Figure F4. Backstripped R2 eustatic estimates (Van Sickle et al., unpubl. data) for five coastal plain boreholes. Backstripping studies of Ocean View and Bethany Beach are ongoing. Heavy lines = best estimates, light lines outlining color shared areas = error bars. R2 is the second reduction of Bond and Kominz (1984) that provides a eustatic estimate (see Kominz et al., 1998, for discussion).
