9713344 Austin Joint US-German MCS and wide-angle seismic experiment to study the Galicia Interior Basin/Galicia Bank rifted continental margin and transform boundary with Iberia Abyssal Plain margin segment to the south. S-reflector under the Galicia outer Bank will be the focus. A dense instrumented MCS/OBS wide angle seismic profile (56 OBS deployments) and 12 deep-penetrating MCS profiles are planned. The sediment-starved Galicia Margin is well constrained and has no post-rift volcanic or slat tectonics associated with it which makes is a good place to study rifted margins. Existing ODP data will provide ground truth.

9713344 奥斯汀 美国-德国联合MCS和广角地震实验，研究加利西亚内盆地/加利西亚浅滩裂谷大陆边缘以及与伊比利亚深渊平原边缘段南部的边界转换。加利西亚外岸下方的 S 型反射器将成为焦点。 计划建立密集的仪器化 MCS/OBS 广角地震剖面（56 个 OBS 部署）和 12 个深穿透 MCS 剖面。缺乏沉积物的加利西亚边缘受到良好的约束，并且没有与之相关的裂谷后火山或板条构造，这使得它成为研究裂谷边缘的好地方。现有的 ODP 数据将提供基本事实。
