Near-Realtime Processing of CTD Data

All CTD data have been recorded at an original resolution of 24 Hz. Data have been checked
and pre-processed during the cruise using the SeaBird SBE Data Processing software, version
7.26.7.129. The preliminary data taken from the downcast of each CTD profile were binned at
1 dbar resolution and sent on a daily basis during the cruise in near-real-time to the Maritime
Data Centre at BSH, Hamburg, Germany and there were uploaded to the CrossDataPortal
(https://cdp.srx.bsh.de), the open data portal of BSH, from where the data are available to the
public. In total, near-realtime data for 97 CTD profiles were submitted and published during the
Cruise.

Pre-processing showed a better performance of the secondary temperature/conductivity sensor
 pack (TC2) for most of the cruise. CTD data of profiles #037/GN026A and #038/GN027
showed unusual peaks/signals after binning, which were not obvious in the initial raw data
