High-resolution three-dimensional images of deep-sea bamboo corals Acanella arbuscula and Keratoisis sp. collected in the Baffin Bay and Davis Strait during the CCGS Amundsen expedition in 2021

High-resolution X-ray computed tomography images of two deep-sea bamboo corals (Acanella arbuscula, Johnson, 1862; Keratoisis sp., Wright, 1869) collected from Baffin Bay and Davis Strait during a research expedition on board the CCGS Amundsen in July-August 2021. Corals were imaged using Micro-Focused X-Ray Computed Tomography at the Micro-Vis X-ray Imaging Centre (Southampton, UK) to non-destructively investigate their skeletal architecture, calcification strategies and growth patterns.

Statement

Coral specimens were securely positioned vertically in Perspex holding tubes with polystyrene bungs to ensure stability during rotation and scanning.

A water tube was also scanned under the same conditions as the samples to serve as a density reference. CT Pro 3D 6.6 or 6.7 software (Nikon Xtek, Tring UK) was used for all reconstructions.

During concatenation of separate scans, image contrast was adjusted to compensate for any heel effect in the absence of density calibration.

Conversion to stacked tagged image file format (TIFF) images was lossless.
