The ocean profoundly affects Earths climate by storing carbon dioxide in its deep waters away from the atmosphere. Dr. Hammes research seeks to quantify the processes that control this storage. Dr. Hamme will deploy novel robotic profiling floats in the North Pacific that measure oxygen, acidity, and nutrient levels throughout much of the ocean water column on several year missions. Using this data, her group will quantify the rate of marine biological productivity, especially the fraction that sinks into the deep ocean, and will explore the impact of unusual climatic events on ocean cycles.

海洋通过将二氧化碳储存在远离大气层的深水中，深刻地影响着地球的气候。哈姆斯博士的研究试图量化控制这种存储的过程。哈姆博士将在北太平洋部署新的机器人剖面浮标，在几年的任务中测量大部分海洋水柱的氧气、酸度和营养水平。利用这些数据，她的团队将量化海洋生物生产力的速度，特别是沉入深海的部分，并将探索异常气候事件对海洋循环的影响。
