Notes on the GEOSECS 226Ra 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.

If you have comments or suggestions, please contact me at gideonh@earth.ox.ac.uk

The dataset; stat. = GEOSECS station number; latitudes and longitudes are decimal; north and east are positive; depths are in metres; 226Ra measurements are in dpm/100kg.
