Figure F9. Subsidence histories for (A) nonequatorial Leg 199 sites (1215, 1217, and 1221) and (B) equatorial Leg 199 sites (1218, 1219, and 1220). Carbonate compensation depth (CCD) based on presence/absence of carbonate, from shipboard observations (from Shipboard Scientific Party, 2002). See Lyle et al. (this volume) for an updated study of the Eocene CCD, and see Coxall et al. (2005) for a more detailed study of the Eocene–Oligocene transition.
