The impact of stressors on cognition during a survival exercise in polar waters—results of an experiment in northern Norway
As sea ice diminishes with global warming, new opportunities for commercial shipping, tourism and fishing arise in the polar regions in the winter. With this comes the risk of accidents. Long distances and extreme environmental conditions compound the challenges of search and rescue operations in…

First breeding events of the pectoral sandpiper (Calidris melanotos) in north-east Greenland: a harbinger of breeding range expansion?
Tundra ecosystems are increasingly affected by the warming associated with climate change and the resulting poleward shift of animal and plant populations. The breeding ranges of some migratory waders nesting in the Arctic already appear to be shifting or expanding in response to the rising…

Small catchments: remote sensing approach for environmental research in the High Arctic
This study examines the morphometric characteristics and environmental changes in 143 small catchments within Wedel Jarlsberg Land, southern Svalbard, focusing on the influence of topography on glacier retreat, lake evolution, and vegetation dynamics. The catchments analysed varied in size, with…

Polar bear predation on barrier island bird colonies in Arctic Alaska increases with sea-ice decline
Anthropogenic carbon emissions are warming the Arctic, disrupting ecosystems, and changing the behaviour and interactions of their component species. As summer sea ice diminishes, polar bears (Ursus maritimus) are losing access to traditional seal prey and are increasingly forced onto land, where…

Documenting an isolated and high-priority Arctic cultural heritage site: case study from Kapp Pettersen, Svenskøya, Svalbard
With a warming climate, changing weather patterns and increased erosion from various permafrost- and marine-related processes, the cultural heritage (CH) sites in Svalbard are increasingly vulnerable to destruction. Documentation of CH sites in the Arctic can be very difficult on account of the…

An Adélie penguin (Pygoscelis adeliae) 200 km from the sea
This brief note reports an observation of an Adélie penguin (Pygoscelis adeliae) 200 km from the open sea, at Troll Research Station, in Dronning Maud Land, Antarctica, on the morning of 5 January 2026. The bird, which appeared to be in good condition, was not interfered with and was last seen…

Actor participation in the Arctic Council, 1998–2025: a new data set
The Arctic Council, once the primary forum for Arctic governance, has been facing significant disruptions since 2022, raising questions about the future direction of regional cooperation. Stored at the Arctic Data Center in the US, the ArcticPart data set covers over 25 years of participation in…

Comparative metagenomics of two shallow marine microbial communities in western Greenland
Metagenomic profiles of marine microbial communities from Greenlandic coastal waters remain scarce, despite the central role played by this region in discussions of global climate change. This study characterizes the taxonomic and functional structure of two near-shore shallow marine fjord mouth…

Weathering above the tides: how iceberg-roll-generated waves shape Arctic rocky shores
A significant limitation of the current understanding of cold coast evolution is the paucity of field observations on the development of rocky coasts in glaciated parts of the Arctic. To address this gap, we present a pilot study that utilizes a Schmidt hammer to investigate variations in rock…

A thermophilic hormone-sensitive lipase family esterase Est1404 identified from an Antarctic bacterium Pseudomonas sp. E2-15
Esterases are a group of enzymes with a diverse range of uses in industry. We identified a novel hormone-sensitive lipase (HSL) in the esterase family, Est1404, through cloning and expression from the Antarctic bacterium Pseudomonas sp. E2–15, from soil collected on King George Island…

Environmental management and stewardship practices in Antarctic science and tourism: do they align with environmental concerns?
In the Antarctic Peninsula, tourism and science operations are interconnected and overlap spatially and temporally, sharing practices aimed at reducing and mitigating the human footprint. Guided by the concepts of environmental management and environmental stewardship, we examined how these…

Arctic shipping 2013–2022: the traffic has grown, with big variation between regions, seasons and ship types
This article analyses decadal changes in Arctic ship traffic from 2013 to 2022, using data from the Arctic Ship Traffic Data system (ASTD). Shipping in waters affected by sea ice has grown, but how much depends on geographical definitions. The Polar Code area had an average annual growth of 8.7%…

Quantifying floridean starch storage patterns in Arctic rhodoliths: blue carbon implications
Rhodoliths composed of crustose coralline algae (CCA) are marine calcifiers of global significance. Here, we investigate how floridean starch storage patterns of Arctic rhodoliths from Svalbard are affected by environmental conditions. Quantifying the amount of starch in photomosaic scans of…

The muskox (Ovibos moschatus) in Sweden: update on a small wild population with an uncertain fate
Once widespread across the Holarctic region, the iconic and pre-historic muskox (Ovibos moschatus) has seen a significant range reduction, with endemic populations now restricted to North America and scattered populations introduced throughout Eurasia. In 1971, five individuals from the introduced…

Larsen’s cairn: the birth of a new historical site in Antarctica
This article describes the history of Larsen’s cairn, one of the oldest historical sites in Antarctica, and explains how it became one of the most recently declared Historical Site and Monuments (HSMs) on the continent. Norwegian explorer and whaler Carl Anton Larsen constructed the cairn on…

Mesoscale atmospheric processes over an Arctic fjord as observed during a research aircraft campaign in winter
Unique research aircraft observations were conducted within an Arctic fjord in Svalbard during three days in March 2013. Wijdefjorden is 110 km long, 5–15 km wide and has a north–south axis. Two-thirds of the fjord were covered by land-fast sea ice, but the northern part of the fjord was open. On…

Svalbard Rock Vault: towards safeguarding geological cores and borehole data
Continuous sedimentary drill cores provide crucial data for deciphering past climate variations and characterizing the subsurface for the energy industry (e.g., coal, petroleum, CO2 storage, geothermal energy). The Norwegian High-Arctic archipelago of Svalbard offers a diverse geological record…

Representation of Dense Shelf Water formation by global oceanic reanalyses
This study evaluates the representation of Dense Shelf Water (DSW) formation in the Southern Ocean by two global oceanic reanalyses: GLORYS2v4 and ORAS5. We found that GLORYS2v4 generally represents larger areas and more consistent temporal patterns of DSW compared to ORAS5. This latter reanalysis…

On ice but not broken: Norwegian–Russian relations in polar science since 24 February 2022
Western countries responded to the full-scale Russian attack on Ukraine on 24 February 2022 by imposing strong sanctions to isolate Russia. Norway has adhered to this policy, with exceptions for cooperation on border control, search and rescue, and fisheries research and management in the Barents…

Echo character mapping and depositional processes on the western Svalbard continental margin
An echo character mapping study of the western Svalbard continental margin, based on ca. 3980 km of archived sub-bottom profile data, is presented. Four distinct echo character types are recognized. Type I is found on the continental slope and in the fjords as thin, irregularly parallel, sub-bottom…
