Co-lead author of 788-species study

A five-year research expedition has cataloged 788 species living 4,000 meters beneath the Pacific Ocean—90% of them previously unknown to science—just as the race to mine the same seabed accelerates. The study, published in February 2026, documents a 37% decline in animal abundance wherever mining equipment touched the seafloor. It's the first systematic look at what commercial extraction would destroy.
