The IODP proposal ‘Cenozoic climate, productivity, and sediment transport at the NW African continental margin’ suggests investigating: i) NW African climate in a warmer world, and ii) High productivity ecosystem response to climates different from today. Sediment cores should be retrieved in six areas off NW-Africa. A central site is proposed on the Cape Verde Plateau close to ODP Site 659 but no modern high-resolution seismic data are available for this area. Such data will be collected during RV Meteor-Cruise M155 in the period May 26 to June 30, 2019. The main goal of this DFG proposal is the processing and interpretation of the new seismic data in order to develop a seismic stratigraphic framework for the Cape Verde Plateau. The work aims in identifying a site where the Plio-Pleistocene is thinner and the Miocene is thicker than at Site 659. This would allow to APC-XCB deeper into the Miocene, which is crucial for retrieving high-quality cores for paleoclimate investigations.

IODP提案“非洲西北部大陆边缘的新生代气候、生产力和沉积物运输”建议调查：i）更温暖世界中的非洲西北部气候，ii）高生产力生态系统对不同于今天的气候的反应。应在非洲西北部沿海的六个地区提取沉积物岩心。建议在佛得角高原靠近ODP 659号站点的地方建立一个中心站点，但该地区没有现代高分辨率地震数据。这些数据将在2019年5月26日至6月30日期间的RV Meteor-Cruise M155期间收集。该DFG提案的主要目标是处理和解释新的地震数据，以便为佛得角高原建立地震地层框架。这项工作的目的是确定一个地点，其中上新世-更新世较薄，中新世较厚，比659号地点。这将使APC-XCB更深入到中新世，这对于检索高质量的岩心进行古气候调查至关重要。
