Description:
Oceanic turbulence is highly episodic and patchy. The persistence and long endurance of autonomous platforms provides opportunities to sample across a range of conditions and environments, and to provide access to challenging environments where ship-based measurements are often impossible.For more than a decade, a fully integrated microstructure system on Seaglider has been developed and operated by the Applied Physical Laboratory at University of Washington, using probes and analog signal conditioning boards from Rockland Scientific Inc. This compact, low-power system has minimal impact on flight and endurance of the autonomous glider, making it possible to collect extended (many months) dissipation measurements. The hardware and processing system are commercially available from Rockland Scientific as MAPLe. Microstructure measurements have been acquired over spans as long as six months, but probe failures often occur. We describe the system and present statistics for sensor durability statistics computed from deployments over a vast range of conditions and geographical locations. The field data are compared to results of probe sensitivity in long term laboratory tests.
