- Abstract
Numbers of fecal pellets in marine snow varied with depth and kind of aggregates ranging from 31-353 000 fecal pellets l-1 marine snow. Fecal pellets were enriched in marine snow by a factor ranging from 0.3-3800. Small fecal pellets (m<105 μm3) contributed up to 68% of the total fecal pellet volume in marine snow. Fecal pellets are a major source of carbon in marine snow (up to 37%) and they are effectively scavenged especially by large (>1m) amorphous aggregates. Besides low sinking velocities, resuspension and reingestion, trapping of fecal pellets by marine-snow is an efficient mechanism to keep fecal pellet-derived carbon confined to the upper layers of stratified water columns. -from Authors
