Article written by Alex Clark (Royal Holloway University of London) Fieldwork is all about making discoveries. It’s an opportunity to take what you have learned at your desk and see for yourself if it is true, or if there is more to be said. Usually, it is the latter. Though probably not at the top

This page was written by Dr Keir Nichols, who is using 14C exposure age dating to unravel the past behaviour of the West Antarctic Ice Sheet (WAIS). Given that the ice sheets in Antarctica and Greenland contain enough water to raise global sea level by about 65 metres, it is important to understand how ice

Cosmic rays are high energy particles that flow into our solar system from outer space. They are essential for the production
This section of the website introduces some of the very many different ways in which we can date glacial environments. These techniques have evolved through time, and different techniques are applied in different circumstances. For example, where organics are available, sediments can be dating using radiocarbon dating. This may be applied in glacial environments by,
