228Ra is strongly enriched in shelf waters and its half-life (5.8 years) is well suited to study the fate of shelf-derived water in the central Arctic. During PS78 (TRANSARC I) we studied the distribution of 228Ra in surface waters of the central Arctic to investigate how this 228Ra signal is transp...
