  abstract = {{M}icronekton are the mid-trophic level of the ecosystem and contribute to active carbon export to the deep ocean through diel vertical migrations. {B}etter characterization of micronekton functional groups depending on relationships to environmental variables is useful for the management of marine resources, the conservation of biodiversity and a better understanding of climate change impacts. {F}or this purpose, regionalization of global ocean into homogeneous provinces is an approach that is generating increasing interest. {H}owever, published regionalizations efforts (i) derived from environmental forcings, that do not specifically focus on micronekton and (ii) derived from acoustic backscatter, which do not allow direct estimates of micronekton biomass. {H}ere, we propose to fill the gap between biophysical regionalizations and micronekton biomass. {W}e notably defined biophysical biomes using global environmental variables known to affect micronekton: temperature of the epipelagic layer, temperature stratification, and net primary production ({NPP}). {S}ix biophysical biomes were defined with a clustering method. {A} characterization of these biophysical biomes with simulated micronekton from the {SEAPODYM}-{LMTL} model displayed biome-specific relationships between biomass and the environmental variables used in the clustering (i.e. biomasses mostly structured by {NPP} and temperature). {B}iophysical biomes also displayed specific vertical structures suggested by modelled micronekton functional groups ratios. {T}hen, a validation of biophysical biomes' boundaries was performed to identify potential vertical structure reorganization in acoustic backscattering response from adjacent biomes. {T}he regionalization identified homogeneous areas in terms of acoustic vertical structure, which were also different between adjacent biomes. {F}inally, a comparison with another biomes' definition computed from micronekton biomasses suggested that environmental variables can account for only some of the variability of the micronekton structures.},
