Alternatively, there may have been two periods of rapid sea level rise.

) 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.
