The remaining 11-28% supposedly comes mainly from glacially-derived sediments and airborne dust. Until recently, the contribution from rock coasts was estimated to represent 0.4 Gt/a, representing only 2-4% of the total flux. For the first time, and using the most complete global compilation of sea cliff recession rates in Europe, this study evaluates the rock coast contribution to sediment flux. We show that this sediment flux has been largely underestimated, and reveal that cliff derived sediment supply is only three times less than the solid discharge of rivers (111 & PLUSMN; 65 vs. 290 Mt/a) for Europe. This new estimate of the rock coast erosion should be included in future studies on the evolution of the surficial Earth system. specialized rock coast seacliff sediment budget erosion geochemical budget Quaternary EUROPE MEDITERRANEE ATLANTIQUE COTE DE LA MER NOIRE 064 062 032 579 117356 [9 ] 2022 0012-821X https://www.documentation.ird.fr/hor/fdi:010084661 10.1016/j.epsl.2021.117356 0012-821X [F B010084661] https://www.documentation.ird.fr/hor/fdi:010084661 https://www.documentation.ird.fr/intranet/publi/2022-06/010084661.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2022-06-03 2025-02-24 fdi:010084661 fre
