在南极冰层下发现的古代河流景观可能控制冰流并影响海平面。 Ancient river landscapes found beneath Antarctic ice may control ice flow and affect sea levels.

研究人员在南极东部冰原下发现了古老的河流景观,这可能影响目前的冰流。 Researchers have uncovered ancient river landscapes beneath East Antarctica's ice sheet, which could influence current ice flow. 这些河流系统保存了3 000多万年,可能成为自然屏障,控制冰如何向海洋移动。 These river systems, preserved for over 30 million years, may act as natural barriers, controlling how ice moves towards the ocean. 了解这些特征对于预测冰盖对气候变化的反应及其对海平面升高的贡献至关重要。 Understanding these features is vital for predicting the ice sheet's response to climate change and its contribution to rising sea levels.
