国际社会正在努力在南大洋建立一个有代表性的海洋保护区系统，以帮助长期保护该区域的海洋生物多样性。对这项工作很重要的是了解海底生物群的分布情况。在这里，我们的目标是确定底栖海洋生物组合可能会有所不同，彼此在南大洋，包括近岸南极洲的地区。我们实现这一目标，通过使用生态区，bathomes和环境类型的层次空间分类。生态区是根据现有的地理格局和环境驱动因素的扩散数据来定义的。根据物种分布所定义的深度层来识别群落。环境类型是根据每个生态区的海底槽内发现的地貌特征进行独特分类的。我们确定了23个生态区和9个浴区。从28种海底地貌特征中，为南大洋划分了562种独特的环境类型。我们应用环境类型作为不同生物多样性组合的替代品，以评估现有海洋保护区的代表性。我们发现，12个生态区没有代表在海洋保护区，没有生态区有其完整的环境类型在海洋保护区。目前的MPA规划过程，如果实施，将大大增加环境类型的代表性，特别是在8个生态区。为了实现国际商定的保护目标，将需要更多的海洋保护区。为了协助这一进程，我们确定了107个空间限制的环境类型，应考虑纳入未来的海洋保护区。提供了详细的补充数据，包括空间数据集。
An international effort is underway to establish a representative system of marine protected areas (MPAs) in the Southern Ocean to help provide for the long-term conservation of marine biodiversity in the region. Important to this undertaking is knowledge of the distribution of benthic assemblages. Here, our aim is to identify the areas where benthic marine assemblages are likely to differ from each other in the Southern Ocean including near-shore Antarctica. We achieve this by using a hierarchical spatial classification of ecoregions, bathomes and environmental types. Ecoregions are defined according to available data on biogeographic patterns and environmental drivers on dispersal. Bathomes are identified according to depth strata defined by species distributions. Environmental types are uniquely classified according to the geomorphic features found within the bathomes in each ecoregion. We identified 23 ecoregions and nine bathomes. From a set of 28 types of geomorphic features of the seabed, 562 unique environmental types were classified for the Southern Ocean. We applied the environmental types as surrogates of different assemblages of biodiversity to assess the representativeness of existing MPAs. We found that 12 ecoregions are not represented in MPAs and that no ecoregion has their full range of environmental types represented in MPAs. Current MPA planning processes, if implemented, will substantially increase the representation of environmental types particularly within 8 ecoregions. To meet internationally agreed conservation goals, additional MPAs will be needed. To assist with this process, we identified 107 spatially restricted environmental types, which should be considered for inclusion in future MPAs. Detailed supplementary data including a spatial dataset are provided.
