The composite depth scales presented here differ in important ways and supersede the preliminary versions completed during Leg 178. In particular, time limitations during Leg 178 prevented extensive analysis of many of the data sets, including the lithology and several of the magnetic and physical properties data sets. In contrast, the new depth scales incorporate lithologic constraints and examine a larger array of data sets, allowing us to establish which data sets provide the best correlation and which data should be avoided. For example, the composite depth scale for Site 1098 developed during Leg 178 did not rely on the magnetic susceptibility as a constraint. Here, we have shown that this data set contains many diagnostic anomalies that aid in correlating Holes 1098A, 1098B, and 1098C.
