Mapping 25 Years of Micronekton Dynamics Across Changing Ocean Provinces

Micronekton are marine organisms gathering a wide diversity of taxa (crustaceans, fish, cephalopods) 2 to 20 cm in size. They are responsible for an important carbon export to the deep ocean and are the main prey for marine predators. We define provinces of homogeneous environmental parameters, representing areas of common micronekton biomass and vertical structure. We observe the evolution of the provinces in time from 1998 to 2023 to account for the seasonal to interannual variability.
