a Total organic carbon87. b Carbonate fine-fraction ( <20 µm) δ13C and δ18O records. Indicators of marine influence. c Foraminiferal planktonic:benthic ratio29. Salinity: (d) ratio of Spiniferites spp. with long-to-short processes; (e) relative abundance of low salinity intolerant Homotryblium spp. within dinocysts. Continental influence (relative abundance within total palynomorphs – f–h): (f) plant resin; (g) plant cuticle; (h) freshwater algae Pediastrum spp. Productivity: (i) ratio of peridinioid to gonyaulacoid (P/G) dinocysts. Main negative isotope excursion at MGC is indicated as a shaded bar. Key: epoch – Pleistocene (Pl.); lithostratigraphic units – Forest Hill Formation (FH), Moodys Branch Formation (MB), Cockfield Formation (Cf). Source data are provided as a Source Data file.
