iXblue 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 uses to measure sound speed and travel time in shallow and deep water.
The mini SVP, which can be used when a vessel is stationary is deployed on smaller boats in shallow water. When working in deeper water and on larger boats, the larger Underway SVPs are used to save time and cost.
