Maganese nodule

This work has been inspired by two images linked to the current debates on deep-sea mining. 

It requires millions of years of continuous chemical reactions to form the potato-shaped nodules spreading over the abyssal plain.  Scientific discovery has shown a universe of biological diversity in the depths, contrary to what we previously assumed.  The animals attached to this metallic nodule are a perfect example for us to reflect on our connection to the deep sea.
