Hidden ocean heat is creeping toward Antarctica’s fragile ice shelves
Our take
Deep beneath the Southern Ocean, a significant shift is occurring as warm water gradually approaches Antarctica's delicate ice shelves. For the first time, researchers have clearly observed this concerning trend by integrating decades of ship data, robotic float measurements, and advanced machine learning techniques. Their findings reveal that a massive pool of heat, known as circumpolar deep water, has expanded and advanced toward the continent over the past two decades.
Deep beneath the Southern Ocean, a quiet but alarming shift is underway: warm water is creeping closer to Antarctica, and scientists are now seeing it clearly for the first time. By combining decades of ship data with robotic float measurements and machine learning, researchers uncovered that a massive pool of heat—circumpolar deep water—has expanded and edged toward the continent over the past 20 years.
