Scientists are trying to understand what goes on in and around floating patches of plastic debris in the world's oceans. Results from a 22 year investigation into floating plastic garbage were published this week in the journal Science. The researchers looked at the physics behind the plastic accumulation, its concentration, and biological activity in and around the debris. Interestingly, the researchers found somewhat less plastic than they anticipated. We'll talk to one of the authors of the report about the findings.
