Figure F1. All Site 1224 drilling took place at proposed Site H2O-5, which is 1.48 km northeast of the junction box at the Hawaii-2 Observatory (H2O). Circles at 1, 2, and 3 km radius from the junction box are shown. The locations of the single-channel seismic lines acquired during the site survey cruise in 1997 are shown as dashed lines. The solid line between them is the approach line taken by the JOIDES Resolution on 26 December 2001. Echo sounder recordings (Fig. F2) were made along this line. The symbols labeled H2O-1, H2O-2, H2O-3, and H2O-4 show alternate drilling sites that were discussed in the Leg 200 Scientific Prospectus.
