#WeekendReading: Greiffenhagen et al. on organic and inorganic carbon burial in cold-water coral mounds of the Alburan Sea. Would probably prefer to see a bit more stable isotope work on that one, but the results and approach still interesting. 🧪⚒️🌊

CT-image-based core section close-ups of the MeBo on-mound core GeoB18116-2 collected from Dragon Mound (left is the orthoslice; right is the 3D macrofossils' reconstruction: each coral fragment has an individual colour and the core depth is given in CSF-B metres below seafloor). (a) Hiatus covering a time span of ∼ 100 kyr between mound formation phases DM5 and DM6. The red arrow indicates the top of DM5 (coral ages ∼ MIS7b), followed by DM6 (coral ages ∼ MIS5d). (b) Example of a high-coral-carbonate-bearing unit during the mound formation phase, DM2 (MIS10, ∼ 350 kyr BP). (c) Scan of the mound base (61.1 m b.s.f.), including burrows filled with cold-water coral mound sediments (white outlines), the first cold-water coral clasts, and several oyster shells (blue arrow) from DM1 (∼ MIS11). Grey scale bars at the bottom represent ∼ 2 cm in length.
