Maganese nodule

This work has been inspired by two images over the current debates on deep-sea mining.  It requires million of years of continuous chemical reactions to form the potato-shaped nodules spreading over the abyssal plain.  Contrary to what we assumed previously, the scientific discovery have shown an universe of biological diversity down there.  The animals attached to the this metallic nodule is a perfect example for us to reflect on our connection to the deep sea.
