“Wire–Following Profiler for The Ocean Observatories Initiative: McLane Upgrades Profiler’s Communications and Electronics” highlights changes McLane developed for the commercially produced McLane Moored Profiler (MMP) to meet specs for the Ocean Observatories Initiative (OOI). The production of first-article profilers and options for additional profilers will populate the OOI’s Coastal Pioneer Array and Global Arrays.
Manufactured by McLane under the Woods Hole Oceanographic Institution (WHOI) license, the neutrally buoyant MMP autonomously profiles the water column in a time series along a fixed mooring and is driven by a magnetically coupled drive motor. Profiling depth, time intervals and pressure stops are user-defined, and profiling patterns can span specific seasons or time frames.
Many integrated sensors are available and an underwater inductive modem provides real-time communication between the profiler and a surface buoy or seabed node. Over the past decade, more than 150 profilers have been delivered and deployed around the world.
