refined age constraints from magnetostratigraphy indicate that since the Brunhes/Matuyama boundary (0.78 Mya) only three sea level highstands have flooded this platform. The reefal-skeletal-oolitic-peloidal facies sequence, probably representing deposition during fourth order highstands show lateral facies changes and perhaps regional climatic influences. This skeletal to nonskeletal transition is common in other Bahamian platform records, and appears to be youngest near the edges of the platform. Estimates of sea level during the Matuyama show that it reached within about 10m below present sea level. During the Brunhes at least one highstand came to 6-7m of present sea level. The uppermost part of a core containing beach facies is now about 6m above sea level and is thought to represent the 0.13 Mya sea level event.
