The individual coral-based estimates of RSL (blue)
have an attached error bar that depends upon the coral species. The estimates
denoted by the short error bars are derived from the Acropora palmata species,
which provide the tightest constraints upon relative sea level as this species
is found to live within approximately 5 m of sea level in the modern ecology.
The estimates denoted by the longer error bars are derived either from the
Montastrea annularis species of coral (error bars of intermediate 20 m length)
or from further species that are found over a wide range of depths with respect
to sea level (longest error bars). These additional data are most useful in
providing a lower bound for the sea level depression. The data denoted by the
coloured crosses are from the ice-equivalent eustatic sea level reconstruction
of Lambeck and Chappell (2001) for Barbados (cyan),
Tahiti (grey), Huon (black), Bonaparte Gulf (orange) and Sunda Shelf (magenta).
