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、地球化学循环和生态系统中的各种各样的转变和扰动所打断，其中一些可能包含与未来直接相关的信息。在海洋中，这些因素在一个复杂的反馈网络中密切相关，并与海洋的氧化作用以及释放到大气中的过量碳的最终地质命运-沉积物中碳的埋藏-密切相关。该项目将开发一个碳-气候-生命耦合系统的计算机模型，并对照地质记录进行测试，探索碳释放事件和排放的原因和后果，以及洋底有机碳的输送和保存如何应对。

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.
