These data were collected during the 2007 and 2011 ENVISION-Ifremer campaigns to sustain a R & D project focusing on the Pectinid aquaculture development. This project was co-funded by the Saint Pierre et Miquelon public body and ODEADOM. This work aims to assess and select new potential rearing areas for the King scallop Placopecten magellanicus by using bottom type data resulting from 2 mapping campaigns carried out in 2007 and 2011 on the Eastern coast of Saint Pierre et Miquelon archipelago.

Map of surficial sediments of the northern continental shelf of the Bay of Biscay at 1:500000 by Bouysse P. (coord.), Lesueur P. and Klingebiel A., 1986, conducted jointly by the BRGM and Ifremer.

This data set was obtained during 2 ENVISION-IFREMER field campaigns carried out in 2007 and 2011, to sustain a R & D project aimed to develop pectinid aquaculture. This project was co-funded by the St Pierre et Miquelon public collectivity and ODEADOM. This represents a synthesis of spatial analysis based upon multi-criteria to assess future seeding and rearing areas for King scallop Placopecten magellanicus on the Eastern coast of Saint Pierre et Miquelon.

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.
