Marine Isotope Stage 5e diatom assemblages in marine sediment core ANTA91-8 (-70.78 degN, 172.83 degE, Cruise ANTA91) - VERSION 2

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. 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.

The age model for this dataset has been updated, with new tiepoints between the sediment core magnetic susceptibility and the LR04 benthic delta-O-18 stack selected to improve the graphical alignment.

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