Figure F4. A. Time-migrated MCS line Meg-10 sections modified from Canales et al. (2004) showing the cross-strike structure of the core complex. Reflector D is interpreted to coincide with top of unaltered peridotite. B. Gathers for common midpoints (CMPs) 21502180 are plotted with move-out correction for 1.5 km/s (left) and 2.25 km/s (right). C. Location of Site AMFW-01A is indicated in expanded view of the domal portion of Meg-10. Depth to reflector D (Based on 5 km/s interval velocity determined by Canales et al., 2004) is ~500 m, and total penetration will go as far as possible beyond this. Possible locations for alternate sites are indicated by red arrows (proposed Sites Alt AMFW-02A, 03A, and 04A). As many as three single-bit penetrations might be attempted across the dome along seismic Line Meg-10, between CMPs 1800 and 2600 (exact locations and number of sites to be determined by subsea camera survey, time available for alternate site occupation, and scientific objectives addressed during preceding occupations).
