The production of composite depths and creation of spliced sections has been described in detail elsewhere (e.g., Hagelberg et al., 1992; Curry, Shackleton, Richter, et al., 1995; Jansen, Raymo, Blum, et al., 1996; Gersonde, Hodell, Blum, et al., 1999; Wang, Prell, Blum, et al., 2000). The data generally available were magnetic susceptibility (MS), gamma-ray attenuation (GRA) bulk density, natural gamma-ray activity, and compressional-wave (P-wave) velocity, all from the whole-core multisensor track (MST) logger, and the color of the split core measured using a handheld Minolta color scanner. Three of the physical properties (MS, GRA density, and P-wave velocity) were measured at 2-cm intervals; the fourth (natural gamma-ray activity) at 15-cm intervals. The interval between Minolta color-scanner measurements on the split core was usually 5 cm. The program SPLICER (version 2.1) was used to generate the composite depth scales and produce the spliced sections. This program allows comparison of data from several holes by overlaying and moving them vertically to optimize correlation. Cumulative optimal offset depths of cores are recorded in an "affine" table (the essence of which is extracted as Tables T1 and T2 for Sites 1095 and 1096, respectively), which may then be applied to each core to locate it on a common composite depth scale (meters composite depth [mcd]). The composite depth scale then forms the basis of selection of optimal "spliced" sections using most of the cores from each hole. Sections are selected to avoid core ends, unrecovered core, gas voids, disturbed core, presampled core (e.g., for interstitial water samples), and so forth. The correlated points that define the sections comprising the splice are tabulated in Tables T3 and T4 for Sites 1095 and 1096, respectively. The MS values for all three holes and for the spliced sections are plotted against depth to 90 mcd for Site 1095 in Figure F1 and to 270 mcd for Site 1096 in Figure F2. The spliced MS curve is color-coded to show the origin of each section used.
Tables T1, T2, T3, and T4 do not include the lower sedimentary succession at each site, which was only sampled in a single hole. Composite depths for these deeper cores are conventionally determined by applying to them the same offset as was attributed to the deepest core that had a counterpart core in another hole. Similarly, usually because of intervening poor recovery, some multiple-cored intervals cannot be tied unambiguously to those above them; here also, the offsets are kept the same as for the overlying core, and the splice below is "floating." In Tables T3 and T4, the uncorrelated core connections are labeled as "append" and the unlisted deeper cores are all similarly appended to the overlying spliced sections.
