'Great Pacific Garbage Patch' worse than expected

The Ocean Cleanup, a foundation developing advanced technologies to rid the oceans of plastic, has just presented the initial findings of its Aerial Expedition -- a series of low-speed, low-altitude flights across the Great Pacific Garbage Patch, the plastic accumulation zone between Hawaii and California. Using a modified C-130 Hercules aircraft, expert spotters, and an experimental array of plastic scanning equipment, the expedition aims to accurately measure the biggest and most harmful debris in the ocean.
