Nortek Signature VM Coastal

Also known as

  • Signature250 VM Coastal

Nortek Signature VM Coastal is a Norwegian vessel-mounted acoustic Doppler current profiler package for vessel-of-opportunity surveys in rivers, deltas, coastal waters, ports, harbors, discharge sections, and mixing studies. Nortek frames the package around Signature 1000, 500, or 250 kHz ADCP instruments, a fairing bracket, GNSS satellite compass, compact processing unit, and acquisition/review software, with the lower-frequency 250 kHz lane extending the coastal family toward 200 m profiling contexts.

Nortek identifies VM Coastal as a vessel-mounted ADCP package, while NOAA describes ADCPs as acoustic instruments that measure current speed and direction through the water column from moving or fixed platforms.

Nortek's Signature55 VM Ocean update places the 55/75 kHz and 100 kHz VM Ocean options beside the VM Coastal 1000, 500, and 250 kHz product series, distinguishing longer-range ocean profiling from shorter-range coastal and lower-depth profiling.

Teledyne RD Instruments, Nortek, NOAA, NASA, and USGS sources document ADCPs as shipboard, moored, seafloor, buoy, vehicle-mounted, and river-discharge instruments, with the cataloged Haixun 08 fit showing how this commercial sensor class appears in a hydrographic survey-vessel suite.
