planktonic geochronology The use of planktonic organisms, e.g. globigerinid foraminiferids or microscopic algae, to provide a relative dating of sediments deposited in marine waters. Radioactive-decay methods applied to planktonic organisms may also yield an absolute date or information on palaeoclimates.
