Holocene Environment of far-east Siberia

堪察加半岛和千岛群岛位于气候敏感的理想环境中。气候波动是由复杂的因素驱动的，如全球大气环流、洋流和构造活动。在湖泊沉积记录的多代理研究基础上，提出了全新世西伯利亚远东地区气候环境变化的定量重建。重点是新开发的区域chironomid为基础的T七月和大陆性推理模型（传递函数）的应用，通过合并现代东北西伯利亚和西西伯利亚训练数据集，早期由第一个申请人开发。为了进行重建，我们建议研究堪察加半岛中部和南部的三个湖泊的沉积物岩心以及千岛群岛中部和南部的四个沉积物岩心。所有的场地都沿着南北向的样带，沿着千岛-堪察加弧线。chironomid的分析结果将与生物标志物、硅藻、花粉和麻药的分析结果进行比较。部分出版的记录是可用的。该项目的成果提供了全新世环境变化的详细概述，以及不同生态因素在该地区复杂气候历史中的重要性。此外，该项目将带来独特的分类和生物地理信息。它将继续我们之前在该地区的工作，将提供对全球气候驱动因素和北大西洋与北太平洋地区之间遥相关的见解，并在欧亚大陆研究最少的地区之一的全球自然过程背景下，更好地理解区域因素（主要包括暖流和冷洋流的迁移和灾难性事件）相互作用的环境意义。

The Kamchatka Peninsula and Kurile Islands are ideally situated in a very climate-sensitive setting. Climate fluctuations are driven by complex factors, such as global atmospheric circulation, ocean currents, and tectonic activities. The focus of the proposed project will be put forward on the quantitative reconstruction of climate and environmental changes in far-East Siberia during the Holocene, following a multi-proxy study of lacustrine sediment records. The focus is the application of newly developed regional chironomid-based T July and Continentality inference models (transfer functions), by merging modern North-East Siberian and West-Siberian trainings data sets, earlier developed by the first applicant. To perform the reconstructions, we propose to investigate sediment cores from three lakes in central and southern Kamchatka and four sediment cores from the central and southern Kuriles. All sites are situated along a north-south transect that follows the Kuril-Kamchatka Arc. Results of chironomid analysis will be compared with those derived from biomarkers, diatoms, pollen, and tephra analysis, performed by collaborators. Partly published records are available. The outcome of the project provides a detailed overview of Holocene environmental changes and the importance of the different ecological factors in the complex climate history of the region. In addition, the project will bring unique taxonomical and biogeographical information. It continues our previous work in the region, will provide insights into global climate drivers and teleconnections between the North Atlantic and North Pacific regions and leads to better understanding of the environmental significance of interactions of regional factors (including primarily migration of warm and cold ocean currents and catastrophic events) against the background of global natural processes in this one of the least studied region of Eurasia.
