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 navigation data are provided in three different formats: *.raw as an archive of the navigation data files acquired during the survey in the original collected format as well as in reformatted CSV and XLSX formats. The reformatted files add additional information, and most significantly provide that navigation in decimal degrees.

Data_Quality_Information:
Logical_Consistency_Report:
The navigation was downloaded at the end of the cruise and is available in $GPGGA format given to the scientist by the ship, as well as reformatted files for easier use. GPGGA is a National Marine Electronics Association (NMEA) sentence for Global Positioning System fix data that includes time, position and fix related data for a GPS receiver. The reformatted version of the navigation excludes the transit navigation between the port and the study area. The original GPGGA navigation filenames are in the format AUK2019008_XXXX_UTC_nav_raw.csv where XXXX is the day of navigation (for example 30jul2019). The filenames of the reformatted navigation are in the format AUK2019008_station_nav_log_XXXX_UTC where AUK2019008 is the cruise ID, and XXXX is the day of navigation (for example 30JUL2019); the filename suffix is either XLSX or CSV.
Completeness_Report:
The raw navigation files (with the $GPGGA string) represent all the navigation acquired on the cruise and is what is used to determine the bounding coordinates of the dataset. 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.
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).

Process_Description:
Raw CSV files: AUK2019008_XXXX_UTC_nav_raw.csv
The files *_raw.csv are the $GPGGA strings of the raw navigation recorded on the ship each day. The first row in each file describes the file.
For the remaining rows, the format of the columns of information is as follows:
$GPGGA, UTC time, latitude (DDMM.MMMM), latitude hemisphere, longitude (DDMM.MMMM), longitude hemisphere.

Process_Description:
Reformatted XLSX files: AUK2019008_station_nav_log_XXXX_UTC.xlsx
The $GPGGA strings have the latitude and longitude in the degrees decimal minutes format DDMM.MMMM with the hemisphere indicated (N for North and W for West). These data were brought into a Microsoft Excel spreadsheet (version 2016) 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 XLSX spreadsheet was opened in Microsoft Excel (2016). The first row (the explanation header) and the second row (descriptive column headers) were deleted and the third row (brief column headers that are compatible with importing the data into a GIS) was retained. Then the spreadsheet was exported as an MS-DOS CSV file with the same prefix filename as the Excel file.
