Short summary

Mangroves are key ecosystem for the global carbon cycle, yet the dynamics of dissolved organic matter in their soils must be better constrained. We investigated dissolved organic matter quality and quantity in porewaters of mangroves developing in a semi-arid region. The dominance of humic-like fluorescent component suggests that organic matter is primarily mangrove-derived. In addition, habitats and seasons seem to be the main drivers of dissolved organic matter dynamics.
