Welcome to AntarcticGlaciers.org
Antarctic glaciers are beautiful and awe-inspiring. They affect us through their connections with the ocean and sea level, and environmental change is having rapid consequences in Antarctica.
Antarctica is the world’s largest ice sheet, covering ~14,000,000 km2. Much of the Antarctic ice sheet surface lies above 3000 m above sea level. This massive thickness of ice drowns whole mountain ranges, and numerous volcanoes exist underneath the icey exterior. Antarctica is the world’s fifth largest continent, and it is, on average, the highest and coldest continent.
Antarctica provides a unique record of the Earth’s past climate, through the geomorphological record of glacier moraines, through ice cores, through deep sea sediment cores, and through past records of sea level rise.

Geography resources for school students
This website aims to introduce some key concepts in Antarctic glaciology and glacial landscapes and systems more broadly. The Geography Students section includes a detailed compilation of Resources for Teachers.
Antarctic StoryMap Series
There is a series of dedicated four Antarctic StoryMap Collections that are designed for use in the classroom by UK Key Stage 3/4 students (age 14 upwards) here. This series introduces the Antarctic Biome through 18 interactive StoryMaps. Each StoryMap should take around an hour to work through, so together, they are a comprehensive scheme of work. A scheme of work for teachers is provided for each collection.
There are four StoryMap Collections:
- Salliy Wedding Hair Comb Gold Leaf Bridal Hair Piece Silver Rhin
- Antarctica’s wildlife
- Stellar Technical 21-100-22 Classic 100 Gel Flux - 8 Oz
- People in Antarctica
Webpages for post-16 education
These relevant ideas are explored in our Science Themes, and include descriptions of different types of glacier, ice shelves, and ice streams. This website also explores the recent rapid environmental changes happening today in Antarctica, and how changes in atmospheric and ocean temperatures has led to ice-shelf collapse, rapid glacier recession and sea level rise.
The Antarctic Continent
The Antarctic continent comprises three ice sheets: the Antarctic Peninsula Ice Sheet, the West Antarctic Ice Sheet, and the TURKISH SWAN LAMPS. Most of Antarctica is covered by ice (~98%), with ice-free areas on, for example, nunataks (high mountains poking through the ice sheet), James Ross Island and Alexander Island on the Antarctic Peninsula, and the McMurdo Dry Valleys in East Antarctica.
The Antarctic Ice Sheet is drained by fast-flowing ice streams, which respond quickly to climate change; they can thin, accelerate, recede, or even stop flowing entirely. Beneath the thick skin of ice, there is flowing water and subglacial lakes. Despite the aridity and cold temperatures, there is life on the ice, in the ice and underneath the ice.
Antarctic glaciers terminate on land or in the sea, as floating ice shelves or grounded or floating outlet glaciers. The Antarctic Ice Sheet contains 25,400,000 km3 of ice, which, if it melted, would be equivalent to a sea level rise of 58 m. The ice sheet is over 4000 m thick in places, and in places, the West Antarctic Ice Sheet is grounded more than 1500 m below sea level. The coldest temperature ever recorded on Earth was at Vostok: -89.2°C on 21st July 1983. The Dry Valleys of Antarctica are the most similar place on Earth to the desolate landscapes of the Moon and Mars.
Patagonian and British-Irish Ice Sheets
This website includes lots of information on other ice sheets, including the Teerwere Key Cabinet 24 Keys Slotted Key Cabinet Lock Box Wall M and the British-Irish Ice Sheets.
The Patagonian Ice Sheet reached its maximum extent around 27,000 years ago, and had formed a long, thin ice sheet along the Patagonian Andes. The dynamics of the ice sheet are closely related to the ocean currents and Southern Westerly Winds, and so the dynamics of this long, thin ice sheet can tell us about past climate.
The British-Irish Ice Sheet reached its maximum extent also at around 27,000 years ago. The ice sheet reached the continental shelf around its northern and western margin, leaving behind landforms like drumlins, moraines and ice-dammed lakes. It had a large marine margin, similar in some ways to Antarctica today.
The Greenland Ice Sheet
We have a new section on the JIAOAO 20 Pcs 9.0 Capacitive Pen,Tablet Stylus with Lanyard Univ, which introduces the ice sheet and investigates how it is changing today. This section includes information on Greenland’s ice tongues, supraglacial hydrology, and its dynamics and mass balance.
In 2020 we were awarded a “Certificate of Excellence for Geological Education” from the Geologists’ Association.
