Planktonic foraminifers from DSDP Site 586 on Leg 89 and Sites 587-594 on Leg 90, cored by the Glomar Challenger from the equator to subantarctic waters of the southwest Pacific, are recorded. Five zonal schemes were used because of latitudinal changes in faunal assemblages and these are discussed;...
