Lake sediment stratigraphy, radiocarbon chronology, geochemically characterized tephra and mineralogy reveal ice-free conditions on coastal Spitsbergen during Last Glacial

This dataset characterizes the first pre-Holocene lake sediments from Arctic Svalbard. Three bryophyte-derived 14C ages reveal that the targeted sequences was deposited between 30 and 20 ka BP - indicating ice-free and vegetated conditions during the Last Glacial Maximum. We also fingerprint a new v...
