Rafael Marcé1*, Daniel Diaz-de-Quijano2,3†‡§, Sofía Rodríguez-Gómez4†, Enrique Moreno-Ostos4, Makhambet Mukhtar5, Björn Wissel6, Zoraida Quiñones-Rivera6, Carolina Olid7, Santiago Giralt8, Joan Pere Casas-Ruiz9, Georgiy Kirillin10, Daniel Mercado-Bettín1, Valentí Rodellas11, Jordi Ibáñez-Insá8, Núria Catalán1 lakes store large quantities of carbon in their sediments, contributing to climate regulation. yet the fate of this carbon after lake desiccation remains unclear. using a space-for-time substitution approach, combining sediment cores, carbon dioxide flux measurements, and remote sensing, we quantified organic carbon losses from the world’s largest desiccated lake, the Aral Sea. Since 1960, exposed lake bed sediments have released 204 ± 53 teragrams of carbon (Tg C), with vegetation growth offsetting less than 1%. …
