Distinguishing between old and modern permafrost sources in the northeast Siberian land–shelf system with compound-specific <i>δ</i>²H analysis by J. E. Vonk, T. Tesi, T. Tesi, L. Bröder, L.

“…We tested this molecular <i>δ</i>²H tracer along with another source-distinguishing approach, dual-carbon (<i>δ</i>¹³C–Δ¹⁴C) isotope composition of bulk OC, for a surface sediment transect in the Laptev Sea. Results show that general offshore patterns along the shelf-slope transect are similar, but the source apportionment between the approaches vary, which may highlight the advantages of either. …”

Rise and fall of sea ice production in the Arctic Ocean’s ice factories by Cornish, S, Johnson, H, Mallett, R, Dörr, J, Kostov, Y, Richards, A

“…We focus on the Kara and Laptev seas-sometimes referred to as Arctic “ice factories” for their outsized role in ice production, and train the model on internal variability across the Community Earth System Model’s Large Ensemble (CESM-LE). …”

Two distinct declining trend of autumn Arctic sea ice concentration before and after 2002 by Yijiao Li, Zhina Jiang, Yao Yao, Minghu Ding, Lei Zhang

“…In comparison, a tendency towards a stronger Ural anticyclone combined with positive phase of the North Atlantic Oscillation pattern significantly promotes the increase of downward longwave radiation over Barents-Kara-Laptev Seas during 2002–2021. Our results set new insights into the Arctic sea ice variability and deepen our understanding of the climate change.…”

Recent autumn sea ice loss in the eastern Arctic enhanced by summer Asian-Pacific Oscillation by Botao Zhou, Ziyi Song, Zhicong Yin, Xinping Xu, Bo Sun, Pangchi Hsu, Haishan Chen

“…This warming persists to autumn and in turn triggers strong anticyclonic anomalies over the Barents-Kara-Laptev Seas and weak lower-tropospheric cyclonic anomalies over the East Siberian Sea, enhancing moisture transport into the eastern Arctic. …”
