Vibracore 2V1, Kailua Bay

Uniform succession of bioturbated, very fine- to fine-grained, carbonate sand; massive appearing (no obvious sedimentary structures) owing to extensive bioturbation; yellowish gray (5Y8/1); fair to moderate sorting with scattered, coarse-grained skeletal fragments (2-5%); all sand size clasts angular to subangular; sand fraction composed of a mix of Halimeda (27.5-28.0%), coral fragments (15.5-19.0%), benthic foraminifera (12.5%) and calcareous algae (8.5-9.0%) with common calcareous sponge spicules (5.0-7.5%); minor volcanic rock fragments (2.0%) also abundant unidentifiable skeletal clasts (18.0-25.5%) owing to the very fine grain size.
