What does this research mean for the field?

Mesoscale oceanographic variability, specifically the longitudinal gradient from productive upwelling to oligotrophic conditions, shapes the abundance, biomass, and trophic structure of mesozooplankton communities across the Canary Islands archipelago. Novelty: ClaimNovelty.NOVEL_FINDING. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Overview

Observational study reveals oceanographic gradients shape mesozooplankton trophic structure across an archipelago, highlighting environmental drivers of subtropical marine food webs.

Key Points

To assess mesozooplankton community composition, biomass, and trophic structure along a longitudinal environmental gradient in a subtropical oceanic archipelago.
Collected mesozooplankton samples during the ATLANTIS 2024 research cruise across the Canary Islands archipelago in the Central Eastern Atlantic.
Conducted stable isotope analyses (δ13C, δ15N, δ34S) alongside physical–biogeochemical satellite monitoring and multivariate statistical analysis.
Sea surface temperature increased westward from 15 to 24 °C, while chlorophyll-a concentrations decreased from 1.0 to <0.1 mg m−3, reflecting an environmental shift from productive upwelling waters to oligotrophic open-ocean conditions.
Zooplankton biomass and abundance were higher in the eastern sector, where enriched δ15N values indicated spatial variability in resource use and regional isotopic baseline conditions.
