A record of Holocene East Asian Monsoon variability from Sunda Shelf, South China Sea sediments, UMT-ECU 2013

UMT ECU 2013

The South China Sea has been the focus of many paleoclimatological studies due to its central location to the EAM system. However, most studies have been conducted in the northern SCS because of the high sedimentation rates there.  The southern SCS, specifically the Sunda Shelf, has yet to yield a monsoon record due to its very thin sedimentary cover. However, flooded fluvial channels from the Last Glacial Maximum may contain a longer sedimentary record.

The purpose of  this study is to determine whether fluvial paleochannels on the Sunda Shelf provide a lengthy and continuous sedimentary record that might be useful for paleoclimate studies. Geochemical proxies such as Mg/Ca paleothermometry and stable isotopic analysis will be applied to sediment cores from these paleochannels. If climate signals are recognizable, data from these cores will be compared with deep marine, lake, speleothem, and loess-paleosol records from the region.
