the central Pacific correlate well with a late Tertiary sea level curve
based on biostratigraphic ages and {sup 87}Sr/{sup 86}Sr
chronostratigraphy for core from Enewetak Atoll in the northern
Marshall Islands. Further drilling of the archipelagic aprons adjacent
to atolls will improve the sea level history that may be inferred from
atoll stratigraphy.

Abstract: Past sea levels can be derived from any atoll subsurface
sediments deposited at or near sea level by determining the ages of
deposition and correcting the present depths to the sediments for
subsidence of the underlying edifice since the times of deposition. A
sea level curve constructed by this method consists of discontinuous
segments, each corresponding to a period of rising relative sea level
and deposition of a discrete sedimentary package. Discontinuities in
the sea level curve derived by this method correspond to relative sea
level falls and stratigraphic hiatuses in the atoll subsurface. During
intervals of relative sea level fall an atoll emerges to become a high
limestone island. Sea level may fluctuate several times during a period
of atoll emergence to become a high limestone island. Sea level may
fluctuate several times during a period of atoll emergence without
depositing sediments on top of the atoll. Furthermore, subaerial
erosion may remove a substantial part of the depositional record of
previous sea level fluctuations. For these reasons the authors must
look to the adjacent basins to complement the incomplete record of sea
level change recorded beneath atolls. During lowstands of sea level,
faunas originally deposited near sea level on an atoll may be eroded
and redeposited as turbidites in deep adjacent basins. Three such
turbidites penetrated during deep-sea drilling at Sites 462 and 315 in
