There are still 2,000 miles and two weeks between us and Mauritius, with the Indian Ocean Gyre between us. We're working with another scientist from the University of Hawaii, Nikolai Maximenko, who has developed a computer model which predicts where plastic pollution might collect in the world's oceans.

To create his model he took information from 12,000 drift buoys, which have already been tracked around the world. He added what is known about currents and wind to the equation. On his map of the world, he released hypothetical drift buoys evenly across every point in the sea. Amazingly, the drift buoys migrated to the 5 gyres.

We're using the Maximenko model to plan our route through the 5 gyres. We've already been through the North Pacific Gyre and North Atlantic Gyre. After 500 miles in the Indian Ocean Gyre, we've conducted two trawls. We found plastic in each one.
