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 13 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 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.
Supplemental_Information:
Additional information regarding the field activity can be obtained from https://cmgds.marine.usgs.gov/fan_info.php?fan=2017-009-FA.

Data_Quality_Information:
Logical_Consistency_Report:
The navigation was downloaded at the end of the cruise and is available in the original GPGGA format as well as reformatted for easier use. The filenames indicate the cruise and day of navigation. 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 AUK2017009_XXXX_UTC_nav_raw.csv where XXXX is the day of navigation (for example 30jan2017). The filenames of the reformatted navigation are in the format AUK2017009_station_nav_log_XXXX_UTC where XXXX is the day of navigation (for example 30JAN2017). 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. These files are the original files handed over to the scientist. The reformatted navigation files have removed the transit navigation to and from port to the study area. No other navigation fixes were removed, which could include bad navigation 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).
Lineage:
Process_Step:
Process_Description:
The files *_raw.csv are the $GPGGA strings of the raw navigation recorded on the ship each day.
The format of the columns of information are as follows:
$GPGGA, UTC time, latitude (DDMM.MMMM), latitude hemisphere, longitude (DDMM.MMMM), longitude hemisphere.
The first row in the file contains the filename and not the column headers of the data.

Process_Description:
The $GPGGA strings have the latitude/longitude in the format DDMM.MMMMM with the hemisphere indicated (N for North and W for West). 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
Additional fields of information were added to the spreadsheet and are defined in the entity and attribute section, as well as within 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 filenames indicate the cruise and day of navigation. 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 AUK2017009_XXXX_UTC_nav_raw.csv where XXXX is the day of navigation (for example 30jan2017). The filenames of the reformatted navigation are in the format AUK2017043_station_nav_log_XXXX_UTC where XXXX is the day of navigation (for example 30JAN2017); the filename suffix is either XLSX or CSV.

The spreadsheet was opened in Excel (2010). 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.

Overview_Description:
Entity_and_Attribute_Overview:
The attribute label is the abbreviated label that is more compatible with importing the dataset into a GIS. The first part of the attribute definition is the longer label of the column that is in the second row of the Excel spreadsheet.
The Excel spreadsheet has the following information in the first row describing the spreadsheet.
GPS navigation log: Column A, vessel name, AUK, SBNMS research vessel; column B, field activity number; column C, date, UTC; column D, Julian Day, UTC; column E, study area time zone; column F, time, UTC (for Eastern Standard Time substract 5 hours); column G, latitude north, degrees and decimal minutes; column H longitude west, degrees and decimal minutes; column I, latitude north, decimal degrees; column J, longitude west, decimal degrees; column K, geographic region [abbreviations: D, degrees; H, hour; M, minute; S, second; EST, Eastern Standard Time; lat, latitude; lon, longitude; WHCMSC, USGS Woods Hole Coastal and Marine Science Center; SBNMS, Stellwagen Bank National Marine Sanctuary; UTC, coordinated universal (Greenwich Mean Time, ZULU time); GPS, satellite-based Global Positioning System receiver]
The columns of data are the same as represented in the entity and attribute detail information.
The files with the same prefix name, but the CSV extension are exported from the Excel spreadsheet, minus the first two rows of information.
The *_raw.csv files are the original $GPGGA strings off the ship. An example row from that file is:
$GPGGA,123058,4158.6481,N,7039.2771,W
The format of the columns of information are as follows:
$GPGGA, UTC time, latitude (DDMM.MMMM), latitude hemisphere, longitude (DDMM.MMMM), longitude hemisphere.
The first row in the *raw.csv file contains the filename and not the column headers.
