Improved turbulence-measuring systems for Navy experiments of rapidly evolving ocean flows

Abstract

Under past DURIP support, we have fabricated and tested two new technologies for measuring turbulence (the Epsilometer # #epsi# forshort # modular turbulence sensor) and small-scale flows (the travel-time velocimeter). Both of these are well suited for deployment on shipboard and autonomous platforms in order to augment our group#s capabilities for ONR and N975 experiments. In this proposal we propose to develop several key systems and subsystems to further enhance the utility of these unique instrument suites: i) an #epsi-Wirewalker# to allow turbulence to be measured from the Wirewalker wave-powered profiling vehicle; ii) the #epsideep-Solo# for autonomous measurements to 6000 m by integrating the epsi onto the MRV Systems deep Solo float; iii) the #TTV-epsifish# which will integrate our travel-time velocimeter (TTV) onto our #epsi-fish# profiling vehicle to allow small-scale velocity and turbulent kinetic energy to be measured simultaneously with turbulent dissipation rate.This abstract is publicly releasable.
