SGER: Seismic Profiling of Rapidly Subsiding Reefs on Sabine Bank, Vanuatu: Preparing for a Future Opp'ty to Drill Ancient Reefs Representing Off-Peak and Lowstand Sea Levels ...

Sabine Bank是位于太平洋国家瓦努阿图的一个浅滩，被认为是一个珊瑚礁，它保存了海洋同位素阶段2到5期间海平面下降的罕见记录。该项目将利用机遇船获取Sabine Bank上间隔约0.1 km的线上的高分辨率婴儿潮图像和深拖曳啁啾图像。这些数据将用于识别和绘制该特征上的珊瑚礁聚集，作为在IODP项目主持下可能最终钻探这种相对罕见的化石珊瑚礁系统的现场调查任务。这项研究的更广泛影响包括提供全球气候变化的非古海洋学指标，并加强与一个法国研究小组的合作。

Sabine Bank, a shoal located in the Pacific nation of Vanuatu, is postulated to be a coral reef that preserves a rare record of sea level fall during marine isotopic stages 2 through 5. This project will take advantage of a ship of opportunity to acquire high-resolution boomer images and deep-towed Chirp images on lines spaced at ~0.1 km on the Sabine Bank. The data will be used to identify and map reef accumulations on the feature as a site survey task for possible eventual drilling of this relatively rare fossil reef system under the auspices of an IODP project. Broader impacts of the research include providing a non-paleoceanographic indicator of global climate change and strengthening collaboration with a French research team.
