Antarctic tundra occurs on Antarctica and on several Antarctic and subantarctic islands, including South Georgia and the South Sandwich Islands and the Kerguelen Islands. Most of Antarctica is too cold and dry to support vegetation, and most of the continent is covered by ice fields or cold deserts.
One of the planet's most recent biomes, a result of the last ice age only 10,000 years ago, the tundra contains unique flora and fauna formed during the last glaciation in areas unrestricted by permanent ice. The tundra region is found in high latitudes, primarily in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, as well as the ...

At higher elevations this ecoregion has a tundra climate (Köppen ET ) with cold summers and very cold winters. Annual precipitation ranges from about 2,000 mm (79 in) to over 7,000 mm (280 in), the majority of which falls as snow. The mean annual temperature is -0.5°C (31.1°F), with an average summer temperature of 10°C (50°F) and an ...
Apart from Alaska, around 1330 glaciers, 1175 perennial snow fields, and 35 buried-ice features have been identified. [ 2 ] [ 3 ] This is a dynamic list and may never be able to satisfy particular standards for completeness.
Ice fields are formed by a large accumulation of snow which, through years of compression and freezing, turns into ice. Because of the susceptibility of ice to gravity, ice fields usually form over large areas that are basins or atop plateaus, thus allowing a continuum of ice to form over the landscape uninterrupted by glacial channels.
Wet tundra along with Sitka spruce and Western hemlock forests are mainly found in the Lower bay. In the Upper bay there are tidewater glaciers and from the newly deglaciated land are the post-glacial meadows. In the peaks of Glacier Bay are Alpine tundra, glaciers and ice fields. [29]
The area has tundra, Arctic vegetation, [3] glaciers, and, for most of the year, is covered in thick blankets of snow and ice. [5] It is home to various species of plants, and land, air and marine animals. [6] Due to the severe weather conditions, the region's flora and fauna has had to adapt to survive. [6]
