Description:

Abstract:

Geophysical and geological survey data were collected off Town Neck Beach in Sandwich, Massachusetts, in May and July 2016. Approximately 130 linear kilometers of subbottom (seismic-reflection) and 234-kilohertz interferometric sonar (bathymetric and backscatter) data were collected along with sediment samples, sea floor photographs, and (or) video at 26 sites within the geophysical survey area. Sediment grab samples were collected at 19 of the 26 sampling sites and video and (or) photographic imagery of the sea floor were taken at all 26 sites. These survey data are used to characterize the sea floor by identifying sediment-texture, seabed morphology, and underlying geologic structure and stratigraphy. Data collected during these 2016 surveys are included in this data release: https://doi.org/10.5066/P9HZHXXV.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

All attributes were evaluated during data processing as standard quality control to ensure attributes contain accurate and relevant information and values. Due to rounding, the sum of the aggregate class percentages (e.g., GRAVEL_PCT, SAND_PCT, etc.) and the sum of the phi fraction percentages (e.g., PHI_11, PHI_10, etc.) may not always add up to exactly 100.00%.

Logical_Consistency_Report:

The sediment samples were all collected with the same modified Van Veen grab sampler mounted on the MiniSEABOSS.

Completeness_Report:

Sediment samples were collected at 19 of the 26 stations. Sediment samples were only attempted in areas where collecting a sample would not damage the MiniSEABOSS; therefore, no samples were collected in areas with a cobble, boulder, or rocky seabed, as identified in real time using the top-side live video feed (stations 2016-037-003, 2016-037-004, 2016-037-021, and 2016-037-025). At three sites (stations 2016-037-001, 2016-037-002, and 2016-037-026), a sample was attempted but was not successfully collected.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Navigation for survey 2016-037-FA used Differential Global Positioning System (DGPS). The DGPS was set to receive fixes at a one-second interval in geographic coordinates (World Geodetic System of 1984 [WGS 84]). The recorded position of each sediment sample is the position of the DGPS antenna on the survey vessel, located on the aft of the R/V Rafael's cabin just port of the centerline, not the location of the MiniSEABOSS sampler. The MiniSEABOSS was deployed approximately 2 meters to the starboard side of the DGPS antenna. No layback or offset was applied to the recorded position. In addition to the +/- 2-meter offset, the sampler may drift away from the survey vessel when deployed to the sea floor. Based on the various sources of horizontal offsets, a conservative estimate of the horizontal accuracy of the sediment sample locations is 2-4 meters.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

The depths recorded for each sample are approximate and were derived from the preliminary bathymetry data collected off Town Neck Beach during the geophysical survey in May 2016 (see 2016-017-FA_Bathymetry2m_NAVD88 available from the larger work citation for the final bathymetry data).

Sediment samples were acquired using the MiniSEABOSS. The sediment data and the observations from video and still cameras are used to explore the nature of the sea floor and, in conjunction with high-resolution geophysical data, to make interpretive maps of sedimentary environments and validate acoustic remote sensing data. This setup of the MiniSEABOSS incorporates a modified Van Veen sediment sampler, two GoPro HERO4 Black digital cameras, a downward-looking SeaViewer 6000 HD Sea-Drop video camera with topside feed, and a dive light. A compass and depth sensor were attached to the sampler as well and are sometimes visible in the top-mounted GoPro to be used for troubleshooting as necessary. The elements of this particular MiniSEABOSS system are held within a stainless-steel frame that measures ~1 x 1 meters. The frame has a stabilizer fin that orients the system as it drifts over the seabed. The R/V Rafael occupied one of the target stations and the MiniSEABOSS was deployed off the vessel's starboard side. The winch operator lowered the sampler until the sea floor was observed in the top-side live video feed. The vessel and sampler drifted with wind and current for up to a few minutes to ensure a decent image with a clear view of the sea floor and then at most stations the winch operator lowered the Van Veen sampler until it rested on the sea floor. When the system was raised, the Van Veen sampler closed and collected a sample as it was lifted off the sea floor. The sampler was recovered to the deck of the survey vessel where a subsample was taken for analysis at the sediment laboratory at the USGS Woods Hole Coastal and Marine Science Center. Sediment samples were only attempted in areas where collecting a sample would not damage the MiniSEABOSS; therefore, no samples were collected in areas with a cobble, boulder, or rocky seabed, as identified in real time using the top-side live video feed. DGPS navigation from a Hemisphere DGPS receiver was logged through HYPACK navigation software and a DataBridge data logger. The DGPS was set to receive fixes at a one-second interval in geographic coordinates (WGS 84). A log file for the survey was saved in ASCII text format.

Process_Step:

Process_Description:

Twenty-six stations were occupied aboard the R/V Rafael during USGS survey 2016-037-FA with the MiniSEABOSS (Blackwood and Parolski, 2001). The MiniSEABOSS was equipped with a Van Veen grab sampler, two GoPro HERO4 Black digital cameras, and a downward-looking video camera. Physical sediment samples were collected at 19 of the 26 stations. Sediment samples were only attempted in areas where collecting a sample would not damage the MiniSEABOSS; therefore, no samples were collected in areas with a cobble, boulder, or rocky seabed, as identified in real time using the top-side live video feed. At three sites (stations 2016-037-001, 2016-037-002, and 2016-037-026), a sample was attempted but was not successfully collected. The sediment sample locations and times were recorded within the ship's HYPACK navigation system when the sampler was lifted from the seabed (the Van Veen sampler closed and collected a sample as it was lifted off the sea floor). Once the sampler was recovered, a subsample was taken for grain-size analysis at the sediment laboratory at the USGS Woods Hole Coastal and Marine Science Center.

Process_Description:

DGPS navigation from a Hemisphere DGPS receiver was logged through HYPACK navigation software and a DataBridge data logger. The DGPS was set to receive fixes at a one-second interval in geographic coordinates (WGS 84). Dates and times were recorded in Coordinated Universal Time (UTC). A log file for the survey was saved in ASCII text format. An AWK script (awkhypack.gpgga_v0_9.awk) was run on the log file to parse for the GPGGA navigation string and create an ASCII Comma Separated Value (CSV) text file. The output file was then reformatted using an AWK script (nav_time_reformat.awk), creating a final processed navigation file for the entire sampling survey.

The sediment sample times (as recorded in the HYPACK target file and the written survey log) were used to parse GPS positions for each sediment sample from the logged DGPS data. Approximate depths for each sample were derived from the preliminary bathymetry data collected off Town Neck Beach during USGS field activity 2016-017-FA. This information was then provided to the sediment laboratory at the USGS Woods Hole Coastal and Marine Science Center with the sample analysis request form.
