| contents | During the ARTofMELT Arctic Ocean expedition in spring 2023, turbulent particle fluxes were continuously measured aboard the icebreaker Oden in order to investigate the spatial and temporal variability of particle sources and sinks across three different surface types. Between 10 May and 12 June, turbulent fluxes were measured using a uSonic-3 sonic anemometer and a 20 Hz mixing-type condensation particle counter (MCPC 1720), with the inlet mounted next to the anemometer on the foremast at a height of 20.3 metres. Additional supporting data included particle number size distributions, meteorological data and automated, ship-based camera images for surface type classification. Surface conditions were categorised as closed ice, narrow leads or open water based on hourly images. Two stationary ice camps, located at 79.6° N, 1.3° W and 79.8° N, 2.8° E, as well as measurements collected while drifting or transiting, provided spatial coverage between 78° N and 81° N, and 4° W and 6° E. All data were pre-processed using motion correction, inlet-loss correction, time lag determination, and ship exhaust pollution filtering. Turbulent particle fluxes were then calculated using standard eddy covariance methods with a 20-minute averaging interval. This dataset provides a comprehensive record of turbulent particle fluxes, concentrations of particles, and surface conditions in the central Arctic during the early melt season. |
