Titanic sub could be in ultra-deep water

The search for Titan is proving difficult.

The submersible could be in ultra-deep water as it is capable of reaching a depth of 4,000m – enough to reach the Titanic wreck which lies at 3,800m beneath the surface.

Radio and GPS signals can’t travel through water, therefore remotely operated vehicles (ROV) are being used for the search instead.

The French submersible Victor 6000, which is being used at this stage, is capable of reaching the sea bed and transmitting images to the surface as well as carrying out extremely delicate manoeuvres such as cutting or removing debris.
