Sequestration efficiency in the iron-limited North Atlantic: Implications for iron supply mode to fertilized blooms
Abstract Estimates of the amount of carbon sequestered in the ocean interior per unit iron (Fe) supplied, as quantified by the sequestration efficiency (Ceffx), vary widely. Such variability in Ceffx has frequently been attributed to estimate uncertainty rather than intrinsic variability. Here we de...
