Based on an already scheduled expedition with RV POSEIDON (29.6.-15.7.2010) the Holocene development of cold-water coral ecosystems in the Belgica Mound Province in the Porcupine Seabight off Ireland will be investigated. Thereby special emphasis will be given to the question lo what extent the vitality of cold-water coral ecosystems on carbonate mounds throughout the Holocene responded to variations in the regional water mass structure. In the Belgica Mound Province three carbonate mound chains exist in different water depths. With significant variations in their recent coral coverage, these mound chains offer an optimal setting to investigate the relation between coral vitality and water mass structure. The planned work will concentrate on detailed video surveys of the coral coverage on these mounds with the Bremen ROV Cherokee. In addition, sediment cores will be retrieved from the mound chains as well as from the surrounding seafloor to investigate the relation between coral growth and regional paleoceanography during the Holocene. The main aim of this project is the detailed examination of the Holocene development of the cold-water coral ecosystems in this region in dependence of the prevailing oceanographic setting.

根据已安排的 RV POSEIDON 探险（2010 年 6 月 29 日至 7 月 15 日），将对爱尔兰豪猪湾 Belgica Mound 省冷水珊瑚生态系统的全新世发展进行调查。因此，将特别强调整个全新世碳酸盐丘上冷水珊瑚生态系统的活力在多大程度上对区域水体结构的变化作出反应的问题。在 Belgica Mound 省，三个碳酸盐丘链存在于不同的水深中。由于最近的珊瑚覆盖范围存在显着变化，这些土丘链为研究珊瑚活力与水团结构之间的关系提供了最佳环境。计划的工作将集中于使用 Bremen ROV Cherokee 对这些土丘上的珊瑚覆盖情况进行详细的视频调查。此外，将从土丘链以及周围海底取回沉积物岩心，以研究全新世期间珊瑚生长与区域古海洋学之间的关系。该项目的主要目的是根据当时的海洋环境详细研究该地区冷水珊瑚生态系统的全新世发展。
