TDI-Brooks International, Inc (under contract to TGS), has completed the offshore multibeam phase offshore the Niger Delta. This survey took place in water depths of 750 to 3,500 meters and is Nigeria’s first regional multi-client Multibeam and Seafloor Sampling (MB&SS) Study. TDI-Brooks’ R/V Gyre acquired 82,000 square kilometres of high-resolution hull-mounted multibeam echo sounder data. During the multibeam data collection a total of 1,223 active hydrocarbon seeps were detected in the multibeam water column data. Onboard hydrocarbon seep analysis was conducted in near real-time onboard the vessel to expedite the process of core selection. The Gyre is fitted with an EM302 MBES (EM304 upgrade pending). The R/V Proteus is scheduled to begin acquisition of the follow-up Surface Geochemical Exploration (SGE) coring campaign in July 2020, where approximately 245 piston core samples targeting suspected seep features selected from the MBES dataset will be collected, along with an additional 45 additional piston core samples for geotechnical and biostratigraphic studies. www.tdi-bi.com
