In contrast, anthropogenic aerosols provide nutrients and exert a fertilizing effect, but its contribution to evolution of oceanic productivity is unknown. We simulate the response of oceanic biogeochemistry to anthropogenic aerosols deposition under varying climate from 1850 to 2010. We find a positive response of observed chlorophyll to deposition of anthropogenic aerosols. Our results suggest that anthropogenic aerosols reduce the sensitivity of oceanic productivity to warming from -15.21.8 to -13.31.6PgCyr(-1)degrees C-1 in global stratified oceans during 1948-2007. The reducing percentage over the North Atlantic, North Pacific, and Indian Oceans reaches 40, 24, and 25%, respectively. We hypothesize that inevitable reduction of aerosol emissions in response to higher air quality standards in the future might accelerate the decline of oceanic productivity per unit warming. specialized ocean productivity anthropogenic aerosols nutrient limitation ocean biogeochemical model PACIFIQUE ATLANTIQUE OCEAN INDIEN 036 064 021 126 020 42 24 10745–10754 2015 0094-8276 https://www.documentation.ird.fr/hor/fdi:010066158 10.1002/2015gl066753 0094-8276 [F B010066158] https://www.documentation.ird.fr/hor/fdi:010066158 https://www.documentation.ird.fr/intranet/publi/2016/02/010066158.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2016-02-26 2017-08-23 fdi:010066158 fre
