Applying UAV-Based Remote Sensing Observation Products in High Arctic Catchments in SW Spitsbergen

Remote Sensing, 2023
In the age of remote sensing, particularly with new generation Uncrewed Aerial Vehicles (UAVs), there is a broad spectrum of applications, especially in remote and rapidly changing areas such as the Arctic.

Freshwater input to the Arctic fjord Hornsund (Svalbard)

Polar Research, 2019
Glaciers draining to the Hornsund basin (southern Spitsbergen, Svalbard) have experienced a significant retreat and mass volume loss over the last decades, increasing the input of freshwater into the fjord.

Subsurface Investigations of Cryo‐Hydrogeological Features in a High Arctic Catchment Under Transition

Permafrost and Periglacial Processes, Volume 37, Issue 2, Page 267-283, April/June 2026.
ABSTRACT In this study, the internal structure and seasonal variations of cryo‐hydrogeological features were investigated in the Fuglebekken catchment, located near the Polish Polar Station Hornsund in Svalbard. Over a few years, rising air temperatures and intensified water circulation have significantly altered the distribution, extent, and state of ...

The sublittoral macroflora of Hornsund [PDF]

Polar Research, 2012
Combined hydroacoustic, video and direct examination by scuba-diving of the underwater meadows of Hornsund, a flagship biodiversity site in Svalbard, revealed 17 species of macroalgae with a biomass, dominated by Laminariales, of as much as 3 kg m−

Moss diatoms show regional structuring, high potential endemism, and an inverse latitudinal diversity gradient in the Arctic

Ecography, Volume 2026, Issue 3, March 2026.
Microorganisms perform essential functions in Arctic terrestrial ecosystems. Yet, their ecology and biogeography are poorly understood, despite being necessary to predict microbial responses to future climate change. Here, we provide the first large‐scale floristic and biogeographic study of the moss diatom flora in the tundra regions of the North ...

The Evolution of a Polar Cap Patch Into a Blob in the Nightside Ionosphere: Direct Observations of Multiple Blob Formation Mechanisms Acting Simultaneously on the Same Plasma

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract A polar cap patch was observed to exit the polar cap to become a blob as it entered the auroral oval on the nightside of the Earth under moderately quiet geomagnetic conditions (Kp = 3−). Auroral particle precipitation led to an increase in the electron density of the blob.

Crustal Heterogeneity Onshore Spitsbergen: Data Integration and Forward Modeling of Potential Field Data

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract The Svalbard archipelago is well‐known for its outcropping geology, but its subsurface geometry and physical properties are less well constrained. To address this knowledge gap, a multidisciplinary approach has been applied to integrate potential field data with seismic reflection profiles, exploration boreholes and geology.

Interannual variability in hydrography and water mass distribution in Hornsund, an Arctic fjord in Svalbard

Polar Research, 2018
Progressing warming in the Arctic and increased extreme weather events can significantly influence the hydrography of Svalbard fjords, leading to changes towards more Atlantic-type waters in the fjords.

Modelling of the thermal regime of permafrost during 1990–2014 in Hornsund, Svalbard

Polish Polar Research, 2016
The thermal state of permafrost is a crucial indicator of environmental changes occurring in the Arctic. The monitoring of ground temperatures in Svalbard has been carried out in instrumented boreholes, although only few are deeper than 10 m and none are

Investigation of Icelandic Dust Presence in the Aerosols Collected at Hornsund (Svalbard, Norwegian Arctic) in Spring 2019

Atmosphere
An integrated morphological and chemical analysis of Arctic aerosols was undertaken for Icelandic dust and Svalbard aerosols to be compared by scanning electron microscopy coupled with EDS microanalysis (SEM–EDS) via imaging and chemical analysis ...
