The attribute label is the abbreviated label in row 3 of the Excel file 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 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 time (Greenwich Mean Time, ZULU time); GPS, satellite-based Global Positioning System receiver]
The 11 columns of data are the same as those represented in the entity and attribute detailed description.
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. The first row in the *raw.csv 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.
