These unusual environments are hot spots for sea-ice production, ocean–atmosphere exchange and biological productivity. They are commonly maintained by powerful winds that push newly formed ice away from the coast, repeatedly exposing the ocean to the freezing Antarctic atmosphere.","pubDate":"Thu, 29 Oct 2026 18:20:02 EDT","url":"https://phys.org/news/2026-10-antarctic-polynyas-sea-ice.html"},"indexado":"2026-10-29T22:21:46.200Z"}}
