南极布兰斯菲尔德海峡晚第四纪有孔虫埋藏群特征及其环境初探

分析了采自南极布兰斯菲尔德海峡海槽中ＰＣ１０孔（７５３ｃｍ长）的３９个样品，共鉴定有孔虫１４属２１种。有孔虫埋藏可分为硅质壳、钙质壳和混合壳组合。硅质壳组合代表正常的深海沉积环境，反映了相对弱的海底水动力条件；钙质壳组合是浊流沉积的产物，反映了很强的海底水动力条件；混合壳组合则代表趋于正常的深海沉积环境，反映了由强渐弱的海底水动力条件。晚第四纪以来，本区经历了暖－冷－暖的气候变化过程。     

A preliminary investigation of siliceous microfossil succession in late Quaternary sediments from Lake Baikal, Siberia

Siliceous microfossil assemblage succession was analyzed in a 100 m sediment core from Lake Baikal, Siberia. The core was recovered from the lake's central basin at a water depth of 365 m. Microfossil abundance varied greatly within the intervals sampled, ranging from samples devoid of siliceous microfossils to samples with up to 3.49 × 10¹¹ microfossils g^-1 sediment. Fluctuations in abundance appear to reflect trends in the marine ¹⁸O record, with peak microfossil levels generally representing climate optima. Microfossil taxa present in sampled intervals changed considerably with core depth. Within each sample a small number of endemic diatom species dominated the assemblage. Changes in dominant endemic taxa between sampled intervals ranged from extirpation of some taxa, to shifts in quantitative abundance. Differences in microfossil composition and the association of variations in abundance with climate fluctuations suggest rapid speciation in response to major climatic excursions.     

Climate-mediated changes in small lakes inferred from midge assemblages: the influence of thermal regime and lake depth

Subfossil midge (Chironomidae and Chaoboridae) assemblages were examined in the surficial sediments (0?C1?cm) from small inland lakes in the Experimental Lakes Area (ELA) of northwestern Ontario, Canada. In these boreal lakes, maximum depth (Z_max), alkalinity, Secchi depth and chlorophyll-a concentrations explained significant amounts of variation in the subfossil assemblages. Constrained ordinations (redundancy analysis) indicated that the relationship between Z_max (as sqrt Z_max) and assemblage composition was strong enough to develop a paleolimnological inference model. Model statistics suggested that a robust model was generated (r ²?=?0.78, RMSEP?=?0.533, max bias?=?0.674); however, when the model was applied to a subfossil stratigraphy from an ELA lake sediment core, results suggested that the inference model had produced an unrealistically shallow Z_max inference. Further analyses indicated that thermal regime had a strong influence on assemblage composition; when the influence of thermal regime was partialled out, there was a much weaker relationship between Z_max and assemblage composition, particularly for stratified lakes. A thermal regime inference model was subsequently developed, which, when applied to the lake sediment core stratigraphy, indicated that the shallow Z_max inference may have been the result of a period of increased mixing or polymixis in this stratified lake. Water column mixing may increase due to hypolimnetic warming and increased water clarity resulting from declines in dissolved organic carbon. In a training set where there are strong correlations between lake depth and assemblage composition, this relationship is not necessarily a strict function of lake depth, but of some other highly correlated variable, likely thermal conditions.     

南极布兰斯菲尔德海峡的硅质沉积物特征

根据粒度、微体生物组合、矿物组分和微量元素丰度,探讨了南极布兰斯菲尔德海峡中央海槽和南部下陆坡区冰－海沉积环境形成的硅质沉积物特征。硅质沉积物主要为硅藻软泥或粉砂质硅藻软泥,由微体生物遗体、粘土矿物、火山物质和陆源碎屑矿物所组成。硅质生物壳体主要为硅藻,含量＞３０％,含少量放射虫和硅质壳有孔虫。粘土矿物中蒙脱石的含量高达５２．５％,其次为陆源伊利石,高岭石和绿泥石含量相对较低。碎屑重矿物以橄榄石、辉石、角闪石等非稳定组合为特征,轻矿物主要包括石英、长石和火山玻璃。微量元素丰度特征与大洋现代表层沉积物有所区别。研究区硅质沉积作用具有多种物源、生物沉积作用居重要地位、陆源（包括火山）物质以粉砂和粘土级细质点为主、相对较高的沉积速率和受地质构造背景影响等特征。

150年来青藏高原南红山湖的介形类与环境变化

青藏高原西北部南红山湖2孔湖芯沉积物中的介形类动物群计有4属4种,据其分布特征划分出5个组合,各组合间的差异表现在介形类动物群丰度和每个种的丰度变化以及特征种的出现。通过分析介形类属种生态特征和组合变化对150年来的南红山湖环境变化进行了探讨。分析结果表明:1884年前为有缓慢水流注入的滨岸浅水期;1885～1970年间为湖水相对温暖期,在这期间湖泊环境仍有次一级的变化,其中,1885～1905年湖面迅速抬升,水深增大,水温也较高,1923～1944年为湖水温度另一个稍高期,1961～1969年湖面再次出现明显上升;1970年以来湖泊退缩、咸化。     

21世纪以来内蒙古沙尘暴特征及成因

利用2001—2015年气象资料,对21世纪以来内蒙古沙尘暴的时空分布特征、系统分型和动力成因进行了分析。结果表明：内蒙古沙尘暴主要发生在春季（以4月为最甚）,绝大部分区域性沙尘暴出现在冬半年;进入21世纪以来,沙尘暴呈波动减少趋势。内蒙古沙尘暴高发区沿着北部国境线呈西南—东北方向带状分布,有两个沙尘暴频发中心,分别位于巴丹吉林沙漠和浑善达克沙地。根据沙尘暴的发生区域与地面天气系统之间的动态位置关系,内蒙古沙尘暴可分为冷锋型、蒙古气旋型和其他型等3种类型,其中以冷锋型最为常见。在沙尘暴过程中,发生在深厚混合层中的干对流是起沙扬沙的主要因素,大风是形成大范围区域性沙尘暴的动力条件,高空急流的动量下传是形成大风的重要因素。

Temporal variations in the abundance and sinking flux of diatoms under fast ice in summer near Syowa Station, East Antarctica

To investigate the fate of ice algae released from sea ice, we investigated the abundance, species composition, and sinking flux of diatoms in the water column under fast ice near Syowa Station, Antarctica during the summer of 2005/2006. The diatom assemblage in the water column consisted of chain-forming planktonic species, in contrast to the under-ice assemblage dominated by pennate species reported from this site in the past; this dissimilarity suggests the presence of an unconsolidated platelet ice layer under the congelation ice, within which planktonic species can bloom. Among the dominant diatoms, Porosira pseudodenticulata and Pseudo-nitzschia cf. turgiduloides were dominant in the water column, and their water column stocks were higher than their mass sedimentation. These species apparently maintain their populations in the surface layer, as their production remains in the water column. In contrast, Fragilariopsis kerguelensis and Thalassiosira australis were scarce in the water column but rich in the flux, indicating active sinking and export of their production to the benthic ecosystem. This distinction in buoyancy control and sinking characteristics of the dominant diatoms on release from the fast ice influences the diatom species composition and carbon flow under the ice.
