Description:

Abstract:

The Delmarva Peninsula is a 220-kilometer-long headland, spit, and barrier island complex that was significantly affected by Hurricane Sandy in the fall of 2012. The U.S. Geological Survey conducted cruises during the summers of 2014 and 2015 to map the inner continental shelf of the Delmarva Peninsula using geophysical and sampling techniques to define the geologic framework that governs coastal system evolution at storm-event and longer timescales. Geophysical data collected during the cruises include swath bathymetric, sidescan sonar, chirp and boomer seismic reflection profiles, grab sample and bottom photograph data. More information about the USGS survey conducted as part of the Hurricane Sandy Response-- Geologic Framework and Coastal Vulnerability Study can be found at the project website or on the WHCMSC Field Activity Web pages: https://woodshole.er.usgs.gov/project-pages/delmarva/, https://cmgds.marine.usgs.gov/fan_info.php?fan=2014-002-FA and https://cmgds.marine.usgs.gov/fan_info.php?fan=2015-001-FA. Data collected during the 2014 survey can be obtained here: https://doi.org/10.5066/F7MW2F60

Purpose:

This data set includes the locations, identifiers, grain-size ananlysis, and carbonate concentration of the coarse fraction for surficial sediments collected at 125 stations along the Delmarva Peninsula. The sediments were collected with a modified Van Veen grab on the mid-sized SEABed Observation and Sampling System (SEABOSS, SEABOSS Mark II configuration) during USGS survey 2015-001-FA, aboard the M/V Scarlett Isabella. This data set was collected to ground-truth (verify) the acoustic data sets that were acquired early during the same survey (2015-001-FA). Bottom photographs were also taken at each station occupied by the SEABOSS (see shapefile 2015-001-FA_photos.shp in larger work citation). Samples were analyzed in the sediment laboratory at the USGS Woods Hole Coastal and Marine Science Center.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

All attributes were checked in a consistent manner. The field values associated with carbonate dissolution may not add up to exactly 100 percent. However, all are within 3 percent of 100. This is due to the carbonate digestion process and the inevitable loss of material with very high carbonate concentrations.

Logical_Consistency_Report:

All samples were acquired with the same modified Van Veen Sampler mounted on a mid-sized SEABOSS (Mark II configuration). No additional checks for topological consistency were performed on this data.

Completeness_Report:

All 125 sampling stations retained a sample and all samples were analyzed for grain-size and carbonate concentration. A CSV file contains sediment lab analyses data used to create the sample shapefile.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Differential Global Positioning System (DGPS) and Wide Area Augmentation System (WAAS) enable GPS navigation data were acquired during sediment sampling with a Hemisphere receiver and recorded with HYPACK software versions 13.0.9.21 and 15.0.9.71 (www.hypack.com). The recorded position of each bottom photograph is the position of the GPS antenna on the survey vessel acquisition van, not the SEABOSS sampler. The SEABOSS was deployed approximately 5 meters astern of the GPS antenna off the ship's A-fame on the stern of the ship. No layback or offset was applied to the recorded position. In addition to the plus or minus 5 m offset the SEABOSS may additionally drift away from the survey vessel when deployed to the seafloor. Based on the various sources of horizontal error, a conservative estimate of the horizontal accuracy of the bottom photograph location is 20-30 m.

Source_Contribution:

Bottom photographs and sediment samples were acquired to validate the seafloor interpretations made from geophysical data. Often sediment samplers are unable to recover large-diameter particles, so photographs can document the seafloor character in areas where samples may not be obtained. Two GoPro cameras were mounted to a USGS SEABOSS (Mark II configuration) with a modified VanVeen sampler frame. Approximate SEABOSS dimensions are 115 X 115 X 117 cm. The Van Veen sampler is housed at the bottom and center of the frame at approximately 30 X 32 X 16 cm with a 1/10 sq. meter sample capacity. Two red lasers were mounted on the frame above the sampler, 20 cm apart for scale in bottom photographs. A Keldan (Advanced Lighting Technology) light was mounted at the top of the frame and aimed downward to illuminate the seabed for photographs. Two GoPro cameras were mounted on the frame and set to capture photographs at 2 or 5 second intervals. Samples were recovered when the frame was lifted off the seabed and triggered the Van Veen sampler to close.

Process_Step:

Process_Description:

One hundred and twenty-five target stations were sampled aboard the M/V Scarlett Isabella (USGS survey 2015-001-FA) with the mid-sized SEABOSS (Blackwood and Parolski, 2001) that was equipped with a Van Veen grab sampler, and 2 digital GoPro cameras. Physical sediment samples were collected at all 125 stations. Locations for sediment samples were manually recorded from the Hemisphere GPS during the retrieval of the SEABOSS instrument, at the start of instrument recovery when it was lifted from the seabed (the Van Veen sampler closed and collected a sample as it was lifted from the sea floor).

Process_Description:

Samples were analyzed in the sediment laboratory at the USGS Woods Hole Coastal and Marine Science Center. Coarse fraction determined by sieve; fine fraction determined by Coulter Counter. Additionally carbonate concentrations were determined through acid wash analysis on the coarse fraction. See Poppe et al. (2014) for analytical specifics for both grain size and carbonate measurement processes. Sediment statistics were recorded in MS Excel file (XLS) and saved as Comma Separated Value file (CSV).

Process_Step:

Process_Description:

In ArcMap (version 10.3.1), the ASCII comma-delimited file (2015-001-FA_samples.csv) was converted to a point feature class by selecting the 'comma separated value' text file -- Create Feature Class -- from XY table using the defined geographic coordinate system (Decimal_Degrees_WGS84.prj). The point feature class layer was then exported to a shapefile using the XTools Pro (version 12.0) -- Table Restructure tool. Field types for the PHIm4 and PHIm5 attributes were manually adjusted in XTools Pro to double precision floating point values during this step, as ArcGIS automatically read these 2 attributes as integer values.

Resource_Description:

USGS data release 2015-001-FA contains sediment sample locations, grain size and carbonate concentration analyses of the seafloor samples collected from the Delmarva Peninsula area (2015-001-FA_samples.zip). The zip file contains the following shapefile: 2015-001-FA_samples.shp and a CSV files with sample analysis (2015-001-FA_samples.csv). A browse graphic (2015-001-FA_samples_browse.jpg) and Federal Geographic Data Committee (FGDC) Content Standards for Digital Geospatial Metadata (CSDGM) metadata files (2015-001-FA_samples.xml) in four standard formats are also included in the zip file.
