英文摘要: Rapidly deposited and geochemically distinct volcanic ash (tephra) markers represent a powerful chronological tool that enables precise dating and correlation of geological archives. Recent analytical advances now allow fingerprinting of non-visible ash (cryptotephra) over thousands of kilometers. This has opened up tantalizing possibilities for the intercontinental synchronization of records. We present geochemical evidence to demonstrate that ash from a Svalbard lake sediment core correlates to the Kamchatkan KS2 eruption. By expanding the known dispersal range of cryptotephra by thousands of kilometers and linking the Pacific and Atlantic Arctic, this study raises cryptotephra analysis to a new level. Also, the presented findings mark a step towards a hemispheric tephrochronological framework. Finally, this study highlights the importance of looking beyond proximal volcanic sources to find a correlation. © 2017 Elsevier Ltd
资助项目: This study has received funding from the Norwegian Research Council through the project «Shifting Climate States of the Polar Regions» (210004) as well as the «INTIMATE» COST action (ES0907) and the alminnelige naturvitenskapelige Research Fund of the University of Bergen. We thank Rob D'Anjou, Bjørn Kvisvik and Torgeir Røthe for helping to retrieve the studied sediment cores. Finally, we like to express our gratitude to Victoria Cullen and Victoria Smith at RLAHA, University of Oxford, as well as Chris Hayward at the University of Edinburgh for their help with the geochemical analyses. Finally, we would like to express our gratitude to Vera Ponomareva and one anonymous reviewer for improving this manuscript with their comments.
