| 1 | Biomarker evidence for changes in terrestrial organic matter input into the Yellow Sea mud area during the Holocene显示文摘We present lipid biomarker records of two cores(ZY1 and ZY3) from the central South Yellow Sea mud area to investigate the changes in sources and transport processes of the sedimentary organic matter(OM) throughout the Holocene. Based on the analysis of marine biomarker content(SPB(Phytoplankton Biomarker, total content of brassicasterol, dinosterol and C_(37)-alkenones) and crenarchaeol), and terrestrial biomarkers(Sn-alkanols and br GDGTs) as well as TMBR′ and BIT index values, the marine organic matter(MOM) and terrestrial organic matter(TOM) deposition history was reconstructed. Changes in TOM and MOM were related to variations in land vegetation density and marine productivity, as well as transport processes dominated by the oceanic circulation system. The marine biomarker contents from the South Yellow Sea have generally increased throughout the Holocene, indicating that the increased MOM contents were mainly controlled by the strengthening of the circulation system. The terrestrial biomarkers, on the other hand, were more variable, indicating more complex influence of TOM burial in the Yellow Sea. During the Early Holocene(7200–6000 cal yr BP), the moderate TOM input revealed by the terrestrial proxy records may result from abundant land source supply by strong river transport despite the lack of transport via circulation system. The Mid-Holocene(6000–3000 cal yr BP) was characterized by decreased terrestrial biomarker contents. The balance between the decrease in land source supply and increase of transportation by the current system of the TOM resulted in the lower but stable contents of TOM. During the Late Holocene(3000 cal yr BP to present), the TOM deposition in the South Yellow Sea increased as the current system was further enhanced and thus transported more TOM to the central South Yellow Sea, although the land supply of TOM was further reduced. | WU Peng XIAO XiaoTong TAO ShuQin YANG ZuoSheng ZHANG HaiLong LI Li ZHAO MeiXuna | 2016 | Science China Earth Sciences2016，59，6： | 6 |
| 2 | 中全新世以来南黄海岩心记录的沉积环境演变对东亚季风的响应显示文摘对南黄海中部泥质沉积区中心位置的Z1钻孔进行了AMSMC年龄、粒度和TOC/TN分析,综合指标结果揭示了中晚全新世以来南黄海区域的沉积环境演化。自6094aBP以来,沉积速率、平均粒径和TOC/TN整体趋势的减少指示,研究区陆源物质输入的减少与东亚冬/夏季风的减弱有关。根据粒度参数和TOC/TN变化将研究区沉积环境演化分成3个阶段:①6.1~5.4kaBP时沉积物粒度最粗,TOC/TN值较高,这与该阶段东亚冬季风的强盛且稳定和黄海暖流的形成初期较弱有关;②5.4~3.9kaBP时沉积物粒度减小但波动幅度较大,TOC/TN值呈减小趋势,此阶段东亚冬季风减弱但波动剧烈;③3.9~0kaBP时沉积物粒度较细且相对稳定,TOC/TN增加直至趋于稳定,该阶段冬季风减至最弱且趋于稳定。另外岩心记录的6.0、5.3、4.6、4.0和3.4kaBP沉积物粒度明显较粗、TOC/TN值较大与东亚冬季风增强、海区温度较低有关;6.1~5.7kaBP的高速沉积与冬季风强盛有关;2.8~1.9kaBP的高速沉积则与黄海沿岸流和黄海暖流共同作用形成的南黄海中部气旋式冷涡的加强稳固有关。 | 皮仲 李铁刚 南青云 | 2016 | 海洋地质前沿2016，32，7： | 6 |
| 3 | Reconstruction of phytoplankton productivity and community structure in the South Yellow Sea显示文摘The sedimentary environment and ecological system in the South Yellow Sea (SYS) changed dramatically due to sea level change caused by glacial-interglacial cycles. The authors report the use of marine biomarkers (brassicasterol, dinosterol and C37 alkenones) and terrigenous biomarkers (C28+C30+C32 nalkanols) in core DLC70-3 from the SYS to reconstruct the variation in the phytoplankton productivity and community structure and possible mechanisms during the middle Pleistocene. The results show that the primary productivity and that of single algae presented a consistent trend for the whole core during the middle Pleistocene, which was high during interglacial periods and low during glacial periods, with the highest being in marine isotope stage (MIS) 5–9 and MIS 19–21. The main reason is that the Yellow Sea Warm Current (YSWC) carried much of high temperature, high salinity water into the SYS, causing upwelling and vertical mixing and stirring, which increased the nutrient supply in the photosynthetic layer. The phytoplankton community structure mainly showed an increase in the relative content of haptophytes in MIS 5–9 and MIS 19–21, while the relative content of diatoms and dinoflagellates decreased;there was no evidence for a haptophyte content in other stages. The results reveal a shift from a coccolitho-phoriddominated community during MIS 5 –9 and MIS 19 –21 to a diatom-dominated community during the other stages, mainly as a result of surface salinity variation, attributed to the invasion of the YSWC during high sea level periods. | Xi Mei Ri-hui Li Xun-hua Zhang Zhong-bo Wang Yong Zhang | 2019 | China Geology2019，2，3： | 5 |
| 4 | 生物标志物重建全新世以来黄海浮游植物群落结构时空变化显示文摘现有研究对全新世以来浮游植物群落结构在黄海的时空变化还缺乏深入认识,针对这一问题,本研究分析了C02和N05岩心中的生物标志物,并结合已发表岩心生物标志物数据,重建黄海全新世以来浮游植物群落结构的时空变化。在早全新世,长链烯酮相对比例(A/∑PB)和菜子甾醇相对比例(B/∑PB)低,甲藻甾醇相对比例(D/∑PB)高。较高的陆源有机质指标(TMBR′)值说明黄海浮游植物群落结构主要受陆源营养盐输入控制。在中全新世,A/∑PB升高,B/∑PB和D/∑PB减小,是由于高温高盐的黄海暖流入侵有利于颗石藻生长。在空间分布上,以ZY3、ZY2、ZY1和YE-2 4个站位组成的35.5°N断面区域烯酮相对比例大幅升高,西部站位C02与东部N05烯酮比例小幅上升,这是由于黄海暖流主轴流经35.5°N断面,该区域主要受黄海暖流控制,而其他区域仍受陆源营养盐输入控制。从早全新世到中全新世,B/∑PB(D/∑PB)高值相继出现在N05(C02)和C02(N05)区域,这是由于2个站位的控制因素不同,可能与黄海暖流主轴摆动和陆源物质的搬运有关。在晚全新世,A/∑PB继续升高,B/∑PB和D/∑PB减小。晚全新世东亚冬季季风增强使黄海环流体系加强,黄海暖流对颗石藻的影响进一步扩大。甲藻甾醇与菜子甾醇的相对比例(D/B)升高,可能是由于东亚冬季季风增强,使含有更多氮元素的大气物质沉降到黄海,有利于甲藻对硅藻的竞争。 | 吴珺洁 袁子能 向荣 张海龙 肖晓彤 赵美训 | 2017 | 海洋学报2017，39，10： | 1 |
| 5 | 中全新世以来南黄海中部沉积过程——基于岩心粒度和有机质指标显示文摘海陆交互作用下的南黄海沉积环境复杂,其沉积机制一直是古海洋研究的重点和难点。本文以取自南黄海中部泥质区的Z1岩心为载体,对196个样品的粒度和整体有机质指标(TOC、TN、TOC/TN和δ13Corg)进行了详细分析,并对5个层位进行AMS14C年龄测定,分辨率高达11 a/cm。研究结果显示,6.1 ka BP以来南黄海中部沉积过程可分为3个阶段:(1)6.1~5.2 ka BP,沉积物粒度较粗,以残留砂和陆源粗粒物质为主,有机质含量较低且主要为陆源输入,本阶段多受东亚季风强盛的影响,动荡海洋环境下有机质保存效率低,大量陆源输入冲淡作用显著;(2)5.2~3.9 ka BP,沉积物粒度变细且波动较大,有机质呈增加趋势且以海源为主,主要受东亚冬季风减弱的影响,海源有机质含量增加,与黄海暖流影响增强有关;(3)3.9~0 ka BP,沉积物粒度最细且相对稳定,有机质含量继续增加,直至1.9 ka BP趋于稳定,主要受现代环流系统和东亚冬季风影响。结果表明,南黄海粒度和整体有机质指标变化过程复杂,显示中全新世以来南黄海中部泥质区沉积环境演化的复杂性。本研究获得了南黄海高分辨率的沉积环境演化记录,不仅为沉积机制研究提供更多数据支撑,还可为区域古气候和古海洋演化提供关键的指示证据。 | 皮仲 李铁刚 类彦立 | 2019 | 海洋学报2019，41，11： | 1 |
| 6 | 南黄海北部晚更新世以来浮游植物生产力和群落结构变化的生物标志物记录显示文摘冰期—间冰期引起的海平面变化会导致黄海的沉积环境和生态系统发生巨大变化。通过多参数生物标志物法对取自南黄海北部71.2m长的DLC70-3岩心进行研究,获得晚更新世以来的浮游植物生产力和种群结构变化信息,并探讨影响其变化的可能因素。结果表明,晚更新世以来,DLC70-3岩心的浮游植物初级生产力和单一藻类生产力总体上呈现一致的变化趋势,在MIS 5e和MIS 3c时期最高,而在其他层位较低。浮游植物种群结构的变化主要表现为颗石藻在MIS 5e和MIS 3c相对含量增加,硅藻和甲藻相对含量下降,而颗石藻在其他层位含量为0。这都归因于高海平面时黄海暖流的入侵导致黄海盐度发生了较大的变化。 | 梅西 李日辉 张训华 | 2015 | 矿物岩石地球化学通报2015，34，5： | 1 |
| 7 | Sea surface temperature evolution in the Yellow Sea Warm Current pathway and its teleconnection with high and low latitude forcing during the mid-late Holocene显示文摘Sea surface temperature(SST)in the Yellow Sea Warm Current(YSWC)pathway is sensitive to the East Asian Winter Monsoon(EAWM)and YSWC.However,the role of the YSWC in the evolution of regional SST remains unclear.Here,we present new U 37 k′based SST and grain size sequences spanning the last 6092 years in the sediment core Z1,which was retrieved from the central Yellow Sea muddy area.Overall,U 37 k′-SST gradually increased since 6.1 ka BP,with a series of centennial-scale fl uctuations.Its variation was mainly caused by EAWM when YSWC was weak between 6.1 and~3.9 ka BP,as shown by the end-member content of grain size.However,after YSWC was fully developed,i.e.,since~3.9 ka BP,it exerted critical eff ects on SST evolution in its pathway.The 1010-and 538-year cycles of the SST sequence indicated a basic control of solar activity on the oceanic conditions in the Yellow Sea.It is suggested that the variation of total solar irradiance was amplifi ed by thermohaline circulation and then transmitted to the Yellow Sea through the EAWM.Meanwhile,the tropical Pacifi c signal of El Niño was transmitted to the YSWC through the Kuroshio Current.The dual properties of warm water transported by YSWC to compensate the EAWM and driving by Kuroshio Current closely linked the variation of SST in the YSWC pathway to the Northern Hemisphere high latitude climate and the tropical Pacifi c.These fi ndings highlight the signifi cance of YSWC on regional SST evolution and its teleconnection to high and low latitude forcing,which grains a better understanding of the long-term evolution of SST in the middle latitude Yellow Sea. | Zhong PI Fengming CHANG Tiegang LI Yikun CUI | 2022 | Journal of Oceanology and Limnology2022，40，1： | 1 |
| 8 | 山东半岛北岸跨锋面物质输运对辽东半岛东岸沉积有机质含量及来源的影响显示文摘深入理解气候变化影响下海洋动力过程变化及其多重环境效应,是了解海岸海洋系统未来演化趋势的重要途径。因此,本文在辽东半岛东岸泥质区取柱状样一根,通过沉积物粒度、TOC/TN含量、δ13C以及δ15N等指标,分析气候变化下山东半岛北岸跨锋面物质输运强度变化,及其对辽东半岛东岸泥质区沉积有机质含量和来源的影响。结果表明,高海面时期以来,山东半岛北岸跨锋面物质输运可分为两个变化阶段:6.5~2.9 cal ka BP,其强度随冬季风和黄海暖流的不断减弱而减弱;2.9 cal ka BP至今,由于冬季风较弱而黄海暖流总体强盛,其强度随黄海暖流的波动而呈现4段式的复杂变化。此外,辽东半岛东岸泥质区陆源和海源有机质含量与其强度呈正相关,相应于跨锋面物质输运强度的变化,6.5~2.9 cal ka BP期间,陆源和海源有机质含量持续减少,而2.9 cal ka BP至今则呈现复杂的4段式变化。总体上看,自6.5 cal ka BP以来,陆源有机质贡献率不断下降而海源有机质贡献率逐渐上升。 | 舒卓 高建华 石勇 徐笑梅 | 2022 | 海洋通报2022，41，1： | 1 |
| 9 | Middle Holocene Organic Carbon and Biomarker Records from the South Yellow Sea: Relationship to the East Asian Monsoon显示文摘The East Asian monsoon system influences the sedimentation and transport of organic matter in East Asian marginal seas that is derived from both terrestrial and marine sources. In this study, we determined organic carbon(OC) isotope values, concentrations of marine biomarkers, and levels of OC and total nitrogen(TN) in core YSC-1 from the central South Yellow Sea(SYS). Our objectives were to trace the sources of OC and variations in palaeoproductivity since the middle Holocene, and their relationships with the East Asian monsoon system. The relative contributions of terrestrial versus marine organic matter in core sediments were estimated using a two-end-member mixing model of OC isotopes. Results show that marine organic matter has been the main sediment constituent since the middle Holocene. The variation of terrestrial organic carbon concentration(OCter) is similar to the EASM history. However, the variation of marine organic carbon concentration(OCmar) is opposite to that of the EASM curve, suggesting OCmar is distinctly influenced by terrestrial material input. Inputs of terrestrial nutrients into the SYS occur in the form of fluvial and aeolian dust, while concentrations of nutrients in surface water are derived mainly from bottom water via the Yellow Sea circulation system, which is controlled by the East Asian winter monsoon(EAWM). Variations in palaeoproductivity represented by marine organic matter and biomarker records are, in general, consistent with the recent EAWM intensity studies, thus, compared with EASM, EAWM may play the main role to control the marine productivity variations in the SYS. | ZOU Liang HU Bangqi LI Jun DOU Yanguang XIE Luhua DONG Liang | 2018 | Journal of Ocean University of China2018，17，4： | 1 |
| 10 | 运用生物标志物研究全新世南黄海泥质区陆源有机质输入的变化显示文摘分析南黄海中部泥质区柱状样ZY1和ZY3中的生物标志物,来研究全新世沉积有机质的来源和运输过程的变化.根据海源生物标志物(菜子甾醇、甲藻甾醇和长链烯酮含量的总和(?PB,Phytoplankton Biomarker)和泉古醇(crenarchaeol))、陆源生物标志物(烷醇(?n-alkanols)和土壤厌氧细菌生物标志物(br GDGTs))以及TMBR′和BIT指标,重建了全新世黄海海源有机质(marine organic matter,MOM)和陆源有机质(terrestrial organic matter,TOM)的沉积历史.结果表明海源有机质和陆源有机质的变化与陆地植被丰度、海洋浮游植物生产力和海洋环流系统的输运过程有关.受海洋环流系统不断增强的影响,全新世南黄海海源生物标志物含量呈增加趋势,指示了海源有机质输入的增多.陆源生物标志物含量变化波动较大,揭示了影响黄海陆源有机质埋藏的因素可能更复杂:早全新世(7200~6000cal a BP)陆源有机质输入量适中,由于环流系统还未形成,输运黄海陆源有机质有限,但仍存在河流输运的陆源有机质.中全新世(6000~3000cal a BP)陆源有机质含量较低,陆源有机质供应的减少和环流系统输运的增强共同导致陆源生物标志物含量减少,但是变化趋势比较稳定.晚全新世(3000cal a BP至今)南黄海陆源有机质增加,原因是尽管陆地有机质的供应减少,但由于环流系统增强,输运较多陆源有机质至南黄海中部. | 吴鹏 肖晓彤 陶舒琴 杨作升 张海龙 李莉 赵美训 | 2016 | 中国科学:地球科学2016，46，6： | 1 |
| 11 | Foraminiferal Changes and Response to the Channel Diversion and Discharge Fluctuation of the Yellow River in the North Yellow Sea During the Past Century显示文摘Diversion of the Yellow River is a unique geological event in offshore China,causing changes of the sedimentary environment in eastern China Seas.The last diversion took place in AD 1855,with the estuary diverted from the Yellow Sea into the Bohai Sea.The identification of the river diversion events in the shelf sediments would not only provide the definite ages for the sediments,but also give a clue for better understanding of the sedimentation in that area.In this study,210 Pb,grain size,geochemical element,and foraminiferal data in core H205 from the north Yellow Sea were systematically investigated.A high-resolution sedimentary record was established,which was coupled with the Yellow River diversion and runoff changes.The results show that the foraminiferal composition and foraminiferal abundance of the sediments from the north Yellow Sea had good response to the Yellow River diversion in 1855.Before the change,shallow water assemblages dominated the foraminifera,and the abundance of each foraminiferal species was very low.After the diversion event,the abundance of most foraminifera increased sharply,with a maximum increase of 16 times,and the assemblage was still dominated by shallow water species.Furthermore,the changes in foraminiferal abundance in the core sediments corresponded well with the discharge fluctuation of the Yellow River since 1855.When the Yellow River began entering the Bohai Sea,the Yellow River water,which is rich in nutrients,along with the coastal currents affected the north Yellow Sea,increased the primary productivity in the north Yellow Sea,which is the main reason for the abrupt increase and fluctuation of foraminiferal abundance in this area.At the meantime,the East Asian winter monsoon could also promote the development of nearshore foraminiferal species by enhancing the coastal currents. | ZHENG Shiwen FAN Dejiang TIAN Yuan XU Jingping | 2019 | Journal of Ocean University of China2019，18，6： | 0 |
