Giant Crane Game for Sediment

What does the sediment look like on the bottom of the ocean?  The easiest way to get a sample is to send a giant sediment sampler (grabber) which is open as it drops to the seafloor, and closes when hits the bottom.  Then voila, the grabber is filled with sand or gravel from the ocean depths!  We can get an idea of how these sediments will move by how large or small the particles are.
