One CTD was mounted on a stainless-steel rosette and was connected to the following sensors: Pressure (Digiquartz with TC), two temperature sensors (ITS90 °C), two conductivity sensors, oxygen (SBE43), PAR (Biospherical Licor Chelsea sensor), fluorometer (Wet Labs ECO-AFL/FL), turbidity (Wet Labs ECO-NTU) and an altimeter. The second CTD was mounted on a titanium rosette used for trace metal clean collection of water samples, and was connected to the following sensors: Pressure (Digiquartz with TC), two temperature sensors (ITS90 °C), two conductivity sensors, two oxygen sensors (SBE43), transmissometer (Wet Labs C-Star), turbidity (OBS Seapoint) and an altimeter. The oxygen data were calibrated against discrete water samples analysed using the Winkler method, other sensor data used factory calibrations. 157.85 -81.0 -2.5 0.00526 -130.54242004197621 -1.2097642380025395 2023-04-15T12:54:00 2023-05-26T22:29:44 4 CC-BY-4.0 Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/ Station label | Station | cast | Profile ID | Niskin no. | Bottle number | Bottle | Sample code/label | Sample label | Pressure, water | Press | Temperature, water | Temp | practical | Salinity | Sal | Oxygen | O2 | Density, potential | Dens pot | Density, sigma, in situ | Sigma in situ | Transmission of light | Transmission | Turbidity | Fluorescence, chlorophyll | F chl | Radiation, photosynthetically active | PAR | Oxygen bottle | Cast number | Cast | Turbidity (Nephelometric turbidity unit) | Nitrate | [NO3]- | Attenuation, optical beam transmission | Attenuation CTD data Equatorial pacific ocean Pacific Ocean geomar geomarPhysicalOceanography param102005 param134207 param162278 param16497 param19345 param2137 param28126 param28739 param4875 param52477 param530811 param6390 param715 param716 param717 param790 param80103 param80105 param87498 pi43597 pi86099 author10110 author32921 author43597 author86099 geocode1599 geocode1600 geocode1601 inst20147 license21 term242 term39419 term48770 term49953 term68811
