MeBo-Core GeoB18116-2 is a unique record, documenting the complete development of a 60 m high cold-water coral mound in the East Melilla Coral Mound Province, Alborán Sea, Western Mediterranean. Density data were obtained with Pycnometer measurements following OPD standards CT mean x-ray attenuation data from the same core depth are presented as well, since they can be used as a proxy for sediment density, and show a good correlation for this core. This contributes to a multi-step analysis of the core with the aim to calculate the total carbon accumulation within the coral mound.
