Fig. 3: Comparison of proxy data from ODP Site 1087 C with records from previously published data.

a Relative abundance of warmer-water (orange) and cooler-water species (blue), (b) Grass-pollen (%) considering the total pollen and spore sum from ODP Site 1081 (blue)51 and ODP Site 1085 (green)21 and (c) UK’37-derived SST (°C) record from ODP Site 1085 (magenta)5 and ODP Site 1087 (purple)69, (d) pCO2 proxy data compilation obtained from variety of different methodologies (https://paleo-co2.org) (references cited in Methods). Relative abundance (warmer and cooler water species) records between 6.1 Ma and the Holocene are obtained from Mohanty et al.11. Five-point running average plots are superimposed on (a, b) and thirty-point running average plots are superimposed on (d) (SST 1087) with dark lines. Dotted bar indicates the timing of initiation of the BUS, grey bar represents the LMC and blue bar represents the Late Miocene intensification of the BUS.
