Figure F6. Amplitude and phase of observed basement pressure variations resulting from diurnal and semidiurnal tidal loading from the CORK in Hole 395A, as well as Holes 1024C and 1025C on the east flank of the Juan de Fuca Ridge (after Davis et al., 2000). The data fit well to smooth curves remarkably similar to predictions of the conceptual model for tidally driven lateral flow in a partially buried permeable basement, as described in more detail by Davis et al. (2000).
