Due to the short nature of the instrumental record of sea-level change, development of proxies for sea-level change prior to the advent of instrumental records is essential to reconstruct long-term background sea-level changes on local, regional and global scales. Here, we employ numerical methods to partition sediment grain size using a combined database of marine surface and core samples, and to quantitatively reconstruct sea-level variation since the late Pleistocene in the south Bohai Sea, China. Our sea-level reconstruction indicates that relative sea-level changes in the southern Bohai Sea track global sea-level variation for the duration of the record. The results also indicate substantial regression from 70 to 30 cal kyr BP, and potentially subarial exposure from 38 to 20 cal kyr BP. Our results document the feasibility of reconstructing relative sea-level change by numerical partitioning of sediment grain size data, demonstrating the potential for future applications. STUDY NOTES: Sediment grain size data, foraminifera abundance, and reconstructed Bohai Sea relative water level from coastal sediment core LZ908, covering the past 1.327 million years. This data set is an extension of the Yi et al. 2012 data set, (http://www.ncdc.noaa.gov/paleo/study/13286) which is reconstructed Bohai Sea relative water level for 135KYrs.
