Now The Indian Ocean Has Its Own Garbage Gyre, Too

[hatrack]

Scientists previously mapped huge floating trash patches in the Pacific and Atlantic oceans, but now a husband-wife team researching plastic garbage in the Indian Ocean suggest a new and dire view. "The world's oceans are covered with a thin plastic soup," says Anna Cummins, cofounder of 5 Gyres Institute.

Cummins and her husband, Marcus Eriksen, established the 5 Gyres Institute to research plastic pollution in the world's oceans. The team works in collaboration with Algalita Marine Research Foundation and Pangaea Explorations, two nonprofit scientific organizations devoted to marine preservation. They report that all of the 12 water samples collected in the 3,000 miles between Perth, Australia, and Port Louis, Mauritius (an island due East of Madagascar), contain plastic.

Their findings support earlier research about trash washed onto beaches in and around the Indian Ocean, and it's already been well established that there's an enormous amount of plastic trash swirling in the North Pacific and North Atlantic Ocean Gyres.

Gyres are powerful rotating currents in the world's major oceans. The five large subtropical gyres are located in the North Pacific, South Pacific, North Atlantic, South Atlantic, and Indian oceans. Once plastic makes its way into the ocean (through sewers, streams, rivers, or from the coast), it is ultimately swept up and trapped in these gyres and forms a swirling soup of garbage. "There is no island of trash," says Anna Cummins, cofounder of 5 Gyres Institute. "It's a myth." Instead, she says the garbage patches resemble plastic soup or confetti. "We now have a third accumulation zone of plastic pollution that shows compounding evidence that the trash isn't condensed to an island," she says. "It's spread out across the entire gyre from coast to coast."

Ironically, it would be far easier to clean up the oceans if the trash were forming islands, Eriksen explains. In his opinion, it isn't practical to try to recover the plastic from sea because most is fragmented and widely distributed. "If you stand on island beaches and mainland coastlines, you can watch the plastic coming to you. That's where gyre clean up makes the most sense," Eriksen says, "but we need to stop the flow of plastic into the ocean."
