Figure 10. Bathymetric map of the NESCA area of Escanaba Trough showing the location of the Southwest Hill, Central Hill, on-axis volcanic rocks, sulfide deposits (black), and active vent sites. Location of the proposed Sites ET1-5 and ET7 are shown. The location of faults is constrained by the seismic profiles, camera and submersibles scarps. Modified from Zeirenberg et al. (1994).
