Enhanced scavenging of super(231)Pa relative to super(230)Th in the South Atlantic south of the Polar Front: Implications for the use of the super(231)Pa/ super(230)Th ratio as a paleoproductivity proxy

The fractionation of super(230)Th and super(231)Pa was investigated throughout the Atlantic sector of the Southern Ocean. Published scavenging models generally assume that the super(231)Pa/ super(230)Th ratio of surface sediments is primarily determined by the mass flux of particles. This relationsh...
