How many species live in the world’s largest marine mineral exploration region?

This study offers the first comprehensive synthesis of published data for the Clarion-Clipperton Zone (CCZ) in the central and eastern Pacific. The authors report that this area, which covers 6 million km2, represents significant undescribed biodiversity with an estimated 88%–92% species waiting to be described. Data used in this research were extracted from OBIS highlighting its value as a global data repository for marine biodiversity.
