Colossal Advancements in Accessible Deep-Ocean Technology

Accessing the deep seafloor is no small feat. Nations, institutions, contractors, and corporations make major capital investment into the tools and machines needed to explore and, ultimately, exploit the deep ocean. The enormous costs involved in deploying even basic equipment in 6000 meters of water has been among the biggest limiting factors in the development […]

Global Sea Mineral Resources unveils the Patania II nodule collector

This week, Global Sea Mineral Resources unveiled Patania II, a pre-prototype polymetallic nodule collector built to work in the Clarion-Clipperton Fracture Zone. Patania II is the successor to Patania I, which was successfully tested in the Central Pacific Ocean last year. Patania I was a track system designed to crawl across the deep seafloor of […]

The rise of low-cost ROVs and community submersibles

As a community, we discuss mining, management, and monitoring, as well as the regulations that shape them, in terms of governments, major corporations, and research institutions. The deep-sea mining community is small and the complexities of working at abyssal depths engenders collaboration, cooperation, and, in the case of exploitation, compromise. While there are many stakeholders […]

New Mineral-Sensing Technology Accelerates Ore Sorting

A new technology may accelerate ore sorting by illuminating batches of ore with short pulses of radio waves, assessing ore grade and enabling high tonnage sorting at rates of up to 5,000 tons per hour.  The technology uses sensors to sees through large ore batches in real time as they pass through an open-ended chamber. […]
