Underway Profilers

High Quality CTD and Sound Velocity Profiles

Oceanscience underway profiling systems are the most compact and versatile options available to oceanographic researchers and hydrographic surveyors. The UnderwayCTD and UnderwaySV offer research quality conductivity, temperature, depth (CTD) or sound velocity (SV) profiles from 15m to 1000m depth, while underway at up to 20kts.

Improve Efficiency - Profile on a Moving Ship

Stopping an oceanographic research vessel to occupy a fixed CTD station or suspend a hydrographic survey to perform water column sound velocity profiling can come at a substantial cost in terms of vessel productivity. Our UnderwayCTD and UnderwaySV profiling systems eliminate the need to stop your vessel for upper ocean profiling. Data quality similar to stationary casts can now be obtained while fully underway. Innovative freefall probe systems designed in partnership with industry leaders SeaBird Electronics (USA) and Valeport Ltd (UK), deployed with our revolutionary compact deployment system now offers researchers and surveyors the profiles they need, with no loss of ship time.
