4. Here we use a process-rich ocean biogeochemical model with validated representations of marine biodiversity and biogeochemistry5 to quantify fertilization potential and ecosystem impact across ten ocean biomes over 60years. We find regional disparities in climate ecosystem trade-offs: biomes with comparable CDR efficiency have contrasting ecological outcomes. The Southern Ocean and the equatorial Pacific achieve the highest efficiencies through distinct pathways: the former through non-local downstream carbon export,后者则通过局域输出但伴随下游损失,南大洋和赤道太平洋通过不同途径实现了最高效率:前者通过非局域的下游碳输出。

IssueVolume: 2026-07-29 Abstract: Ocean iron fertilization (OIF) is being discussed as a potential carbon dioxide removal (CDR) strategy1. Yet the trade-offs between climate benefits and ecological costs remain poorly understood2。

并降低了大型浮游动物生物量。

这些生态系统影响可通过将部署地点转移至高纬度地区来避免,其生态结果却截然不同,60年的施肥产生净CDR为1.15.3 ppm, Michaels, Francois W., Randerson, expands oxygen-minimum zones (OMZs) and reduces macrozooplankton biomass. These ecosystem impacts are potentially avoidable by shifting deployment to higher latitudes. Post-fertilization recovery experiments reveal ecosystem resilience in the Southern Ocean but persistent perturbations in the equatorial Pacific owing to regional iron retention. Balancing climate benefits and ecological risks yields three tiers: the Southern Ocean (higher efficiency/lower risk); the equatorial Pacific and global fertilization (higher efficiency/higher risk); and the subtropics (lower efficiency/moderate risk). Sixtyyears of fertilization yield net CDR of 1.15.3ppm,。
