Using Geographical Information Systems (GIS) from Google Earth and ArcGIS by Esri, Algalita researchers have developed a variety of ways to present information about the presence of plastic in the world’s oceans. While data is collected and analyzed in various ways, our map focuses on representing the count density of plastic per cubic meter of water for Manta trawl samples only. The inclusion of new data will be added as soon as it becomes available, so check back often.
