The file will be updated as new data come available. The content is:
variable | unit | description
:--- | :--- | :---
profile no. | | number of CTD cast
niskin no. | | niskin bottle number
sample no. | | sample identifier as used on board
latitude | deg N |
longitude | deg E |
Date | UTC |
Time | UTC |
pressure | dbar | CTD pressure reading in dbar
temperature | degC | CTD temperature reading
salinity | | calculated CTD salinity
oxygen sensor | µmol/kg | Oxygen concantration as recorded by the CTD sensor. The data are calibrated with Winkler titrated samples.
chl2_raw | | flourescence from Wetlabs Fluorometer (serial # FLNTURTD-2928)
chlorophyll a | µg/L | calculated chlorophyll concentration using [calibration coefficents from Wetlabs](https://git.geomar.de/tobias-steinhoff/Poseidon-POS519/blob/master/data%20processing/docs/FLNTURTD-2928.Charsheet-1.pdf)
potential density | kg/m3 |
oxygen titrated | umol/kg | oxygen concebtration determined by Winkler titration on board
turb_raw | | turbidity data raw from Wetlabs fluorometer
NO3 | µM/L | nitrate concentration, calibration solution was too low, so some samples are off scale -> QF=3
NO2 corr. | µM/L | nitrite concentration
PO4 | µM/L| phospate concentration, calibration solution was too low, so some samples are off scale -> QF=3
SiO2 | µM/L | silicate concentration
