项目摘要

- Created a compilation of proxies for past sea level during the last interglacial (approximately 120,000 years ago) for areas in North America and Europe covered by the penultimate glaciation. I will use these constraints to create paleotopography reconstructions during the last interglacial. My role in this study was to develop the compilation methodology and to enter the data in the World Atlas of Last Interglacial Shorelines (WALIS). Published in Dalton et al., 2022, Earth System Science Data, https://doi.org/10.5194/essd-14-1447-2022- Compiled sea level constraints during the Last Glacial Maximum (approximately 20,000 years ago), including in eastern Asia. These constraints allow us to assess how much of the East China Sea was exposed, and how narrow the Tsushima/Tsugaru Straits were, to set up our climate modelling experiments on the East Asian monsoon (Gowan et al., in review, Nature Communications).- Worked on four other papers that have been accepted for publication. These papers focus on topics related to past climate change, and the evolution of ice sheets. These studies have application to my planned work on paleotopography reconstructions. Gowan et al., accepted with minor revisions, Journal of Glaciology; Hinck et al., The Cryosphere, https://doi.org/10.5194/tc-16-941-2022; Dalton et al., Global Planetary Change, https://doi.org/10.1016/j.gloplacha.2022.103814; Yang et al., PLOS ONE, https://doi.org/10.1371/journal.pone.0259816. I also have worked on three other papers that have yet to be submitted.

- 为北美洲和欧洲倒数第二次冰期覆盖的地区创建了上一次间冰期（大约 12 万年前）过去海平面的代理汇编。我将利用这些约束来重建末次间冰期的古地形。我在这项研究中的作用是开发编译方法并将数据输入世界末次间冰期海岸线地图集 (WALIS)。发表于 Dalton 等人，2022 年，地球系统科学数据，https://doi.org/10.5194/essd-14-1447-2022 - 编译了末次盛冰期（约 20,000 年前）期间的海平面限制，包括东亚。这些限制使我们能够评估东海的暴露程度以及对马/津轻海峡的狭窄程度，以建立东亚季风的气候模拟实验（Gowan 等人，评论，《自然通讯》） .- 撰写的其他四篇论文已被接受发表。这些论文重点关注与过去气候变化和冰盖演化相关的主题。这些研究适用于我计划的古地形重建工作。 Gowan 等人，稍作修改后接受，《冰川学杂志》； Hinck 等人，《冰冻圈》，https://doi.org/10.5194/tc-16-941-2022； Dalton 等人，《全球行星变化》，https://doi.org/10.1016/j.gloplacha.2022.103814； Yang 等人，PLOS ONE，https://doi.org/10.1371/journal.pone.0259816。我还完成了另外三篇尚未提交的论文。
