P565 DISTRIBUTION OF BOTTOM SIMULATING REFLECTORS (BSRS) AND GAS HYDRATES OFF COSTA RICA H. MEYER B. BUTTKUS S. NEBEN and C. BÖNNEMANN Bundesanstalt für Geowissenschaften und Rohstoffe Stilleweg 2 30655 Hannover Germany The convergent continental margin off Costa Rica is an area with large known gas hydrate occurrences. 1 At this margin BGR undertook in 1992 a 3D seismic survey and acquired 2D seismic lines during several cruises. One major aim of cruise BGR99 was to map the overall gas hydrate distribution as inferred from BSR occurrence along the convergent margin off Costa Rica and especially to collect high resolution
