Notes on Vent Field Description:
Bougault et al. (1998), referring to the 1973-74 FAMOUS project: "A silicate hydrothermal deposit was sampled by the diving saucer Cyana in the transform fault north of the FAMOUS segment near 37°N (not in the inner floor of the rift valley) "; depth is approximate based on Fig. 1 in Bougault et al. (1998)
