Researchers involved in a new study suspected that much of the Arctic's plastic pollution must be coming from distant sources due to the small size of the debris and the region's low population To test this, they retraced the debris' possible path to the Arctic using data from 17,000 satellite buoys spread across the world's oceans. The data revealed that floating plastic gets caught up in the North Atlantic in a stretch of a deep-ocean current called the thermohaline circulation. [Source: Grand Forks Herald]
