(A) Location of the Maldives with main wind directions. (B) Inner Sea with two rows of atolls. (C) Satellite and multibeam imagery with position of IODP Expedition 359 sites. The seaway connecting the Inner Sea with the Indian Ocean formed through the demise of two N-S oriented continuous carbonate banks. Demise occurred in steps, as shown by the occurrence of drowned relict banks. The tear-drop shapes of the drowned atolls indicate the presence of a west-directed current flowing through the newly formed marine passage8. White lines: position of seismic line shown in Figs 2 and S1. Maps were produced using the program Esri ArcMap 10.1 (www.esri.com). Bathymetric data in A and B were exported as Geotiffs from the application GeoMapApp 3.6.0 (www.geomapapp.org). In C, Worldwind satellite images (http://worldwind.arc.nasa.gov/java) were merged with multibeam data acquired during the cruises M74/4 and SO236.
