This project aims to evaluate the viability of engineering the ocean to remove carbon dioxide from the atmosphere by simulating a suite of climate intervention and baseline scenarios. To better predict changes in marine carbon cycling, I will first make novel observations of zooplankton grazing dynamics, then use them to improve, validate and constrain a new marine biogeochemical model. Using this model, coupled to an ocean, atmosphere and fisheries model, I will quantify the long-term efficiency with which marine carbon dioxide removal strategies sequester carbon along with their impact on fisheries catch. These projections will help scientists, policy-makers, and industry leaders decide if, when, and how we should geoengineer the ocean.

该项目旨在通过模拟一系列气候干预和基线情景，评估海洋工程从大气中去除二氧化碳的可行性。为了更好地预测海洋碳循环的变化，我将首先对浮游动物的放牧动态进行新的观察，然后利用它们来改进、验证和约束一个新的海洋生物地球化学模型。利用这个模型，结合海洋、大气和渔业模型，我将量化海洋二氧化碳去除策略封存碳的长期效率以及它们对渔业捕捞的影响。这些预测将帮助科学家、政策制定者和行业领袖决定我们是否、何时以及如何对海洋进行地球工程。
