What historical landfast ice observations tell us about projected ice conditions in Arctic archipelagoes and marginal seas under anthropogenic forcing by F. Laliberté, S. E. L. Howell, J.-F. Lemieux, F. Dupont, J. Lei

“…It is concluded that in the current generation of climate models, projections of winter sea ice conditions in the Canadian Arctic Archipelago and the Laptev Sea are overly sensitive to the representation of landfast ice conditions and that ongoing development in landfast ice parameterization will likely better constrain these projections.…”

Assessment of the Spatial Structure of Black Carbon Concentrations in the Near-Surface Arctic Atmosphere by Ekaterina S. Nagovitsyna, Vassily A. Poddubny, Alexander A. Karasev, Dmitry M. Kabanov, Olga R. Sidorova, Alexander S. Maslovsky

“…The simulation in the summertime demonstrates that areas of increased black carbon concentrations were observed over Northern Europe and, in 2019, also over the Laptev Sea basin. The obtained spatial distribution of mass concentrations of black carbon qualitatively agreed with the same data derived from the second Modern-Era Retrospective analysis for Research and Applications (MERRA-2) but showed quantitative differences. …”

A new interpretation of the inscriptions on the handles of signature knives found on the shores of Sims Bay by Avdeev A.G., Okladnikova Ye.A., Svoiskii U.M., Romanenko E.V.

“…The article reports on a new interpretation of the inscriptions on two personalized knives found on the coast of Sims Bay in the Laptev Sea. This interpretation differs from the readings published previously by paleographers and source-study experts due to the fact that it has been possible to devise correct transcription of these inscriptions with the aid of the method of non-contact 3D modeling of epigraphic records developed by the RSSDA Laboratory and used in the Code of Russian Inscriptions (CIR). …”

Heavy mineral assemblages of the De Long Trough and southern Lomonosov Ridge glacigenic deposits: implications for the East Siberian Ice Sheet extent by R. Alatarvas, M. O'Regan, K. Strand

“…The presence of glacial sediments and the recovered glacial–tectonic features on the East Siberian continental shelf and slope, along with the results from this heavy mineral analysis, imply that glacial ice not only grew out of the East Siberian shelf but also from the De Long Islands, and that there was also ice rafting related sediment transportation to the southern LR from westerly sources, such as the Laptev Sea.</p>…”

Estimation of the permafrost stability on the East Arctic shelf under the extreme climate warming scenario for the XXI century by V. V. Malakhova, E. N. Golubeva

“…However, our results show that even the extreme warming is not sufficient to destabilize the submarine permafrost on the shelf of both, the Laptev Sea and the East Siberian Sea. By the end of the 21st century, upper boundary of the permafrost deepens by value from 1 to 11 m only due to the thermal effects, and by 5–10 m in addition if we take into account the salinity of sediments. …”
