iXblue Pty Ltd (formerly IXSURVEY) Senior Surveyor, Rhys Davies discusses the variables which affect how sound travels through fresh water and salt water and why that affects the accuracy of survey data. He demonstrates the two Sound Velocity Probes (SVP) iXblue Pty Ltd uses to measure sound speed and travel time in shallow and deep water.
