The stable isotopic composition (δ18O, δD, d) of three Holocene‐age ice wedges at the Dmitrii Laptev Strait, Russia (Oyogos Yar coast, 72.7°N, 143.5°E) was studied at high resolution (100 to 200 samples each) in order to develop palaeoclimatic records. AMS 14C ages of organic matter in the ice prove the Late Holocene age of the studied horizontal ice‐wedge profiles and indicate syngenetic growth associated...
