Said data is used to electronically control the immersion speed of the lost cast nest into the cooling medium.

Alternatively, the speed of the multi-tiered, spiral path conveyor belt can be adjusted to increase or decrease the rate of immersion of the materials or products into the cooling fluid.

Emergency conditions monitored include out-of-range, anti-tampering, panic alert, immersion and breathing rate, as well as other selected emergency or status conditions.

A theoretical approach to the immersion velocity of a probe is also proposed, as well as a presentation of some results of bathymetric surveys and physical observations made by the Challenger scientists.
