Notes on Vent Field Description:
Fe & Mn oxide mounds with abundant Fe silicate (nontronite) deposits, off-axis hydrothermal mounds; Williams et al. (1979): "internal temperatures have been measured at up to 13°C above the bottom water temperature,"; Corliss et al. (1979): "a visual flow of water with temperatures between 4 and 10 C was initiated by punching holes through the crusts on the mound surfaces" with Alvin

Year and How Discovered (if active, visual confirmation is listed first):
