This data is based on the following sources

Eriksen et al. – Plastic pollution in the world's oceans: more than 5 trillion plastic pieces weighing over 250,000 tons afloat at sea

Estimates by Eriksen et al. (2014) on the number of plastic particles of surface ocean debris floating at sea, differentiated by ocean basin and particle size.

Particle size categories range from small microplastics to macroplastics.

Estimates are based on results from 24 expeditions (over the period 2007–2013) across all five sub-tropical gyres, costal Australia, Bay of Bengal and the Mediterranean Sea conducting surface net tows (N = 680) and visual survey transects of large plastic debris (N = 891). These field-based results were combined with oceanographic modelling of floating debris dispersal and wind-driven vertical mixing to derive total oceanic figures.

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.

At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.
