A detailed oxygen-isotope record and planktonic foraminiferal biostratigraphy are used to construct a chronostratigraphic framework for Site 619, Pigmy Basin, on the Louisiana continental slope. Within this framework, sediments accumulated in Pigmy Basin at a fairly constant rate over the last 105,000 yr. The oxygen-isotope record shows evidence for periods of freshwater run-off at times other than glacial terminations. Increased carbonate contents are also associated with these events
