Instrument Short Name: EPSONDE
Instrument Description:

An EPSONDE is a tethered free-fall profiling system used to obtain temperature microstructure and velocity turbulence data in the water column. The EPSONDE profiler carries a variety of slow and fast sensors for measuring temperature microstructure, velocity microstructure, conductivity and depth. These data yield turbulent kinetic energy dissipation rates and temperature variance dissipation rates as well as derived quantities such as turbulent diffusivity.

PI supplied instrument name: EPSONDE
Dataset-specific description

An EPSONDE microstructure profile is the average of 10 deployments of the EPSONDE instrument. One microstructure profile per profile number. During Seward Johnson cruise SJ9508, 20 deployments were made during each sampling event resulting in 2 microstructure profiles per profile number.
