Vibracore 17V1, Leeward coast

Uniform succession of vaguely-laminated to massive (bioturbated), medium-to coarse-grained, algal/coral/foraminiferal carbonate sand: massive appearing (no obvious sedimentary structures) owing probably to extensive bioturbation; light olive to olive gray (5Y6/1-4/1); moderate sorting; sand size clasts subrounded to rounded; composed mainly of a mix of calcareous algae (27.0-34.0%) coral fragments (19.5-27.0%) and foraminifera (15.0-21.0%) with abundant carbonate rock fragments (9.0-11.5%) and volcanic rock fragments (5.5-8.5%); minor echinoid fragments (2.0-2.5%), mollusks (3.0%) and Halimeda (0.5-1.0%).
