Shape and Size Complexity of Deep Seafloor Mounds on the Canary Basin (West to Canary Islands, Eastern Atlantic): A DEM-Based Geomorphometric Analysis of Domes and Volcanoes

Abstract: Abstract:Derived digital elevation models (DEMs) are high-resolution acoustic technology that has proven to be a crucial morphometric data source for research into submarine environments. We present a morphometric analysis of forty deep seafloor edifices located to the west of Canary Islands, using a 150 m resolution bathymetric DEM. These seafloor structures are characterized as hydrothermal domes and volcanic edifices, based on a previous study, and they are also morphostructurally categorized into five type… Show more

“…As we have demonstrated, quantitative analysis of pockmark morphology can provide valuable insights into the factors that control their formation and development. Supported by the wider availability of high resolution bathymetry data and appropriate DTM-based methodologies for morphometric analysis, we hope that more studies linking morphological trends to geological processes will be forthcoming in the literature, such as the one in this Special Issue by [46]. We hope the results of such studies will also be carried forward in validating numerical models of the development of seabed features.…”

“…For many of the artefacts presented, their manifestation is most apparent in the outer part of the swath corridor (e.g., Figures 5,6,8,9 and 11). Thus, depending on the level of swath to swath overlap, their visibility may or may not be preserved in the final grid product.…”

“…The other papers [6][7][8][9][10] present specific applications, predominately utilizing multibeam sonar observations. The scales of features investigated vary by two orders of magnitudes including deep-water (2000-5200 m) observations [6,7], outer shelf (135-376 m) [8], and shallow (10-50 m) water [9][10][11]. For all cases, the features of interest range from 0.2 to 10% of the total water depth in the vertical and 2-20% of the elevation in the horizontal.…”

“…Their approach proved to be less subjective and faster than traditional methods, such as manual expert identification and delineation. Sánchez-Guillamón et al [37] used morphometry and size to classify deep seafloor mounds, such as domes and volcanoes, in the Canary Basin and proposed a growth model of those mounds informed by their geomorphometric characteristics. It is also noteworthy that many studies have both a geomorphological focus and a habitatmapping focus that complement each other.…”
