Quantifying aggregation bias in marsh carbon flux estimates caused by rhizosphere oxygen heterogeneity

Oxygen (O 2 ) in marsh rhizospheres varies strongly at millimetre scales due to radial oxygen loss (ROL), re-oxidation of reduced compounds, hydrology, and sediment structure. Yet many models estimate heterotrophic (microbial) respiration at a single mean O 2 , which can bias CO...
