Sediment accumulation rates in the southwestern Pacific Basin and Aitutaki Passage

Metal accumulation rates in sediments from the Southwestern Pacific Basin.

“…228KG-251 KG are probably the result of in creased erosion by the Antarctic Bottom Water in these areas as previously shown by Schmitz et al (1986). A clear increase in the biogenic opal ac cumulation rate is also observed at Stn.…”

“…There also seemed to be a threshold sedi ment accumulation rate below which manganese nodules form in abundance. More recently, we have obtained sedimentation rates on 11 sediment cores from the Southwestern Pacific Basin which confirmed this idea by establishing a 15-fold or more decrease in sedimentation rate across the basin (Schmitz et al, 1986). In addition, the ac cretion rates and element accumulation rates of seven manganese nodules from the Southwestern Pacific Basin have been determined (Mangini et al, 1990).…”

“…From a knowledge of the sediment accumula tion rate and density (Schmitz et al, 1986) and the average element content of the sediment (Meylan et al, 1982;Stoffers et al, 1985), it is possible to compute the element accumulation rate for the sediment by simple multiplication (McMurtry et al, 1981;Thomson et al, 1984). Table 2 repre sents the first compilation of such rates for the Southwestern Pacific Basin.…”

“…We types are given by Meylan et al (1982) and Stoffers et al (1985). Accounts of the analytical and dating methods have previously been reported by Stoffers et al (1985) and Schmitz et al (1986). Figure 1 shows the locations of the sample sta tions.…”
