00:00Could microscopic plastic be changing the color of the Pacific Ocean?
00:03Scientists have discovered an unusual blue-green shift in waters
00:07surrounding the Great Pacific Garbage Patch.
00:10The finding comes from three satellite records covering 20 years,
00:13between 2002 and 2022.
00:16Researchers found that blue and green light reflected from these waters
00:20increased compared with the surrounding ocean.
00:23But what could be causing it?
00:25The team tested different explanations using computer simulations,
00:28including natural changes in microscopic algae.
00:32The blue-green pattern appeared in about 13% of simulations containing microplastics,
00:38compared with just 3% involving natural changes alone.
00:42The particles studied are smaller than a third of a millimeter.
00:45Scientists believe these tiny fragments scatter light
00:48in ways that could explain the unusual signal.
00:51However, the connection is not yet proven.
00:54Researchers still need matching water samples
00:56to confirm whether the satellite signal actually tracks plastic pollution.
01:01If confirmed, satellites could eventually help scientists
01:04monitor ocean plastic across vast areas.
