I-129, U-236 and tritium data from cruise "FARDWO-DS2 2024"

This dataset contains hydrographic and radionuclide tracer (iodine-129, uranium-236 and tritium) data for 92 discrete seawater samples collected during the FARDWO-DS2-2024 cruise. Each record is identified by its station, cast and bottle combination. The accompanying hydrographic variables include sampling position and date, bottom depth, pressure, sampling depth, in-situ and potential temperature, Conservative Temperature, Practical and Absolute Salinity, density and potential-density anomalies, and dissolved oxygen. Radionuclide variables comprise dissolved iodine-129, uranium-236 and tritium abundances, their analytical uncertainties and quality flags, the uranium-236/uranium-238 atomic ratio, and uranium-238 concentration. Tritium (3H_TU24) values are all decayed to a reference date of 01-JUL-2024. Bottle hydrographic data for station 20 were corrupted and are extrapolated from target depth and CTD sensor data at the target depths.
