长链烷基二醇及其指标在南海北部粤东沿海上升流地区的环境指示
|
摘要
本文以南海北部粤东沿海夏季上升流三个短柱状岩心为研究对象,通过二醇化合物分布分析测试和二醇环境参数的定量化重建,初步探讨了过去80年来海水表层温度(SST)、上升流活动和沉积环境演变过程及其交互关系。二醇温度指标(LDI)在粤东沿海地区较好地指示了年均SST,在三个岩心中均显示了整体增加的分布特征和相似的多年尺度变化趋势。此外,LDI-SST和二醇参数2具有非常好的线性关系(R~2=0.85,n=49),其整体分布、多年尺度变化均和ENSO旋回一致,并且大部分高/低值和ENSO暖/冷年、南海夏季风强/弱年具有很好的对应关系,表明了二醇参数2可以作为粤东上升流强度变化(多年/单年尺度)的替代性指标。而1,14-二醇含量和ENSO指标在多年尺度上显示了相似的波动特征,但大部分高/低值和南海夏季风指数、ENSO指标呈反相分布,说明了仅用1,14-二醇含量不可反演粤东上升流。据此,利用二醇参数2初步重建了过去80年来粤东上升流演变信息:上升流强度整体上显示加强的分布趋势,大体上呈约2~5年周期变化。此外,三个岩心中1,15-C_(30)(二醇/二醇+酮醇)比值和二醇参数2在整体上和多年尺度上均呈现相反的分布特征,可能与上升流活动导致的1,15-C_(30)二醇母源再悬浮再氧化有关,而普遍较高的1,15-C_(30)二醇比值(≥0.82)反映的强还原环境则和上升流地区水体中含氧量普遍偏低相关。
This study examined three short columnar sediment cores from the summer upwelling region along the east coast of Guangdong,in the northern South China Sea(SCS).Through analyses of diol distribution and quantitative reconstruction of diol environmental parameters,we conducted a preliminary exploration on the sea surface temperature(SST),upwelling activity and evolution of the sedimentary environment,and their mutual interactions,over the last 80 years.The results show that the long-chain diol index(LDI)was a good indicator of the annual average SST in the coastal area of eastern Guangdong,where the distribution characteristics from three sediment cores showed an overall SST increase and a similar multi-year timescale trend.In addition,LDI-SST and diol parameter 2 showed an excellent linear relationship(R~2=0.85,n=49),with consistent overall distribution,mean multi-year variations,and El Ni1 o-Southern Oscillation(ENSO)cycles.And the majority of high/low values correlated well with ENSO warm/cold cycles or strong/weak years of the SCS summer monsoon.These results indicate that diol parameter 2 can be regarded as a representative indicator of the upwelling strength in eastern Guangdong(multi-year/single-year timescale).1,14-diol content and ENSO index showed similar fluctuation characteristics on a multi-year time-scale,indicating 1,14-diol content alone can not reflect information on the multi-year variations of upwelling.Therefore,diol parameter 2 was used for the preliminary reconstruction of upwelling evolution over the last 80 years in eastern Guangdong.The upwelling strength showed an overall increasing distribution trend,with a～2 to 5-year variation cycle;the overall/multi-year distribution characteristics of the 1,15-C_(30)(diol/diol+acyloin)ratio,on the other hand,showed opposing trend with diol parameter 2,possibly a result of resuspension and reoxidation of 1,15-C_(30) diol source due to upwelling activities.Higher 1,15-C_(30) ratio(≥0.82)generally reflects a strong reducing environment,which has a poor correlation with oxygen content in thewater body of the upwelling region.
