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 75 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 temperature, conductivity, and depth measurements of the water column. Additional information regarding this field activity is available from https://cmgds.marine.usgs.gov/fan_info.php?fa=2015-062-FA.
Purpose:
These 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.

Data_Quality_Information:
Logical_Consistency_Report:
The navigation was downloaded each day of the cruise and is available in the original GPGGA format as well as reformatted for easier use. The reformatted version of the navigation excludes the transit navigation. The filenames indicate the cruise and day of navigation. The reformatted filenames are in the format AUK2015062_station_nav_log_XXXX_UTC where XXXX is the day of navigation (for example 04NOV2015). The filename suffix is either XLSX or CSV. The original GPGGA navigation filenames are in the format AUK2015062_XXXX_UTC_nav_raw.csv where XXXX is the day of navigation (for example 04nov2015).
Completeness_Report:
The raw navigation files (with the $GPGGA string) represent all the navigation acquired on the cruise. These files are the orignal files handed over to the scientist. The reformatted navigation files have removed the transit navigation to and from port to the study area. Of note - both the original navigation and the reformatted navigation have duplicate navigation fixes (same time and fix).
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 one 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. $GPGGA is a National Marine Electronics Association (NMEA) GPS string or sentence that indicates Global Positioning System fix data.
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 each file describes the file.

Process_Step:
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 (version 2013) 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‚Äč)*-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. These reformatted files omit the transit navigation to and from the port to the study area.

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 Daylight Time subtract 4 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; EDT, Eastern Daylight 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 ranges of numeric values are based on the processed navigation files which omit the transit navigation.
The *_raw.csv files are the original $GPGGA strings off the ship. 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 each file describes the file.
