©2026 Biological and Chemical Oceanography Data Management Office.We compiled a compilation of dissolved thorium (230Th and 232Th) and protactinium (231Pa) data measured by mass spectrometry, spanning from times preceding the GEOTRACES program until 2024. The dataset is available for model validation and data-model comparisons.

These numbers come from web analytics and reflect real user activity on the site. They reliably show dataset usage and are mostly free of bot traffic.
These data were collected from a variety of different publications and methods. The shared features of these datasets is that all samples reflect dissolved (e.g. filtered) samples, though the filter types and pore sizes varied from study to study. Treatment and sample preparation varied from study to study as well. None of the data in this compilation represents original measurements.
