CEAMARC-CASO 12kHz Bathymetry - data collected from voyage 3, 2007-2008 of the Aurora Australis

Abstract: Bathymetry data was collected using a Simrad EK60 echosounder. The sample data have been corrected for the relative locations of GPS antenna, transducers and waterline. A sound-speed value of 1500 m/s was applied when calculating depth.

The seafloor depth itself was defined firstly as the depth of the sounder-detected bottom minus 10m (contact Simrad for more information about their ... View entire text

Quality 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 SonarData Echoview software. In the process of loading raw files into Echoview 'EV' and 'evw' files are created. Setting used for processing data are preserved in ... View entire text
