“…Indirectly dated MIS 2 wedge ice (28.4 Kyr b2k) on Bykovsky Peninsula (Laptev Sea) shows δ 18 O of −30.8 ± 0.6‰; well within the range of MIS 3 ice wedge isotopic compositions at this location (H. Meyer, Dereviagin, Siegert, & Hubberten, 2002). MIS 2 wedge‐ice, directly dated to 25.3 and 23.5 Kyr b2k, from Sobo‐Sise Island (Lena Delta) with mean δ 18 O of −28.8 ± 0.5‰ does not differ much from MIS 3 (δ 18 O from −31.4 ± 1.1 to −30.5 ± 0.8‰; Wetterich et al., 2020). Hitherto, it is not sufficiently resolved yet, whether this is due to a less cold LGM climate in the region or poor LGM representation in the studied ice wedge profiles.…”
