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

基金将支持一个国际研讨会，该研讨会致力于组织一项国际计划(ALBICORE)，以调查全球气候-海洋对白垩纪中期温室(约1亿年前)轨道强迫的响应模式。我们在意大利阿尔比亚的工作揭示了沉积和古生物的振荡，其周期与轨道变化的周期相对应。这种不同类型的响应在其他中生代地层层序中也有记录，但仍然是孤立的案例。温室气候对轨道强迫做出了反应，但要更好地了解气候和地球年代学，就需要制定一幅给定时间的全球响应图景。ALBICORE的目的是推动在这样一个时间片上的国际工作--早发性微囊线虫的阿尔比亚区。讲习班力求(1)通过展示已经取得的成就和扩大这种工作的前景来引起人们的兴趣；(2)展示我们开发和发现的有用的多学科技术(沉积学、古生物学、地球化学和地球物理学)，并讨论替代方法和改进；以及(3)制定一项总体程序计划，其中包括：(A)一系列战术行动小组，负责钻探岩芯及其分析工作；(B)咨询委员会，负责就技术提供咨询意见，并有助于寻找实验室设施；(C)指导委员会，负责协调全球努力。

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.
