The Messina Strait and the studied sand-wave field.

(a) Bathymetric map of the Messina Strait (map generated by SURFER 10.2 http://www.goldensoftware.com/products/surfer). The box shows the sand-wave field over the topographic mound off Capo Rasocolmo (CR); the red star indicates position of the NOMEC3 current-meter and the dashed red line indicates orientation of the reference system of the current-meter data (See Fig. 2d). In plan-view, sand-waves have linear or slightly sinuous crest-lines that are mostly oriented obliquely to the isobaths; their crest-lines are laterally continuous southward (close to the Messina Strait), whereas they become more discontinuous northwards. The location of the Messina Strait (central Mediterranean Sea) is shown in the upper-left panel. (b) 3D zoom of the sand-wave field (map generated by CARIS Easy View 4.1 http://www.caris.com/products/easy-view). The black line indicates the bathymetric section in (c). (c) Bathymetric section of sand-wave crests. Sand waves show variable cross-sections, from asymmetric (longer stoss side followed by shorter and steeper lee side) to more symmetric moving northward.
