Atlantic water (AW) is a key driver of change in the Barents Sea. We studied an emerging pathway through the Svalbard Archipelago that allows AW to enter the Barents Sea. We found that the Atlantic sector near the study site has warmed over the past 2 decades; that Atlantic-origin waters intermittently enter the Barents Sea through the aforementioned pathway; and that heat transport is driven by tides, wind events, and variations in the upstream current system.

Marine heatwaves occurrence is increasing, especially in northern oceans. In summer 2025, western/central Norway had the most intense event on record, with sea temperatures up to 22 °C. This event was shallow and developed quickly. It was mainly driven by unusual weather: strong solar radiation, weak winds, warm air, and persistent high pressure over Scandinavia. The occurrence of these rapid-forming events has important implications for predictability and adaptation.

This paper describes
Norkyst, the operational coastal ocean forecasting system for mainland Norway, which is now in version 3. The system produces five day forecasts of ocean currents, temperature, salinity, and sea surface height every day, and we also maintain an archive of historical data going back to 2012. We show that the outputs of Norkyst have sufficient quality so that it's intended use as a free public service supporting scientists, ocean managers, and industry is justified.

We used ocean gliders to measure separate circulation branches of warm Atlantic water flowing into the Arctic through a key passage west of Svalbard. Over three years, gliders revealed that two main current branches together carry about five million m3 s-1 northward, with large variations linked to wind patterns. These currents influence Arctic ice and climate. Our study shows gliders can capture changes missed by traditional methods, and year-round missions are needed for a complete picture.

Short summary
Thirty years of in situ hydrographic measurements combined with satellite observations reveal that Atlantic Water flowing northward along Norway is cooling less than before. We find that reduced surface heat loss and faster advection are likely drivers, though their relative effect varies over time. These changes result in more ocean heat reaching the Arctic, with likely impacts on climate, sea ice, and marine ecosystems.

The Lofoten Vortex is an unusual feature in the ocean: a permanent eddy which does not dissipate as most eddies do. We have long thought that other eddies must merge into the vortex in order to maintain its heat content and energetics, but such mergers are very difficult to observe due to their transient, unpredictable nature. For the first time, we have observed a merger using an ocean glider and high-resolution satellite data and can document how the merger affects the properties of the vortex.

West of Svalbard, warm Atlantic Water frequently deviates from the West Spitsbergen Current onto shallow shelf areas, with significant implications for the regional climate system. The intrusions can be triggered by different processes, but their depths ultimately depend on the density difference between the intruding water and the ambient shelf water. These findings are an important step toward a better understanding of how warm Atlantic Water eventually reaches the fjords of Svalbard.

In the northwestern Barents Sea, we study the Barents Sea Polar Front formed by Atlantic Water meeting Polar Water. Analyses of ship and glider data from October 2020 to February 2021 show a density front with warm, salty water intruding under cold, fresh water. Short-term variability is linked to tidal currents and mesoscale eddies, influencing front position, density slopes and water mass transformation. Despite seasonal changes in the upper layers, the front remains stable below 100 m depth.

Our research introduces a tool for dynamically mapping the Arctic Ocean using data from the MOSAiC experiment. Incorporating extensive data into a model clarifies the ocean's structure and movement. Our findings on temperature, salinity, and currents reveal how water layers mix and identify areas of intense water movement. This enhances understanding of Arctic Ocean dynamics and supports climate impact studies. Our work is vital for comprehending this key region in global climate science.

The Isfjorden Weather Information Network (IWIN) provides continuous meteorological near-surface observations from Isfjorden in Svalbard. The network combines permanent automatic weather stations on lighthouses along the coast line with mobile stations on board small tourist cruise ships regularly trafficking the fjord during spring to autumn. All data are available online in near-real time. Besides their scientific value, IWIN data crucially enhance the safety of field activities in the region.

Sea ice models are often implemented for very large domains beyond the regions of sea ice formation, such as the whole Arctic or all of Antarctica. In this study, we implement changes in the Los Alamos Sea Ice Model, allowing it to be implemented for relatively small regions within the Arctic or Antarctica and yet considering the presence and influence of sea ice outside the represented areas. Such regional implementations are important when spatially detailed results are required.

A turbulence instrument was installed on a light autonomous underwater vehicle (AUV) and deployed in the Barents Sea in February 2021. We present the data quality and discuss limitations when measuring turbulence from the AUV. AUV vibrations contaminate the turbulence measurements, yet the measurements were sufficiently cleaned when the AUV operated in turbulent environments. In quiescent environments the noise from the AUV became relatively large, making the turbulence measurements unreliable.

Here, we describe a strait that has narrow and shallow sills in both ends and is close to an amphidromic region. This generates tidally driven flows into and out of the strait, but with very different exchange rates across the entrances in both ends so that it behaves like a mixture between a strait and a fjord. Using a numerical model, we find a fortnightly signal in the net transport through the strait, generated by long-period tides. Our findings are verified by observations.

Short summary
Warm Atlantic Water flowing eastward north of Svalbard loses heat faster than can be explained by cooling to the atmosphere and mixing alone. Using year-long mooring observations and an ocean model, we found that mesoscale variability and energy transfer into eddies are largest in autumn and winter, when the boundary current is also at its strongest and warmest. This mesoscale activity enhances lateral heat exchange and likely contributes to the observed cooling of Atlantic Water along its path.
