Abstract:
In 2006 and 2007, the U.S. Geological Survey (USGS) and collaborators at the University of New Orleans (UNO) collected high-resolution seismic profiles and subsurface cores around the Chandeleur and Breton Islands, Louisiana. To ground-truth the acoustic seismic surveys conducted in 2006, 124 vibracores were acquired during the 07SCC04 and 07SCC05 cruises in 2007. These cores were collected within the back-barrier, nearshore, and offshore environments. The surveys were conducted as part of a post-hurricane assessment and sediment resource inventory for the Barrier Island Coastal Monitoring (BICM) project. Vibracores were collected offshore using the USGS R/V G.K. Gilbert, while the terrestrial, back-barrier, and nearshore vibracores were collected from the UNO R/V Greenhead. This report serves as an archive of sediment data from two concurrent vibracore surveys (cruises 07SCC04 and 07SCC05) from around the Breton and Chandeleur Islands in 2007 and also documents sediment data from vibracores collected offshore of the Chandeleur Islands in 1987 (cruise 87039). The 1987 vibracores were collected through the collaborated efforts of the USGS,Louisiana Geological Survey (LGS), and Alpine Ocean Seismic.
Purpose:
The 07SCC04 and 07SCC05 core locations were selected to ground-truth stratigraphic interpretations from seismic profiles acquired during previous surveys (Baldwin and others, 2009; Twichell and others, 2009) and to directly sample stratigraphic variation in the study area (Flocks and others, 2009). Additionally, this report archives the 87039 cruise vibracores collected offshore of the Chandeleur Islands in 1987. The CI_87 vibracores were collected to ground-truth the stratigraphic interpretations from seismic profiles acquired in 1987 (Kindinger and others, 1989; Kindinger and others, 1991; Brooks and others, 1995).
Supplemental_Information:
The USGS St. Petersburg Coastal and Marine Science Center (SPC&MSC) - in St. Petersburg, FL, assigns a unique identifier to each cruise or field activity. For example, 07SCC04 designates the year the data were collected (2007) for the Subsidence and Coastal Change (SCC) cruise identifier, and the field activity number (04) denotes the fourth SCC field activity of the year. Similarly, 87039 is a USGS Woods Hole Science Center (Woods Hole,MA) cruise identifier. Refer to http://walrus.wr.usgs.gov/infobank/programs/html/definition/activity.html for a detailed description of the method used to assign the cruise ID. More information on all field activities can be found in the Field Activity Collection System (FACS) logs and scanned observer's logbooks (Field Logs), as well as formal FGDC Metadata (07SCC04, 07SCC05, and 87039). A standardized naming convention was established to allow for better management of vibracores that can be identified by cruise and core number. The naming convention used for each core is as follows: yyabc##, where 'yy' are the last two digits of the year in which the core was collected, 'abc' is a 2- or 3-letter abbreviation for the cruise location or project type (for example, BI for Breton Island or SCC for Subsidence and Coastal Change), and '##' is a 2-digit number representing a specific core. Vibracores collected by the USGS R/V G.K. Gilbert (cruise 07SCC04) are identified by 07SCC## and offshore Breton Island, 07BI##. The terrestrial, back-barrier, and nearshore vibracores collected from the R/V Greenhead (cruise 07SCC05) are identified as 07SCC_##Gh. For 07SCC05 vibracores, the identifier is modified with '_##dd', the 'dd' being a two-letter abbreviation representing the research vessel from which the core was taken. Vibracores collected in 1987 are identified by a similar naming convention 'ab_yy_##'; these offshore vibracores collected from cruise 87039 are identified as CI_87_##. Detailed information about each cruise can be found in the digital FACS and equipment logs, in the Field Logs section. This report is divided into thirteen sections: Home page, Acronyms and Abbreviations, Disc Contents, Methods, Maps, Core Data Table, Core Description Sheets, Digitized Core Logs, Grain-Size Data, Core Photographs, Field Activity Logs, Federal Geographic Data Committee (FGDC) Metadata, and Software.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The validity or accuracy of core description sheets and digitized core logs is highly qualitative and depends on describer's discretion and interpretations, and physical variables such as software and operating conditions for the digitizing equipment. Visual inspection of the processed digitized profile images rendered from the handwritten description sheets did not show any major anomalies. Grain-size data for 07SCC04 and 07SCC05 cruises rendered a quantitative and fairly accurate account of the grain-size distribution throughout the cores. The sand percentages reported for 07SCC04 and 07SCC05 cruises were observed and analyzed. The accuracy of mapped core locations is based on coordinates and GPS noted in handwritten logbooks in the field. These field notes can be found as FACS logs or on the logbook page and within the FACS folder. The map datasets include 07SCC04, 07SCC05, and 87039 cruises and display vibracore locations. Note: The maps presented here are NOT for navigational purposes.
Logical_Consistency_Report:
This dataset derives from several cruises with consistent instrument calibrations. However, acquisitions of core sites during 07SCC04 and 07SCC05 cruises were acquired using differential GPS in WGS84. The acquisitions of core sites during 87039 cruise was with Loran C, satellite, and gyrocompass.
Completeness_Report:
These data were collected from multiple sources aboard multiple cruises and are therefore inherently incomplete. However, care was taken to make this a comprehensive archive combining the geologic details of all sediment cores collected for the 07SCC04, 07SCC05, and 87093 cruises. Cruise-specific completeness information is as follows. Cruise 07SCC04: As a result of a recording error in the field, there is no core 07SCC79. Core 07SCC_55_v2 (alternatively labeled CI_87_55_v2) was collected from the same location as the CI_87_55 core from the 87039 cruise. There are seven additional cores named for their location near Breton Island: 07BI_02 though 07BI_08. For unknown reasons there was no core 07BI_01. A total of 91 cores was collected on this cruise. Cruise 07SCC05: A total of 33 cores were collected on this cruise. Cruise 87039: Four cores (CI_87_01_Curlew,CI_87_02_Curlew, CI_87_03_Curlew, and core CI_87_07_Curlew) were given a more descriptive core ID to indicate their location near Curlew Island; digitized core logs are not available for these four cores. The Core Data Table contains two entries for core CI_87_20. The first was described by Jack Kindinger (USGS) and was assigned the core ID CI_87_20A for this archive; the second was described by Dr. Gregg Brooks (Eckerd College) and was assigned CI_87_20B. No grain-size data analyses or core photographs exist for the CI_87 cores.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Positions of the cores were recorded and written in the field logbooks. Each core location for the 07SCC04 and 07SCC05 cruises was obtained by differential GPS. For positional accuracy for 87039 cores please refer to the publications cited and the Metadata Cruise Report (http://quashnet.er.usgs.gov/data/1987/87039/archive/87039rpt.pdf), or the FACS Logs page, or contact Alpine Ocean Seismic. For all GIS shapefiles, horizontal positions are specified in geographic coordinates. Latitudes and longitudes values are specified in WGS84 and reprojected to North American Datum of 1983 in decimal degrees.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
These data are not to be used for bathymetry. Vibracore data are relative to sea level. However, varying recorded static shifts of the data have been known to occur. The core and water depths are located on the vibracore description profiles and are recorded in the 07SCC04 and 07SCC05 logbooks. Water depths for 07SCC04 cores were recorded by a depth finder on the R/V G.K. Gilbert. The recovery lengths of the vibracore are recorded in the logbook for most cores of each cruise. To view vertical positional accuracy of 87039 cores, please refer to the publications cited and the Metadata Cruise Report (http://quashnet.er.usgs.gov/data/1987/87039/archive/87039rpt.pdf), or the FACS Logs page, or contact Alpine Ocean Seismic.

Process_Step:
Process_Description:
Vibracore location map creation: Latitudes and longitudes for vibracore locations were transferred from written field logbooks into excel files and values were processed to decimal degrees in North American Datum of 1983. The files were imported to ArcGIS 9.3 to create shapefiles, metadata, .mxd, andJPEG files. To create vibracore location maps for HTML pages, provided within this archive, the JPEG files were exported to Adobe Illustrator for further editing and saved in JPEG format. The coordinates for the 87039 cruise cores were obtained from the Infobank (Metadata Cruise Reporthttp://quashnet.er.usgs.gov/data/1987/87039/archive/87039rpt.pdf) and publication source citation below. The USGS is the originator of all shapefiles.

Process_Step:
Process_Description:
Core Collection: Two similar types of vibracore systems were used to collect the 07SCC04 and 07SCC05 vibracores: 6.1-m and 9.1-m long aluminum core barrels were vibrated into the sediment using either a Rossfelder model P-3 electric motor (cruise 07SCC04 aboard the R/V G.K. Gilbert) or a Stow G-500 gas motor (cruise 07SCC05 aboard the R/V Greenhead). The 87039 (or CI_87) vibracores were taken by Alpine Ocean Seismic using a 12-m-long Alpine-type pneumatic vibracore apparatus (Kindinger and others, 1989; 1991; Brooks and others, 1995).
Process_Date: 2007
Process_Step:
Process_Description:
Core Description Sheets: Vibracores collected from the 07SCC04 and 07SCC05 surveys were transported to the core analysis laboratory at UNO for description, sampling, and archiving. Vibracores were cut lengthwise, and in some cases a sonicating knife was used to obtain a clean, undisturbed surface on one-half of the vibracore, lengthwise. This section was used to describe the core's contents on a core description sheet. Description includes, but is not limited to, sedimentary texture, observed sand, silt, and clay percents, bioturbation, shell abundance, sedimentary structures, physical characteristics, stratification type, interval sampled type, sample location information, and any other qualitative descriptions.
Process_Date: 2008
Process_Step:
Process_Description:
Digitized Core Logs: This process required hand digitizing a paper copy of the core description sheets using a digitizing tablet; data were converted to an electronic spreadsheet format (Microsoft Excel) using a Visual Basic macro program. This macro program produced a spreadsheet-style output of the description sheet as XLS files that were saved as PDF and JPEG files for the HTML-based format used to present these data in the various parts of this archive. Information on the digitizing process can be found in Flocks (2004; 2008)(or Methods and Software page in this report). For step-by-step instructions on the process please contact James Flocks (jflocks@usgs.gov) for more information.

Process_Description:
Core Photographs: Photographs the 07SCC04 and 07SCC05 vibracores were taken to visually represent the general physical properties of the core. To preserve detail about sediment texture, color, composition, bedding, and other physical characteristics recorded on the core description sheets can also be observed on the core photographs.
Process_Date: 2008
Process_Step:
Process_Description:
Grain-Size Data: Sediment samples from the 07SCC04 and 07SCC05 vibracores were analyzed at the USGS SPC&MSC (St. Petersburg, FL) using a Beckman Coulter LS 200 particle-size analyzer. The LS 200 uses laser diffraction to quickly and accurately measures the size distribution of sedimentary particles ranging from 0.0004 mm and 2 mm in diameter, providing quantitative measurements of size distribution in a customizable data output. Statistical moments that correspond to sorting, skewness, and kurtosis were also calculated following the procedure outlined in Folk (1968). Percent sand, silt, and clay were reported for each core interval as tables provided in the Core Data Table.
Process_Date: 2009
Process_Step:
Process_Description:
Core Data Table: All of the above core data can be found in the Core Data Table (Data_Table.html) for the 07SCC04, 07SCC05, 87039 cruises. This data table can be accessed by the section links at the top and bottom of each page in this archive or by navigating to the individual cores located on the Study Area Map. Clicking on a core's mapped-point or core ID on the Area Map pages will access the specific core's information in the Core Data Table. The first column of the table contains Core ID, and four other columns contain previews and downloadable files for Core Description Sheets, Digitized Core Logs, Grain-Size Data, and Core Photographs pertaining to each Core ID row.
