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...

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 the template 'Bathy_template_200708030.EV'. The Echoview software is used to export a time position series of depth data. Exported data is in comma delimited ASCII format and files contain information about the seafloor-exclusion line created during analysis of the CEAMARC-CASO hydroacoustic data (collected with a Simrad EK60 echosounder system). This line was exported from the 12 kHz 'post-processed' echogram, generating CSV files with the following headings: Ping_date (dd/mm/yyyy, UTC) Ping_time (hh:mm:ss, UTC) Ping_milliseconds (ms, UTC) Latitude (of the ping in decimal degrees, 999 if unknown) Longitude (of the ping in decimal degrees, 999 if unknown) Position_status (quality of the GPS fix-interpolation at the ping time, where 1=good, 3=uncertain, 4=unknown) Depth (of the surface-exclusion line in metres) Line_status (certainty of the line depth, where 0=bad, 1=good, 2=unverified, 3=no line) Ping_status (a user-specified status for each ping, ranging from 1-11) Altitude (in m, -9999.99 if unknown - not sure what this is) GPS_UTC_time (hh:mm:ss, -1 if unknown) 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 bottom-detection algorithm), and then modified manually where necessary to ensure that the line followed the seafloor as perceived by eye from the ...
