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. The work 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 a total of 233 locations on Stellwagen Bank during six separate surveys from May 2016 to April 2019. During these surveys 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 including temperature, salinity, density, and fluorescence. Purpose: These navigation data are provided in three different formats: raw data in the original collected format (*raw.csv) as an archive of the navigation data files acquired during the survey as well as in reformatted CSV and XLSX formats. The reformatted files add additional information, and most significantly provide the navigation in decimal degrees. Supplemental_Information: Additional information regarding the field activities associated with these data can be obtained from the following locations https://cmgds.marine.usgs.gov/fan_info.php?fan=2016-012-FA, https://cmgds.marine.usgs.gov/fan_info.php?fan=2016-039-FA, https://cmgds.marine.usgs.gov/fan_info.php?fan=2018-027-FA, https://cmgds.marine.usgs.gov/fan_info.php?fan=2018-028-FA, https://cmgds.marine.usgs.gov/fan_info.php?fan=2018-029-FA, and https://cmgds.marine.usgs.gov/fan_info.php?fan=2019-007-FA .

Online_Linkage: https://doi.org/10.5066/P9FWFLPD Online_Linkage: https://www.sciencebase.gov/catalog/item/5d95153ee4b0c4f70d10a4f7 Data_Quality_Information: Logical_Consistency_Report: The raw navigation was downloaded at the end of each cruise and given to the chief scientist. For five of the field activities, the raw navigation is in $GPGGA format (2016-012-FA, 2016-039-FA, 2018-028-FA, 2018-029-FA, and 2019-007-FA). For one field activity (2018-027-FA), the raw navigation is in $IIGGA format. GGA is a National Marine Electronics Association (NMEA) sentence for Global Positioning System (GPS) fix data that includes time, position and fix related data for a GPS receiver, and the information contained in the files is the same whether it has the $GPGGA or $IIGGA NMEA tag. All of the raw navigation was reformatted and excludes the transit navigation between the port and the study area. The original raw navigation filenames are in the format AUKYYYYYYY_XXXX_UTC_nav_raw.csv where YYYYYY is the field activity identifier (for example 2016012), and XXXX is the day of navigation (for example 18may2016). All of the raw navigation files have the CSV file extension. The filenames of the reformatted navigation are in the format AUKYYYYYYY_station_nav_log_XXXX_UTC where YYYYYYY is the cruise ID (for example 2016012), and XXXX is the day of navigation (for example 18MAY2016); the file extension is either XLSX or CSV. All the field activities took place on the Stellwagen Bank National Marine Sanctuary's research vessel, R/V Auk. Although these data represent six separate field activities, the set-up and acquisition on all the cruises is consistent with the exception of the navigation - which was sometimes acquired at 1-second intervals and sometimes at 2-second intervals. Completeness_Report: The raw navigation files (with the $GPGGA or $IIGGA string) represent all the navigation acquired on the cruises, including transit lines. These files are the original files handed over to the scientist from the ship personnel. The reformatted navigation files do not include the transit navigation between the port and the study area. No other navigation fixes were removed, so the data could include bad navigation fixes, missing fixes, and duplicates. The bounding coordinates represent the extent of the raw navigation data. The ranges of values in the entity and attribute section are from the reformatted navigation with the transit navigation fixes removed. 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) in geographic coordinates (World Geodetic System of 1984 [WGS 84]) with a horizontal accuracy of 10 m. For two cruises (2018-027-FA and 2019-007-FA) the navigation was acquired at one-second intervals. Four cruises (2016-012-FA, 2016-039-FA, 2018-028-FA, and 2018-029-FA) acquired navigation at a two-second interval. The navigation antenna was located 5.3 m forward of the SEABed Observation and Sampling System (SEABOSS) deployment location. This offset was not accounted for in the navigation acquisition so navigation fixes represent the antenna location. Lineage: Process_Step: Process_Description: Raw CSV files: AUKYYYYYYY_XXXX_UTC_nav_raw.csv The files *_raw.csv are the GGA strings of the raw navigation recorded on the ship each day. The first row in each file describes the file. > For the remaining rows of the $GPGGA files (2016-012-FA, 2016-039-FA, 2018-028-FA, 2018-029-FA, and 2019-007-FA), the format of the columns of information is as follows: > $GPGGA, Coordinated Universal Time (UTC) in the format HHMMSS, latitude (DDMM.MMMM), latitude hemisphere, longitude (DDMM.MMMM), longitude hemisphere. For the remaining rows of the $IIGGA files (2018-027-FA), the format is as follows: > $IIGGA, UTC time (HHMMSS), latitude (DDMM.MMMM), latitude hemisphere, longitude (DDMM.MMMM), longitude hemisphere. Data were collected from 2016 to 2019 with the process date representing the most recent acquisition year.

These data were brought into an Excel spreadsheet and converted to decimal degrees using the following formula examples: latitude: (4211.9672-4200)/60+(42) to give 42.19945 decimal degrees longitude: ((7043.2105-7000)/60 + 70​) * -1 to give -70.72018 decimal degrees with negative for western hemisphere Additional fields of information were added to the spreadsheet and are defined in the entity and attribute section, as well as within the header information in each spreadsheet. The first row is an explanation header, the second row contains descriptive column headers, and the third row contains brief column headers that are compatible with importing the data into a GIS. The reformatted version of the navigation excludes the transit navigation between the port and the study area. The data were reformatted shortly after collection, with data collection occurring from 2016 to 2019. The process date represents the most recent acquisition year.
