Documenting climate-triggered changes in erosion patternsStreams are one of the most efficient sediment conveyors on Earth and as such, they play a key role in the erosion cycle (Aksoy and Kavvas, 2005). Reconstructing changes in river-borne sediment flux and origin from lake sediment might hence reflect the history of the in-land hydrology (Arnaud et al., 2012(Arnaud et al., , 2016. Dust mobilization and emission by wind into the atmosphere may also be important erosive mechanisms (Shao et al., 2011). Since the dust flux can contribute > 10% of the global river sediment flux, dust deposition from the atmosphere plays an important role in the biogeochemistry of the ECZ (Derry and Chadwick, 2007) and can be imprinted within lake sediment (Sabatier et al., 2020).
