Vibracore 9V1, Kailua Bay

Uniform succession of bioturbated, muddy, very fine- to fine-grained, Halimeda/carbonate sand: massive appearing (no obvious sedimentary structures) owing probably to extensive bioturbation; yellowish to light olive gray (5Y-8/1-6/1); poor to fair sorting with abundant mud (20 to 40+%) and 5-10% scattered skeletal fragments in the coarse to very coarse sand size; all sand size clasts angular to subangular; sand fraction dominantly Halimeda (29.0-43.5%) and foraminifera (17.5-24.0%), with common calcareous algae (7.0-8.5%) and coral fragments (6.5-7.0%) and minor echinoid fragments (2.5-3.5%) and calcareous sponge spicules (3.0-20.5%); abundant unidentifiable skeletal clasts (14.5-20.5%); owing to the very fine grain size (many probably coral fragments).
