Early to mid-Holocene sedimentary evolution on the southeastern coast of Hangzhou Bay, East China, in response to sea-level change

We examined the lithology, sedimentary structure, marine microfossils, and chronology in two sediment cores collected from the southeast coastal plain of Hangzhou Bay, aiming at the infilling history of the palaeo-Ningbo Bay during the early to mid-Holocene transgression. We share the original data of grain size and marine microfossils in one sediment core CC here. Other data are included in the manuscript.
