“…It is supported by the simultaneous deposition of fine sediments on the coral mound, which clearly point to a sediment bypass situation in the area adjacent to the coral mound. A likely related contemporaneously increased supply of sediment (and food) particles was also suggested to be a trigger for the most recent major coral mound formation period documented for various coral mounds in the southern Alborán Sea since the last deglaciation (Fink et al, 2013;Stalder et al, 2015Stalder et al, , 2018Wang et al, 2019;Fentimen et al, 2020;Corbera et al, 2021).…”

“…The coral mound AR under this scenario is low to moderate (<100 cm kyr −1 ) and mainly controlled by sediment supply. Such coral rubble-dominated mound deposits are frequently described in the Mediterranean Sea (e.g., Stalder et al, 2015;Titschack et al, 2016;Wang et al, 2019;Corbera et al, 2021) as well as in the Atlantic (Eisele et al, 2008;Frank et al, 2009).…”

“…Despite the high sediment supply, the mound AR is low (<10 cm kyr −1 ) and mound formation is mainly controlled by the limited coral-derived ecological accommodation space. This scenario is often encountered close to phases of coral mound stagnation, expressed as hiatuses, condensed sections or significant drops in ARs, which are frequently described from various coral mound provinces in the Atlantic and Mediterranean Sea (Dorschel et al, 2005;Rüggeberg et al, 2007;Foubert and Henriet, 2009;Frank et al, 2009;Mienis et al, 2009b;Wienberg et al, 2018;Corbera et al, 2021).…”

The Importance of Ecological Accommodation Space and Sediment Supply for Cold-Water Coral Mound Formation, a Case Study From the Western Mediterranean Sea

The formation of cold-water coral (CWC) mounds is commonly seen as being the result of the sustained growth of framework-forming CWCs and the concurrent supply and deposition of terrigenous sediments under energetic hydrodynamic conditions. Yet only a limited number of studies investigated the complex interplay of the various hydrodynamic, sedimentological and biological processes involved in mound formation, which, however, focused on the environmental conditions promoting coral growth. Therefore, we are still lacking an in-depth understanding of the processes allowing the on-mound deposition of hemipelagic sediments, which contribute to two thirds of coral mound deposits. To investigate these processes over geological time and to evaluate their contribution to coral mound formation, we reconstructed changes in sediment transport and deposition by comparing sedimentological parameters (grain-size distribution, sediment composition, accumulation rates) of two sediment cores collected from a Mediterranean coral mound and the adjacent seafloor (off-mound). Our results showed that under a turbulent hydrodynamic regime promoting coral growth during the Early Holocene, the deposition of fine siliciclastic sediments shifted from the open seafloor to the coral mounds. This led to a high average mound aggradation rate of >130 cm kyr–1, while sedimentation rates in the adjacent off-mound area at the same time did not exceed 10 cm kyr–1. Thereby, the baffling of suspended sediments by the coral framework and their deposition within the ecological accommodation space provided by the corals seem to be key processes for mound formation. Although, it is commonly accepted that these processes play important roles in various sedimentary environments, our study provided for the first time, core-based empirical data proving the efficiency of these processes in coral mound environment. In addition, our approach to compare the grain-size distribution of the siliciclastic sediments deposited concurrently on a coral mound and on the adjacent seafloor allowed us to investigate the integrated influence of coral mound morphology and coral framework on the mound formation process. Based on these results, this study provides the first conceptual model for coral mound formation by applying sequence stratigraphic concepts, which highlights the interplay of the coral-framework baffling capacity, coral-derived ecological accommodation space and sediment supply.

“…In addition, other studies revealed a large scale distribution of clustered mounds with circular to elongated footprints along the Alboran Sea margins [43,55,[58][59][60][61]. The clustering of mounds in extensive fields, especially along the upper and middle slopes, has been recently documented in the southern and central Alboran Sea, especially in the East [43,61] and West Melilla CWC mound provinces [46,55], as well as in the Cabliers bank [62,63] (Figure 1A). Furthermore, three mound fields have been located within the contouritic terraces of the northern Alboran Sea margin (south-eastern Spain), in front of Marbella (around the Torrenueva submarine canyon), in front of Málaga and southwest off Almería [6,58,59,64].…”

Morphosedimentary, Structural and Benthic Characterization of Carbonate Mound Fields on the Upper Continental Slope of the Northern Alboran Sea (Western Mediterranean)

Carbonate mounds clustering in three fields were characterized on the upper continental slope of the northern Alboran Sea by means of a detailed analysis of the morphosedimentary and structural features using high-resolution bathymetry and parametric profiles. The contemporary and past benthic and demersal species were studied using ROV underwater imagery and some samples. A total of 325 mounds, with heights between 1 and 18 m, and 204 buried mounds were detected between 155 to 401 m water depth. Transparent facies characterize the mounds, which root on at least six erosive surfaces, indicating different growth stages. At present, these mounds are covered with soft sediments and typical bathyal sedimentary habitat-forming species, such as sea-pens, cerianthids and sabellid polychaetes. Nevertheless, remains of colonial scleractinians, rhodoliths and bivalves were detected and their role as potential mound-forming species is discussed. We hypothesized that the formation of these mounds could be related to favorable climatic conditions for cold-water corals, possibly during the late Pleistocene. The occurrence on top of some mounds of abundant rhodoliths suggests that some mounds were in the photic zone during minimum sea level and boreal guest fauna (e.g., Modiolus modiolus), which declined in the western Mediterranean after the Termination 1a of the Last Glacial (Late Pleistocene).
