McLane Moored Profiler
Autonomous profiler that travels a fixed mooring tether carrying oceanographic sensors, for depths of 30 m to 6000 m.
Description
The McLane Moored Profiler (MMP) autonomously profiles the water column along a fixed tether while carrying a selection of oceanographic sensors. Profiling depth, time intervals and pressure stops are user-defined. An optional underwater inductive modem provides real-time communication with a surface buoy or seabed node. Two models are offered; the extended MMP has 50% more battery capacity and is 12.7cm longer.
Supported sensors include Seabird 52MP CTD, Falmouth Scientific ACM, Aanderaa Optode, Satlantic SUNA Nitrate and Wet Labs ECO. MMP data is available from Ocean Observatories Initiative (OOI) arrays.
Key features
- Depth: 30 m to 6000 m (mooring dependent)
- Minimum water temp: -2°C (non freezing)
- Profiling speed: 25 cm/sec (10cm/sec, 33cm/sec options available)
- Power: 12 V primary lithium battery pack
- Battery: Standard MMP: 208 Ah battery. Extended MMP: additional 104 Ah battery
Applications
- Long-term moored time-series profiling of the water column, 30–6000 m
- Ocean observatory arrays such as the Ocean Observatories Initiative (OOI)
- Real-time data via inductive modem to a surface buoy or seabed node
