Geoconservation – principles into practice

Zoom Talk

given by Dr Colin Prosser (Principle Specialist in Geoconservation, Natural England). Rearranged from October 2020. Abstract: The UK is extremely geodiverse with many geological features and sites of international, national and local importance for research, education, tourism and recreation. However, we are a small country with a large population and our geoheritage is subject to […]

Geoscience, and the World After Oil

Zoom Talk

The last British Ice Sheet

Zoom Talk

given by Dr Bethan Davies (Royal Holloway, University of London) Abstract: Understanding how the last British-Irish Ice Sheet behaved in response to external climatic forcing may be used as an analogue for how the Antarctic Ice Sheet may behave in the future. We can use these empirical datasets to calibrate numerical simulations and better understand […]

Several hypotheses have been proposed to explain this size decrease among […]
