AI Article Synopsis

  • Evidence shows that human-induced waste significantly impacts deep-ocean ecosystems, with debris being found even in remote areas during initial explorations.
  • A study in the tropical Atlantic and Caribbean Sea recorded various types of marine debris, including plastic, metal, and glass, at depths ranging from 250 to over 6000 meters, observed using submersibles.
  • The discovery of 139 debris items—such as a ladder, clothing, and single-use packaging—highlights the severity of pollution in these deep waters and underscores the importance of understanding its effects on ocean sustainability.

Article Abstract

Evidence of anthropogenic impacts on deep-ocean systems is frequently observed, even upon the first explorations of these remote environments. One of these impacts comes from marine debris, trash that is dumped or transported into the deep ocean. Understanding the abundance and distribution of marine debris is critical to identifying holistic changes and feedbacks that influence the health and sustainability of ocean ecosystems. Here, we document widespread plastic, metal, and glass debris in deep waters of the tropical Atlantic and Caribbean Sea, observed by remotely operated and human occupied submersibles. Trash was observed from depths 250 to >6000 m. A total of 139 pieces of debris were found, including a ladder, clothing, cans, cutlery, single-use sauce packages, and a parachute. These findings further illustrate the extent of debris pollution in deep waters and the need to understand the impact of debris pollution on sustainability in Earth's largest habitat. Con frecuencia se observan evidencias de que los desechos antropógenos afectan a los sistemas oceánicos profundos, incluso en las primeras exploraciones de estos ambientes remotos. Uno de estos impactos viene de desechos marinos, basura que es tirada o transportada a los oceánicos profundos. Entendiendo la abundancia y la distribución de los desechos marinos es crítico para identificar cambios holísticos y comentarios que influencian la salud y la sostenibilidad de los ecosistemas oceánicos. En esta investigacion documentamos una extensa variedad de desechos como: plásticos, metal y vidrio en los ecosistemas oceánicos del Atlántico tropical y el Mar Caribe, observados por vehiculos robóticos controlados remotamente y ocupados por humanos. La basura fue observada desde las profundidades de 250 a más de 6000 m. Se encontraron un total de 139 piezas de desechos, incluyendo una escalera, ropa, latas, cubiertos, paquetes de salsa de un solo uso y un paracaídas. Estos descubrimientos ilustran la gran relevancia de la contaminación por los desechos en aguas profundas y la necesidad de comprender el impacto de dicha polución por desechos en la sostenibilidad en el hábitat más grande de la Tierra.
