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.

- 在上一次冰河中（大约120，000年前）在北美和欧洲被倒数第二个冰川覆盖的地区创建了过去海平面的代理。我将使用这些约束来在上一次冰川间期间创建古分形重建。我在这项研究中的作用是开发汇编方法，并输入最后一次冰间海岸线（Walis）世界地图集。 Earth System Science数据发表在Dalton等，2022年，https：//doi.org/10.5194/essd-14-1447-1447-2022-在最后一次冰川最大值（大约20，000年前）中汇总了海平面约束，包括东亚。这些限制使我们能够评估东方海的暴露程度，以及Tsushima/tsugaru海峡的狭窄程度，在东亚季风中建立了我们的气候建模实验（Gowan等人（Gowan等人），在审查，自然通讯中）。这些论文重点介绍了与过去的气候变化有关的主题以及冰盖的演变。这些研究适用于我计划的古代形态重建工作。 Gowan等人接受了少量修订，冰川学杂志； Hinck等人，Cryosphere，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。我还研究了尚未提交的其他三篇论文。
