Processed multichannel seismic data along the southern Alaskan margin, acquired during the R/V Maurice Ewing survey EW0408 (2004)

As part of a site survey for a proposed IODP program to drill marine sediments associated with late Cenozoic climate change and tectonic activity along the southern Alaskan margin, the researchers combined efforts with an already funded piston coring and shallow imaging cruise. The purpose was to acquire additional piston cores and high-resolution seismic images at proposed Gulf of Alaska drill sites. The marine seismic data is to be used in sequence stratigraphic correlations and baseline characterization of the proposed IODP drill sites.

为配合一项拟实施的国际大洋发现计划（International Ocean Discovery Program, IODP）科考项目的现场调查——该项目旨在钻探阿拉斯加南部陆缘与晚新生代气候变化及构造活动相关的海洋沉积物，研究团队与一项已获批资助的活塞取芯及浅地层成像科考航次开展合作。本次合作的目标是在拟选址的阿拉斯加湾钻探点位获取补充活塞岩芯与高分辨率地震成像数据。上述海洋地震数据将用于拟开展IODP钻探点位的层序地层对比与基础特征表征。本项目由美国国家科学基金会（National Science Foundation, NSF）的以下资助项目提供支持：OCE02-41828、OCE02-42084、OCE03-51043、OCE03-51062、OCE03-51075、OCE03-51089、OCE03-51096、OCE03-51620及OCE04-55183。
