Short summary
The Benguela Upwelling System hosts highly productive marine ecosystems, supporting the livelihood of the local inhabitants. Regional distribution of nutrients in this system is affected by upwelling, primarily wind-driven and related to the South Atlantic Anticyclone, which is believed to intensify in the future. We found that this system's southern and northern parts respond to the anticyclone changes differently. Due to climate variability, the uncertainty in the upwelling trend is high.
