REMPs and the Ecosystem Approach: lessons from the Évora workshop

Maila Guilhon for the Deep-sea Mining Observer In 2007, scientists first convened a workshop to discuss conservation measures in the Clarion-Clipperton Zone, leading ultimately to the establishment of the first Environmental Management Plan for mining in the Area. Now, evaluating and establishing Regional Environmental Management Plans (REMPs) are  a significant component of deep-sea mining discussions. […]

A Primer on Polymetallic Nodule Fields

Scattered across the abyssal plain at depths from 4000 to 6500 meters, polymetallic nodules are the most abundant and broadly distributed of the three major ore types currently being pursued by deep-sea mining companies. Originally referred to as manganese nodules, this small, potato-sized accretions on the seafloor were first discovered during the Challenger Expedition in […]

Solid state batteries could change the seascape for deep-sea mining

In 1980, Dr. John B. Goodenough unraveled the electro-chemical reactions that would give birth to one of the single most important inventions of the 20th century: the lithium ion battery. The first commercially viable rechargeable lithium ion batteries were soon being produced by Dr. Akira Yoshino at Sony. Without these tiny cells’ immense potential to […]
