Geomorphological mapping of the Belgian seabed and its submerged landscapes
- Low- and high-resolution Digital Terrain Models (DTMs) are available as interoperable gridded data layers and data products. These bathymetry data, together with increasing availability of various terrain analysis tools, give new impetus to a more uniform geomorphological mapping of the marine realm. To test approaches in sandy shelf areas, a multi-scale analysis was already performed on bathymetric data from the Belgian part of the North Sea using the Benthic Terrain Modeler (BTM) in ArcGIS and other GIS-related raster tools for analysing the topography of the seabed. Geomorphological features present on the Belgian Continental Shelf are sandbanks and crests, valleys and depressions, and sandwave fields. Recently, a derivative of the digital bathymetry model was constructed based on in-depth processing and re-interpretations of sediment cores in conjunction with extensive seismic records, resulting in a depth-converted structure map (DCSM) of the Top-Paleogene surface at high-resolution scale of 1:250 000 (De Clercq et al., 2016). Similar GIS analyses have now been conducted on the appearing submerged landscapes from 120,000 to 100,000 years ago allowing revealing planation surfaces, escarpements, slope breaks, paleo-valleys and -ridges in an automated way. Both resulting geomorphological mapping products contribute to EMODnet-Geology’s work packages on geomorphology and submerged landscapes.

How different are the Kebara 2 ribs to modern humans?
- This study analyses rib geometric parameters of individual ribs of 14 modern human subjects (7 males and 7 females) in comparison to the reconstructed ribs of the Kebara 2 skeleton which was taken from the reconstruction of a Neandertal thorax by Sawyer & Maley (2005). Three-dimensional (3D) models were segmented from CT scans and each rib vertex cloud was placed into a local coordinate system defined from the rib principal axes. Rib clouds were then analysed using best fitting ellipses of the external contours of the cross-section areas. The centroid of each ellipse was then used to measure the centroidal pathway between each slice (rib midline). Curvature of the ribs was measured from the mid-line of the ribs as the sum of angles between successive centroids in adjacent cross sections. Distinct common patterns were noted in all rib geometric parameters for modern humans. The Kebara 2 reconstructed ribs also followed the same patterns. This study demonstrated that there are differences between the sexes in rib geometrical parameters, with females showing smaller rib width, chord length and arc length, but greater curvature (rib torsion, rib axial curvature, rib anterior-posterior bending) than males. The Kebara 2 reconstructed ribs were within the modern human range for the majority of geometrical parameters.
