Global maps of the Ocean microbiome: Taxonomic and functional diversity of copepods in surface waters (0-10 m), available as monthly climatologies projected under contemporary (2012–2031) and future, end-of-century (2081–2100) environmental conditions, u…

This collection of global maps provides global gridded estimates of the functional diversity (FD) of marine copepod assemblages. FD indices were estimated by combining species distribution models (SDMs) with species-level functional traits (i.e., body size, trophic group, feeding mode, myelination and spawning mode) for > 300 copepod species. The dataset includes two complementary products: a contemporary baseline representing average copepod FD patterns for the present-day ocean and a future projection representing expected end-of-century (2081–2100) average changes in FD under a high-emission climate scenario (RCP8.5). Both products are provided as monthly climatologies at 1° × 1° spatial resolution for the surface ocean (0–10 m). Multiple FD indices were computed to cover multiple aspects of functional diversity including: functional richness, evenness, divergence, dispersion, and trait dissimilarity. These data allow researchers to investigate how copepod trait composition is structured across the global ocean today, and how it may be reshuffled in response to anthropogenic climate change. This dataset offers a valuable resource to assess potential impacts of changing zooplankton communities on marine productivity, carbon cycling, and climate feedbacks.
