Feeding selectivity and rapid particle processing by deep-sea megafaunal deposit feeders : A 234Th tracer approach

To explore the selectivity and rates of megafaunal deposit feeding, Miller et al compared excess 234Th activities in the gut contents of deposit feeders from Santa Catalina Basin (SCB) and the Hawaiian slope to the activity of surface sediments and, in SCB, to material from sediment traps moored abo...

Zusammenfassung:	To explore the selectivity and rates of megafaunal deposit feeding, Miller et al compared excess 234Th activities in the gut contents of deposit feeders from Santa Catalina Basin (SCB) and the Hawaiian slope to the activity of surface sediments and, in SCB, to material from sediment traps moored about 150 meters above the seafloor.
