I-129 and U-236 data from cruise "Iceland 2024" (MFRI: B12-2024)

This dataset contains hydrographic and radionuclide tracer (iodine-129 and uranium-236) data for 30 discrete seawater samples collected during the routine Marine and Freshwater Research Institute (Iceland) MFRI B12-2024 hydrographic survey (August 2024). 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 and uranium-236 abundances, their analytical uncertainties and quality flags, the uranium-236/uranium-238 atomic ratio, and uranium-238 concentration.
