 Although it seems that the original SeaBeam Classic installation was not used much, the others were widely used, and subsequent installations were made on many vessels.SeaBeam Classic systems were subsequently installed on the US academic research vessels (Scripps Institution of Oceanography, University of California), the (Lamont-Doherty Earth Observatory of Columbia University) and the (Woods Hole Oceanographic Institution).As technology improved in the 1980s and 1990s, higher-frequency systems suitable for high-resolution mapping in shallow water were developed, and such systems are widely used for shallow-water hydrographic surveying in support of navigational charting.
