This raw data of physical oceanography was acquired during research cruise EMB304 of 'RV Elisabeth Mann Borgese' from October 25th to November 02nd 2022. Thereby data was measured by a Seabird SBE911+ as part of a CTD-Rosette. Default onboard CTD system of EMB consists of the SBE9 with 2x SBE43 for oxygen, 2 SBE3 temperature sensors, PAR sensor, altimeter, fluorometer, turbidity meter and a down facing camera to estimate distance to the bottom. The CTD is operated with active heave compensation. Water is sampled with 13 free flow water bottles holding 10l each.
