THE LIGHT POST In a painting of a hydrothermal chimney named Hulk on the Juan de Fuca Ridge, a camera mounted on the remotely operated vehicle Jason 2 captures high-resolution images using light from the deep-sea light post. The light post?s light is about 20 times more powerful than the average 60-watt household bulb. (Illustration by E. Paul Oberlander, Woods Hole Oceanographic Institution)
