Holbrook 9401374 Upcoming Delaware multichannel seismic experiment across the Aleutian Arc will collect high quality vertical incidence seismic refraction data across and active continental and island arc system. The PI's will piggyback on this cruise to record sound energy generated by airguns at the ocean bottom. This will provide deep velocity structure data of both continental and oceanic arcs as well as direct imaging of wide-angle reflectivity from the system boundaries. The data will help reconcile conflicting hypothesis of deep structure and composition of the arc systems.

霍尔布鲁克9401374即将进行的跨阿留申弧地的特拉华州多道地震实验将收集跨活动大陆和岛弧系统的高质量垂直入射地震折射数据。PI将搭乘这次巡航记录海底气枪产生的声能。这将提供大陆弧和海洋弧的深层速度结构数据，以及从系统边界直接成像广角反射率。这些数据将有助于调和关于弧系深层结构和组成的相互矛盾的假设。
