2025年1月5日 · Explaining the science of Antarctic glaciers. We look at ice streams, ice shelves, recent change, modern Antarctic glaciology and past glacial geology.

There are many glaciers in the Antarctic. This set of lists does not include ice sheets , ice caps or ice fields , such as the Antarctic ice sheet , but includes glacial features that are defined by their flow, rather than general bodies of ice.

The Antarctic ice sheet is a continental glacier covering 98% of the Antarctic continent, with an area of 14 million square kilometres (5.4 million square miles) and an average thickness of over 2 kilometres (1.2 mi).

2021年12月13日 · Thwaites Glacier (shown) poses the greatest near-term threat to sea level rise, scientists say. New data suggest that a buttressing ice shelf helping to slow the Florida-sized glacier’s slide...

2025年1月23日 · Antarctica - Glaciers, Seas, Ice: Antarctica provides the best available picture of the probable appearance 20,000 years ago of northern North America under the great Laurentide Ice Sheet. Some scientists contend that the initial glacier that thickened over time to become the vast East Antarctic Ice Sheet originated in the Gamburtsev Mountains ...

2021年6月16日 · This article looks at climate change and how it is affecting the glaciers in Antarctica. Glaciers and climate change are intimately linked, and the relationship is important because of the potential glaciers have to rise sea level.

2020年6月22日 · Antarctica has many different types of glacier. They range from enormous ice streams, arteries of fast flow that discharge the majority of the ice from the centre of the ice sheet to its edges [1], to slow-moving cold-based glaciers that are largely frozen to their beds [2].

2014年5月12日 · A new study by researchers at NASA and the University of California, Irvine, finds a rapidly melting section of the West Antarctic Ice Sheet appears to be in an irreversible state of decline, with nothing to stop the glaciers in this area from melting into the sea.

2019年1月30日 · A gigantic cavity – two-thirds the area of Manhattan and almost 1,000 feet (300 meters) tall – growing at the bottom of Thwaites Glacier in West Antarctica is one of several disturbing discoveries reported in a new NASA-led study of the disintegrating glacier.

2024年3月1日 · We are nearing the end of summer in Antarctica, and it's the third year in a row that sea ice there has melted to new record lows since scientists started keeping track in the late 1970s. That's...
