1. A method for correcting a swell effect and a mis-tie at the intersection point of marine seismic data using multi-beam echo sounder data measured by a multi-beam sounder, the method comprising:
receiving the multi-beam echo sounder data;
extracting water depth values corresponding to positions having latitude and longitude coordinate points same as shot points at the marine seismic data in the multi-beam echo sounder data;
correcting the swell effect and the mis-tie at the coordinate points of the marine seismic data by reflecting the water depth values; and
deriving the marine seismic data at which the swell effect and the mis-tie are corrected by performing the extracting and the correcting on all coordinate points at the marine seismic data.
