Deep sea surveys detect over five thousand new species in future mining hotspot

There is a massive, mineral-rich region in the Pacific Ocean — about twice the size of India — called the Clarion-Clipperton Zone (CCZ), which has already been divided up and assigned to companies for future deep-sea mining. To better understand what may be at risk once companies start mining, a team of biologists has built the first ‘CCZ checklist’ by compiling all the species records from previous research expeditions to the region. Their estimates of the species diversity of the CCZ included a total of 5,578 different species, an estimated 88% – 92% of which are entirely new to science.
