Testing the Shelf-Nutrient Hypothesis by Examining the Oceanic Phosphorus Cycle on Glacial Timescales

该项目的总体目标是利用ODP岩芯和冰川-间冰期（G-I）时间尺度来评估一系列地点的磷积累率。这些磷积累率（PAR），然后将被用来构建随时间变化的质量平衡的海洋，以评估这是如何变化的G-I时间尺度。辅助目标是将PAR与其他生物活性元素的替代物进行对比。了解P收支如何随时间演变，对于深入了解海洋-大气耦合系统是如何变化的非常重要。

FilippelliAbtsractThe overall goal of the project is to evaluate Phosphorus accumulation rates at an array of sites using ODP cores and targeting glacial-interglacial (G-I) time scales. These P accumulation rates (PAR) will then be used to construct time-dependent mass balance for the oceans, to evaluate how this has changed on G-I time scales. Subsidiary goals are to contrast PAR to other proxies for bioactive elements. The understanding how the P budget evolves through time is important for insights into how the coupled ocean-atmosphere system.
