Energetics of the deep-water bluntnose sixgill shark

Bluntnose sixgill shark

Deep sea sharks get less attention than their surface-loving counterparts.  Take for example the bluntnose sixgill shark (Hexanchus griseus).  At 16 feet in length, this shark is almost large as a white shark or a tiger shark, and the species has a wide global distribution.   H. griseus might be a top predator, but because he tends to be found up ...

An ecosystem-based approach to protect the deep sea from mining

Starfish in deep sea

Five hundred miles southeast of Hawai‘i, in international waters far out of sight of any land, there are vast mineral resources 5,000 meters below the sea. Manganese nodules, rich in commercially valuable mineral resources including nickel, copper, manganese, cobalt and rare-earth elements, overlay a broad swath of the deep-sea floor. It took millions of years to form these deposits. The ...
