Marine Isotope Stage 5e diatom assemblages in marine sediment core ANTA91-8 (-70.78 degN, 172.83 degE, Cruise ANTA91)

A new version of this dataset is now available: Chadwick, M., & Allen, C. (2021). Marine Isotope Stage 5e diatom assemblages in marine sediment core ANTA91-8 (-70.78 degN, 172.83 degE, Cruise ANTA91) - VERSION 2 (Version 2.0) [Data set].

This dataset presents the relative diatom abundances of 56 species/groups from the 132-120 ka interval in marine sediment core ANTA91-8 (-70.78 degN, 172.83 degE). This age interval corresponds to the peak of Marine Isotope Stage 5e (130-116 ka). Microscope slides were prepared using a method adapted from Scherer (1994) and 300+ diatom valves were counted for each depth sample to produce the relative percentage abundance of each diatom species/group.

This project was funded by the UK Natural Environment Research Council Grant NE/L002531/1.
