English: Map of the deepest section of the Diamantina Fracture Zone with the locations of published ‘deeps’ (red circles) (Table 1). The 6000 m depth contour is shown in white. The deepest section of the feature is defined by the 7000 m contour (blue). All other contours at 200 m intervals (between 6000 and 7000 m water depth) (B) Inset map of Dordrecht Deep with the deepest point determined during this study (white star = between 7090 and 7100 m water depth) which is within 4 km of the published GEBCO Gazetteer location for Dordrecht Deep. The outer rim of Dordrecht deep lies at 5300 m water depth (pink contour). The 7000 m contour is coloured blue. All other contours at 100 m intervals (between 5300 and 7000 m water depth). For location of inset map see the red box in Fig. 5A. Illumination from 45° at an altitude of 25°.
