| La dynamique des masses d'eau et les flux de transit semblent favoriser un comblement et/ou des limitations de renouvellement d'eau mettant en péril la durabilité de l’environnement de cette lagune Miquelonnaise. La Préfecture de Saint Pierre et Miquelon et la DTAM, en soutien à la gestion durable de cet environnement, ont sollicité l’Ifremer pour l’évaluation des flux d’alimentation de cette lagune. Une mission sur place a été réalisée en juin 2016, pour coordonner les actions et effectuer un certain nombre de mesures préliminaires (jaugeages et bathymétrie du chenal, courantométrie horizontale). Ces données sont complétées par une acquisition continue des vitesses de courant, avec des données disponibles à ce jour du 2 juin au 15 novembre 2016.... |

| Initiated in 2013, the present work carried out in 2014 extends the monitoring network focusing on marine invasive exotic species in Saint-Pierre and Miquelon archipelago. In a global context of coastal ecosystems’ changes, accentuated by direct or indirect effects of human activities, it became essential to implement a monitoring survey and to track the expansion of marine invasive species along Saint-Pierre and Miquelon shoreline. Fukui traps and tunicates collectors deployed on different stations as well as the timely completion of observational dives, have provided the following conclusions: several invasive species were again reported within the local marine ecosystem. Those species, i.e., Carcinus maenas, Caprella mutica, Ciona intestinalis,... |

| This work, conducted in 2013 , is a first monitoring of marine invasive species in Saint-Pierre and Miquelon archipelago. In global changing context on coastal ecosystems , accentuated by direct or indirect effects of human activities, it became essential to implement a survey on marine invasive species on Saint-Pierre and Miquelon shoreline. Fukui traps and tunicates collectors implemented on different stations as well as the timely completion of observational dives , have established the following conclusions : several non native species were detected within the local marine ecosystem. This species , such as Carcinus maenas , Ciona intestinalis , Botryllus schlosseri , Caprella mutica , etc. ... threaten some local marine ecosystems and some local... |
