The MMP autonomously profiles the water column in a time-series along a fixed tether. Profiling depth, time intervals and pressure stops are user-defined, and profiling patterns can span specific seasons or timeframes. An optional underwater inductive modem provides real-time communication between the MMP and a surface buoy or seabed node. The MMP can be configured with a range of sensors, of which Nortek Acoustic Doppler Current Meteris a new option.
When integrated with the MMP the Nortek Acoustic Doppler Current Meter features:
- Acoustic Doppler technology, allowing for the remote measurement volume to be located up-stream of the MMP and outside of the any flow disturbance.
- Four-beam transducer head, controlled by the MMP to use only three acoustic beams at a time to reduce power and always sample in undisturbed flow when the MMP is ascending and descending the wire.
- Upgradable to High Resolution (HR) profiler mode for advanced turbulence measurements.
- Sample a single cell (current meter mode), with sampling rate up to 10 Hz.
- 1000 m pressure rating.
- A low-profile shape which protects the current meter from damage during deployment and recovery, as well as from debris at sea.
McLane offers two MMP models: the standard and extended version. The extended MMP provides 50% more battery capacity than the standard MMP.
