该讲习班汇集了来自各个领域的专家，以制定一项钻探建议，填补我们对地球系统功能的理解中存在的“渐新世-中新世空白”。我们建议通过新的国际海洋发现计划（IODP）在北大西洋钻探，建立第一个连续的高沉积记录的渐新世-中新世，允许一个连续的新近纪旋回地层学的发展，并提高我们的知识的渐新世-中新世海洋冰气候动力学。研讨会于2014年9月15日至17日在海德堡举行，由ESF（EARTHTIME EU），NSF和ECORD MagellanPlus研讨会系列计划资助。来自六个不同国家（澳大利亚、法国、德国、荷兰、联合王国和美国）的24名与会者参加了研讨会，其中包括几名早期职业阶段的研究人员。我们讨论了新生代古海洋学和古气候的某些方面，以及如何利用科学钻探填补渐新世-中新世的空白。研讨会的最终目标（向IODP提交预提案）已经实现（IODP提案874-pre已于2014年10月1日提交）。我们的研讨会包括概况介绍，然后是自我选择的分组讨论，讨论不同的主题，并为提案提供文本和图表。在此，我们简要概述了研讨会期间讨论的主要议题以及由此产生的IODP预提案中提出的科学目标。
This workshop brought together specialists from various fields to develop a drilling proposal to fill the "Oligo-Miocene Gap" that exists in our understanding of the functions of Earth's systems. We propose to establish the first continuous high-deposition record of the Oligo-Miocene through new International Ocean Discovery Program (IODP) drilling in the North Atlantic to allow the development of a continuous Neogene cyclostratigraphy and to enhance our knowledge of Oligo-Miocene ocean–ice–climate dynamics. The workshop was held in Heidelberg from 15 to 17 September 2014 funded by ESF (EARTHTIME EU), NSF, and the ECORD MagellanPlus Workshop Series Program. A total of 24 participants from six different countries (Australia, France, Germany, the Netherlands, United Kingdom, and United States) attended the workshop, including several early career stage researchers. We discussed certain aspects of Cenozoic paleoceanography and paleoclimate and how the gaps in the Oligo-Miocene could be filled using scientific drilling. The ultimate goal of the workshop (to submit a pre-proposal to IODP) was achieved (IODP Proposal 874-pre was submitted 1 October 2014). Our workshop consisted of overview presentations followed by self-selected breakout groups that discussed different topics and produced text and figures for the proposal. Here, we give a short overview of the major topics discussed during the workshop and the scientific goals presented in the resulting IODP pre-proposal.
