Abstract
Here we outline a new, pragmatic methodology to derive relative sea-level estimates from central Red Sea oxygen isotope
records based on a previously published model. In this paper, the methodology is described in detail, and it is shown that sea-
level change is the dominant factor responsible for the recorded variability in Red Sea d18O (PDB) for sea level changes greater
than 12 m. Variables such as temperature or net evaporation are shown to have relatively small effects on the oxygen isotope
record. The modelled d18O (PDB) to sea level relationship is given in terms of a fifth order polynomial which may be used to
describe relative sea level from central Red Sea oxygen isotope records. We show how established sea level records from fossil
reef terraces for the last 20 kyr are successfully simulated from central Red Sea oxygen isotope records. We also examine the
spatial variability of d18O (PDB) in the basin over the last 13 kyr.
