Multiproxy late Holocene peat records from Ireland: towards a regional palaeoclimate curve
Two new peat-based climate records from Ireland covering the late Holocene are presented. The sequences are dated by a strong chronological framework formed by AMS radiocarbon dates and SCPs. Three proxy indicators (testate amoebae, macrofossils and humification) have been determined allowing the li...
