Phase relationship between sea level and abrupt climate change
15 pages, 10 figures, 2 tables.-- Printed version published Direct traces of past sea levels are based on the elevation of old coral reefs at times of sea level highstands. However, these measurements are discontinuous and cannot be easily correlated with climate records from ice cores. In this stud...
