Environmental controls of rapid terrestrial organic matter mobilization to the western Laptev Sea since the Last Deglaciation [PDF]

Climate of the Past
Arctic permafrost stores vast amounts of terrestrial organic matter (terrOM). Under warming climate conditions, Arctic permafrost thaws, releasing aged carbon and potentially impacting the modern carbon cycle.

Historical Increase in Autumn and Winter Cyclone‐Associated Precipitation Over the Arctic Ocean Driven Primarily by Enhanced Arctic Evaporation

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract What is the relative importance of variability in local evaporation versus moisture convergence from lower latitudes to changes in autumn/winter Arctic Ocean precipitation? Past research has offered sometimes contradictory answers. Here we offer some resolution to this question by addressing two research gaps.

Deglacial Permafrost Organic Carbon Delivery at the Northern Svalbard Continental Margin: Insights From Tetraether Lipids and Plant Biomarkers

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Degradation of Arctic permafrost due to global warming and sea level rise could trigger positive feedbacks, exacerbating climate change. However, uncertainties remain on how permafrost systems may respond because we lack a complete understanding of the permafrost‐climate feedback.

Long‐Term Trends and Variability in Arctic Mixed Layer Depth

Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract The Arctic surface mixed layer is an important moderator of the transfer of heat, salt, and momentum between the atmosphere and the warmer, more saline water that enter the Arctic Ocean from the North Pacific and North Atlantic oceans. However, prior observational studies of trends in mixed layer depth produce seemingly conflicting results due

Microfossil (Diatoms, Tintinnids, and Testate Amoebae) Assemblages in the Holocene Sediments of the Laptev Sea Shelf off the Yana River as a Proxy for Paleoenvironments

Quaternary
The paper presents the results of a microfossil study of Holocene sediments in the Yana River flow zone in the southeastern part of the Laptev Sea. A rich diatom flora (242 species and intraspecific taxa, of which 177 species are freshwater) was revealed;

Non‐native pink salmon Oncorhynchus gorbuscha carcasses benefit native benthic macroinvertebrates

Journal of Fish Biology, Volume 108, Issue 6, Page 1825-1837, June 2026.
Abstract The invasion of the North Atlantic by pink salmon Oncorhynchus gorbuscha has raised concerns regarding their impact on coastal rivers. Although the influence of marine‐derived nutrients from returning adult O. gorbuscha on rivers in their native range has received much attention, the ecological consequences of invasive O.

Episodic warming of near‐bottom waters under the Arctic sea ice on the central Laptev Sea shelf

Geophysical Research Letters, 2016
A multiyear mooring record (2007–2014) and satellite imagery highlight the strong temperature variability and unique hydrographic nature of the Laptev Sea.

Stages of sea ice development in the Laptev sea

Arctic and Antarctic Research, 2017
Variability of the stages of sea ice development in the Laptev Sea is assessed with 10-days periodicity for the autumn — winter period on a basis of AARI digital ice charts for 1997–2017. Difference in formation of the stages of ice development (ice thickness) was revealed between the drifting and fast ice, which is manifested in an earlier appearance ...
