Miles beneath the ocean’s surface in the dark abyss, vast communities of subseafloor microbes at deep-sea hot springs are converting chemicals into energy that allows deep-sea life to survive—and even thrive—in a world without sunlight. Until now, however, measuring the productivity of subseafloor microbe communities—or how fast they oxidize chemicals and the amount of carbon they produce—has been nearly impossible.

In 2017, Japan became the first country to test mining ocean minerals on a significant scale. While its operation took place at depths of about 1,600 metres, many deep seabed minerals are much deeper – more than four kilometres down. These are pitch-black environments in which pressures are bone-crushingly high, and life operates on a completely different timescale. At these depths, mistakes can be costly for both industry operators and the environment.
