PSA-916. Inlets of the two T/C sensor pairs were soaked in distilled water before the start and 
after the end of each CTD cast. A supplementary temperature sensor was installed at the 
height of Niskin bottle about 1 m above the CTD unit in order to record water temperature at 
the time of the bottle closing. All temperature and conductivity sensors were successfully re- 
calibrated in the BSH’s calibration laboratory prior to the cruise. All devices and sensors that 
were in use are listed in Table 5.1, the Niskin bottle set-up is listed in Table 5.2. Temperatures 
are reported on the /TS-90 scale. Derived salinities refer to the Practical Salinity Scale of 1978 
(PSS-78). All respective densities have been inferred from the EOS-80 equation.
