Autonomous Profiling EM-Apex Floats for the ARCTERX DRI
Abstract
EM-Apex profiling floats excel at collecting measurements of vertical shear in the upper ocean at spatial scales that can capture b oth internal waves and submesoscale currents. These shear profiles are used to generate profiles of velocity and are taken coherentl y with measurements of temperature, salinity, and thermal dissipation rate (chi), which can be used to estimate turbulence. Collecti ng these measurements would greatly support the goals of the upcoming ONR Island Arc Turbulent Eddy Regional Exchange (ARCTERX) Depa rtmental Research Initiative (DRI), where one of the aims is to understand the submesoscale energy cascade, including the interactio n between submesoscale currents and internal waves. This proposal would support the acquisition of 8 EM-Apex floats and the in-house modification of these floats to include microstructure systems. The floats would contribute to both the process cruises and long-te rm deployment of profiling floats in the ARCTERX DRI, expanding the abilityof the DRI to address the science objectives.
