Young grab

It is a modified version of the Van Veen grab sampler, with a clamshell bucket made out of stainless steel mounted to a supporting frame.

The sampling area extracted with this instrument can vary depending on its size.

Weights can be attached to the frame to ensure the bucket grabs sufficient sediment, or skids to ensure the gear does not sink too deep in soft sediments.

While letting the instrument down into the water, the two levers with buckets at their ends are spread like an open scissor.

When the rope is pulled upward again, the two buckets close and grab a sample from the sea floor.
