Alternatively, there may have been two periods of rapid sea level rise.
In contrast, in the Bahamas, there is evidence that sea level remained rather constant over the time interval 132 to 120 ky.
) values higher than 160 and USr ratios substantially lower than seawater are assumed to have undergone diagenetic alteration, which appears to be common in this area.
The simplest model for sea level height for terrace VII is a continuous rise between 134 and 118 ky.
The absence of ages between 132 and 120 ky in PNG could be the result of changes in the local tectonic uplift rates during that time, or erosion that disrupted the continuous record.
