Objective

Extension of the legal continental shelf of French Guyana based on the determining of the 2,500m isobath, the foot of the continental slope, and sedimentary thicknesses offshore. The operation was carried out in the framework of a contract with the Ministry of Industry. In application of article 7 of the DGEMP/Ifremer agreement concerning confidentiality (excerpt) "Any communication of data or study results acquired within the framework of the program concerned by this agreement is subject to DGEMP approval This falls under the EXTRAPLAC project.
