Abstract

As a result of an analysis of published works, a database on paleotemperatures in the Arctic and Subarctic regions based on marine invertebrate skeletons, marine palynomorphs, dinosaur teeth, analysis of the ability of reptiles to lay eggs at low temperatures, terrestrial floral assemblages (CLAMP-analysis), the presence of coal interbeds in continental deposits within the Arctic region, and on membrane lipids of glycerol and dialkylglycerol tetraether in marine sediments and glendonite was assembled. Based on the obtained data, a paleotemperature curve for the Cretaceous–Cenozoic stage of geological history of the Arctic region was constructed. The general trends of this curve are in consistent with the global paleotemperature curve (Scotese, 2015) (with the exception of the cooling period in the Tortonian due to local factors). In total, 16 climatic cycles in the climatic history of the Arctic, including 16 climatic minima (including the glaciation in the Northern Hemisphere) and 15 climatic maxima have been established.

白垩纪和新生代北极地区的气候变化

摘要

对已发表著作进行分析的结果是，建立了基于海洋无脊椎动物骨骼，海洋拟变形虫，恐龙牙齿的北极和亚北极地区古温度数据库，分析了爬行动物在低温下产卵的能力，陆地花卉组合（CLAMP） -分析），组装了在北极地区的大陆沉积物中以及在海洋沉积物和皂石中甘油和二烷基甘油四醚的膜脂上存在煤夹层的存在。根据获得的数据，绘制了北极地区白垩纪至新生代地质历史阶段的古温度曲线。该曲线的总体趋势与全球古温度曲线一致（Scotese，2015年）（由于局部因素，Tortonian的冷却期除外）。总共，
