226Ra and 228Ra from SHEBA, Polar Star 2000 Expeditions (ASCII) [Kadko, D.]


These data are from two different cruises, one the SHEBA cruise with data from 6/27/98 - 10/17/98, and the second a Polar Star Cruise during August of 2000. This dataset contains measurements of the water column activities of the naturally occuring isotopes 226Ra and 228Ra. Because 228Ra (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. These data are in ASCII format.
