The data were acquired during three research cruises in the Maldives: in 2007 (German RV METEOR; cruise M74/4 NEOMA), 2011 (dive safari vessel HOPE CRUISER, CURRDROW) and 2014 (German RV SONNE, cruise SO236 MALSTROM). The Maldives archipelago is among the world's largest carbonate platforms. It formed during the Cenozoic in a regime of high-amplitude sea-level fluctuations, global climate cooling, palaeo-oceanographic change as well as the onset of the monsoon regime. The aim of the cruises was to unravel the record of these changes, especially for the Miocene to Recent time interval, in order to investigate the response of the platform to such processes. The data comprises multi-channel reflection seismic, Parasound and boomer (sub-bottom profiler), as well as ADCP (acoustic doppler current profiler) data.
