Figure 3. Decimeter- to meter-scale alternations of light-colored ooze/chalk/limestone and dark-colored marl/marlstone along the Bahamas Transect are interpreted as the record of high-frequency sea-level fluctuations. The neritic portion is judged to have been deposited during sea-level highstands, whereas the marls are lowstand and/or transgressive deposits (modified from Bernet, 2000).
