Turbulence data from conductivity, temperature, and depth (CTD)-chipods on Arctic Observing Network cruise in 2020 (AON2020)

This is a turbulence dataset collected from conductivity, temperature, and depth (CTD)-chipods, a turbulence package mounted on the CTD rosette during an Arctic Observing Network cruise in 2020. The CTD stations spanned 149 casts around Alaska, USA along the northern and western shelves. Data are processed using a MATLAB software developed by the Ocean Mixing Group at Oregon State University to clean wake contamination and produce turbulence estimates. Data provided include the dissipation of temperature variance (chi) and the eddy diffusivity of temperature (Kt). Quantities are provided on a 2-meter (m) grid on the descent and ascent of the rosette. These turbulence data are meant to help diagnose and quantify heat exchanges between water masses in the subsurface and with the atmosphere.
