Abstract

Abstract

Based on the sediment dating, we studied the historical changes of biogenic elements, carbon, nitrogen and phosphorus, in the sediment of Kuroshio mainstream, east of Taiwan, and investigated the sedimentary record of climatic and environmental changes for nearly one thousand years. The results show that the sedimentation rate of Kuroshio mainstream, east of Taiwan and south slope of Ryukyu Arc, is up to 34.2 cm/ka. Three stages could be roughly divided according to the sedimentation rates, which are basically the same with the division of Medieval Warm Period (MWP), Little Ice Age (LIA) and Current Warm Period (CWP). The carbon in the sediment is mainly inorganic, and the total inorganic carbon (TIC) gradually increases with great variation from 1850 AD, which exactly corresponds to the rapid rise of atmospheric CO₂. The variation of total organic carbon (TOC), however, is closely related to the change of East Asian Summer Monsoon (EASM) intensity. The EASM was weaker in LIA than in MWP and CWP, meanwhile the TOC content of the sediment in LIA is higher. That is because weaker EASM is conducive to the generation and transportation of wind dust from the Asian continent, which could supply nutrients and promote the primary productivity of relevant seas. From 1850 AD, the C:N:P ratios in the sediment gradually increases to higher than the Redfield ratio, which means the nutrient structure changed from N-depleted to N-abundant. This change is closely related to the rapid increase of nitrogen emissions in modern times. Overall, the biogenic indexes in the Kuroshio mainstream sediment clearly record and well respond to the climatic and environmental changes over the past millennium, especially the drastic environmental change caused by intensive human activities over the past 150 a.
