Abstract:
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. 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. Therefore, the first 9 days (before July 5, 2020) of the cruise are excluded from the processed data set as the instrument settings were different in that time period. The processing ends on July 17, 2020, when the cruise departed from Fram Strait. The ADCP data were processed using the Ocean Surveyor Sputum Interpreter (OSSI) software developed by GEOMAR Helmholtz Centre for Ocean Research, Kiel. Ensembles with a percent good of less than 50% or containing less than 35 individual pings were excluded.
