Short summary
Short summary
From 2014 to 2021, extensive monitoring of hydrodynamics was deployed within five contrasted lagoons of New Caledonia during austral summers. These coastal physical observations encompassed unmonitored lagoons and captured eight major atmospheric events ranging from tropical depression to category 4 cyclone. The main objectives were to characterize the processes controlling hydrodynamics of these lagoons and record the signature of extreme events on land–lagoon–ocean continuum functioning.

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.
