Rockland Customers Tow-Yow-ing the VMP-250

Rockland Scientific instrument users continue to push the operational boundaries of microstructure turbulence measurements.  A sub-section off these microstructure data collection trailblazers have been developing “tow-yow-ing” techniques with the VMP-250 to gather underway profiles in the mixed layer. 1.

A Method for Determining Mixing Rates from Concurrent Temperature & Velocity Measurements

Ocean mixing has historically been estimated using Osborn’s model by measuring the rate of dissipation of turbulent kinetic energy and the background density stratification N while assuming a value of the flux Richardson number, Rif. A constant Rif of 0.17 is typically assumed, despite mounting field, laboratory, and modeling evidence that Rif varies. This challenge […]
