Claim Text:
1. A method of marine seismic exploration or surveillance, comprising: selecting a first seismic source, said first seismic source comprising a swept-frequency source; determining at least an approximate bandwidth of said seismic source; using at least said approximate bandwidth of said seismic source to determine a source depth such that substantially all of said bandwidth falls between a first ghost notch and a second ghost notch wherein said first ghost notch and said second ghost notch each may be any one of the notches occurring at regular intervals of frequency except for a zero frequency ghost notch, said source depth comprising a source depth of 25 meters or greater, thereby creating a survey plan; and, collecting at least one seismic trace by activating said first seismic source according to said survey plan.
