Notes on the non-GEOSECS 210Pb dataset

The 210Pb and 226Ra data contained on this and related web pages were collated as part of a continuing project to investigate the distribution of natural Pb isotopes in the oceans prior to anthropogenic perturbation.

Together with the GEOSECS 210Pb dataset, this dataset should contain all extant open-ocean 210Pb data. If you know of existing 210Pb data not included in this dataset please contact me at

The dataset; stat. = latitudes and longitudes are decimal; north and east are positive; depths are in metres; 210Pb measurements are in dpm/100kg.
