In the context of maritime spatial planning and the implementation of spatialized Good Environmental Status indicators in the Marine Strategy Framework Directive (MSFD), the definition of a mosaic composed of coherent and standardised spatial units is necessary. We propose here a characterization of seascapes in time and space within the specific framework of the MSFD in the English Channel and the Bay of Biscay areas. A spatio-temporal classification of coastal-shelf water masses is carried out using twelve essential oceanographic and derived variables from operational coastal oceanography using the HYCOM model. Partitioning is computed using a multivariate hybrid two-step clustering process defining a time series of categorical maps representing hydrographical patch classes. Main patch occurrence is analyzed to understand their spatio-temporal dynamics and their oceanographic characteristics. Finally, patch classes are combined with MSFD marine sub-region delimitations to build seascapes, including ecosystem approach management and marine policy considerations.

动态沿海货架海景，以沿海可操作海洋学来支持海洋政策：法国的例子

在海洋空间规划和在海洋战略框架指令（MSFD）中实施空间化的良好环境状态指标的背景下，必须定义由连贯且标准化的空间单元组成的镶嵌图。我们在这里提出了在英吉利海峡和比斯开湾地区MSFD特定框架内的时空海景特征。使用HYCOM模型，使用十二种基本海洋学和从可操作的沿海海洋学中得出的变量，对沿海搁板水体进行时空分类。使用多元混合两步聚类过程计算分区，该过程定义了代表水文补丁类的分类图的时间序列。分析主要斑块的发生，以了解其时空动态及其海洋学特征。最后，将斑块类别与MSFD海洋次区域定界相结合以构建海景，包括生态系统方法管理和海洋政策考虑因素。
