  abstract = {{V}ariations of the sticking properties of transparent exopolymeric particles ({TEP}) were investigated by studying the interactions between latex beads and {TEP} precursors collected along a salinity gradient in the {B}ach {D}ang estuary, {N}orth {V}ietnam. {F}or each sampling station, a suspension of {TEP} and beads was prepared and the formation of mixed aggregates was monitored in the laboratory under controlled turbulence intensity. {T}he number of beads attached to {TEP} per volume of {TEP} increased from 0.22 x 10(-3) +/- 0.15 x 10(-3) mu m(-3) to 5.33 x 10(-3) +/- 1.61 x 10(-3) mu m(-3), from low (<1) to high (>28) salinities, respectively. {T}he sudden increase in {TEP} sticking properties from salinity 10 to 15 suggests the occurrence of an "aggregation web" resulting from the stimulation of aggregation processes. {F}or a given turbulence level, the formation of large aggregates should be enhanced seaward. {T}he presence of a higher fraction of large aggregates seaward is supported by the increase of the slope of the particle size spectra measured in situ. {T}he observed increase in {TEP} sticking properties toward high salinities may affect the vertical export pump in estuaries. {T}his study suggests that the transition from a low to a high physico-chemical reactivity of {TEP} along estuaries may result in a succession from recycling for salinity <10 to enhanced aggregation/sedimentation processes and export dominated systems for salinity >10.},
