The Slurry of Seafloor Sediment

The title ‘Slurry of Seafloor Sediment' speaks to slurping up of precious, million-year-old polymetallic nodules from the deep sea. When the nodules are collected near the ocean surface the sediment waste will be discharged back into the sea, drifting for miles, with fears of major environmental impact to the ocean columns. My aim is for this painting to help raise awareness about the risk of exploiting this last frontier.


I learned about this concept, the ‘Common Heritage of Mankind’ in a Speak up for Blue podcast with guest speaker Dr. Diva Amon. In summary, no one person or country has jurisdiction over an area (be it seafloor or outer space) and the resources extracted in this area should be arranged to benefit humankind as a whole, including all future generations to come. Currently, the International Seabed Authority has granted 16 open contracts for mining investors in the Clarion Clipperton Zone, located in the Northern Pacific. However, researchers are trying to understand the full implications of extraction in this area. We have an imperative need for international governing bodies to determine what level of impact is acceptable to society.
