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. Funded by NSF grants OCE02-41828, OCE02-42084, OCE03-51043, OCE03-51062, OCE03-51075, OCE03-51089, OCE03-51096, OCE03-51620, and OCE04-55183.

作为一项旨在针对南部阿拉斯加边缘晚新生代气候变化和构造活动相关海洋沉积物进行钻探的IODP项目现场调查的一部分，研究人员与已获资助的活塞取样和浅层成像巡航项目携手合作。其目的在于获取更多拟议的阿拉斯加湾钻探位置的活塞岩心和高清地震图像。海洋地震数据将被用于地层对比分析和拟议IODP钻探位置的基线特征描述。该项目由NSF资助，资助编号分别为OCE02-41828、OCE02-42084、OCE03-51043、OCE03-51062、OCE03-51075、OCE03-51089、OCE03-51096、OCE03-51620和OCE04-55183。
