Pollen core
From Wikipedia, the free encyclopedia
A pollen core is a core sample of a medium containing sequences of pollen deposited over long periods of time. Analyses of the type and frequency of the pollen in each layer are used in studying historic climate change and are comparable to ice cores.
The cores are put through deposits where pollen is likely to have been trapped, in soil sediment or peat bogs where the anaerobic conditions have great preservative qualities.
The cores are then subject to pollen analysis by palynologists who are able to infer the proportions of major plant types from then concentrations of different pollen types found in the cores.
