Bathymetry
Bathymetry
The science of measuring depth. For surveying, dredging and underwater operations, accurate bathymetric data is critical, be it overall water depth or the location of specific instrumentation within the water column. Valeport presents a variety of integrated instrumentation packages designed to provide that high quality data, whatever the application.
Valeport's unique digital signal processing techniques use fuzzy logic to pick out and lock onto the genuine echo, while automatic power and gain control means that erroneous echoes are minimised and accurate readings can be made in water depths as shallow as 30cm. As a stand alone altimeter, this technology is ideal for integration into bathymetry packs.
Combining the technology with integral GPS receiver and on board data logging provide our echosounders with the benefits of maximum versatility and minimal deployment time. A variety of integrated instrument packages and software designed to give an online overview of density and sound velocity profiles, with industry standard resonant quartz pressure sensors being used to provide highly accurate pressure based depth readings. Valeport's own sensors and unique distributed signal processing mean that the density and sound velocity profiles are the most accurate available, whilst UNESCO standard equations are utilised to give correct data conversion between pressure and depth units.
