Origins and budget of manganese in Mn-microparticles in oxic pelagic sediments. ad Depth profiles of mass and proportion of manganese in Mn-microparticles in sediment samples: a average mass of major elements in a Mn-microparticle; b average mass of manganese in Mn-microparticles in a unit volume of sample; c major-element composition of the bulk sample21; and d proportion of Mn-microparticle manganese mass to bulk sample mass. e Fe–Mn–(Co + Cu + Ni) × 10 ternary diagram22 for the Mn-microparticles. f Comparison of the manganese budgets estimated for Mn-nodules and crusts on the seafloor20, Mn-microparticles in oxic pelagic clay, and a bulk sample of oxic pelagic clay21. Whiskers represent maximum and minimum estimates
