NOAA Photo Library Image - expl1578

Ring of Fire 2002 Expedition. A small segment of midocean ridge crest showing the development of hydrothermal plumes. Plumes issue from small sites on the ridge crest, often as a result of an intrusion of a magma dike during an episode of seafloor spreading. The hot fluids rise and grow increasingly diluted by the surrounding seawater and get swept away by local bottom currents.
