data of microplastic abundance and mass from Figure 3 of Van Sebille et al (2015, ERL) paper

Data files of the data of microplastic abundance and mass from Figure 3 of the Van Sebille et al (2015, Environmental Research Letters, doi:10.1088/1748-9326/10/12/124006) paper
Figure 3a: maximenkomodel_abundance.csv
Figure 3b: maximenkomodel_mass.csv
Figure 3c: lebretonmodel_abundance.csv
Figure 3d: lebretonmodel_mass.csv
Figure 3e: vansebillemodel_abundance.csvFigure 3f: vansebillemodel_mass.csv
All these data sets are in either #/km2 or in g/km2. Use the area.csv (units in km2/gridcell) file to convert to #/gridcell or g/gridcell. 
Longitudes (in degrees E) and latitudes of the cell centres are also available for download; note that due to interpolation issues there are values for both 0E and 360E, in the first and last column of the mass and abundance files respectively. Sum these to get the distribution at 0E.
