The biogeochemical scavenging of dissolved manganese (Mn) from hydrothermal plumes was investigated using radiotracer (54 Mn) techniques.The measured scavenging rate constant, k 1, was lowest in the buoyant plume (<0.2 y −1), increasing to ∼2 y −1 in the non-buoyant plume at distances of 20 km from the ridge valley axis. The direct biological contribution to the dissolved Mn scavenging ...
