in years before 1950) and had no corrections applied to them.

Process_Description:
Vibracore location and radiocarbon age 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.

The final radiocarbon shapefile was exported to Microsoft Excel format (XLS) and Comma-Separated Value (CSV) format using ArcMap (version 9.3) and XTools Pro (version 5.2) for ArcGIS desktop. This final export to CSV and XLS format was done to include the ESRI generated fields in all formats of the data, and to correct the Z-value to MLLW in all files.

Process_Description:
Edits to the metadata were made to fix any errors that MP v 2.9.32 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). The link to the data in the Identification_Information section had to be fixed. Information that was in the altitude system definition was moved to the depth system definition (encoding method), and the altitude system definition was removed. Minor fixes to the attribute format for some attributes were needed. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
