Title:
PDF images of field description sheets from vibracores collected by the U.S. Geological Survey within Apalachicola Bay, Florida, 2007
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.

Why was the data set created?

PDF images of each vibracore field description sheet for 24 vibracores collected by the U.S. Geological Survey during a 2007 cruise within Apalachicola Bay, Florida were generated in order to incorporate the raw core notes into electronic format. These field notes are the basis from which the core summaries are derived.

    Source_Contribution:
    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, deployed, 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) 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.
  2. How were the data generated, processed, and modified?
    Date: 2007 (process 1 of 6)
    Hand-written core description log sheets were filled out for each core using standard core description techniques. Each core description sheet covered 1-m of the core length, so several sheets were needed to describe each core. Heading information was included on each sheet regarding the cruise, core number, describer, general geographic description of the core location, and whether the core was to be processed for optically stimulated luminescence (OSL) dating. Core description details and field notes included: the lithologic units, sedimentary structures, biota, and a depiction of each 1-meter stratigraphic column. Person who carried out this activity:

    All core field description sheets for the 24 collected vibracores were scanned using a Xerox Workcentre Pro C236 copy machine. This document machine automatically generates an electronic PDF document of the original scanned document. All field sheets for an individual core were save electronically and grouped into one multi-page PDF document (per core) using Adobe Acrobat Professional (version 8.0).

    Edits to the metadata were made to fix any errors that MP v 2.9.36 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.). Attempted to modify http to https where appropriate. Added a link in the identification section to the catalog html page. The distribution format name was modified in an attempt to be more consistent with other metadata files of the same data format. 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. Person who carried out this activity:

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    There are no attributes associated with these PDF documents
  2. How accurate are the geographic locations?
    The station location reported on the top of each core log sheet is for relative geographic purposes, and should not be used for precise core locations. The Differential Global Positioning System latitude and longitude for each core is recorded in the 'App07-CoreLocation' file included in this report, and these positions are assumed to be accurate within +/- 20 m.
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    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. All 24 vibracore field descriptions were scanned to digital PDFs.
  5. How consistent are the relationships among the observations, including topology?
    Core field descriptions were scanned and converted to PDF format in order to maintain a digital record of the data. All cores were described by the same interpreter, and standard core description techniques were used.
