项目摘要
During the ANDRILL-MIS project, for the first time, a 1000 m thick Plio-Pleistocene sediment sequence will be drilled from underneath the Ross McMurdo Ice Shelf (Antarctica). The variations of the ice shelf are controlled by the natural dynamic of the Antarctic ice sheets, by sea level fluctuations and by direct response of the ice shelf to climate changes. Geological evidence of ice shelf variations in the past is proposed being documented in different sediment facies in a 900 m deep moat basin under the ice. On the MIS core we propose high-resolution measurements of elemental concentrations and sediment physical properties using an XRF-core scanner and a multi-sensor core logger, respectively. In combination with geochemical and sediment-component investigations on discrete samples we will provide a calibrated high-resolution multivariable data-set for complex interpretations of paleoenvironmental changes from full glacial to open marine conditions during super-warm interglacials. Signals generated during sedimentation should be discriminated from provenance signals. Our major goal is a better understanding of the long-term evolution and stability of the Ross Ice Shelf as important part of the West Antarctic Ice Sheet for assessing future impacts of Antarctic ice masses on sea level and global oceanic circulation in times of rapid global climate change.
在ANDRILL-MIS项目中,将首次从罗斯麦克默多冰架(南极洲)下钻探1000米厚的上新世-更新世沉积物序列。冰架的变化受南极冰盖的自然动力、海平面波动和冰架对气候变化的直接反应的控制。在一个900米深的冰下护城河盆地中,不同的沉积相记录了过去冰架变化的地质证据。在MIS岩心上,我们建议分别使用xrf岩心扫描仪和多传感器岩心记录仪对元素浓度和沉积物物理性质进行高分辨率测量。结合对离散样品的地球化学和沉积物成分的调查,我们将提供一个校准的高分辨率多变量数据集,用于在超暖间冰期从完全冰川到开放海洋条件的古环境变化的复杂解释。沉积过程中产生的信号应与物源信号区分开来。我们的主要目标是更好地了解罗斯冰架作为南极西部冰盖的重要组成部分的长期演变和稳定性,以评估南极冰盖在全球气候快速变化时期对海平面和全球海洋环流的未来影响。
