  abstract = {{S}uspended and sedimented particulate materials were assessed monthly at five sites on the south-west lagoon of {N}ew {C}aledonia, from {M}ay 1986 to {A}pril 1987. {S}edimentation of particulate matter was measured using sediment traps for 24 h. {R}esuspension, which accounted for more than 80% of the total sedimentation, was distinguished to calculate net sedimentation values. {T}he mean net sedimentation rate for the lagoon varied according to the site from 0.481 to 1.157 g{C}/m2/day with a general mean value of 0.756 g{C}/m2/day. {A}n increasing gradient from the reef to the shore stations was observed for both suspended and sedimented particles. {T}he standing stocks and the fluxes of suspended particles were maximal in {F}ebruary, during the warm season associated with maximal rainfall, and minimal in {A}ugust. {T}he high {C}/{N} ratio in sedimented material compared to suspended particles indicated that organic matter degradation had occurred preferentially in the water column. {T}he mean particulate organic carbon flux was about twice the lagoon pelagic primary production ; sedimented plant material only accounted for a small part of the organic carbon flux. {T}he major source of sedimented organic carbon was therefore allochthonous and derived both from the reef and the shore. {T}he latter seemed to predominate. {R}elative uncoupling between benthos and pelagos is suggested.
