Abstract:

This dataset contains full depth profiles of particulate 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.
