Our team would like to give a very special thanks to Chris Sturtivant and Loughbrough University without whose help this site would never have been created. All sound files and almost all images used in the creation of this site have come from their sources and have been used with their permission**. If not for the help of Mr. Sturtivant this site would never have been completed. Again thank you Mr. Sturtivant and all those at the Under Water Acoustics Group at Loughbrough University.
