Figure F7. Adopted marine paleoenvironmental classification (after Hayward et al., 1999). Oceanicity assignments are based on planktonic foraminifer abundances relative to total foraminifers (planktonic %). Planktonic abundances <5% = sheltered or restricted inner neritic; abundances >95% = open oceanic. Paleodepth assignments during Expedition 317 were primarily based on benthic foraminiferal assemblages. Calibration of bathyal subenvironments follows Hayward et al. (1999) and Crundwell et al. (1994). Note that oceanicity determinations are partially independent of water depth.
