Figure F13. SEM photomicrographs of the dominant coccoliths observed on smear slides prepared from (A–C) Sample 331-C0014A-1H-1, 1–2 cm (0.01 mbsf), and (D) Sample 331-C0014B-1H-CC, 24.5–25.5 cm (7.0 mbsf). Although not exclusive to the deeper sample, note the typical loss of structural integrity (i.e., the bridge in coccoliths recovered from [D] the bottom of Core 331-C0014B-1H versus those recovered from [B] the surface of Core 331-C0014A-1H). A. Emiliania huxleyii var. corona (arrow) and Gephyrocapsa oceanica (two coccoliths). B. Gephyrocapsa oceanica; note preservation of the bridge. C. Emiliania huxleyii var. huxleyii. D. Gephyrocapsa oceanica.
