Short summary
Short summary
Warm Atlantic Water loses heat as it flows eastwards along the continental slope north of Svalbard. Year-long mooring records show the current is most energetic in autumn and winter, when it is the strongest and warmest. Also conversion from mean and potential energy to eddy energy peak in autumn and winter. An ocean model shows energy conversion also on the deeper, offshore side, suggesting eddies transport heat towards the basin, contributing to along-slope heat loss.

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.

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.

Marine heatwaves—periods of extreme ocean temperatures—are increasing globally, posing a threat to marine ecosystems. One region where a high number of marine heatwave events per year has been observed is around Svalbard. This study characterises past marine heatwave events around Svalbard, including their extent in terms of both distance and depth. We identified eight events in western Svalbard that were largely driven by the movement of warmer water into the region by ocean currents.

We explored how virtual tools can help students prepare for and reflect on outdoor learning in the Arctic. Using surveys from university courses in Svalbard, we found that digital field visits helped students feel more confident, better understand the landscape, and learn more effectively. These tools do not replace real fieldwork but make it more accessible and inclusive. Our research shows how technology can support hands-on learning in remote environments.

ISLAS2020 set out to measure the stable water isotopic composition of Arctic moisture. By not only measuring at different sites around Ny-Ålesund, Svalbard, but also measuring at variable heights above surface level, we aim to characterize processes that produce or modify the isotopic composition. We also collect precipitation samples from sites that were typically downstream of Ny-Ålesund, so as to capture the isotopic composition during removal from the atmospheric water cycle.

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.

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.

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
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.
