General Processing Description Shipboard pre-processing: The 3490-type field tapes with 2-ms sample interval were anti-alias filtered and resampled to 4 ms on board ship. The field reels were combined into individual SEGY files spanning an entire line. Numerous parts of lines were re-shot for a variety of reasons and given line name suffixes, A, B and C. Two-dimensional stacks and migrations were created on board as part of the quality control by the University of Hawaii. The basic data processing used Pardigm's Focus software. Conventional binning and initial post-stack time migrations were completed in 2001. Two processing reports are available, though both were written as internal documents to outline the processing efforts. The first discusses preliminary processing and several experiments with different binning parameters. The second explains the final binning used for the post stack migration and the background leading up to the pre-stack time migration. Both reports (ew9908.processing1.pdf and ew9908.processing2.pdf) are very large files.
