Preventing biofouling on ADCPs deployed in the field
Biofouling is a problem that may not come top of all marine scientists’ priorities when preparing underwater instruments for deployment. However, in…
Providing critical metocean data for a major offshore gasfield installation
Nortek’s Aquadopp 600 kHz current profiler provided valuable information on sea conditions during the installation of a Malaysian offshore gas…
Improved metocean data accuracy with a buoy-mounted ADCP
The collection of wave height and period, sea level and meteorological data on metocean buoys has been a vital part of the researcher’s and…
Shallow-water current measurement in intertidal creeks made easy
Australian hydrographic survey company Precision Hydrographic Services (PHS) deployed multiple Nortek Eco current profilers in creeks in northwest…
Using a versatile vessel-mounted ADCP to obtain high-resolution current data in estuarine and near-shore environments
The Signature 250 is the lowest available frequency of the Nortek's Signature VM Coastal series (250 kHz). Designed to sample in depths of up to 200…
Performance evaluation of an ADCP combined with a scientific echosounder
Echosounders are widely used to quantify fish behavior, fish stocks and zooplankton biomass. Acoustic Doppler Current Profilers have also been used…
A DVL that brings navigation accuracy to tank inspection robots in a harsh environment
The versatility of Nortek’s DVL is spotlighted by its integration on a pioneering autonomous robot that is revolutionizing fuel tank inspection while…
Deploying a vessel-mounted ADCP on a USV to survey currents in a complex river environment
If a river crossing can be mapped using a USV instead of field personnel, then the risk to life is considerably reduced. Ultrabeam Hydrographic…
