This paper is a comparative study of the variation in 10Be content of different late Cenozoic sedimentary environments recovered during ODP Leg 117. The Oman Margin site, Hole 728A, with overlying high-productivity cells, the pelagic Owen Ridge site, Hole 722A, and the Indus Fan site, Hole 720A, each display a specific 10Be distribution with time. Differences in scavenging intensity and upwelling in the water column, must account for the variations in the initial 10Be input into the sediments from Holes 728A and 722A, whereas differences in sediment character and sedimentation rate can explain the variances between Holes 722A, 728A, and 720A.
