LSRs were calculated for each site and plotted with visual best-fit lines in Figure F5. Sedimentation rates for Hole 1067A are based on nine nannofossil age estimates (Table T2). Sedimentation rates vary from ~5.5-14.4 m/m.y., with a possible hiatus during the CP10 T. orthostylus Zone. Hole 1068A LSRs are based on six nannofossil age estimates (Table T4) and range from 20 to a low of 2.6 m/m.y. during the CP10 T. orthostylus Zone. Six Eocene nannofossil age estimates (Table T6) were used to calculate LSRs for Hole 1069A. Rates vary from 3.0 to 30.0 m/m.y. The CP10/CP11 boundary is constrained only to a broad 7-m interval because of poor recovery (Shipboard Scientific Party, 1998c) in Core 173-1069A-5R (~22% recovery), making it difficult to determine if low sedimentation also prevailed during the T. orthostylus Zone (CP10) at Hole 1069A. Hole 900A LSRs are based on eight nannofossil age estimates and range from 3.8 to 28.6 m/m.y. A condensed section/hiatus during the D. kuepperi CP12a Subzone is based on the co-first occurrence of R. inflata and D. sublodoensis. These events should occur 1.2 m.y. apart, although this boundary is broadly constrained to a 7.5-m interval. Other sites studied on the IAP have high sedimentation rates through this interval, and erosion at Site 900, which sits atop a structural high, may explain the difference in sedimentation pattern at Site 900. Sedimentation rates vary from 4.0 to 25.8 m/m.y. at Hole 398D. Site 398 is in close proximity to the Vigo Seamount, and sediments were deposited above the CCD, contributing to differences in sedimentation patterns compared to other IAP sites. Nannofossil age estimates (Fig. F3) are taken from Berggren et al. (1995).
