The Moira Mounds, small cold-water coral mounds in the Porcupine Seabight, NE Atlantic: Part B-Evaluating the impact of sediment dynamics through high-resolution ROV-borne bathymetric mapping

►ROV-borne micro-bathymetry has mapped small Moira Mounds and associated bedforms. ►Current speeds, sediment dynamics and tidal currents are crucial in mound build-up. ►The balance between erosion and deposition plays a crucial role in mound build-up. ►The Moira Mounds represent mound formation under stressed conditions.
