摘要: The California Current System is characterized by upwelling and rich mesoscale eddy activity. Cyclonic eddies generally pinch off from meanders in the Current, potentially trapping upwelled water along coast transporting it offshore. Here, we use satellite-derived measurements of particulate organic carbon (POC) as a tracer coastal to show that cyclones located offshore were generated near contain higher concentrations their interior than same amplitude This indicates are fact offshore, resulting an POC enrichment 20.9 ± 11 Gg year−1. due coastally-generated extends for 1000 km shore. analysis provides large-scale observational-based evidence play quantitatively important role transport water, substantially widening area influenced highly productive waters System. wind-driven activity, ecosystem.
