Description:
Abstract:
In 2007, the U.S. Geological Survey collected 24 vibracores within Apalachicola Bay, Florida. The vibracores were collected using a Rossfelder electric 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 Administrationís (NOAA) Coastal Services Center (CSC) and the Apalachicola Bay National Estuarine Research Reserve. This report contains 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:
These data are JPEG files of seismic reflection profiles (collected in 2006; published by Twichell and others, 2007) that are adjacent to vibracores collected by the U.S. Geological Survey during a 2007 cruise within Apalachicola Bay, Florida. These data are included to give the vibracores greater stratigraphic context. JPEG format is universal and yields an easily browseable pictorial view of the seismic profiles. Each profile image is hotlinked to its corresponding trackline navigation contained within a polyline shapefile (Seismic_Cores_INT.shp). These images also have representations of vibracore locations, which show the calculated core penetration depth on the profile. Core depth was determined by assuming a constant speed of sound in sediment and seawater of 1500 m/sec.

Logical_Consistency_Report:
Seismic-reflection profiles that were adjacent to 24 vibracores collected in 2007 in Apalachicola Bay, FL were selected from a published geophysical dataset (Twichell and others, 2007). Only the profiles within the near vicinity (50 meters) of a vibracore were chosen for inclusion in this report.
Completeness_Report:
Of the 921 seismic-reflection lines collected in 2005 and 2006 (Twichell and others, 2007), only 19 were selected for inclusion in this report. These 19 seismic images represent the seismic-reflection profiles that were adjacent to the 24 vibracores collected in 2007. 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. Core 18A is not shown on the seismic-reflection profile, because core 18B is a more complete sample from the same site.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Survey lines from the SB-0512i that was towed behind the R/V Rafael are thought to have an accuracy of +/-20 meters, primarily because the towfish layback was not acounted for. Survey lines collected from the ASV (Autonomous Surface Vehicle) are expected to have higher accuracy due to the close mounted real-time kinematic GPS receiver. These data are likely accurate to +/- 5 meters.

Source_Contribution:
In order to give the vibracore data greater stratigraphic context, seismic images and trackline data from the geophysical survey completed 2006 are included in this report (Twichell and others, 2007). 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 Administrationís (NOAA) Coastal Services Center (CSC) and the Apalachicola Bay National Estuarine Research Reserve (Twichell and others, 2007). The vibracores were collected using a Rossfelder 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, 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 for radiocarbon, microfossil, and grain-size analysis.
Process_Step:
Process_Description:
The original seismic trackline shapefile was edited to include only the tracklines that were adjacent to vibracore sites. The seismic-reflection profiles (in JPEG format) corresponding to the adjacent tracklines were also selected. Seismic-reflection JPEG images were imported into Adobe Illustrator (version CS2) and vibracore locations and lengths were added to the profile. Depths on the seismic profiles are shown in two-way travel time, and core lengths were converted to travel time assuming a speed of sound in water and sediment of 1500 m/sec; or 0.75 meters/ two-way travel time in milliseconds.
