Sediment accumulation in a shallow-water meadow carpeted by a small erect bryozoan

A marine meadow covered 80-90% by a turf of erect bryozoan Cellaria occurs over an area >104 m2 west of Banjole Island (Croatia) in the northeastern Adriatic Seas. Surrounding areas are bare to pachily covered by isolated clumps of bryozoans, sponges, and ascidians attached to scattered shell ans rock debris. Silt and clay comprise >90% of the mass of sediment within the meadow, and Cellaria branch fragments are the next-most-abundant component. From 13 to at least 25 cm depth in the meadow sediment coralline algal branch fragments are abundant, and silt and clay comprise over 50% of the sediment's mass. In contrast, sediment accumulated in the bare area adjacent to the meadow is predominatly coarse carbonate sand, composed of diverse skeletal grains. Mud comprises <50% of this sediment. cool-water carbonate
