Layering. What does it mean?' Robert Ginsburg made this passing comment in the mid-1960s when the author was looking at a core sequence from Biscayne Bay, Florida. The core was a burrowed carbonate wackestone with a Hurricane Betsy storm layer at the top. It was a timely question as 'Layering -What does it mean?' has been asked many times since then. A few important answers have emerged -but there are still some serious challenges ahead. Understanding layering is more than just looking at the

Together, these provide the critical tools to reconstruct paleoenvironmental setting, define depositional processes and determine the spectrum of energy levels operating in the system.
