Nortek Signature 100K Hz Frontview Dypetset

CURRENT PROFILER

Signature100

Long-range current profiler designed for combined current profile and biomass measurements

Highlights

  • 300–400 m current profiling range
  • Optional center beam with 70–120 kHz echosounder

Overview

  • The Signature100 combines a four-beam current profiler operating at 100 kHz with an optional scientific echosounder.

    Both the current profiler and the biomass measurements have an effective range of 300-400 m providing unprecedented insight into the dynamics of zooplankton, krill or even schools of fish. Likewise, acoustic tracer material can give new insight into small-scale physical processes.

Applications

  • Detection of krill in the water column
  • Cost-effective current profile measurements at mid-range
  • Plankton migration studies
  • Upwelling and downwelling studies
  • Internal waves
  • Suitable for buoy mounting with internal AHRS
