The objective of this project is to obtain a preliminary processed image of tapes 20 and 21. Fig. \ref{638528} shows the seismic line MGL1206_MCS_1 from which this data come. Line AB from Fig. \ref{565742} is re-named as MGL1004_MLB2 and MGL1004_MLA. The line for this project is still over the Tamu Massif and it is sub-parallel to line AB . Thus, we expect similar characteristics to the processed image shown in Fig. \ref{864959}. Fig. \ref{890265} shows the acquisition geometry for this line.
This work is organized as follows: we first present the main processing workflow applied to both tapes 20 and 21 . This workflow includes the pre-processing and the main processing parts. Pre-processing focuses on removing noise from the data for the next step. The main processing includes velocity picking on common midpoint (CMP) gathers, normal moveout (NMO) correction stacking and migration. The next discussion focuses on tape 20 where we found the major difficulties for velocity picking. We show additional processing tasks applied in an attempt to improve the final image. These tasks include re-picking velocities and Dipmoveout (DMO) correction. We also include a suggested workflow that includes DMO and pre-stack migration. Finally we present the interpretation for both tapes and the conclusions.
