Figure F1. A. Predicted topography of the northwest Pacific (Smith and Sandwell, 1997) and selected physiographic features. Circles locate Site 1149 (~100 km east of the Izu-Bonin Trench) and DSDP Sites 303 and 304. B. Circles indicate Site 1149 hole positions. The bold black line indicates the track of the ~50-km-long single-channel seismic (SCS) survey conducted during Leg 185 (JOIDES Resolution, Leg 185 SCS lines 1, 2, and 3). This SCS data is presented in Fig. F4.
The bold red line indicates the portion of SCS data displayed in Fig. F2. The thin black line indicates a segment of multichannel seismic (MCS) line 39 from the regional survey of C2005.
