A technology to measure deep turbulence mixing by an expendable microstructure profiler

The measurements of turbulence in the deep ocean, especially close to bottom, are extremely sparse due to the difficulties of obtaining measurements at these depths. Recently, we have developed a new technology, using an expendable instrument (VMP-X, Vertical Microstructure Profiler - eXpendable), that is depth rated for 6000 m, and thus is able to reach the sea bottom and capable of measuring boundary mixing.
