CTD and routinely analyzed biogeochemical parameters in samples collected during R/V Mirai MR23-06C cruise

This dataset includes the profiles of CTD, dissolved oxygen, chlorophyll-a fluorescence, beam attenuation coefficient), turbidity, nitrate, and photosynthetically available radiation at the same depths where discrete water samples were collected as the in-situ-sensor-measured data. In addition, salinity, oxygen, major nutrients, dissolved inorganic carbon, total-Alkalinity, and chlorophyll-a concentration (bulk and size-fractionated) were measured in water samples collected using a Niskin-bottle rosette at selected depths.
