First long-term detection of paleo-oceanic signature of dust aerosol at the southern marginal area of the Taklimakan Desert

Abstract We firstly conducted a long-term in-situ field measurement at a marginal area (Hotan) of the southern Taklimakan Desert covering all four seasons. Detailed chemical characterization of dust aerosol over Hotan showed several unconventional features, including (1) ubiquity of high Na+ and Cl−...
