The authors analyzed plant macrofossils, peat humification and testate amoebae to reconstruct a proxy climate record spanning the last 7500 years of an ombrotrophic bog, Temple Hill Moss, in southeast Scotland.    From Wordnik.com.  [New Content on CO2 Science] Reference

Working with plant macrofossil, peat humification, and testate amoebae data, which they obtained from cores extracted from an ombrotrophic bog (Temple Hill Moss in southeast Scotland), the authors reconstructed a proxy climate record spanning the last 7500 years.    From Wordnik.com.  [New Content on CO2 Science] Reference
