海面下に着底した東南極氷床の安定性に関する研究

第一阶段：完成了东南极阿德利盆地高分辨率样品的制备，并完成了加速器质谱仪对铍同位素的分析。正在准备一份详细说明高分辨率数据集的手稿，准备提交给一份科学期刊。第二阶段：利用加速器质谱仪对来自东南极塞布里纳海岸地区的更多样本进行了铍同位素分析。与附近较浅深度的核心进行比较，揭示了数据中一些有趣的差异，尽管这些核心位置很接近。这些结果正在与合著者讨论，数据以海报的形式提交给日本地球科学联盟会议和美国地质学会会议。第三阶段：用加速器质谱仪分析了塔斯马尼亚西海岸塞利纳湖的样品，涵盖了过去的五个海洋同位素阶段(MIS1-5)。随着样本数量的增加，看到比预期更强的气候信号是很有趣的。这项分析的结果以口头报告的形式在美国地质学会会议上公布，手稿已经完成，正在与合著者讨论。它很快就会被提交给一份科学期刊。

Phase 1: Preparation of the high resolution Adelie Basin, East Antarctica samples has been completed, and analysis of beryllium isotopes by accelerator mass spectrometry is finished. A manuscript detailing the high resolution dataset is being prepared for submission to a scientific journal.Phase 2: Additional samples from the Sabrina Coast region of East Antarctica have been analyzed by accelerator mass spectrometer for beryllium isotopes. Comparison to a nearby core at a shallower depth reveal some interesting differences in the data, despite the proximity of the core sites. The results are under discussion with coauthors, and the data was presented at the Japan Geosciences Union meeting and the Geological Society of America meeting in poster form.Phase 3: Samples from Lake Selina in the West Coast Range of Tasmania have been analyzed by accelerator mass spectrometry, covering the past five marine isotope stages (MIS 1-5). With a greater sample number, it has been interesting to see a stronger climate signal than expected. The results from this analysis were presented at the Geological Society of America meeting as an oral presentation, and the manuscript is complete and under discussion with coauthors. It will shortly be submitted to a scientific journal.
