ABSTRACT

The Alghero Bay is a coastal area of high economic value because of the presence of one of the most popular beaches of Sardinia (San Giovanni, Maria Pia, Le Bombarde, Lazzaretto). The organisms living in the meadow of Posidonia oceanica, which densely cover the offshore areas of the bay, represent the most important source of sediments to these beaches. For this reason, a detailed mapping of the local seabed features and distribution of P. oceanica constitutes an important tool for the coastal managing of the area. The integrated use of several methodologies, such as Side Scan Sonar, Remote Operating Vehicle, Drone and direct sediment sampling has allowed us to realize a very detailed seafloor map of the Alghero Bay.

摘要

阿尔盖罗湾是撒丁岛最受欢迎的海滩之一（圣乔瓦尼，玛丽亚·皮亚，勒庞巴德，拉扎列托），是具有很高经济价值的沿海地区。生活在波西多尼亚大洋洲草地上的生物密集地覆盖了海湾的近海区域，是这些海滩最重要的沉积物来源。因此，详细绘制当地海床特征和海洋假单胞菌的分布构成了对该地区进行沿海管理的重要工具。多种方法的综合使用，例如侧面扫描声纳，远程操作车辆，无人机和直接沉积物采样，使我们能够了解阿尔盖罗湾非常详细的海底地图。
