在北方豪猪湾（东北大西洋）600至1000米深处发现了大型碳酸盐丘结构。这些土丘与深海珊瑚Lophelia pertusa和Madelia oculata的生长有关。在这项研究中，分析了三个沉积物岩心。它们来自靠近螺旋桨丘的地方，螺旋桨丘是一个150米高的山脊状特征，其上翼覆盖着冷水珊瑚生态系统。调查工作集中于粒度分析、碳测量以及岩心和计算机断层扫描图像的直观描述，以评估沉积物的含量和结构。
Large carbonate mound structures have been discovered in the northern Porcupine Seabight (Northeast Atlantic) at depths between 600 and 1000 m. These mounds are associated with the growth of deep-sea corals Lophelia pertusa and Madrepora oculata. In this study, three sediment cores have been analysed. They are from locations close to Propeller Mound, a 150 m high ridge-like feature covered with a cold-water coral ecosystem at its upper flanks. The investigations are concentrated on grain-size analyses, carbon measurements and on the visual description of the cores and computer tomographic images, to evaluate sediment content and structure.
