This data set was obtained during 2 ENVISION-IFREMER field campaigns carried out in 2007 and 2011 to sustain a Pectinid aquaculture project. This project was co-funded by ODEADOM and the public collectivity of Saint Pierre et Miquelon. Potential areas for further aquaculture exploitation and development on the Eastern coast of Saint Pierre et Miquelon.

Bathymetry of the French Guiana margin: the digital terrain model results from data compilation of 3 multibeam surveys conducted on the French research vessel RV L’Atalante. Grid resolution is 250 m. The DTM was processed as part of the French national program (EXTRAPLAC) for the delineation of the outer limit of the continental shelf beyond 200 nautical miles. - Guyaplac, 2003, R/V Atalante: Main source of the DTM was a cruise funded by the French National programme EXTRAPLAC. https://doi.org/10.17600/3010050 - Lobestory, 2004, R/V L'Atalante, https://doi.org/10.17600/4010030 - Cither1, 1993, R/V L'Atalante, https://doi.org/10.17600/93000010

This was co-funded by ODEADOM and the public collectivity of Saint Pierre et Miquelon. This work aims to assess new seeding and rearing areas for the King scallop Placopecten magellanicus through a site selection process using the bottom type mapping data set obtained during the 2 ENVISION-IFREMER field campaigns. Furthermore, new estimates of potental scallop production is produced by this data treatment.

Geomorphological analysis of the continental slope of the Mediterranean sea based on a 100m Data Terrain Model (DTM). This DTM is a synthesis of data acquired during sea surveys.

The definitive coastal information system, Quadrige stores coastal observation and monitoring network data. In order to manage coastal monitoring data, Ifremer developed the Quadrige² information system. Quadrige is one element of the Water Information System (SIE) http:// www.eaufrance.fr, et à ce titre, contribue aux travaux du Secrétariat d'Administration National des Données Relatives à l'Eau (SANDRE) http://www.sandre.eaufrance.fr. Quadrige Marine Zones is a reference source unique to the Quadrige system. It is used to break down the coast of the French mainland and overseas territories into large areas and to connect each one with observation and monitoring locations.
