Figure F2. A. Schematic line drawing of the crustal structure across Hydrate Ridge based on depth-converted migrated seismic reflection data (from Westbrook et al., 1994). Interpretation is based on Line 9 from the 1989 ODP site survey (MacKay et al., 1992), along which ODP Site 892 was located. On the scale shown here, primary structural features are the same as those along Line 2, which is shown in B. B. Line 2 from the 1989 ODP site survey showing primary structural features of the deformation front and the location of data shown in Figure F5.
