A mining robot is stuck on the Pacific Ocean floor.
The robot is currently stuck at a 4km depth after becoming detached during a trial.
The Belgian mining company has been testing Patania II, a 25-tonne mining robot prototype since April 20.
The machine is meant to collect sea floor samples and was connected to their ship with a 5km cable.
The plan was to analyse data and samples collected by the robot in order to measure the impact of seabed mining.
The Belgian company has said it will apply for a mining contract if the science shows deep seabed minerals have advantages and the damage is limited.
