The importance of ecological accommodation space and sediment supply for cold-water coral mound formation, a case study from the Western Mediterranean Sea

By comparing the sedimentary parameters between two sediment cores that collected from coral ridge and adjacent seafloor (southern Alboran Sea, western Mediterranean Sea), we reconsructed the sedimentary process during the mound formation. Furthermore, we provide the first conceptual model of coral mound formation that highlights the role of coral-derived ecological accommodation space and sediment supply. The dataset provide the grain size, matrix sediment bulk dry density, sediment composition and associated accumulation rate of the matrix sediment from the two sediment cores. Besides, the comparison of average grain-size distribution and accumulation rate of siliciclastic sediment are provided
