Uniform succession of burrowed to bioturbated, very fine- to medium-grained, algal/coral/foraminifera/ carbonate sand: massive appearing with irregular, large burrow structures (20-30 cm long); light olive to olive gray (5Y6/1-4/1); poor sorting; sand size clasts angular to rounded; composed mainly of a mix of calcareous algae (32.0-32.5%), coral fragments (29.0-31.5%) and foraminifera (19.0-21.5%); minor Halimeda (4.5%), mollusks (2.5-3.0%) and echinoid fragments (1.5-2.5%).

Vibracore 26V1
Uniform succession of burrowed to bioturbated, fine- to medium-grained, algal/coral/foraminiferal carbonate sand: massive appearing owing to biomixing; light olive to olive gray (5Y6/1); moderate sorting; sand composed mainly of a mix of calcareous algae, coral fragments, and foraminifera.
