Deep canyons reveal pollution and life

A single deep‑sea canyon expedition (Mar del Plata, Aug 2025) discovered 57 new species and recovered shoes, plastic bags, and fishing gear at abyssal depths, showing that these remote habitats both host undescribed biodiversity and act as sinks for human debris. This twin finding reframes deep canyons as simultaneous frontiers for discovery and indicators of the global reach of pollution. — Highlights that ocean conservation and pollution policy must account for remote deep‑sea habitats that are both biologically important and already affected by human refuse.
