Satellite Data Hint Pacific Garbage Patch May Tint Seas Cyan

Buzzline

ScienceAlert reports that researchers at the University of Bergen examined satellite records spanning 2002–2022, finding hints that the Great Pacific Garbage Patch may tint the ocean cyan. The patch contains about 1.8 trillion plastic pieces, with microplastics accounting for 94 percent of pieces but only about 8 percent of its mass. Researchers stress that the signal is not proof, because plankton and ocean conditions also affect satellite color readings. The video covers the findings, caveats, and seawater tests planned next.

00:00The Great Pacific Garbage Patch may be changing the color of the ocean.

00:04Researchers at the University of Bergen studied satellite records from 2002 to 2022.

00:10They found hints of a cyan tint over the area where plastic collects.

00:14The patch holds about 1.8 trillion pieces of plastic.

00:18About 94% of those pieces are microplastics.

00:21Yet they make up only about 8% of the total mass.

00:25Larger items, such as fishing nets, account for most of the weight.

00:28The team stresses this is not proof.

00:31Plankton and ocean conditions can also change what satellites see.

00:35Next, the researchers plan to test seawater from the area.

00:38Ocean Color helps scientists track plankton and marine ecosystems.

00:42Disclosure. This video contains stock footage and content created or enhanced using AI-assisted tools.
