Description

Until now, ADCP current surveys have been complex and time-consuming processes. A successful current survey depends on highly skilled personnel and the hardware set-up is unique, and challenging, for each vessel.             
This leads to concerns regarding  interfacing, synchronization, offsets and mounting. A miscalculation in connection with any one of these factors can lead to errors that affect the final velocity data quality.

Nortek’s vessel-mounted ADCP current survey package – called Signature VM – opens up new and unprecedented opportunities to the community, while offering operational convenience and reduced complexity. Data quality can be safeguarded, and both errors and initial installation time can be substantially reduced by using an integrated system where each is module is pre-qualified.
