  abstract = {{T}he strong proliferation of holopelagic {S}argassum in the {T}ropical {A}tlantic from 2011, raises many questions on the environmental factors controlling their growth and decay at interannual, seasonal, and intraseasonal scales. {I}n this work, we specifically investigate the response of the {S}argassum aggregations to high wind events such as those found in {T}ropical {C}yclones ({TC}s). {T}he evolution of {S}argassum coverage obtained from {MODIS} observations in the north tropical {A}tlantic {O}cean (from 0 to 30 degrees {N} and from 0 to 100 degrees {W}) was analyzed under 86 historical paths of {TC}s and tropical storms from 2011 to 2020 that crossed {S}argassum aggregations. {O}ur results show on average a 40% drop in {S}argassum coverage under {TC} trajectories, which can exceed 60% for the most intense {TC}s. {W}e associate this drop with a sinking of {S}argassum toward the deep ocean. {O}ur estimates suggest that {TC}s contribute to the seasonal decay of {S}argassum biomass from {A}ugust to {N}ovember.},
