I really like that there is an LED light that indicates power/whether the instrument is active.

|Application=Coastal environment: bottom mounted on a well-mixed tidal channels. River: down looking on a drifter buoy. Instrument in broadband Mode. Measure velocities in along beam coordinates using all 5 beams at 8 Hz with 1 m bin size. Also in drifting mode we uses the 5th beam for bottom tracking at 4Hz and at the same time use other 4 beams to measure velocity also at 4 Hz.

|Pros=Very low noise in measurements. Ability to capture small length scales of turbulence. We are able to observe the TKE energy cascade with a simple spectra calculation. High frequency allows for drifting approach in a fast current. Measurements are fantastic.
 +
|Cons=At the time we used the instrument, the battery estimations were not right. The battery lasted less time than expected, resulting in shorter measurement ensembles (Set up for 3 days of high frequency measurements, but only got 1 day of good ensembles)
 +
|EaseOfUse=Very simple interface to set up the instrument. Set up is very straight forward and data retrieval too. Easy to change batteries. Connection to computer is via Ethernet, can be tricky sometimes, but just have to follow steps in right order.
 +
|Software=We used the MIDAS software. Very simple interface, easy to follow steps to set up instrument and to get the data after deployment. All raw data can be exported to a .mat file for analysis. Is a very easy to read file.
 +
|Recommendations=Caution about battery estimations (Although this might been fixed)

Description

The Signature 1000 and 500 are built on the entirely new AD2CP platform, Signature1000 and Signature500 are designed for unprecedented performance in high energy turbulent environments (faster sampling), while also giving users the freedom to employ two measurement schemes at one time.


Instrument Measurements

  • 3D Velocity Profile (Current)
  • Thickness (Ice)
  • Pressure (Water)
  • Temperature (Water)
  • Directional Spectra (Wave)
  • Non-Directional Spectra (Wave)
  • Wave Height (Wave)
  • Wave Statistics (Wave)

Measurement Specifications
