The U.S. Geological Survey (USGS) conducted a geophysical and sampling survey in October 2014 that focused on a series of shoreface-attached ridges offshore of western Fire Island, NY. Seismic-reflection data, surficial grab samples and bottom photographs and video were collected along the lower shoreface and inner continental shelf. The purpose of this survey was to assess the impact of Hurricane Sandy on this coastal region. These data were compared to seismic-reflection and surficial sediment data collected by the USGS in the same area in 2011 to evaluate any post-storm changes in seabed morphology and modern sediment thickness on the inner continental shelf. For more information about the WHCMSC Field Activity, see: https://cmgds.marine.usgs.gov/fan_info.php?fan=2014-009-FA.
This data set includes the locations, identifiers, and grain-size analysis for surficial samples collected at 25 sample locations offshore of Fire Island, NY by the U.S. Geological Survey during cruise 2014-009-FA in 2014. This data set was collected to ground-truth (verify) acoustic data collected during USGS cruise 2014-009-FA.

All attributes were evaluated during data processing as standard quality control to ensure attributes contain accurate and relevant information and values.
All samples were collected 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 these data.
Sediment samples were collected at all 25 sampling stations. All samples were analyzed for grain-size. A CSV file contains sediment lab analysis data used to create the sample location shapefile.
Differential Global Positioning System (DGPS) navigation data were acquired with Ashtech Proflex 800 and BR2G receivers and recorded with HYPACK (www.hypack.com). The Ashtech Proflex 800 receiver was mounted as the center receiver on the polemount used to test a RESON T20-P multibeam sonar. The Ashtech BR2G receiver was mounted on the aft, port-side of the acquisition van. The Ashtech Proflex 800 was used as the primary DGPS receiver until JD299 18:04. The Ashtech BR2G receiver was used as the primary receiver JD299, starting at 18:04. Layback was not incorporated into sample positions. The recorded position of each sample is the position of the DPGS antenna, not the SEABOSS sampler. In addition, the SEABOSS may 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 sample locations is assumed to be plus or minus 20 to 30 m. The SEABOSS was deployed approximately 5 meters astern of the RTK-GPS antenna for samples 1 through 19, and approximately 3 meters astern of the DGPS antenna for samples 20 through 25.

Sediment sample locations with sediment grain size analysis
The SEABed Observation and Sampling System (SEABOSS) was designed by the U.S. Geological Survey (USGS) for rapid and effective collection of seabed images and sediment samples in coastal regions. The observations from video and still cameras and the sediment data are used to explore the nature of the seafloor and, in conjunction with high-resolution geophysical data, to make interpretive maps of sedimentary environments and validate the acoustic remote sensing data. This particular setup of the SEABOSS was simplified using only GoPro cameras and dive lights to collect sea floor photographs and video without a top-side live video feed. Samples were recovered when the frame was lifted off the seabed and triggered the Van Veen sampler to close.
In general, the SEABOSS is a simple system that can be deployed from both small and large surface vessels and operates in water depths up to 200m. It typically incorporates two video cameras, a still camera, a depth sensor, and a modified Van Veen sediment sampler. The elements of this particular SEABOSS system are held within a stainless steel framework that measures 1.1 x 1.1 meters and weighs 167 kilograms overall. The frame has a stabilizer fin that orients the system as it drifts over the seabed. The SEABOSS was deployed from the M/V Scarlett Isabella off the ship's A-frame on the stern of the ship. The vessel occupied one of the target stations and deployed the SEABOSS. The winch operator lowered the sampler until the seafloor was sampled. On most stations, the vessel and sampler drifted with wind and current for a few tens of seconds to let the bottom settle and ensure a decent image. The system was then raised and recovered to the deck of the survey vessel.
Twenty-five target locations were sampled aboard the M/V Scarlett Isabella during USGS Cruise 2014-009-FA with the modified SEABOSS (Blackwood and Parolski, 2001) that was equipped with a Van Veen grab sampler, and two GoPro cameras (Hero 3+ Black, and Hero2) collecting video and photographs. Physical sediment samples were collected at all 25 samples. Time and locations for sediment samples were manually recorded from the Ashtech BR2G and Proflex 800 receivers during retrieval of the SEABOSS, as it was lifted off the sea floor.

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. See Poppe et al. (2014) for analytical specifics for grain size measurement processes. Sediment statistics were recorded in MS Excel file (XLS) and saved as Comma Separated Value file (CSV).

In ArcMap (version 10.3.1), the ASCII comma-delimited file (2014-009-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.
