Sedimentation processes on Walvis Ridge - correlation of high resolution seismic records with ODP Leg 208 physical properties data

ODP提案559-Full，“早期新生代极端气候：沃尔维斯岭样带”（Zachos等人）。将在即将到来的ODP第208条（08.03）中实现。- 09.05.03)。ODP第208条的主要目标是古近系的极端气候条件，利用天文周期定年，重建古海洋学的发展。主要研究对象为古新世—始新世热极值（55.5 Ma）、早期生态新世气候极值（52 ~ 50 Ma）和早渐新世冰川极值（33.4 Ma）。2001年初的流星巡航M49/1是ODP Leg 208的主要地震现场前调查。地震数据结合旧的DSDP数据是为即将到来的ODP Leg 208选择新位置的基础。在这一建议的框架内，我们计划通过计算合成地震图，将地震数据与新的钻井结果结合起来。这些数据将用于分析目标反射体的地震特征并绘制其空间分布图。我们还想研究在新钻探地点发现的其他特征，如洋流对沉积的影响，以及沉积速率和断裂的空间分布，这将导致沃尔维斯岭沉积过程的表征。

The ODP proposal 559-Full, "Early Cenozoic Extreme Climates: The Walvis Ridge Transect" (Zachos et al). will be realized during the upcoming ODP Leg 208 (08.03. - 09.05.03). The main objectives of ODP Leg 208 are extreme climatic conditions in the Paleogene, dating utilizing astronomical cycles, and the reconstruction of the paleoceanographic development. Primary targets are the Paleocene-Eocene Thermal Maximum (55,5 Ma), the Early Ecocene Climatic Optimum (52-50 Ma), and the Early Oligocene Glacial Maximum (33.4 Ma). Meteor Cruise M49/1 in early 2001 was the main seismic pre-site survey for ODP Leg 208. The seismic data in combination with old DSDP data were the basis for selecting new locations for the upcoming ODP Leg 208. In the framework of this proposal we plan to combine the seismic data with the new drilling results through calculation of synthetic seismograms. These data will be used to analyze the seismic signatures of the target reflectors and to map their spatial distribution. We also want to investigate other features identified in the new drill sites, such as the influence of currents on the sedimentation as well as the spatial distribution of sedimentation rates and hiatuses, which shall lead to a characterization of depositional processes on Walvis Ridge.
