摘要：

A high-quality deltaO-18 record has been obtained from a deep sea core in the Somali Basin in a water depth of 4020 m, well below the foraminiferal lysocline, by analyzing bulk sediment instead of picked foraminifera. In some areas this may be a valuable tool for extending the applicability of the deltaO-18 stratigraphy, for obtaining data by a less labor-intensive procedure, and for conserving valuable core material. Additionally, we draw attention to the need for more data on deltaC-13 in bulk carbonate if we are to fully utilize the ocean deltaC-13 record either in relation to long-term global carbon budget, or in relation to changes in carbon cycling in the ocean and its effect on atmospheric pCO2.
