All frequencies were logged continuously for the extent of the voyage, except for a period of time between 26/03/2022 05:00 and 29/03/2022 11:05 UTC when all data recording was mandated to be suspended. The 70kHz was occasionally set to passive while in shallow water to limit interference with the EM710 multibeam.Data are stored in *.raw, *.bot and *.idx format at CSIRO.
