The aim of this interdisciplinary research project is an enhanced understanding of the driving factors of Holocene climate variability along the East Antarctic coast, a key question in the face of future Antarctic climate change. By combining two innovative approaches, the proposed study will clearly go beyond previous research work. Firstly, the project focuses on a renewed compilation of existing paleoclimate reconstructions from East Antarctica with improved chronologies of sedimentary records by new compound-specific radiocarbon studies. Secondly, high-resolution climate simulations and paleoenvironmental reconstructions from the wider Prydz Bay region will be tightly coupled to distinguish between local, regional and large-scale climate patterns. In-Depth evaluation of available data sets and numerical simulation results will lead to a rigorous test and further improvement of the models and proxies used for paleoenvironmental reconstructions. This interdisciplinary project will thereby deliver new, important insights to the present stage of the East Antarctic late Quaternary environmental history. It will substantially contribute to an enhanced understanding of the interactions between historical variability in climate and paleoenvironmental reconstructions along the East Antarctic coast.

该跨学科研究项目的目的是对全新世沿海沿海地区全新世气候变化的驱动因素的驱动因素的增强，这是面对未来南极气候变化的关键问题。通过结合两种创新方法，拟议的研究显然将超越以前的研究工作。首先，该项目着重于对东南极洲东部现有的古气候重建的重新汇编，并通过新的化合物特异性放射性碳研究改进了沉积记录的时间顺序。其次，高分辨率的气候模拟和更广泛的Prydz湾地区的古环境重建将紧密耦合，以区分局部，区域和大规模的气候模式。对可用数据集的深入评估和数值模拟结果将导致严格的测试，并进一步改善用于古环境重建的模型和代理。该跨学科项目将在南极晚期环境历史的当前阶段提供新的，重要的见解。它将大大有助于增强对南极沿海气候和古环境重建的历史变异性之间的相互作用。
