Data on nephelometry, CTD probing, and dissolved manganese obtained during Cruise 34 of R/V Akademik Mstislav Keldysh showed that a multiplume was found over the Mid-Atlantic Ridge rift zone near 29°N. This multiplume comprises plumes of several hydrothermal vents and is separate from the plume of the Broken Spur hydrothermal field. Approximate coordinates were estimated for three vents.
