Data sets

The polychaete fauna of the Clarion-Clipperton Fracture Zone from boxcore samples during SONNE cruise SO239 P. Bonifácio, L. Neal, E. Omnes, B. François, T. G. Dahlgren, and L. Menot

Polychaete sequences from Clarion-Clipperton Fracture Zone sampled with box-corer during SONNE cruise SO239, BOLD P. Bonifácio

Short summary
The patterns observed in the composition of polychaete assemblages were attributed to variations in food supply at the regional scale and nodule density at the local scale. The high levels of species replacement were mainly driven by rare species, leading to regional species pool estimates between 498 and 240 000 species. The high proportion of singletons seems reflect an under-sampling bias that is currently preventing the assessment of potential biodiversity loss due to nodule mining.
