    Description: 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.

    Description: In this dataset we present a global compilation of over 1000 sedimentary records of 230Th from across the global ocean at two time slices, the Late Holocene (0-5000 years ago, or 0-5 ka) and the Last Glacial Maximum (18.5-23.5 ka). Data have been screened for age control, errors, and lithogenic corrections. Overall quality levels were computed by summing each record's scores on the individual criteria. A record is optimal if it is based on a chronology that is constrained by δ18O or 14C and it provides both the raw nuclide concentrations and the associated errors. About one quarter of the records in the database achieved this highest quality level. The large majority of the records in the database are good, passing two of the three criteria, while the remaining quarter are of fair or poor quality.
