Collaborative Research: P2C2--Sea-level Variability over the Past 200,000 years Precisely Reconstructed from Carbonate Deposits in Mallorcan Caves

研究人员的目标是构建西地中海盆地的高分辨率海平面曲线，作为更好地了解全球海平面变化的努力的一部分。马略卡岛包含沿海洞穴，通过沉积独特的碳酸盐结壳捕捉现在和过去的海平面，这些碳酸盐结壳恰好形成于海平面位置。马略卡岛沿海洞穴之所以被选为这项研究的原因，是因为它们证明了获得高分辨率海平面历史的能力，以及由于其独特的构造和均衡环境，该地区对于解决海平面变化问题的重要性。这项研究的结果将引起对海平面变化和冰盖在一系列边界条件下的脆弱性感兴趣的广泛科学家的广泛兴趣。该项目还将促进美国和西班牙科学家之间的密切合作，并将支持研究生和本科生。

The researchers aim to construct a high resolution sea level curve for the western Mediterranean Basin as part of an effort to better understand global sea level variations. The island of Mallorca contains coastal caves that capture present and past sea level through the deposition of unique carbonate encrustations that form precisely at the sea level position.The coastal caves of Mallorca were chosen for this study because of their demonstrated ability to obtain a high resolution sea-level history and the importance of the locality for addressing the issue of eustatic sea level change due to its unique tectonic and isostatic setting.The results of the study will be of broad interest to a wide range of scientists interested in sea level variability and the vulnerability of ice sheets under a range of boundary conditions. The project will also foster strong collaborations among American and Spanish scientists and will support graduate and undergraduate students.
