Nortek’s Signature100 combines a four-beam current profiler operating at 100 kHz with an optional scientific echosounder. It is a long-range current profiler designed for combined current profile and biomass measurements
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.
