AbstractFecal pellet fluxes were determined using a series of multireplicate traps set at 35, 65, 150, 500, 750 and 1500 m in the northeast Pacific.Fecal pellets appear to be important contributors to total carbon fluxes. In near-surface waters (35-150 m), pellet fluxes ranged from 2-3 × 105 pellets m-2 day-1. Minimum pellet fluxes were observed at 500m(̃0.4× 105 pellets m-2day-1). In contrast, the 1500 m pellet flux value increased to approximately 0.8 × 105 pellets m-2 day-1 relative to the 500 m depth, and is probably the result of in situ repackaging. Analyses of pellet content suggest multiple sources of "large" particle input throughout the water column. The implications of this phenomenon are discussed in terms of the detrital rain and ladder of migration theories. © 1981 IRL Press Limited.
