Relative abundance of diatoms is shown at lowest taxonomic level resolved from sedaDNA at Exp. 382 Sites U1534 (Hole C) (a), U1536 (Hole B) (b) and U1538 (Holes C and D) (c), post combined SSU + LSU alignment. Left axis shows the estimated age (where an age but no bar is shown, no diatom reads were identified in that sample). For sample details, see Table 1. ML = mudline. Arrows indicate the start of increased, consistent presence of C. affinis (14.5 ka) and H. sinensis (12.7 ka) at Site U1538. Total diatom read count: 27,707 reads. Source data are provided as a Source Data file.
