- •
We report dissolved Mn and Fe observations in mangroves along a latitudinal gradient.
- •
Average Mn concentrations decreased at lower latitudes and were a function of intertidal area size.
- •
Mn concentrations were over one order of magnitude greater in porewaters than surface waters.
- •
Average dissolved Mn export rates from the four mangrove systems to the coastal ocean was 88,000 mol km− 2 year− 1.
- •
Up-scaled global estimated fluxes from mangrove were greater than both riverine and atmospheric sources
