Southern Ocean Primary Productivity Changes during Middle Eocene to Early Oligocene: Inferences from Benthic Foraminifera: Datasets and Supplementary Materials
These datasets contain raw data on benthic foraminiferal abundance and stable isotopes used for statistical analysis. Results suggest the change in the past productivity with time. The interval from the late Eocene to the early Oligocene marked increased productivity with a maximum gain at the Oligocene-Eocene boundary. During Eocene, the proto-Antarctic Circumpolar Current initiated at a deeper depth and may have enhanced productivity.
