CEAMARC-CASO 12kHz Bathymetry - data collected from voyage 3, 2007-2008 of the Aurora Australis
Progress Code: completed Statement: Raw data conists of 'bot', 'idx' and 'raw' files. The bot file contains information on a sounder detected bottom, the idx file is an index file and the raw file contains the ping data itself. These files are loadable/readable with Son...
