Supplementary data:


A marine geophysical survey that used Seabeam, multi- and
single-channel seismic reflection, gravity, and magnetic profiling
was conducted in two locations along the landward slope
of the Peru Trench. This survey was conducted during the
SeaPERC cruise of the Jean Charcot in July 1986 (Bourgois et
al., 1986a; Bourgois et al., 1986b; Bourgois et al., 1987; Bourgois
et al., in press). These areas were two possible drilling locations
for ODP Leg 112, which was scheduled to begin in November
1986. The drilling transects center around latitudes of
5°30'S and 9°30'S, along multichannel seismic lines CDP-3
and CDP-2, respectively. The northern transect is located in the
Paita Zone (Fig. 1, Box 2), and the southern transect is in the
Chimbote Zone (Fig. 1, Box 6).
During Leg 112, we drilled two sites (683 and 685) in the
Chimbote area. This became the northern transect of Leg 112.
Here, we report the Seabeam data acquired during the SeaPERC
cruise. Drilling results from Sites 683 and 685, the CDP-2 multichannel
seismic record, and the Seabeam data provide a threedimensional
view of this region.
