HONOLULU (AP) - Thirty boats left Hawaii recently on a unique mapping mission: To record the size and location of the plastic garbage over 1.4 million square miles of the Pacific Ocean.
The Honolulu Star-Advertiser reports that the project, called the Mega Expedition, is part of a larger effort to eventually clean up what's known as the Great Pacific Garbage Patch.
The boaters will use GPS and a smartphone app to search for and record pieces of plastic.
The mapping effort is sponsored by The Ocean Cleanup, a Dutch organization founded by then-18-year-old Boylan Slat. According to the group, the data on plastics in the Pacific gathered over the next three weeks is expected to be more than has been gathered in the past 40 years.
