Description:
Abstract:
Accurate data and maps of sea-floor geology are important first steps toward protecting habitat, delineating marine resources, and assessing environmental changes due to natural or human effects. Initiated in 2003, the primary objective of the Geologic Mapping of the Massachusetts Sea Floor program is to develop regional geologic framework information for the management of coastal and marine resources. The project is focused on the inshore waters (5–30 meters deep) of Massachusetts. This dataset is from U.S. Geological Survey (USGS) sampling survey 2011-015-FA (September 9–16, 2011) by the USGS Woods Hole Coastal and Marine Science Center and the Massachusetts Office of Coastal Zone Management with partners from the Massachusetts Division of Marine Fisheries and the U.S. Environmental Protection Agency aboard the ocean survey vessel Bold. During the survey, surficial sediment samples and bottom still and video imagery were collected in Cape Cod Bay, Buzzards Bay, and Vineyard Sound; south of Martha's Vineyard; and south and east of Nantucket, Massachusetts.
Purpose:
This dataset includes the locations and grain-size analysis or textural description of surficial sediments collected with a modified Van Veen grab on the SEABed Observation and Sampling System (SEABOSS), where operational, or the ship's Van Veen grab during USGS survey 2011-015-FA.
Supplemental_Information:
Physical sediment samples were also analyzed for benthic infauna by AECOM (see report by the Massachusetts Office of Coastal Zone Management [2012] available from the cross-reference citation). Bottom still and video imagery was also taken at most stations (see shapefiles 2011-015-FA_photos.shp and 2011-015-FA_videos.shp available from the larger work citation; see the Coastal and Marine Geology Program Video and Photograph Portal to view the bottom videos [Golden and others, 2015; link available from the cross-reference citation]).

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.
Logical_Consistency_Report:
Physical sediment samples were collected using two different devices: a modified Van Veen grab sampler mounted on a large SEABOSS, where operational, or the ship's Van Veen grab sampler. Three hundred twenty-two stations were occupied within the study area, but the SEABOSS was only operational for 246 sites. The remaining stations were occupied using the ship's Van Veen grab sampler. The station numbers (FIELD_NO) were determined before the survey and are not necessarily in sequential order of when they were occupied. Gaps in sequential station numbers exist as not all planned stations were occupied during the survey. Two sites were occupied twice on different days during the survey, so the station number for the data collected when they were occupied the second time ends in "0.2" (i.e., stations 81.2 and 95.2); these sites are considered unique stations (e.g., 81 and 81.2 are two different stations). No additional checks for topological consistency were performed on these data.
Completeness_Report:
All 322 stations that were occupied during USGS survey 2011-015-FA are included in this dataset; however, physical sediment samples were only collected at 279 of the 322 stations. For stations occupied using the SEABOSS, sediment samples were only attempted in areas where collecting a sample would not damage the SEABOSS; 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 some sites, samples were attempted one or more times in what appeared in the real-time video as sand or mud, but no sample was successfully collected. Samples were attempted at all stations occupied using the ship's Van Veen grab sampler since there was no top-side live video feed. Forty of the 43 sites with no physical sediment sample were classified by USGS geologists based on the visual observation of the last still image of the sea floor taken during the sampler deployment, which is noted in the comments field for these stations. The remaining three sites where no physical sediment sample was successfully collected (stations 167, 420, and 421) did not have any imagery with a clear view of the sea floor and were not classified. At one site (station 40), the sampler was held open by a cobble-size sediment and therefore only the single rock was recovered; the cobble was classified by the sediment lab as gravel with a phi size of -7, although it is important to note that there was no real sediment lab analysis performed for this site and the station's classification is based on visual observation. Sediment samples collected at nine sites (stations 41, 49, 53, 104, 116, 134, 221, 290, and 305) met USGS sampling protocol but were not deep enough (at least 7 centimeters deep) to meet the sediment sampling standard operating procedure of the Massachusetts Office of Coastal Zone Management (CZM); the grain-size analysis for these stations is included in this dataset and a note that these samples did not meet CZM's sampling protocol is included in the comments field. Note that the term "sediment samples" used herein may be used to describe samples as well as stations where the bottom type was determined by visual observation and no physical sediment sample was collected.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Navigation for survey 2011-015-FA used Differential Global Positioning System (DGPS). The DGPS was set to receive fixes at a two-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, not the SEABOSS or Van Veen grab sampler. The antenna was at the top of the vessel's A-frame from which the sampler was deployed, within a few meters of the sampler. No layback or offset was applied to the recorded position. In addition to the +/- 3-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 3-10 meters. The visual observation sediment sample stations occupied using the SEABOSS are not necessarily coincident with the location of the bottom imagery used to determine the sediment classification and are generally located at the start of the sampler retrieval. Three of the SEABOSS visual observation stations did not intersect a bottom video trackline and were moved to the last navigation fix along the trackline (stations 31 and 106) or last bottom photo if video was not acquired (station 65).
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The depths recorded for each sample were derived from the National Oceanic and Atmospheric Administration (NOAA) U.S. Coastal Relief Model. See the original data to determine the vertical accuracy of these depth values (link available from the cross-reference citation).

Sediment samples were acquired using the large SEABOSS, where operational, or the ship's Van Veen grab sampler. 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. The SEABOSS incorporates two video cameras (one forward-looking so that a shipboard operator can monitor for proper tow depth and obstacles, and one downward-looking that overlaps with the field of view of the still camera), a still camera, and a modified Van Veen sediment sampler. The elements of this particular SEABOSS system are held within a stainless-steel frame that measures 1.1 x 1.1 meters. The frame has a stabilizer fin that orients the system as it drifts over the seabed. The OSV Bold occupied one of the target stations and the SEABOSS was deployed off the vessel's A-frame on the stern of the ship. 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 sea floor was sampled with the SEABOSS's integrated Van Veen grab. Sediment samples were only attempted in areas where collecting a sample would not damage the SEABOSS; 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. The system was then raised and recovered to the deck of the survey vessel. The SEABOSS was only operational for 246 of the 322 stations occupied during this survey. The SEABOSS's still camera was occasionally malfunctioning, so use of the SEABOSS was halted partway through the survey and the remaining stations were occupied using the ship's Van Veen grab sampler equipped with a GoPro HD HERO camera and dive lights. The ship's sampler was deployed off the vessel's A-frame on the stern of the ship and lowered until the sea floor was sampled, then raised and recovered. There was no top-side live video feed, so the vessel and sampler did not drift over the seabed, video was not collected, and samples were attempted at all stations occupied using the ship's Van Veen grab sampler.

Process_Description:
Three hundred twenty-two stations were occupied aboard the OSV Bold during USGS survey 2011-015-FA with the large SEABOSS (Blackwood and Parolski, 2001), where operational, or the ship's Van Veen grab sampler. The SEABOSS was equipped with a Van Veen grab sampler, a still camera, and two video cameras (forward- and downward-looking). The still camera was occasionally malfunctioning, so the SEABOSS was only operational for 246 of the 322 stations. The remaining stations were occupied using the ship's Van Veen grab sampler equipped with a GoPro HD HERO camera and dive lights. Physical sediment samples were collected at 279 of the 322 stations. Locations for sediment samples were manually recorded from the DGPS receiver at the start of the sampler retrieval when it 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, the sample was divided in the Van Veen grab using an acrylic sheet. One side was used for grain-size analysis, while the other side was processed for benthic infaunal analysis by AECOM (see report by the Massachusetts Office of Coastal Zone Management [2012] available from the cross-reference citation). The sediment grab needed to be at least 7 centimeters deep to meet CZM's sediment sampling standard operating procedure. Some grabs were not deep enough for CZM's sampling protocol, but a sample was still collected for USGS. The grain-size analysis for these sites is included in this dataset and a note that these samples did not meet CZM's sampling protocol is included in the comments field.

A shapefile was created using the sediment grain-size analysis CSV file in Esri ArcGIS (version 10.1). Stations with no physical sediment sample were included in the shapefile and classified by USGS geologists based on the visual observation of the last still image of the sea floor taken during the sampler deployment. Three sites (stations 167, 420, and 421) did not have a physical sediment sample or any imagery with a clear view of the sea floor and were therefore not classified, but the station locations are still included in this dataset.

Process_Description:
Three of the SEABOSS visual observation stations were moved in Esri ArcGIS (version 10.3.1) because they did not intersect a bottom video trackline or bottom still image; these stations were moved to the last navigation fix along the trackline (stations 31 and 106) or last bottom photo if video was not acquired (station 65). The latitude and longitude of the edited points were calculated using the Calculate Geometry tool (Property=Y Coordinate of Point and X Coordinate of Point, respectively; Use coordinate system of the data source=WGS 1984; Unit=Decimal Degrees). XTools Pro (version 12.0) for Esri ArcGIS (version 10.3.1) was used to edit field types in the point shapefile (Table Operations - Table Restructure). The field calculator in Esri ArcGIS (version 10.3.1) was used to calculate no data values as needed. The shapefile's attribute table was exported and saved as a CSV file. The FID field was deleted in the CSV file.
