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，我们预计将在北大大西洋东北部的ODP站点1049测试Erbacher等人（2001）提出的“超级推进阶段”，并进一步阐述Herrle（2002）和Herrle等人（2003a+b）提出的下Albian海洋缺氧事件1b的“超级季风假说”。我们建议研究该模型对马扎甘高原（MP）和沃肯盆地（VB）两个热带和亚热带气候带的气候相关预测，即上升流条件、风力、大陆径流、有机质生产力和水柱氧合。我们打算生成具有高时间分辨率的大陆和海洋代理记录。这两个部分将通过全球d13ccar地层联系起来。这个时间框架将允许追踪单个进动周期的分辨率过程，并可用于调查(i)在每个地点的生产力和/或水柱缺氧/缺氧变化的时间、原因和影响，最重要的是，（ii）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的碳埋藏阶段。该项目的结果不仅可以评估超级季风假说的基本原理，而且还可以提高我们对下阿尔bian期间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.
