Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract We present a methodology for deriving the horizontal two‐dimensional distribution of low‐energy electron precipitation, specifically the possible lower bound of the differential energy flux of electron precipitation at 100 eV, from a 630‐nm auroral image obtained with a ground‐based all‐sky imager.

Journal of Geophysical Research: Oceans, Volume 131, Issue 1, January 2026.Abstract We present a new 27‐year record of landfast sea ice extent in northern Alaska and adjacent waters, which uses ice chart data to extend a previous analysis based on synthetic aperture radar (SAR) imagery. This new climatology provides updated information on the decline of landfast ice in a region of the Arctic that has seen extensive losses of ...

Oceanic Heat Transport Along the Norwegian Atlantic Slope Current and the Role of Eddies
Journal of Geophysical Research: Oceans, Volume 131, Issue 1, January 2026.Abstract The poleward warm Atlantic Water and returning cold water in the Nordic Seas play a crucial role in regulating the Northern Hemisphere climate. While previous studies have recognized the importance of mesoscale dynamics, a quantitative assessment of the role of mesoscale eddies in poleward heat transport is lacking.

Observation of O+ 4P-4D0 lines in proton aurora over Svalbard [PDF]
, 2004 Spectra of a proton aurora event show lines of O+ 4P-4D0 multiplet (4639–4696 Å) enhanced relative to the N2 +1N(0,2) compared to normal electron aurora. Conjugate satellite particle measurements are used as input to electron and proton transport models,

Environmental Controls on the Cycling of Fe and Mn in Patagonian Fjord Systems
Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 1, January 2026.Abstract Fjord sediments are important reservoirs and conduits of potentially bioavailable iron (Fe) and manganese (Mn). Both elements are critical to life, serving as key reactants in metabolic pathways, and play an important role in the reactivity and burial of organic carbon.

, 2022 Etter de tragiske ulykkene på Svalbard i 2015 og 2017 ble det satt i gang omfattende arbeider for å sikre lokalbefolkningen mot skred. Det er knyttet usikkerhet til om de lokale forholdene på Svalbard gir opphav til en endring i snøens mekaniske egenskaper, sammenlignet med blant annet Fastlands-Norge og Alpelandene.

Journal of Ecology, Volume 114, Issue 1, January 2026.Extreme rain‐on‐snow events forming basal‐ice can shape high Arctic plant communities as strongly as summer warming. Icing delays soil warming and early growth but compensatory responses follow, at the cost of reproduction. Summer warming offsets most icing impacts, enhancing growth and reversing phenological delays, though inflorescence remains ...

Radionuclides in arctic marine macroalgae from Kongsfjorden (Svalbard) [PDF]
, 2018 Seaweeds are known to be useful environmental bioindicators since they bioaccumulate radioisotopes at very low environmental concentrations. Levels of natural radionuclides in six ecologically relevant brown and red seaweed species from Arctic coasts ...
