Understanding vessel-mounted current measurement
Until now, epipelagic and mesopelagic VM ADCP surveys could not deliver the resolution, precision or range to examine the ocean boundary layer in detail. To study biomass in the upper-ocean boundary layer, you had to add a separate scientific echosounder.
Nortek’s vessel-mounted Signature VM Ocean in the 100 kHz version opens up new opportunities to measure currents and to study biomass simultaneously. The 55 kHz version offers long-range current profiles with a proper precision.
