Científicos impactados por muestra de hielo marino del Ártico llena de microplásticos

Los núcleos de huelo contienen pequeños fragmentos de plásticos

This handout photo released on August 12, 2019 by Duncan Clark/Northwest Passage Project shows an image from ice core samples containing tiny plastic fragments collected by researchers in the vicinity of the hamlet of Resolute, in Canada. - At first glance, it looks like hard candy laced with flecks of fake fruit, or a third grader's art project confected from recycled debris. In reality, it's a sliver of Arctic Ocean ice riddled with microplastics, extracted by scientists from deep inside an ice block that likely drifted southward past Greenland into Canada's increasingly navigable Northwest Passage between the Atlantic and Pacific Oceans. Plastic pollution was not a primary focus of the Northwest Passage Project, funded by the US National Science Foundation and Heising-Simons Foundation.

A primera vista, parece un caramelo duro mezclado con manchas de fruta, o un proyecto de arte de un niño de tercer grado confeccionado con escombros reciclados. En realidad, es una astilla de hielo del Océano Ártico plagado de microplásticos. Foto: AFP. (DUNCAN CLARK/AFP)

A primera vista parece un caramelo con pedacitos de fruta de colores. Pero en realidad es un trozo de hielo del Ártico lleno de microplásticos.

Un equipo de científicos extrajo esta muestra de un pedazo de hielo marino que probablemente derivó desde el norte de Groenlandia hasta el Paso del Noroeste, espacio marítimo entre los océanos Atlántico y Pacífico, cada vez más navegable debido al calentamiento global.
