A tiny shark tooth, part of a mantis shrimp and microscopic marine organisms reveal that as the Andes rose, the Western Amazon sank twice, each time for less than a million years. Water from the Carib...
Scientists are trying to predict the future behavior of El Niño -- the formation of warmer-than-usual ocean waters in the equatorial Pacific -- by looking back in time.This week, the journal Geol...
At high latitudes, such as near Antarctica and the Arctic Circle, the ocean’s surface waters are cooled by frigid temperatures and become so dense that they sink a few thousand meters into the ocean’s...

About 2000 kilometers east of the Philippine Islands lies one of the most famous topographical peculiarities of the oceans: the Mariana trench. Reaching depths of up to 11,000 meters below sea level, ...
2017年1月23日,国际著名期刊《自然-地球科学》(Nature Geoscience)以长篇论文(Articles)形式在线刊登中科院海洋研究所张国良研究员(第一/通讯作者)的论文:“Evolution of carbonated melt to alkali basalt in the South China Sea”,报道了在中国南海发现世界首例由碳酸盐质母岩浆向碱性玄武岩连续转化的现象。...
New evidence involving the ancient poop of some of the huge and astonishing creatures that once roamed Australia indicates the primary cause of their extinction around 45,000 years ago was likely a re...
The present-day thinning and retreat of Pine Island Glacier, one of the largest and fastest shrinking glaciers of the West Antarctic Ice Sheet, may have already been underway as early as the 1940s, ac...
Three recent publications by early career researchers at three different institutions across the country provide the first look into the biogeochemistry, geophysics and geology of subglacial Lake Whil...

If you think rivers are what send terrestrial rainfall back into the oceans, you don’t know the half of it. And that fraction keeps shrinking. According to new research, it might be that only one-fift...
Seafloor sediment cores reveal abrupt, extensive loss of oxygen in the ocean when ice sheets melted roughly 10,000-17,000 years ago, according to a study from the University of California, Davis. The ...
据英国《卫报》报道,一个科学家小组向美国国会报告时警告称,如果气温上升2-7℃时,格陵兰的整个冰层都将从世界地图上消失,冰盖消亡将造成全球海平面上升7米,进而对世界上其他地区造成严重影响。
美国冰雪资料中心首席科学家泰德-斯坎伯博士5月20日发表运用福卫二号拍摄两极冰河获得的资料,语出惊人地预估,2020至2025年北极海冰、2100年南极海冰都将完全消失。
美国国家海洋和大气管理局研究人员4月3日公布研究报告称,北极地区的夏季海冰融化速度之快超过了原先预期,其面积最早可能在30年内大大减少,而此前曾有研究预计本世纪末才会发生上述现象。
似乎破纪录般的海冰消失和永久冻结带融化还嫌不够,气候变化如今正在对北极圈毗邻的海岸造成影响。新的研究表明,在过去52年中,美国阿拉斯加州东北海岸线遭侵蚀的速度增加了一倍。这种北极海岸线的退化很可能对当地的生态系统、生活在北极圈的居民以及石油与天然气的开采构成巨大影响。
