Cold‐water corals (CWCs) along the NE Atlantic margin show a temporally and spatially structured occurrence over the last glacial‐interglacial cycle that indicates a close coupling between these ecosystems and climate (i.e. environmental) change. Off NW Africa corals have been widespread during the last glacial and largely demised at the end of this cold period. In contrast, corals off northern Europe started to develop to the most vivid CWC sites worldwide during the recent interglacial. This pattern points to a climate induced northward shift of areas with optimum coral growth conditions with the onset of the Holocene likely caused by dramatic environmental changes that occurred during this time in the North Atlantic realm. However, the main factors controlling the prosperity and demise of CWCs are only partly understood. Moreover, a potential connectivity between the NE and NW Atlantic coral occurrences has not been considered so far, which is mainly attributed to a lack of appropriate data from NW Atlantic coral sites. Therefore, the proposed project will be based on sample material to be collected from CWC sites along the NW Atlantic margin during a cruise with RV MARIA S. MERIAN in spring 2012 and will be correlated with existing data already obtained for the NE Atlantic. The overall aim is to study the development of CWC ecosystems under changing environmental conditions during the last glacial‐interglacial cycle on a trans‐Atlantic perspective and to identify the underlying controlling factors.

东北大西洋边缘的冷水珊瑚(CWCS)在上一次冰期-间冰期循环中表现出时间和空间结构的变化，表明这些生态系统与气候(即环境)变化之间存在密切的耦合。在非洲西北部外，珊瑚在上一次冰川期间广泛存在，并在这一寒冷时期结束时基本灭绝。相比之下，北欧的珊瑚在最近的间冰期开始发展成为世界上最生动的化学武器公约遗址。这种模式表明气候导致珊瑚生长条件最佳的地区向北转移，全新世的开始可能是由北大西洋领域在此期间发生的戏剧性环境变化引起的。然而，人们对控制CWCS兴衰的主要因素只有部分了解。此外，到目前为止还没有考虑东北和西北大西洋珊瑚产状之间的潜在连通性，这主要是因为缺乏来自西北大西洋珊瑚产地的适当数据。因此，拟议的项目将以2012年春季乘坐玛丽亚·S·梅里安房车巡航期间从西北大西洋边缘的化学武器公约地点收集的样本材料为基础，并将与东北大西洋已获得的现有数据相关联。总体目标是从跨大西洋的角度研究上一次冰川-间冰期循环期间在不断变化的环境条件下化学武器公约生态系统的发展情况，并查明潜在的控制因素。
