Ramping up for REMPs: An introduction to Regional Environmental Management Plans.

As deep-sea mining creeps towards production and the International Seabed Authority works diligently to produce a comprehensive Mining Code for exploitation in the Area, stakeholders from across the spectrum are racing to answer one question: how do we predict, assess, manage, and mitigate environmental harm in the deep sea beyond national jurisdiction? Increasingly, regulators, contractors, […]

A Primer on Seafloor Massive Sulphides

Formed at the margins where tectonic plates collide or diverge, seafloor massive sulphides are the most geologically active and among the most metal-rich deep-sea deposits. Only discovered in 1977 (though there were some tantalizing near misses several decades earlier), exploration on these prospects is relatively immature compared to formations like polymetallic nodule fields, which have […]

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.  […]

“We need to make choices based on evidence”: an interview with GSR managing director Kris Van Nijen

Maria Bolevich for DSM Observer Global Sea Mineral Resources (GSR) is founded by Deme Group, a world leader in dredging, marine engineering and environmental remediation. In 2013, GSR and the International Seabed Authority entered into a 15-year contract for the exploration for polymetallic nodules in the Clarion-Clipperton Zone. Kris Van Nijen, the managing director of GSR, […]

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 […]
