This dataset includes two raw Illumina NextSeq 500 libraries (paired-end sequenced) and the associated OBITools PCR-tag lookup tables required for demultiplexing.,DNA metabarcoding of ancient lake sediments collected from Andøya, Norway. The chloroplast trnL (UAA) intron, or p6-loop, was amplified for the sediment extracts.,Andøya on the NW coast of Norway is a key site for understanding the Last Glacial Maximum (LGM) in northern Europe. Controversy has arisen concerning the local conditions, especially about the timing and extent of local glacial cover, maximum July temperatures and whether pine and/or spruce could have grown there. We reviewed all existing data and add newly analysed ancient sedimentary DNA, pollen, macrofossils, geochemistry and stable isotopes from three lake sediment cores from Øvre Æråsvatnet. A total of 23 new dates and age-depth modelling suggests the lake has been ice-free since GI2 (
