This dataset shows the global distribution of over 1,300 estuaries, including some lagoon systems and fjords. The majority of estuaries are represented by polygons, except for 44 records for which points are available. This dataset was developed by Sea Around Us (www.seaaroundus.org).

Every year, millions of tons of plastic enter the oceans, of which the majority spills out from rivers. A portion of this plastic travels to ocean garbage patches, where it gets caught in a vortex of circulating currents alongside plastic from other sources (e.g. offshore fishing activities). If no action is taken, plastic will increasingly impact our ecosystems, health, and economies. The Ocean Cleanup is a non-profit organization developing and scaling technologies to rid the oceans of plastic. To achieve this objective, we have to work on a combination of closing the sources of plastic pollution and cleaning up what has already accumulated in the ocean and doesn’t go away by itself. This goal means we plan to put ourselves out of business – once we have completed this project, our work is done. To rid the oceans of plastic, we need not only to clean up what is already out there but also stop new plastic from entering the ocean – we need to close the tap. Working together with government leaders, individuals, and private corporations, our goal is to tackle these 1000 most polluting rivers all over the world Every single year, marine plastic costs the economy (6 to 19) billions of dollars – impacting tourism, fisheries and aquaculture, and (governmental) cleanups. And that doesn’t include the impact on our health and on the marine ecosystem. Intercepting plastic in rivers is much more cost-effective than dealing with the consequences downstream.
