An ice tongue or glacier tongue exists when there is a narrow floating part of a glacier that extends out into a body of water beyond the glacier's lowest contact with the Earth's crust. An ice tongue forms when a glacier that is confined by a valley moves very rapidly out into a lake or ocean, relative to other ice along the coastline.

冰舌 （英語： Ice tongue）是指 冰川 外沿探入海水的長窄條狀冰 [1]，一般由冰川上的冰沿着地表或冰面向 雪线 以下「缓慢」移动而形成 [2]。 儘管冰舌的移動速度可能很「缓慢」，但相對於其周邊冰塊，其移動速已算是快速 [3]。 冰舌作為 冰河 或 山谷冰川 的延伸部分，常常会伸入 海洋 或者 湖泊 中 [2]。 比較著名的冰舌有 厄瑞玻斯冰舌 （英语：Erebus Ice Tongue） 和 德里加爾斯基冰舌。 這兩座冰舌位處於 南极洲 羅斯島 上兩條不同的冰川之上。 ^ 北極之最：格陵蘭史帕特冰 …

2018年5月23日 · The term ice tongue refers to a geographic phenomenon in which a narrow section of ice forms and projects directly out from the shoreline and into a nearby body of water, such as a lake, sea, or ocean. Typically, ice tongues protrude from the bottom of glaciers, at the point where the glacier runs into open lake or ocean waters.

2022年2月7日 · Ice tongues are simply floating platforms of ice which are attached to the front of marine-terminating glaciers and extend into the sea. Ice tongues differ from ice shelves as they are confined by valley walls and have a narrow width relative to their length, hence their name (1).

The Drygalski Ice Tongue in East Antarctica is 140 km long, with 90 km of this extending unconfined into the Ross Sea. The ice tongue has important implications for the surrounding area, influencing the local ocean and contributing to the formation of the Terra Nova Bay Polynya.

When an ice shelf is narrower than the bay it occupies, it is sometimes called an ice tongue. Ice shelves fall into three categories: Ice shelves fed by glaciers; Ice shelves created by sea ice and local snowfall; Composite ice shelves; Glacier outflow is the most common source of …

2023年1月9日 · Observations and modelling of the Thwaites Glacier Ice Tongue link episodic changes in ice speed to fracturing between 2015 and 2021 and show these changes to be reversible over one- to...

The Drygalski Ice Tongue, Drygalski Barrier, or Drygalski Glacier Tongue is a glacier in Antarctica, on the Scott Coast, in the northern McMurdo Sound of Ross Dependency, 240 kilometres (150 mi) north of Ross Island.

2024年2月20日 · The 79 North Glacier features Greenland’s largest floating ice tongue, which has been thinning from below in the last few decades. Here, the drivers of the upward trend and interannual ...

Ice tongues and ice shelves are the seaward floating extensions of glaciers, draining interior continental ice into the ocean. While ice shelves tend to be in embayments and are therefore in contact with the coastline, ice tongues are long and narrow, extending far beyond their con-nections to land.
