Chironomid-based temperature reconstruction from Burgäschisee, Switzerland

<p>The data herein presents a new chironomid record and associated chironomid-based temperature reconstruction covering the time interval 18,000-14,000 cal. BP from the lacustrine sediments of a kettle hole lake Burgäschisee, Switzerland. Chironomid assemblages show ecological turnover beginning 1,300 years before the onset of the Oldest Dryas / <span>Bølling</span> transition at ca. 14,700 cal. BP and associated increases in chironomid-based temperature reconstructions. These data also include non-chironomid invertebrate remains, including Ceratopogonidae, Daphnia and Ephemeroptera as well as Characean oospores.</p>
