Grabber

Purpose

Grabber (grab sampler with a TV control) for soil sampling at the ocean bottom with the depth of 250-6000m during geological, geotechnical and geo-environmental work.

  • Grabber provides:
    • sampling of bottom samples in the fields of ferromanganese nodules concretions (IMC) natural occurrence
    • sampling of samples, fragments of cobalt-nickel-rich crusts
    • sampling of heavy clays, sands
    • sampling control through PC monitor using TV cameras.
