Description:
Abstract:
This field activity is part of the effort to map geologic substrates of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts. The overall goal is to develop high-resolution (1:25,000) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics. This cruise was conducted in collaboration with the Stellwagen Bank National Marine Sanctuary, and the data collected will aid research on the ecology of fish and invertebrate species that inhabit the region. The Sanctuary's research vessel, R/V Auk, visited 53 locations on Stellwagen Bank at which a customized Van Veen grab sampler (SEABOSS) equipped with a video camera and a CTD was deployed in drift mode to collect sediment for grain-size analysis, video imagery of the seabed, and measurements of water column properties.
Purpose:
These sediment samples analyzed for grain-size composition, along with seabed imagery, will be used to describe the surficial geological substrates present in the study area.

Data_Quality_Information:
Logical_Consistency_Report:
The Excel spreadsheet is the original file returned to the scientist after analysis in sediment laboratory at the USGS Woods Hole Coastal and Marine Science Center. Station 4917 had to have the longitude adjusted to the correct value.
Completeness_Report:
These data represent all the sediment samples collected as part of the field activity. However, a sample was not acquired at every station. Samples were discarded at sea if the sediment composition was visibly altered during collection, for example if the sampler did not close properly causing sediment to be lost during recovery of the sample. A total of 44 sediment samples were collected; stations without samples are: 4902, 4905, 4908, 4913, 4926, 4927, 4928, 4930, and 4943.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The location information for stations was acquired from a satellite navigation receiver (Furuno satellite compass SC-30 GPS receiver) at two-second intervals with a horizontal accuracy of 10 m. The navigation antenna is located 5.3 m forward of the SEABOSS deployment location. This offset was not accounted for in the navigation acquisition (navigation fixes represent antenna location). The SEABOSS may also drift away from the survey vessel when deployed to the sea floor.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Water depth was determined using a Simrad ES60, 120 kHz, single beam echo-sounder using a 120-25 transducer, which detects the seabed to a depth of 800 m. Depth values were rounded to the nearest meter to account for ship motion

Process_Description:
Sediment sampling methods:
As a part of the process of mapping the sea floor, the USGS developed the SEABed Observation and Sampling System (SEABOSS) to collect samples and video and photographic images of the seabed to aid in the interpretation of seabed sonar imagery. A modified Van Veen sediment grab sampler is mounted in the center of the SEABOSS frame, which ensures the sampler is properly oriented on the seabed when a sample is collected. Before deployment, the sampler bucket jaws are opened by collapsing the extended arms to a near-horizontal position and locking them in place with two catches. The sampler operates passively to sample the seabed; it is not spring loaded.
To collect a sediment sample, the SEABOSS frame was lowered gently onto the seabed, reducing tension on the cable, which caused the two locking catches to be automatically released by gravity. As the cable was retrieved, the grab sampler arms were pulled upward, closing the bucket around the sediment, and the SEABOSS was lifted off the seabed.
The SEABOSS was retrieved and set upon a wooden platform that kept the sampler bucket and camera systems above the deck. The sampler arms were held in the upright position manually or by tension on the cable, the two doors on the upper side of the bucket were opened, and the sediment surface was photographed before the sediment was removed. For this project, the upper 2 cm of sediment, representing the surface of the seabed, were removed with a rectangular shovel 2-cm deep and stored in a plastic bag for grain-size analysis. The remaining sediment was dumped into a tray on the deck below the sampler and discarded, after which the sampler was washed in preparation for sampling at the next site. Further information on the SEABOSS can be found in Blackwood and Parolski (2001) and Valentine and others (2000).

Samples were analyzed in the sediment laboratory at the USGS Woods Hole Coastal and Marine Science Center. Coarse fraction (particles greater than 63 microns in diameter) determined by sieve; fine fraction (particles less than 63 microns in diameter) determined by Beckman Coulter Multisizer. See Poppe and others (2014) for analytical specifics for grain size analysis. Sediment statistics were recorded in Microsoft Excel file and returned to the scientist.

Process_Description:
Using ArcGIS 10.6.1, the CSV file was converted to a shapefile within ArcMap using File - Add Data - Add XY data. The CSV file was selected, with the x-coordinate set to LONGITUDE and the y-coordinate set to LATITUDE. The coordinate system of the input coordinates was set to the geographic coordinate system GCS_WGS_1984. Once the XY event layer was added to ArcMap, the data were then converted to a shapefile by right-clicking on the event theme in the contents pane - Data - Export Data. All of the features were exported using the layer's source data for the coordinate system. The output shapefile was set to 2019-008-FA_sedsamps.shp.

Attribute_Definition:
Quality grades for sample data are assigned based on the calculated percent difference between the weights of the coarse fraction remaining after wet sieving and the sum of all of the weighed fractions after dry sieving the coarse fraction, indicating an estimated differing amount of material which could skew the calculated grain size results. A quality grade is assigned as well as the initials of the person that assigned the grading in the format Q-XX where Q is the quality grade and XX are the initials of the person assigning the grade.

Overview_Description:
Entity_and_Attribute_Overview:
These attribute definitions describe each column of information in the Excel spreadsheet with the exception of additional information in the last column of the Excel spreadsheet which contains an explanation of the QUALITY_GR values and how the quality grade is assigned. That column of information is omitted from the CSV file and shapefile. The first row of the spreadsheet is the column heading. The CSV file has the same information and the same column definitions except the last column of the XLSX file is omitted (data quality grade explanation). The information in the last column of the XLSX file is as follows:
Data quality grades may be determined by several factors, and any comments or notes that indicate the data for a particular sample may be suspect are included in the results table for that sample under "comments". Quality grades for sample data that do not have any additional comments are assigned based on the calculated percent difference between the weights of the coarse fraction remaining after wet sieving and the sum of all of the weighed fractions after dry sieving the coarse fraction, indicating an estimated differing amount of material which could skew the calculated grain size results.
A = percent differences between 0% and +-1.5%
B = percent differences between +-1.5% and +-3%
C = percent differences between +-3% and +-4.5%
D = percent differences greater than +-4.5%
