Figure 2. Summary of Hole 990A volcanostratigraphy and physical property measurements. Solid lines = running-average filtered data. Filter length = 5 samples (velocity) and 15 samples (density and magnetic susceptibility). Curator depth scale used; measurements on adjacent cores with overlapping depth values removed. High-pressure velocity data from Cerney and Carlson (Chap. 3, this volume), other data from Shipboard Scientific Party (1996).
