Sound velocity profing from a moving vessel

摘要

Valeport Ltd, UK, and the Oceanscience Group, USA, have produced a package that could save surveyors both time and money when surveying. Traditionally performed profiles using SVPs or XBTs are the accepted method, but stopping or slowing vessels for sound velocity profiles is expensive, disruptive and time consuming. The Underway SV allows vertical sound velocity profiles to be collected in minutes without ever having to stop the vessel, with the ability to cast down to 1000 metres at four knots vessel speed, 600 metres at ten knots and 300 metres at 15 knots.
