Some familiar catches, including shortfin and longfin squid, declined, while cold-water species such as mackerel bounced back from years of decline. A new study published in the Journal of Geophysical Research: Oceans finds that a pulse of cold, fresh water brought unusually cold conditions to the region, disrupting fisheries from New England to the Mid-Atlantic.","pubDate":"Tue, 20 Oct 2026 15:40:15 EDT","url":"https://phys.org/news/2026-10-cold-pulse-northwest-atlantic-reshaped.html"},"indexado":"2026-10-20T19:42:18.416Z"}}
