Source data for Figure 2 of "Microplastic fluxes transported by multiple turbidity currents through the Congo Canyon to the deep sea"

This dataset contains the numerical source data underlying Figure 2 of the manuscript “Microplastic fluxes transported by multiple turbidity currents through the Congo Canyon to the deep sea”, submitted to Communications Earth & Environment. The dataset provides measurements and estimates used to characterize turbidity-current activity, sediment properties, microplastic concentrations and microplastic transport through the submarine Congo Canyon. The Excel workbook contains five worksheets corresponding to individual panels of Figure 2: Figure 2a: Time series of velocity magnitude (m/s) measured at mooring M9 during the 2019 monitoring period. Figure 2c: Sediment grain-size measurements, including core depth, sample intervals and D10, D50 and D90 grain-size percentiles. Figure 2d: Polymer-specific and total microplastic particle concentrations (particles/kg) for sediment-trap samples ST-1 to ST-8. Figure 2e: Polymer-specific and total microplastic mass concentrations (µg/kg) for sediment-trap samples ST-1 to ST-8. Figure 2f: Estimated sediment fluxes, microplastic particle budgets and microplastic mass budgets for individual turbidity currents, including median values and 10th and 90th percentile estimates.
