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.

根据已经安排的与RV Poseidon(2010年6月29日至7月15日)的探险，将调查爱尔兰近海豪猪海岸Belgica Mound省全新世冷水珊瑚生态系统的发展。因此，将特别强调这样一个问题，即整个全新世碳酸盐丘上的冷水珊瑚生态系统的活力在多大程度上对区域水团结构的变化作出了反应。在贝尔吉卡丘陵省，三条碳酸盐丘链存在于不同的水深。随着最近珊瑚覆盖率的显著变化，这些丘状链为研究珊瑚活力和水团结构之间的关系提供了一个最佳环境。计划中的工作将集中在利用不来梅ROV切诺基对这些土丘上的珊瑚覆盖进行详细的视频调查。此外，将从丘链以及周围海底提取沉积物岩芯，以调查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，详细研究该区域冷水珊瑚生态系统的全新世发展情况。
