Figure 10. A Van Veen grab sampling device awaits deployment on the deck of the OSV Bold. The sampler is weighted and within a metal frame that is lowered to the seafloor by a cable on a winch. In the center are two open metal parts that close, much like a clam shell, to grab a sample of sediment on the seafloor. The sample is brought back on deck and transferred to bags for later analysis.
