Soil core for pollen research. Researchers measuring and marking a soil core taken from a field during research into the botanical history of the region. The soil core takes a long cylinder of soil,with the deeper parts being older. The core will be taken back to a laboratory where the pollen in various layers will be studied,allowing researchers to determine the changes in plant life in the region over the last few thousand years.
