Abstract:
This dataset contains Hemidiscus karstenii (Hk) and Fragilariopsis kerguelensis (Fk) relative abundances (RA in % of the total diatom assemblages) and absolute abundances (AA in millions of valve per gram of dry sediment) versus depth and age.Hk and Fk biometry versus depth and age are also included. For each depth, mean length results from measurements of 100 different and complete valves of both Hk and Fk on which within-sample standard deviations were calculated.
