  abstract = {{T}his paper presents the concentration and size distribution of suspended particles in the {S}outh-{W}est {C}oral reef lagoon of the island of {N}ew {C}aledonia. {D}ata are provided by filtration techniques, {O}ptical {B}ack{S}cattering ({OBS}) measurements and in situ laser diffraction particle sizing. {T}he concentration of suspended particles increased from reef to land. {A} bottom nepheloid layer occurred over the entire lagoon. and was more distinct on the nearshore area. {S}mall particles were more abundant in the bottom nepheloid layer than in the overlying water column. {T}he concentration of suspended particles showed more variability over space than over time. {C}onversely. the particle size distribution of suspended particles showed more variability at a given location over a month (time variability) than at a given moment over the lagoon (space variability). {A}nalysis showed that aggregates represented a large fraction of suspended particles. {M}icroscope visualization and chemical analysis of a sample suggest the inclusion of a transparent exopolymeric matrix. {T}he relative abundance of aggregates over suspended particle volume concentration was found to increase as tire quantity of suspended particle decreased. {T}he spatial distribution of the relative abundance of aggregates suggests more aggregates proximal to coral reefs. {T}he high concentration of aggregates at low turbidity and the spatial distribution of the relative abundance, infer that aggregation is induced by the presence of organic ligands. {U}nlike optical backscattering and light attenuation measurements that are size sensitive measurements of suspended particle concentration, in situ laser diffraction particle sizing provides a relevant optical measurement of suspended particulate matter in such an aggregate-dominated system.},
