Data format: | Navigation information are recorded as successive lines in a comma-delimited ASCII text file, with a .glo extension. Each line of a GLO file includes the following data: the year, day of year, time, latitude, longitude, water column depth, vehicle depth, layback, and wing angle. The field for wing angle does not contain useful data. A total of 6 navigation files were collected, including: ala03000.glo ala03001.glo ala03002.glo ala03003.glo ala03004.glo ala03005.glo in format ASCII |
