The biological pump drives carbon storage in the deep ocean and is thought to function via gravitational settling of organic particles from surface waters. However, the settling flux alone is often insufficient to balance mesopelagic carbon budgets or to meet the demands of subsurface biota. Here we review additional biological and physical mechanisms that inject suspended and sinking particles to depth. We propose that these 'particle injection pumps' probably sequester as much carbon as the gravitational pump, helping to close the carbon budget and motivating further investigation into their environmental control. specialized 021 032 036 568 7752 327-335 2019 0028-0836 https://www.documentation.ird.fr/hor/fdi:010075629 10.1038/s41586-019-1098-2 0028-0836 [F B010075629] https://www.documentation.ird.fr/hor/fdi:010075629 https://www.documentation.ird.fr/intranet/publi/2019/05/010075629.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2019-06-04 2025-02-24 fdi:010075629 fre
