  abstract = {{T}he impact of human activities on marine environments is poorly addressed by the scope of life cycle impact assessment ({LCIA}). {T}he aim of this study is to provide characterization factors to assess impacts of sea use such as fishing activities or seafloor destruction and transformation on the life support functions of marine ecosystems. {T}he consensual framework of land use for ecosystem services damage potential assessment was applied, according to the recent {U}nited {N}ations {E}nvironment {P}rogramme-{S}ociety for {E}nvironmental {T}oxicology and {C}hemistry ({UNEP}-{SETAC}) guidelines, using the free net primary production as a quality index of life support functions. {T}he impact of shading, biomass removal, seafloor destruction, and artificial habitat creation on the available quantity of organic biomass for the ecosystem functioning was quantified at the midpoint level with a common unit (kg of organic carbon equivalent). {I}t included effects of human interventions on both the ecosystem production potential and the stock of biomass present within the ecosystem. {C}haracterization factors ({CF}) for biomass removal vary from 0.1 kg({C}eq) kg(-1) for seaweed to 111.1 kg({C}eq) kg(-1) for tunas, bonitos, and billfishes. {CF} for seafloor destruction range from 0.164 kg({C}eq) m(-2) for a temperate seagrass ecosystem to 0.342 kg({C}eq) m(-2) for an intertidal tropical rocky habitat. {T}his study provides an operational method in order to compute sea use impact assessment.},
