Siwan Davies FLSW is a Welsh professor of Physical Geography in the department of science at Swansea University.

Together with a team of lecturing staff, technicians, PhD students and post doctoral researchers Davies is looking at rapid climatic changes.

By analyzing the microscopic ash particles in these matters Davies and her team can measure differences and similarities in changes that have occurred.

The findings within this excavation will include evidence of organic materials as well as air bubbles that will be an indication of greenhouse gases that could have been found in the atmosphere over 100,000 years ago.
