L’enquête de 1665 et sa valeur hydrographique pour retracer l’histoire environnementale du coureau d’Oléron

Abstract : In 1665, Colbert launched an investigation to choose a port to shelter the modern naval fleet that he had convinced Louis XIV to create. This investigation was instigated a few years prior to the decisive scientific advances of the reign. The 1 April 1665, an officer of the Admiralty of Marennes embarked for a reconnaissance mission of the natural harbour, the coureau d’Oléron, with six sailors of Brouage whose testimonies require verification. Soundings realised during this mission gave precious indications and, thanks to a multidisciplinary approach, it is possible to analyse them. These six soundings effected in 1665 can be transferred in the current hydrographic mark and compared with the more and more precise maps published over the following centuries. The results of this cross analysis suggest the construction of a submarine landscape stemming from natural mechanisms but also from the influence of coastal societies.
