For first time in 40 years, deep water off Panama's coast hasn't risen: ocean system appears to be on verge of collapse
For more than four decades, the ocean along Panama's Pacific coast followed a precise and reliable rhythm. Between January and April, cold, nutrient-rich water masses rose from the depths, feeding the marine food chain and protecting coral reefs and local fisheries. In 2025, however, this mechanism came to a sudden halt. The Panama upwelling didn't take place, leaving scientists without historical references and questioning the stability of tropical ocean systems.
