Utilizing the geological record to constrain the response of marine ecosystems and global carbon cycling to warming and de-oxygenation

地球历史被气候、生物地球化学循环和生态系统中各种各样的转变和扰动所打断，其中一些可能包含直接与未来相关的信息。在海洋中，它们在一个复杂的反馈网络中密切相关，还与海洋的氧合作用和过量碳释放到大气中的最终地质命运--将碳埋藏在沉积物中--密切相关。该项目将开发一个表示这种碳-气候-生命耦合系统的计算机模型，并根据地质记录对其进行测试，探索碳释放事件和物种灭绝的原因和后果，以及海底输送和保存有机碳的反应。

Earth history is punctuated by a huge variety of transitions and perturbations in climate, biogeochemical cycling, and ecosystems, some of which may hold direct future-relevant information. In the oceans, these are closely linked in a complex web of feedbacks, as well as to the oxygenation of the ocean and the ultimate geological fate of excessive carbon released into the atmosphere – burial of carbon in sediments. This project will develop a computer model representation of this coupled carbon-climate-life system and test this against the geological record, explore the causes and consequences of carbon release events and extinctions as well as how the ocean floor delivery and preservation of organic carbon responds.
