To prevent the drilling mechanism from twisting while the bit stays still, a long bar is attached to the drill by a marine park ranger while another ranger holds the bit/mooring in position. The bar will be tied to an anchor (hand set in sand, of course) and supervised by a diver; the anchor rope and diver are partially visible at the right of the photo. Small head corals and gorgonian corals are visible on the bottom.
