Resolving multi-scale mixing processes and their impacts using a twin tow-yo microstructure profiling system

A free-fall tow-yo turbulence profiler, Underway-VMP (UVMP), and a free-fall tow-yo biochemical profiler that can measure nitrate concentrations necessary for phytoplankton growth in the field using ultraviolet light have been developed and observation methods established. Observations using these profilers showed that turbulence 100-1000 times larger than typical thermocline values were seen over 100 km, and the results were published in Comm Earth & Environment in 2021. These observations were used again in the Tokara Strait in September 2020 and showed that the Kuroshio Current flowing south of Kyushu is a very large turbulence and nutrient hotspot.
