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.

在针对拟议中的IODP项目，对与上新世晚期气候变化及南部阿拉斯加边缘构造活动相关的海洋沉积物进行钻探的现场调查过程中，研究人员与一项已获资助的活塞取心及浅层成像巡航项目联合协作。其目的在于获取额外的活塞岩心和拟议中的阿拉斯加湾钻探地点的高分辨率地震图像。所获得的海洋地震数据将用于地层序对比分析以及拟议中的IODP钻探地点的基线特征描述。该项目由NSF资助，资助编号包括OCE02-41828、OCE02-42084、OCE03-51043、OCE03-51062、OCE03-51075、OCE03-51089、OCE03-51096、OCE03-51620以及OCE04-55183。
