Collaborative Research: Southern Hemisphere Mid-Depth Water Masses and the Instability of the Ocean's Conveyor Circulation--The Marine Sediment Record from Southwest Africa

为从西南非洲边缘收集一套岩心提供了资金，以构建几个详细的深度样带，以监测中深水团的完整动态范围和地层几何形状。巡航后提出的研究计划将建立南半球海洋环流对更新世和全新世期间主要不稳定因素的敏感性，通过绘制底栖有孔虫中放射性碳分布在特定突发事件中的变化，推断中深水的通气历史，并帮助描绘南北来源。

Funds are provided for a cruise to collect a suite of cores from the Southwest African margin to construct several detailed depth transects to monitor the full dynamic range and stratal geometry of the mid depth water masses. The post-cruise proposed research program will establish the sensitivity of Southern Hemisphere ocean circulation to major instability during the Pleistocene and Holocene by mapping changes in the distribution of radiocarbon in benthic foraminifera over specific abrupt events to deduce the ventilation history of mid-depth water and help delineate northern vs. southern sources.
