Climate and atmospheric circulation changes over the past 1000 years reconstructed from oxygen isotopes in lake-sediment carbonate from Ireland

Unfortunately, neither of these cellulose-inferred lakewater d18O records extends to the present, which precludes direct linking with time series of modern lakewater d18O measurements

Sediment samples were washed in 10% HCl to eliminate biogenic and mineral carbonates, freeze-dried, and gently dry-sieved using a 500-mm mesh. The sieving step removes the larger organic fragments, which have a greater potential to be derived from in-washed terrestrial material, while concentrating the fine organic fraction, derived primarily from zooplankton faecal pellets that deliver aquatic organic matter directly to the sediments (Edwards 1993). The fine-grained fraction was then processed through additional steps to remove non-cellulose organic components and minerogenic matter, including solvent extraction, bleaching, alkaline hydrolysis, oxyhydroxide leaching, and sodium polytungstate density separation
