Statement

Sample processing was performed at Utrecht University, following standard techniques of the Laboratory of Palaeobotany and Palynology. Samples were oven-dried and weighed (~15 g dry weight sediment each). One Lycopodium clavatum tablet with a known amount of marker spores was added for quantification of palynomorph abundances (Wood et al., 1996). Samples were treated with 10% HCl (Hydrochloric acid) and cold 38% HF (Hydrofluoric acid), then sieved over a 10 μm mesh with occasional mild ultrasonic treatment. To avoid any potential processing-related preservation bias, no oxidation or acetolysis was carried out. The processed residue was transferred to microscope slides using glycerine jelly as a mounting medium, and 2 slides were analysed per sample at 400× magnification. Slides were examined for detailed marine (dinoflagellate cysts, acritarchs and other aquatic palynomorphs) and screening-level terrestrial (pollen and spore) analysis at Utrecht University, with a subsequent detailed analysis for terrestrial palynomorphs on a sub-set of seven samples undertaken at GNS Science. Of the 23 palynological samples analysed for dinocysts, two contained <60 dinocysts (594.48 and 567.75 mbsf) and one was almost barren (yielding only 12 in situ dinocysts, 374.9 mbsf). The low abundance samples are included in our dataset; however, because of the low dinocyst yield, careful interpretation is required. Pollen and spore identification followed taxonomic compilations (Raine et al. 2011; Prebble 2016), augmented by key Antarctic literature (Askin, 2000; Askin and Raine 2000; Truswell, 1983). For pollen and spores, scanning continued until an entire cover slide was completed, or a 100 count reached. Dinocysts were identified based on a taxonomical index (Fensome and Williams, 2004) and informally and formally described species in the literature (Hannah et al., 2000; Hannah, 2006; Clowes et al., 2016; Bijl et al., 2018).
