Environmentally sensitive grain-size component (ESGSC) extracted from grain-size data of a
sediment core B2, which were retrieved from mud area southwest off Cheju Island (MACI),
East China Sea (ECS), can be used to indicate the variations of East Asia Winter Monsoon
(EAWM), with high (low) content/mean-size of ESGCS denote to strong (weak) EAWM.
Combined with AMS 14 C datings core B2 provides a continuous high-resolution record of
EAWM changes over the past 2300 years, with an average resolution of 13 years. The …
