LOCATIONĭue to seasonal and interannual variabilities of winds and currents, the GPGP’s location and shape are constantly changing.
Sampling at different locations within the same time period allowed a more accurate estimate of the size of the patch and the plastic drifting in it. This consisted of a fleet of 30 boats, 652 surface nets and two flights over the patch to gather aerial imagery of the debris.
To formulate this number, the team of scientists behind this research conducted the most elaborate sampling method ever coordinated. The Great Pacific Garbage Patch covers an estimated surface of 1.6 million square kilometers
