Site U1462, Figure F20. Optical and SEM photomicrographs of dominant benthic foraminiferal species and assemblages at Site U1462 with paleodepth based on planktonic/benthic ratio (%P) and bathymetric zone interpretation. Assemblage bathymetric zones were smoothed to
generate a synthesis, resulting in slight differences from hole summary data. For raw bathymetric zonation see Table T11.
