Ocean microstructure data were collected using a turbulence package mounted on a light autonomous underwater vehicle (LAUV) during a cruise in February 2021, to study ocean mixing processes near a surface temperature front in the Barents Sea. The cruise onboard R/V Kronprins Haakon (KH2021702) was part of the Nansen Legacy project, funded by the Research Council of Norway. Turbulence data were collected using a modified version of a Rockland Scientific MicroRider mounted on the LAUV. Dissipation rate was measured using two airfoil shear probes. The measurements are from a 5 hour mission from 3 horizontal transects at target depths of 10, 20 and 30 m. The dataset is processed and prepared following the SCOR Working Group ATOMIX guidelines and recommendations. The provided file includes four levels: the continuous time series of full resolution data converted into physical units; the cleaned time series used for spectral analysis, wavenumber spectra and the dissipation rate estimates. Additional data from the LAUV with flight kinematics, location, temperature and salinity are also included. Further details are provided in the comments.
