Tracing the journey of microplastics in the Arctic

By now it's well established that microplastics are a problem in the environment, even in the remotest parts of the planet. But where do different microplastics come from and how they get there, especially in the Arctic?

Sea ice

Sea ice is formed from ocean water that freezes. Because the oceans consist of saltwater, this occurs at about -1.8 °C (28.8 °F).

Sea ice may be contrasted with icebergs, which are chunks of ice shelves or glaciers that calve into the ocean. Icebergs are compacted snow and hence fresh water.

Sea ice may be deliberately created or manipulated, see Arctic geoengineering for details.
