Full description

This record describes the acoustic data collected using the EM300 multibeam echosounder and the ES60 single beam echosounder during the NORFANZ voyage on the Norfolk Ridge and Lord Howe Rise in the Tasman Sea between Australia and New Zealand, in May-June 2003. Fourteen seamount and slope sites were surveyed using the EM300 multibeam echosounder, 10 on the Norfolk Ridge and 4 on the Lord Howe Rise. There is a total of 4 gigabytes of raw EM300 data. Sound velocity profiles were processed to make TIFF images of backscatter (bs - grey scale), digital terrain model (dtm - sun illuminated colored bathymetry) , and elevation model (ele - very dark images) for each of the 14 sites. Each tiff file has an associated TIFF world files (.tfw) for a mercator 41 degree projection with origin at 100 degrees east. ES60 data for the voyage is stored in a local directory. There are 666 MB of data in EK5 format, made up of 134 files of 5MB each.
