| Oyster farm structures represent artificial obstacles which can disturb tidal currents and wave propagation, and thus modify sediment transport patterns. Local deposition may result from these modifications, in proportions that may threaten the oyster farming. The impact of structures on hydrodynamics, waves and currents, is investigated at different spatial scales by means of in-situ measurements, experimental tests and numerical modeling. These different approaches show that in the near-field, tidal currents are modified in terms of intensity and direction but there is no significant impact on the waves. On the other hand, at the scale of the oyster farm, a significant reduction of the current velocities and a large wave height attenuation are recorded.... |

| La demande faite à l’Ifremer par le département de la Charente Maritime concerne la qualification et caractérisation de sites à potentiel hydrolien, déjà sélectionnés lors de précédentes études, à l’aide des données de type bathymétriques, et hydrodynamiques disponibles au LERPC de La Tremblade. Cela consiste à 1) Fournir les données de bathymétrie à la plus haute résolution disponible sur les sites choisis sous mise en forme de couche SIG, 2) fournir et expliciter les données de Courants ADCP réalisées par le laboratoire (J.Y. Stanisière, 2007-2013), 3) utiliser des données de courant du modèle Mars3D- PC existantes (P. Polsenaere & O. Le Moine, 2014-2017) pour en extraire après post traitement un certain nombre de variables chronologiques et/ou... |

| This report reviews the data obtained during Leg1 and Leg2 of the TURBIDENT oceanographic campaign (May-October 2018) carried out in the Iles d'Or (Toulon) area to the Banc des Blauquières (Cassis), within the framework of the ANR ASTRID Turbdident. The objective of this campaign was to acquire an innovative data set providing relevant information on the ocean surface layer under the illumination zone of the MIO HF radar, in particular sub-surface current profiles obtained using acoustic Doppler current meters (ADCP) operating in a stabilised manner below the surface from an autonomous underwater vehicle (AUV) from Ifremer, and temperature profiles obtained using low-cost thermistor lines developed in-house, in addition to more conventional measurements of... |
