1 Selecting site location for ADCP calibration
Site selection is an important part of the velocity measurement calibration procedure. A smooth topology of the seafloor and calm conditions as well as enough space for manoeuvring the vessel through the recommended
movement pattern is important.
Context
If you are unfamiliar with the location we recommend doing a trial run to get information about depth, maximum speed and maximum
velocity at the site. Many of the ADCP measurement problems can be solved by simply moving to a better measurement site location.
These are general requirements for an ADCP velocity measurement calibration process.
| 1 | Survey Line |
| 2 | Minimum Depth:50 m |
| 3 | Optimum Depth100 m |
| 4 | Maximum Depth: 200 m |
Procedure
| • | Select a location having a depth of approximately 100 metres. The vessel must have the space to move across the seafloor for a stretch of 3 nm or 5,5 km. In addition the vessel must be able to turn both port and starboard at the end of each stretch, using Williamson turn. |
