The ROPOS manipulator arm prepares to sample an inactive chimney. The yellow color is caused by the alteration of iron-rich minerals, and the black outer crust is primarily manganese. This image was taken by the new underwater high-resolution digital camera on ROPOS. Image courtesy of Submarine Ring of Fire 2002, NOAA/OER.
