A lost continent rich in cobalt crusts could create a challenging precedent for mineral extraction in the high seas.

The Rio Grande Rise is an almost completely unstudied, geologically intriguing, ecologically mysterious, potential lost continent in the deep south Atlantic. And it also hosts dense cobalt-rich crusts. The Rio Grande Rise is a region of deep-ocean seamounts roughly the area of Iceland in the southwestern Atlantic. It lies west of the Mid-Atlantic Ridge off […]

The International Seabed Authority and Deep Seabed Mining

MICHAEL LODGE in UN CHRONICLE | May 2017 “The deep ocean below 200 metres is the largest habitat for life on Earth and the most difficult to access. The sea floor, just like the terrestrial environment, is made up of mountain ranges, plateaus, volcanic peaks, canyons and vast abyssal plains. It contains most of the […]

Subsea mining moves closer to shore

HELMHOLTZ CENTRE FOR OCEAN RESEARCH KIEL (GEOMAR) | 9 February 2017 The demand for raw materials is rising continuously, forcing mining companies to use lower-grade ores and to explore at greater depths. This could lead to a decline in production in the coming decades. Many industrialized economies also depend on imports of metals for their […]
