Diatom communities trapped within CCS mesoscale eddies evolve in response to environmental shifts as they travel offshore. The high nutrients in coastal waters are drawn down over time by coastal diatoms with higher nutrient requirements, leaving behind low-nutrient waters suitable for oceanic diatoms and diatoms with low-nutrient adaptations. The combined effect of transport by, and ecological succession within the eddies is likely a key factor in mediating carbon cycling and export across the wider CCS region.
