The purpose of television research is to verify the anomalies of the natural field (NF) potential , to identify and delineate the PS ore bodies and the zones of metalliferous deposits in ore fields, as well as visual signs of hydrothermal activity in areas promising for PS. An additional task of television profiling is to collect information on the status of benthic ecosystems.
TV research is carried out using the TV submersible (TVS) Sperre (Fig. 1, 1a) manufactured by "Sperre" (Norway), the grab DG-1 manufactured by "HYCO" (Fig. 2), the grab GK-6T manufactured by "HYCO" (Fig .3) instrumented with television equipment.
