MATERIALS AND METHODS

Multisenor track and spectral reflectance data collected from Site 1209 (Holes 1209A, 1209B, and 1209C), Site 1210 (Holes 1210A and 1210B), and Site 1211 (Holes 1211A, 1211B, and 1211C) were used to redetermine depth offsets and revise the shipboard composite sections. Magnetic susceptibility was the primary parameter used for core-to-core correlation, and we shifted the individual cores vertically without permitting expansion or contraction of the relative depth scale within any core. This is an analog to the shipboard software Splicer. Next, we assembled a new single spliced record of the revised composite depth section for Sites 1209, 1210, and 1211. Intervals having significant disturbance or distortion were avoided. For the construction of the revised records, we left the tie points between holes at the original (shipboard) position where possible. Changes in the position of tie points in the new revised spliced record have been highlighted as bold letters in the splice tables of each site (see "Results—New Revised Composite Depth," below). Cores outside the revised composite splice have been stretched or squeezed using the time-series analysis program AnalySeries (Paillard et al., 1996) to conform to the overall rmcd depth scale and to align samples from outside the shipboard and revised splices. This enables samples taken already to be placed into the new revised composite depth scale.
