In this paper,the palynological analysis of two marine core,MD06-3075 (06.4762°N,125.8322°E;1 878 m water depth,30.76 m in length) in the southern Philippines and MD98-2178 (03.6200°N,118.7000°E;1 984 m water depth,35.6 m in length) in the north East Borneo,the detailed oxygen isotope records,and other marine pollen records in the West Pacific,provide the regional vegetation and climate history since the Last Glacial.Based on AMS14C dating and plankton foraminifera oxygen isotope record,the core MD06-3075 covers last 52 ka,and the core MD98-2178 covers last 92 ka (pollen analysis includes records of the last 77 ka).The palynological record shows low representation of mangrove pollen and fern spore during the glacial period,indicating lower sea level and drier climate condition during the glacial period than the deglacial period,especially the last glacial maximum.However,through the comparison of marine pollen records in the West Pacific area,there are some different pollen records in the southern South China Sea.It shows significantly high value of mangrove pollen from a marine core in the slope area and fern spore from marine core in the Sunda Shelf.These differences may be caused by the drop of sea level change,which lead to the explosion of the Sunda Shelf and the changes of vegetation distribution and distance between vegetation source and deposition point.Therefore,the interpretation of marine pollen data should be combing with the multiple sedimentary index and the geophysical survey record,which would raise the recognition of the influence of sea level change and the corresponding sedimentary environment evolution on marine pollen transportation and deposition,enhancing the extraction of the paleoclimate and paleoenviroment information from the marine palynology.
