The lithostratigraphic units at each of the Leg 190 drill sites were correlated with two-dimensional seismic reflection data collected in 1987 (Moore et al., 1990, 1991) and a three-dimensional seismic reflection data set collected in 1997 (Bangs et al., 1999; Moore et al., 1999). The 1987 lines were stacked and depth migrated using velocities models from two-ship wide-angle refraction data also collected in 1987 (Stoffa et al., 1992). Initial depth sections of the 3-D lines were made during Leg 190 based on these depth models. Refined depth conversions were made using the total depths of the drilled holes. Physical properties and logging data were used to help correlate the site lithostratigraphy with the seismic data. Because the depth sections are not well constrained, the depth correlations with lithostratigraphic units should be considered preliminary and subject to change when better depth sections are constructed.
