Although we use the magnetometer and the multibeam echosounder, we do in the end need to get our hands on some of the rocks from the ocean floor.\u00a0 We do this in a truly ancient way, using a steel dredge dragged behind the ship.\u00a0 The dredge has a big wire basket for collecting the rocks and is pulled by a strong wire cable that leads up to the ship.\u00a0 The water is usually 1 to 3 miles deep and the rocks usually rough and strong. We need to get the dredge in the right place, drag it along slowly, pull hard enough to break off some rock and then bring it back up to the ship.\u00a0 It may be bulging full, or may contain just a few cobbles (of great interest) or may be empty.\u00a0 Usually somewhere in between.<\/p>\n
