Marine seismic refraction

[sifick]

Hello everyone! Have someone here already worked on a Marine seismic refraction project? I would like to have some informations on seismic refraction on river or lake, the data acquisition, how do we fix the Positioning of the source and the hydrophone streamers for wach measurement Since we are on water? Is the Processing the same as the one of land seismic refraction? Thanks for the sharing!
