Sediment depth is given in mbsf. Abundance estimates as follows: A = abundant, C = common, F = few, R = rare, - = not found. Unable to delineate zones because of sparse nannofossils and lack of strati
Species abundance: D = dominant (>50 %), A = abundant (10-50 %), C = common (1-10 %), F = few (0.1-1 %), R = rare (<0.1 %), - = not present, cf = confer, ? = questioinable...
Seven Ocean Drilling Program (ODP) sites recovered during ODP Leg 177 in the Atlantic sector of the Southern Ocean were analyzed to study the Pleistocene calcareous nannofossil...
