Figure 2 - There is an almost complete absence of published, databased benthic species records from the Clarion-Clipperton Zone (CCZ), despite over 30 years of intensive oceanographic and geological research in the area. Here illustrated as an example are the current species records for a 300,000 km2 (5°) box centred on the North Sea and Eastern Channel in Europe, where the Ocean Biogeographic Information System (OBIS 2016) provides 182,939 records of polychaetes, a common benthic animal in all oceans. By contrast, the same size box centered on the eastern CCZ provides just 4 polychaete records, none of which are benthic.
