项目摘要
As the overall aim, this project focuses on studying the last glacial-interglacial cycle of the Southern Hemispheric mid-latitudes (52°S). Drilling of the sediment record of Laguna Potrok Aike, a 770 ka old maar lake in the dry steppe of southern Patagonia (Argentina), provides a unique record of environmental and climate variations. Results will be compared with marine Southern Ocean and Antarctic ice core data as well as with modelling results and help to understand how climate interacts globally. Stable isotope investigations of sedimentary organic matter and lacustrine carbonates will focus on core catcher samples and the complete composite profile from the central basin. Organic carbon and nitrogen isotopes will give insights into lacustrine primary production and organic matter sources. Oxygen and carbon isotope composition of lacustrine carbonates, plant macroremains and sedimentary cellulose will allow evaluating changes in the hydrological cycle of southern Patagonia. In collaboration with national and international science teams these investigations will make available qualitative climate and environmental reconstructions at multi-millennial to multi-decadal resolution. The results will give insights into temporal changes of intensity and latitudinal position of the Southern Hemisphere Westerlies interacting with the Antarctic Circumpolar Current in the hemispheric and global distribution of moisture and energy. Altogether, these results provide information on lacustrine productivity, origin of organic matter, allochthonous sediment supply and hydrological variations that are directly and indirectly related to ecological processes and climatic forcing.
作为总体目标,该项目的重点是研究南半球中纬度地区(52°S)的末次冰期-间冰期循环。拉古纳波特罗克艾克(Laguna Potrok Aike)是阿根廷巴塔哥尼亚南部干草原上一个已有770 ka历史的玛阿尔湖,对该湖的沉积物记录进行钻探,提供了环境和气候变化的独特记录。研究结果将与南大洋和南极冰芯数据以及模拟结果进行比较,并有助于了解气候如何在全球范围内相互作用。对沉积有机质和湖相碳酸盐的稳定同位素调查将侧重于取心器样品和中央盆地的完整复合剖面。有机碳和氮同位素将有助于了解湖泊初级生产力和有机质来源。湖相碳酸盐、植物大残体和沉积纤维素的氧和碳同位素组成将允许评估巴塔哥尼亚南部水文循环的变化。在国家和国际科学小组的合作下,这些调查将提供千年到十年分辨率的定性气候和环境重建。研究结果将有助于了解南半球西风带与南极绕极流相互作用的强度和纬度位置的时间变化,以及半球和全球的水汽和能量分布。总之,这些结果提供了信息湖生产力,有机质的起源,外来沉积物供应和水文变化,直接和间接相关的生态过程和气候强迫。
