Particle fluxes across three surface types for the expedition ARTofMELT

DOI

During the ARTofMELT Arctic Ocean expedition in spring 2023, turbulent particle fluxes were continuously measured aboard the icebreaker Oden to investigate the spatial and temporal variability of particle sources and sinks over three surface types. Between 10 May and 12 June 2023, turbulent fluxes were measured using a uSonic-3 sonic anemometer and a mixing-type condensation particle counter (MCPC 1720) operated at 20 Hz, with the inlet mounted next to the sonic anemometer on the foremast at 20.3 m height. Additional supporting data include particle number size distributions, meteorological data, and automated ship-based camera images for surface-type classification. Surface conditions were divided into three categories—closed ice, narrow leads, and open water—based on hourly images. Two stationary ice camps at 79.6° N, 1.3° W and 79.8° N, 2.8° E, as well as measurements collected while drifting or transiting, provide spatial coverage between 78–81° N and 4° W–6° E. All data were first pre-processed through motion correction, inlet-loss correction, determination of the time lag, and filtering of ship-exhaust pollution. 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, particle concentrations and surface conditions in the central Arctic during the early melt season.
