Several planktonic foraminifer datum points were revised by Resig et al. (in press). Similarly, slight corrections for several magnetic chron and subchron boundaries have also been made (G. Frost, pers. comm., 2000). Moreover, Lackschewitz et al. (in press) measured 40Ar/39Ar ages for fallout tephra layers and volcaniclastic deposits in the sedimentary successions at Sites 1109, 1115, and 1118. Seismic correlation between Sites 1109 and 1118 were made by Goodlife et al. (this volume).
The sedimentation rates were recalculated based on the revised and newly obtained age assignments mentioned above at Sites 1109, 1115, and 1118 (Figs. F1, F2, F3, respectively). Based on these calculations, sedimentation curves were correlated between sites (Fig. F4).
Testa et al. (this volume) found several radiolarian datum levels from Holes 1108B, 1110A, 1111A, 1112A, and 1115B. Newly obtained maximum ages for select Quaternary samples from Sites 1108, 1110-1112, and 1115 are listed in Table T1. For each sample, the actual age may be equal to or younger than the age of the radiolarian zone indicated.
