Figure F7. All drilling at the Hawaii-2 Observatory (H2O) took place at Site 1224 (proposed Site H2O-5), which is 1.48 km northeast of the junction box at the H2O. Alternate drilling sites (H2O-1 through H2O-4) that were discussed in the Leg 200 Prospectus are also shown (circles with crosses). Circles are drawn at 1-, 2-, and 3-km radius from the junction box. Also shown are the location of the single-channel seismic lines acquired during the site survey cruise in 1997 (dashed lines) and the track line taken by the JOIDES Resolution on 26 December 2001 (solid line). Echo sounder recordings were made along this line.
