Holocene Dune Mobility and Forcing Mechanisms at the Northern Margin of the East Asian Monsoon
Abstract: Dune fields at the northern margin of the East Asian monsoon (EAM), are mosaics of mobile and vegetation‐stabilized aeolian dunes. These sand dunes are highly sensitive to environmental change, thus the distribution and the timing of their development may provide important clues to past en...
