One of the most significant deep-sea mining negotiations is underway at the Commission on the Limits of the Continental Shelf

One of the most significant discussions in deep-sea mining is happening not a the International Seabed Authority, but in the offices of the Commission on the Limits of the Continental Shelf at the United Nations’ headquarters in New York. The CLCS is responsible for assessing outer continental shelf claims, those portions of a nation’s continental […]

A Primer on Cobalt-rich Crusts

Scattered throughout the ocean are thick, metal-rich crusts that grow slowly on the exposed sides of seamounts. Among the three major ore types that are the predominant focus of deep-sea mining, these cobalt-rich crusts have received the least attention. While polymetallic nodules have occupied the deep-sea mining community’s collective imagination since the genesis of the […]

A watershed summer for electric vehicles

Electric vehicles made a huge splash this summer, with nearly every major car manufacturer announcing a new line of all-electric, hybrid, or plug-in hybrid vehicles. Battery manufacturers announced huge leaps in production. And major shipping companies declared new commitments to electrifying their fleets while nations set ambitious targets for transitioning away from internal combustion engines.  […]

As always, the Earth Negotiations Bulletin has provided a comprehensive summary of the overall meeting as well as day-to-day […]

Deep-sea mining and the future: Students share their experience as first-time observers at the ISA

Being deep-sea scientists is all about wandering into the unknown, strongly driven by our research motivations. Some people say that life is all about opportunities, and for us the opportunity to attend the Council meeting at 2nd part of the ISA Annual Session was one of those life changing experiences, a reinforcement of our passion […]

A big-hearted iron snail is the first deep-sea species to be declared endangered due to seabed mining.

In 2001, on an expedition to hydrothermal vent fields in the Indian Ocean, researchers made a bizarre discovery. Clustered in small aggregations around the base of a black smoker was an unusual snail, seemingly clad in a suit of armor. Rather than a single, hard, calcareous structure, the snail’s operculum was covered in a series […]

From the Editor: US Mineral Policy and an atomic legacy.

Last year, for a completely unrelated project, I conducted a census of how many nuclear weapons had been lost at sea. Since then, I haven’t been able to stop thinking about the interplay between military, scientific, and commercial use of the high seas, as well as, perhaps, the most improbable question of all: what happens […]
