Organizing ALBICORE Workshop: Milankovitch Forcing of Climate and Oceans in the Greenhouse State (100 MA BP)

资金将支持一个国际研讨会，专门组织一个国际项目（ALBICORE），研究中白垩纪温室（大约距今1亿年）气候-海洋对轨道强迫的全球响应模式。我们在意大利阿尔比安的工作揭示了沉积和古生物学振荡的周期与轨道变化的周期相对应。在其他中生代地层层序中也有不同类型的反应，但仍是个别情况。温室气候对轨道强迫作出了反应，但为了更好地理解气候和地质年代学，需要对给定时间的反应形成一幅全球图景。ALBICORE旨在促进这样一个时间片的国际工作- Ticinella praticinensis的Albian分区。讲习班寻求(1)通过展示已完成的工作和扩大此类工作的承诺来产生兴趣；(2)展示我们已经开发并发现有用的多学科技术（沉积学、古生物学、地球化学和地球物理），并讨论替代方法和改进方法；(3)制定总体程序计划，包括(a)一套负责岩心钻探和分析的战术行动小组，(b)提供技术咨询并有助于寻找实验室设施的咨询委员会，以及(c)协调全球工作的指导委员会。

Funds will support an international workshop devoted to the organization of an international program (ALBICORE) to investigate global patterns of climatic-oceanic response to orbital forcing in the Mid-Cretaceous greenhouse (ca. 100 million years BP). Our work in the Italian Albian has revealed sedimentary and paleontological oscillations with periods corresponding to those of the orbital variations. Such responses of different sorts have been recorded in other Mesozoic stratigraphic sequences, but remain isolated cases. Greenhouse climates responded to orbital forcing, but application to a better understanding of Climates and Geochronology calls for developing a global picture of the responses for a given time. ALBICORE is designed to foment international work on such a time-slice - the Albian sub-zone of Ticinella praeticinensis. The workshop seeks (1) to generate interest by showing what has been accomplished, and the promise of extending such work; (2) to demonstrate the multidisciplinary techniques (sedimentological, paleontological, geochemical and geophysical) that we have developed and found useful, and to discuss alternatives and improvements; and (3) to develop an overall plan of procedure, including (a) a set of tactical ACTION GROUPS that would undertake the drilling of cores and their analysis, (b) ADVISORY COMMITTEES that would serve to advise on techniques and would be helpful in finding laboratory facilities, and (c) a STEERING COMMITTEE that would coordinate the global effort.
