The Role of Light Absorbing Particles in Snow and Ice on Svalbard: A Focus on Dust Open
The Arctic is warming as much as four times the global rate, with warming particularly pronounced on Svalbard. This warming is leading to reductions in snow, glaciers and sea ice and a potential increase of local dust emissions. In additio…

Improving our Understanding of Melt-Affected Ice Cores Through In-Situ Percolation Tracer Experiments Open
Rising global temperatures and accelerated melting cause glaciers across the globe to shrink, thereby hampering our ability to reconstruct past climate from ice cores across the globe. In this context, melt-induced alterations of chemical …

Characteristics and quantification of small microplastics (<100 µm) in seasonal svalbard snow on glaciers and lands Open
Small microplastics (SMPs < 100 µm) can easily be transported over long distances far from their sources through the atmospheric pathways and reach even remote regions, including the Arctic. However, these sizes of MPs are mostly overlooke…

An agenda for the future of Arctic snow research: the view from Svalbard Open
The Arctic region is warming at over twice the mean rate of the Northern Hemisphere and nearly four times faster than the globe since 1979. The local rate of warming is even higher in the European archipelago of Svalbard. This warming is t…

Organic Compounds, Radiocarbon, Trace Elements and Atmospheric Transport Illuminating Sources of Elemental Carbon in a 300‐Year Svalbard Ice Core Open
Black carbon (BC) particles produced by incomplete combustion of biomass and fossil fuels warm the atmosphere and decrease the reflectivity of snow and ice, hastening their melt. Although the significance of BC in Arctic climate change is …

Snow cover monitoring in the Arctic (Svalbard) with RADARSAT Constellation Mission (RCM). Comparison with in-situ measurements and TerraSAR-X data Open
Arctic snow cover dynamics exhibit modification in terms of extent and duration due to recent changes in climate, i.e. increasing temperatures and changing precipitation patterns, i.e. winter rain-on-snow events (WROS). Remote sensing meth…
