Controls of carbon burial during the Lower Albian OAE 1b in the western Atlantic/western Tethys on Milankovitch time scales: Testing the climatic connection of tropical and subtropical areas as suggested by Mega-Monsoon-Hypothesis

在这个项目中，我们预计将测试Erbacher等人提出的“超级腐泥阶段”。(2001)在北大西洋东北部的ODP1049站，并进一步阐述了Herrle(2002)和Herrle等人提出的“大季风假说”。(2003a+b)下阿尔卑斯大洋缺氧事件1b。我们建议对热带和亚热带气候带--马扎干高原(MP)和沃康盆地(VB)--的上升流条件、风力强度、大陆径流、有机质生产力和水柱氧合作用进行气候相关预测。我们打算生成具有高时间分辨率的大陆和海洋代理记录...这两个区段将通过全球d13Ccar地层学联系在一起。这一时间框架将能够追踪单个岁差周期的解析过程，并可用于调查(1)生产力和(或)水柱缺氧/真氧变化对每个地点的大规模有机碳埋藏的时间、原因和影响，最重要的是，(2)在一个共同的时间尺度上展示东大西洋和西特提斯热带和亚热带气候带碳埋藏的阶段性。这个项目的结果不仅可以评估大季风假说的基本原理，而且还可以改善我们对下阿尔卑斯时期全球气候行为的理解。

In this project we anticipate to test the proposed "super-sapropel stage" by Erbacher et al. (2001) at ODP Site 1049 in the north-eastern North Atlantic and further elaborated to the "Mega-Monsoon-Hypothesis" by Herrle (2002) and Herrle et al. (2003a+b) for the Lower Albian Oceanic Anoxic Event 1b. We propose to investigate climate related predictions of this model for two lacations from the tropical and subtropical climate zones - the Mazagan Plateau (MP) and the Vocontian Basin (VB) - i.e., upwelling conditions, wind strength, continental runoff, organic matter productivity and water column oxygenation. We intent to generate continental and marine proxy records with a high time resolution... for both sections which will be linked via the global d13Ccar-stratigraphy. This time framework will allow to trace processes on the resolution of an individual precession cycle and can be utilized to investigate (i) the timing, causes and effects of changes in productivity and/or water-column anoxia/euxinia on massive organic carbon burial at each location, and, most important, to (ii) demonstrate the phasing of carbon burial in the tropical and sub-tropical climate belts of the eastern Atlantic and Western Tethys on one common time scale. The results of this project will not only allow to evaluate fundamentals of the Mega-Monsoon-Hypothesis, but also improve our understanding of the global climate behaviour during the Lower Albian.
