This dataset presents the relative diatom abundances of 55 species/groups from the 132-120 ka interval in marine sediment core TPC290 (-55.55 degN, -45.02 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
