In many estuaries, biogeochemical investigations have often focused on transient diatom biofilms that form on low‐energy intertidal flats. Studies on microphytobenthos in high‐energy sedimentary environments are unusual. The present investigation focuses on the biogeochemistry to a depth of 6 m of a...
