Transoceanic microplastic surveys in the present study. The survey stations along a meridional transect from Sta. 1 to Sta. 38 are shown by red dots (a). Areas with a dense network of stations are enlarged in the inset maps. The stations used in Reisser et al.22 are shown by green dots, which complement the large gap between stations 15 and 16. The weight concentrations of microplastics in Goldstein et al.3 were also used in the present study within the area surrounded by the broken lines (b)
