The Mixing Oceanographic Toolbox provides a framework to es- timate the dissipation rate and diffusivity from Electromagnetic Autonomous Profiling Explorer (EM-APEX) float observational data. The EM-APEX floats measure the temperature, salinity, pressure, and horizontal velocity of the current. Vertical gradients of velocity and buoyancy are estimated and a finescale parameterization is applied. This method provides order of mag- nitude estimates of mixing as well as estimates of the regional variability of mixing.
