Figure 1

Bathymetric map of the eastern North Atlantic showing the approximate geographic sampled locations and sample sizes per location. Geographic locations are based on GPS coordinates or reported discovery location. The bar scales delimit the latitudinal range of the three spatial scales considered for the analyses of the North Atlantic (NAt) cluster: the global scale (1); the middle scale, south (2A), and north (2B) parts; and the small scale, the south (3A), middle (3B), and north (3C) parts. The map is projected using a gnomonic projection centred on the sampling centroid (scale units in km).
