The effects on calcite dissolution of both volcanic ash-fall and oceanic circulation were evaluated in lower bathyal sediments from the last 550 ka record of the core MD 97-2114, recovered on the northern slope of the Chatham Rise ( east of New Zealand, SW Pacific Ocean). This area was involved, dur...
