Saturday Academy

2002 Students listening to hydrophone at the HMSC pier in Yaquina Bay, Newport.

Course description
After learning a brief history and the principles of Sonar, you will make your own hydrophone and test it at the OSU pier at the Hatfield Marine Science Center. Students are encouraged to bring their own laptop PC or tape recorder so that they can record the sounds they hear inside Yaquina Bay. Using a PC and a spectrogram display, you will learn how scientists analyze the sounds generated by various mechanisms including earthquakes and marine mammals through an interactive audiovisual lecture.
