AntarcticGlaciers.org is a very useful and interesting website on the the science of Antarctic glaciology written by Dr Bethan Davies from Royal Holloway, University of London. Here is the introduction:

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 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. It’s the world’s fifth largest continent, and it is, on average, the highest and coldest continent. Antarctica also 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.

If you would like to find out more about this fascinating topic, do explore the AntarcticGlaciers.org website, which includes information about different types of glacier, ice shelves, and ice streams as well as the section on glaciers and climate. There is a lot of material that you'll enjoy browsing, and if you are taking A level Geography, this section helps you to find the relevant material for different parts of your course. You can also ask questions here.
