|a Studies from tectonically active coasts on New Guinea and Barbados have suggested
that sea level at;80 ka was significantly lower than present, whereas data from the Atlantic
and Pacific coasts of North America indicate an;80 ka sea level close to that of the present.
We determined ages of corals from a shallow submerged reef off the Florida Keys and an
emergent marine deposit on Bermuda. Both localities are on tectonically stable platforms
distant from plate boundaries. Uranium-series ages show that corals at both localities grew
during the ;80 ka sea-level highstand, and geologic data show that sea level at that time
was no lower than 7–9 m below present (Florida) and may have been 1–2 m above present
(Bermuda). The ice-volume discrepancy of the 80 ka sea-level estimates is greater than the
volume of the Greenland or West Antarctic ice sheets. Comparison of our ages with highlatitude
insolation values indicates that the sea-level stand near the present at ;80 ka
could have been orbitally forced. |
