HLY-02-03 226Ra and 228Ra Data (ASCII). Version 1.0

This data set contains measurements of the water column activities of the naturally occuring isotopes 226 Ra and 228 Ra. Because 228 Ra (T1/2= 5.77y) is derived through input from shelf sediments, it is an unambiguous marker of water that has been in contact with shelves. Its relative distribution in the shelf and basin water is therefore very valuable in assessing the degree of shelf-basin interaction.
