Cross Section of Black Smoker Ridge (image) Norwegian University of Science and Technology Share Print E-Mail Caption This image shows a cross section of the region surveyed for the study, with the ultraslow-spreading ridge at the center. Arrows in the red areas at the top of the section show circulation patterns of seawater through the oceanic crust, which helps enrich the water with metals before it emerges from the ridge in a black smoker.
