  abstract = {{M}icronekton are mid-trophic marine organisms characterized by a size range of 2 to 20 cm, gathering a wide diversity of taxa (crustaceans, fish, molluscs). {T}hey are responsible for an important active carbon export to the deep ocean because of their diel vertical migrations and constitute the main prey for pelagic predators. {A} new method has been proposed in the literature to define provinces that identify micronekton functioning patterns based on environmental variables. {F}ollowing this methodology, we define homogeneous provinces using environmental variables





computed from {C}opernicus {M}arine {S}ervice products. {T}hese provinces represent a relevant way to define regions of interest, offering a regional scope of study for micronekton indicators and their evolution in time. {I}n this study, we observe the evolution of the provinces in time from 1998 to 2023 to account for the decadal to climatic variability. {W}e focus on the variations in surface area and average latitude of each province. {W}e observe a global shrinking of productive provinces and polar provinces in favour of equatorial and tropical provinces' expansion. {A}dditionally, tracking





the geographical changes in the provinces over time shows that most are shifting toward the poles.},
