Precipitation variation in the northern South China Sea of the last 700 years reconstructed by lagoon sediments
Precipitation changes in the East Asia are closely linked to the monsoonal climate in this region and the hydrothermal processes in the western tropical Pacific. However, trends of reconstructed precipitation records for the past millennium are inconsistent and the influencing factors are in dispute. Here we reconstruct a 700-year precipitation record for the northern South China Sea (SCS) using grain size of lagoon sediments. Our data revealed that precipitation increased in the early to middle Little Ice Age, possibly modulated by tropical cyclones and the Walker Circulation. The East Asian Summer Monsoon and Pacific Decadal Oscillation had the major influence on the precipitation changes in the northern SCS. This study provides new insight into the processes and the underlying mechanisms of climate changes in the SCS.
期刊介绍:
Marine Geology is the premier international journal on marine geological processes in the broadest sense. We seek papers that are comprehensive, interdisciplinary and synthetic that will be lasting contributions to the field. Although most papers are based on regional studies, they must demonstrate new findings of international significance. We accept papers on subjects as diverse as seafloor hydrothermal systems, beach dynamics, early diagenesis, microbiological studies in sediments, palaeoclimate studies and geophysical studies of the seabed. We encourage papers that address emerging new fields, for example the influence of anthropogenic processes on coastal/marine geology and coastal/marine geoarchaeology. We insist that the papers are concerned with the marine realm and that they deal with geology: with rocks, sediments, and physical and chemical processes affecting them. Papers should address scientific hypotheses: highly descriptive data compilations or papers that deal only with marine management and risk assessment should be submitted to other journals. Papers on laboratory or modelling studies must demonstrate direct relevance to marine processes or deposits. The primary criteria for acceptance of papers is that the science is of high quality, novel, significant, and of broad international interest.
