Abstract:
This publication considers data on aquatic anomalies (hydrothermal plumes) in the areas of 26° and 29°N of the Mid-Atlantic Ridge (MAR). Mass of hydrothermal iron supply and intensity of iron sedimentation onto the bottom were estimated by means of sediment traps. It was found that the plume of the TAG hydrothermal vent 6 km**3 in volume contained about 67 tons of particulate Fe; the plume of the Broken Spur field (up to 8.24 km**3 in volume) contained 23.5 tons of particulate Fe or less because of its lower concentration. Data on sediment matter fluxes showed that 0.3-0.5% of hydrothermal iron was precipitated immediately from the neutrally buoyant plume onto the bottom; the bulk of iron was dissipated into environment. From dimensions of the plumes, flow dynamics, iron concentrations in the plumes, and amounts of iron supplied by hydrothermal vents, it was found that resident time of the plumes considered was from 5 to 10 days.
