The skeletons of long-lived bamboo coral (Family Keratoisididae) are promising archives for deep-water palaeoceanographic reconstructions as they can record environmental variation at sub-decadal resolution in locations where in-situ measurements lack temporal coverage. Yet, detailed three dimensional (3D) characterisations of bamboo coral skeletal architecture are not routinely available and non-destructive investigations into microscale variations in calcification are rare. Here, we provide high-resolution micro-focus computed tomography (µCT) data of skeletal density for two species of bamboo coral (Acanella arbuscula: 5 specimens, voxel size, 15 µm (central branch scans) and 50 µm (complete structure scan); Keratoisis sp.: 4 specimens, voxel size, 15 µm) collected from the Labrador Sea and Baffin Bay deep-water basins, Eastern Canadian Arctic. These data provide reference models useful for developing methods to assess structural integrity and other fine-scale complexities in many biological, geological, and industrial systems. This will be of wider value to those investigating structural composition, arrangement and/or composition of complex architecture within the fields and subdisciplines of biology, ecology, medicine, environmental geology, and structural engineering.
长寿竹珊瑚（Keratoisididae 科）的骨骼是深海古海洋重建的有前途的档案，因为它们可以在原位测量缺乏时间覆盖的地方以亚十年分辨率记录环境变化。然而，竹珊瑚骨骼结构的详细三维（3D）特征通常不可用，对钙化微尺度变化的非破坏性研究也很少。在这里，我们提供了来自拉布拉多海和巴芬湾深水盆地的两种竹珊瑚（Acanella arbuscula：5 个标本，体素大小为 15μm（中央分支扫描）和 50μm（完整结构扫描）；Keratoisis sp.：4 个标本，体素大小为 15μm）的骨骼密度高分辨率微焦点计算机断层扫描（µCT）数据。这些数据为评估许多生物、地质和工业系统中的结构完整性和其他细尺度复杂性的方法提供了参考模型。这将对那些在生物学、生态学、医学、环境地质学和结构工程等领域和子学科中研究复杂结构的组成、排列和/或组成的人具有更广泛的价值。
