  abstract = {{S}hortly after strong rains or tropical storms, chlorophyll-a concentration ({C}hla), turbidity, and colored dissolved organic matter ({CDOM}) in the lagoon of {N}ew {C}aledonia may be tripled. {T}his effect is visible as far as 50 km offshore. {T}he {E}astern {C}oast of {N}ew {C}aledonia is more impacted than the {W}estern {C}oast because of its geomorphological structure. {H}igher frequency and intensity of the rains, and the dominance of highly erosive lateritic formations resulted from deep weathering of ultramafic rocks. {A}t the deeper parts of the lagoon (> 20 m), increases of {C}hla, turbidity, and {CDOM} absorption can be detected by satellite imagery with their plumes extending off shore as a result of wind-driven circulation in the lagoon. {S}uch increases agree with the oceanographic measurements of {C}hla, absorption, backscattering, turbidity and {CDOM} during extensive cruises. {S}atellite and in situ measurements allow tracing of particulates and dissolved matter in lagoon waters and up to the coral barrier reefs. {T}he largest particles settle at a short distance from the coast influencing the sediments not far from the river outflows. {F}ine particles (< 10 µm), colloids and/or {CDOM} are exported to reefs where they can be beneficial through protection from high {UV} illumination (colloids) and feeding of the corals ({CDOM}). {P}hytoplankton and associated detritus, when not dominated by toxic filamentous cyanobacteria, can also feed coral reefs. {F}inally, the export of fine particles associated with colloids and/or {CDOM} can also contribute to the distribution of trace metals to the barrier reefs of the {E}ast {C}oast and offshore. {T}he question whether this input of trace metals has an overall positive or negative effect on the coral reefs is still under debate.},
