  abstract = {{W}ith hull-mounted multibeam echosounder data, we report for the first time along the active {E}cuadorian margin, acoustic signatures of water column fluid emissions and seep-related structures on the seafloor. {I}n total 17 flare-shaped acoustic anomalies were detected from the upper slope (1250 m) to the shelf break (140 m). {N}early half of the flare-shaped acoustic anomalies rise 200-500 m above the seafloor. {T}he base of the flares is generally associated with high-reflectivity backscatter patches contrasting with the neighboring seafloor. {W}e interpret these flares as caused by fluid escape in the water column, most likely gases. {H}igh-resolution seismic profiles show that most flares occur close to the surface expression of active faults, deformed areas, slope instabilities or diapiric structures. {I}n two areas tectonic deformation disrupts a {B}ottom {S}imulating {R}eflector ({BSR}), suggesting that buried frozen gas hydrates are destabilized, thus supplying free gas emissions and related flares. {T}his discovery is important as it opens the way to determine the nature and origin of the emitted fluids and their potential link with the hydrocarbon system of the forearc basins along the {E}cuadorian margin.},
