摘要

Methods and apparatuses for acquiring marine seismic data to generate images or determine properties of an interior section of the Earth using vessels ing simultaneous sources. The time required to acquire a seismic survey is decreased by increasing the speed of the source towing vessel (or decreasing the data sampling density, or increased sampling interval) using multiple simultaneous sources. After separation with simultaneous source technique and combination of separated datasets, seismic data with designed data sampling density or better are acquired.
