Site survey data Search| Backstripping is a proven method for
extracting amplitudes of global sea level from passive margin
records (e.g., Watts and Steckler, 1979). One-dimensional
backstripping is a technique that progressively removes the
effects of sediment loading (including the effects of
compaction) and paleowater depth from basin subsidence. By
modeling thermal subsidence on a passive margin, the tectonic
portion of subsidence can be assessed and a eustatic estimate
obtained (Kominz et al., 1998, 2008; Van Sickel et al., 2004).
Backstripping requires knowing relatively precise ages,
paleodepths, and porosities of sediments, and each of these
criteria are best obtained from borehole transects. Such
transects also allow application of two-dimensional
backstripping techniques that account for lithospheric flexural
effects, increasing the precision of the eustatic estimates
(Steckler et al., 1999; Kominz and Pekar, 2001). The eustatic
component
