Dissipation measurements from a Slocum glider in the Lofoten Basin, September 2017.

Ocean microstructure measurements were obtained from a Rockland Scientific (RSI) MicroRider attached to an electric Slocum glider. Data were collected during the cruise KB2017618 onboard R.V. Kristine Bonnevie, as a part of the PROVOLO (Watermass transformation processes and vortex dynamics in the Lofoten Basin of the Norwegian Sea) project, funded by the Research Council of Norway (project number 250784).
The glider mission started on 6 September 2017 outside of the Lofoten Vortex, a permanent anticyclonic eddy in the Lofoten Basin of the Norwegian Sea. The glider was then navigated into the core of the eddy until the mission ended on 12 September 2017. In addition to the turbulence package, the glider was equipped with an unpumped Seabird conductivity-temperature (CTD) sensor, a Wetlab ECO-puck (fluorescence and turbidity), and an Andreraa oxygen optode. All instruments were configured to sample during dives and climbs of the glider.
The dissipation rate was measured using two airfoil shear probes. Turbulence channels sampled at a rate of 512 per second, and the slow channels at 64 per second. The dataset has been processed and formatted in accordance with the SCOR Working Group ATOMIX guidelines and recommendations. One NetCDF (NC) file per instrument's native file is provided (typically one file between consecutive surfacings of the glider, 106 files in total). Each provided NC file is organized in four hierarchical groups including continuous time series of data converted into physical units, cleaned time series used for spectral analysis, wavenumber spectra, and dissipation rate estimates. The first group also includes time series, matched with the MR time, of longitude, latitude, temperature, salinity, dissolved oxygen concentration, turbidity, chl-a fluorescence, and flight parameters from the glider (so-called hotel).
The grouped NC files are large and may be impractical to download and merge. For users only interested in the dissipation estimates and other time-averaged profiles, we also provide two separate NC files with all dissipation rate (and other related parameters) profiles and 1-s averaged sensor data, including flight parameters, collated into one file each.
