The 75kHz and the 38kHz Teledyne Ocean Surveyor ADCPs built into the hull of RV MERIAN were operated continuously during MSM93 when in waters where diplomatic clearances existed. The data recording was restarted more than once a day to ease subsequent data processing. In the beginning of the cruise various different settings were tried out (see auxiliary information in this data set and information in cruise report). In particular, the 75kHz ADCP was programmed to record vertical bins of 4m size. The goal was to get an increased vertical resolution. However, this was switched back to 8m bins on July 5 in order to achieve a better signal to noise ratio.
