新的南极地图揭示了冰层下数千处隐藏的陆地形态,改进了气候和海平面预测。 A new Antarctic map reveals thousands of hidden landforms beneath the ice, improving climate and sea-level predictions.

2026年1月15日发表在《科学》上的南极冰川地下地形高清晰度地图显示,利用卫星数据和称为冰流扰动分析的新模型技术,在冰下发现了数以万计的以前未知的山谷、山脉和通道。 A new, high-resolution map of Antarctica’s subglacial terrain, published in Science on January 15, 2026, reveals tens of thousands of previously unknown valleys, mountains, and channels beneath the ice using satellite data and a new modeling technique called Ice Flow Perturbation Analysis. 该地图以2至30公里的大小为特征,提高了对冰流和如何应对气候变化的理解,有助于对海平面上升作出预测。 The map, which captures features from 2 to 30 kilometers in size, improves understanding of how ice flows and may respond to climate change, aiding sea-level rise projections. 这项研究虽然在探测较小或更大的陆地形态方面有限,但标志着极地科学的一大进步,突出了未来调查的重要性。 While limited in detecting smaller or larger landforms, the study marks a major advance in polar science and highlights the importance of future surveys.
