2 The First Sonars Sperm whale (Physeter macrocephalus) Killer whale (Orcinus orca)
3 Underwater Sound Leonardo da Vinci (1490) using a tube you will hear ships at a great distance
4 Measuring Speed of Sound Colladon and Sturm (1826), Lake Geneva, Switzerland 18 km Sound speed estimate: 1435 ms -1 Δ = 4 ms -1 from current values
5 20 th Century Use of Sound To fathom the ocean Lieutenant Maury,US Navy (1859)
