1爪哇海末次冰盛期以来的季风与穿越流活动记录显示文摘文章通过SHl9034岩芯氧同位素曲线、AMS ^14C测年、浮游有孔虫组合及其所反映的温盐变化特点,并与爪哇海北部的SHl9006岩芯对比研究,获得如下认识:末次冰期2l~15kaB.P.阶段,爪哇海区东南季风强而西北季风微弱,气候冷干,混合层薄,生物生产力高;15~10kaB.P.和10~7kaB.P.阶段由于海平面迅速上升,望加锡海峡和龙目海峡通道变宽,出现较强的表层穿越流活动;早全新世东南与西北季风都有增强,说明当时研究区气候有着更强的季节性;7~3kaB.P.阶段,爪哇海北部的穿越流主要在温跃层水中传输,到达爪哇上升流区时,上升至表层,使得混合层增厚,同时也抑制了上升流活动;约3kaB.P.以来,研究区穿越流活动表现与现代相近的性质,主要在温跃层水中传输。丁旋 方念乔 F.

2印度尼西亚弗洛勒斯海LGM以来的古海洋学记录显示文摘弗洛勒斯海位于印度尼西亚穿越流通道上,它的古海洋学特征对于理解LGM以来穿越流活动历史,及其与全球气候变化的关系具有重要意义.通过对弗洛勒斯海SHI9011岩心δ18O、δ13C、浮游有孔虫组合及碳酸盐含量等古海洋学记录的研究,认为研究区沉积速率不高,生物生产力却并不低于高沉积速率的近陆地区.冰期时海平面下降,陆源物质输入量增加,使得古生产力上升.冰消期终止期IA海平面快速上升,陆源营养物质供应减少,同时穿越流活动增强,抑制了下部水体向上运动,古生产力开始下降.8~6 ka前后,强烈的东南季风使得研究区上升流活动增强.丁旋 Guichard F.

3The B/Ca and Cd/Ca of a subsurface-dwelling foraminifera Pulleniatina obliquiloculata in the tropical Indo-Pacific Ocean: implications for the subsurface carbonate chemistry estimation显示文摘Pulleniatina obliquiloculata shells from 16 core-top samples from the tropical Indo-Pacific Oceans are analyzed for the ratios of boron and cadmium to calcium(B/Ca and Cd/Ca). The B/Ca ratios show a very weak positive relationship with [B(OH)_4^-] and the dissolved carbonate species at the apparent calcification depth of P.obliquiloculata. The boron partition coefficients(K_D) between P. obliquiloculata B/Ca and seawater[B(OH)_4^-]/[HCO_3^-] distribute around 1.1×10^(-3)-1.3×10^(-3) with a mean value of(1.19±0.12)×10^(-3),and are significantly related to the nutrient concentration, especially phosphate. The lack of any clear correlation between the P. obliquiloculata B/Ca and seawater carbonate chemical parameters suggests that the physiochemical controls on boron incorporation are masked by the complexity of natural seawater condition. But the significant dependence of Ku on nutrient may likely be explained by a nutrient related growth-rate effect. Cd/Ca of P.obliquiloculata shows significant correlation with seawater phosphate concentration, and its partition coefficients(D_(cd)) are significantly related to temperature. A first-principle methodology of P. obliquiloculata B/Ca is applied;with the aid of Cd/Ca as a phosphate proxy and a constraint on K_D, to estimating sea water carbonate chemistry(e.g., pH). The results are fairly promising and allow us to propose the possibility to apply the combination of B/Ca and Cd/Ca proxies(and also Mg/Ca and δ^(18)O for estimating temperature and salinity) for the paleoreconstruction of seawater carbonate chemistry.Haowen Dang Tingting Wang Peijun Qiao Franck Bassinot Zhimin Jian 2019Acta Oceanologica Sinica2019,38,3:2

15Mg/Ca Variation in Planktonic Foraminiferal Tests:Assessing Influence of Salinity and Diagenetic Carbonate Dissolution for Reconstruction of Palaeo-seawater Temperature显示文摘Over the past decade,the Mg/Ca ratio in foraminiferal tests has emerged as a valuable paleotemperature proxy.In this study we describe the application of the Mg/Ca paleothermometer with the aim of illustrate its use in the Mediterranean Basin.We value the influence of the salinity and diagenetic carbonate processes besides temperature as an important environmental factor controlling the foraminiferal Mg/Ca.For this purpose 3 species ofAnna Sabbatini Frank Bassinot Alessandra Negri 2009地学前缘2009,16,S1:0
