  abstract = {{B}lack carbon ({BC}) is emitted to the atmosphere during biomass, biofuel, and fossil fuel combustion, and leaves the atmosphere via dry or wet deposition on land and on the ocean. {O}n a global scale, wet deposition accounts for about 80% of the total atmospheric {BC} inputs to the ocean. {T}he input of {BC} particles to the ocean can enrich surface waters with carbon and associated elements, and owing to high porosity and surface-active properties, {BC} can alter biogeochemical cycles by sorbing dissolved compounds and promoting aggregation. {T}he rain-mediated input of {BC} to the ocean and its consequences on nutrient concentrations and particle dynamics were studied in {H}along {B}ay, {V}ietnam, during a 24-h cycle impacted by short and heavy rainfall events. {T}his study suggests that once introduced in the surface ocean via wet deposition, {BC} sorbs dissolved organic matter ({DOM}) and stimulates aggregation processes. {T}he observed wet deposition events were characterized by sudden and pulsed inputs of {BC} particles that created a thin layer of sinking surface-active aggregates, acting as a net-like scavenger for {DOM}, nutrients (especially phosphate), and small particles. {I}n addition, the wet deposition events coincided with an enrichment of nutrients in the surface microlayer, with an excess input of nitrogen relative to phosphorus leading to an increase of the molar {N}:{P} ratio from 24:1 to 37:1. {I}n the underlying water, the molar {N}: {P} ratio also increased (i.e., from 39:1 to 64:1), and this can be attributed to the preferential scavenging of dissolved {P}-compounds on sinking {BC}-aggregates.},
