对热带太平洋三个地区（东太平洋海隆、翁东爪哇高原和南海）的有孔虫样品进行了~（14）C年龄测定。对四种浮游生物和混合底栖生物进行了分析。对浮游物种进行多重分析的目的是评估生物扰动-丰度变化偶、生物扰动-部分溶解偶和底流再沉积造成的人为现象的重要性。目的是利用底栖生物-浮游生物年龄差作为确定过去25 000年深海通风率变化的手段。本文介绍了部分工作的结果。
14C ages were determined on samples of foraminifera separated from cores from three areas of the tropical Pacific (East Pacific Rise, Oontong Java Plateau, and South China Sea). Analyses were made on four planktonic species and on mixed benthics. The purpose of the multiple analysis on planktonic species is to assess the importance of artifacts resulting from the bioturbation-abundance change couple, from the bioturbation-partial dissolution couple and from redeposition by bottom currents. The goal is to use the benthic-planktonic age difference as a means of establishing changes in deep sea ventilation rate over the past 25,000 years. Results of a part of this work are presented in this paper.
