Mining the Ocean Floor is Good!

The Mining Journal reports on statements by Nautilus representatives at the Numis Mining Conference with respect to criticism levied in Science.

Norgate argued that the high percentage of copper in the seabed surrounding Papua New Guinea would mean that less ‘land’ would need to be disturbed to generate the same amount of copper as open cut mining. She also said that water that was brought in during the dredging process would be purified before the water was returned to the ocean, preventing toxic pollution from entering the ecosystem.

Craig McClain is the Assistant Director of Science for the National Evolutionary Synthesis Center, a National Science Foundation supported initiative. He has conducted deep-sea research for 20 years and published over 50 papers in the area. He has participated in and led dozens of oceanographic expeditions taken him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig’s research focuses on how energy drives the biology of marine invertebrates from individuals to ecosystems, specifically, seeking to uncover how organisms are adapted to different levels of carbon availability, i.e. food, and how this determines the kinds and number of species in different parts of the oceans. Craig’s research has been featured on National Public Radio, Discovery Channel, Fox News, National Geographic and ABC News. In addition to his scientific research, Craig also advocates the need for scientists to connect with the public and is the founder and chief editor of the acclaimed Deep-Sea News (, a popular ocean-themed blog that has won numerous awards. His writing has been featured in Cosmos, Science Illustrated, American Scientist, Wired, Mental Floss, and the Open Lab: The Best Science Writing on the Web. His forthcoming book, Science of the South (, connects cultural icons of South such as pecan pie with the science behind them.

  1. If industry could be trusted to ensure no pollution one could
    agree with their attempts to recover copper ore etc. However, over the last fifty years industry has made many promises and assurances as they have systematically poisoned the world for a few fast bucks and the environment plus the people have ended up paying for it with their health, food supplies and massive environmental damage.

    I would therefore suggest that before any permission is granted, that they have insure against pollution so that they have to pay for the clean up, not the taxpayer to protect their profits!
