Dissolved thorium isotopes from SONNE cruise SO245 (UltraPac)

This dataset contains full depth profiles of dissolved 230Th and 232Th collected on the UltraPac expedition (RV Sonne SO245 cruise) in the South Pacific Ocean in 2015-2016. The samples were collected and measured according to GEOTRACES protocols. The long-lived Th and Pa isotope data can be used to assess trace element supply and removal rates across the South Pacific.
