The malacostracan fauna of two Arctic fjords (west Spitsbergen): the diversity and distribution patterns of its pelagic and benthic components

Oceanologia, 2017
This study examines the performance of pelagic and benthic Malacostraca in two glacial fjords of west Spitsbergen: Kongsfjorden, strongly influenced by warm Atlantic waters, and Hornsund which, because of the strong impact of the cold Sørkapp Current ...

Changes in the Coastal Wind Field and River Runoff Conditions Expose Kongsfjorden (Svalbard) to the Influence of Atlantic Water

Journal of Geophysical Research: Oceans, Volume 130, Issue 5, May 2025.
Abstract Kongsfjorden is located in West Spitsbergen, Svalbard archipelago. Its hydrography is influenced by the West Spitsbergen Current (WSC) transporting warm and saline Atlantic Water (AW) toward the Arctic basin. We assessed changes in fjord water properties over two decades (1999–2020) using summer hydrographic surveys performed by the Norwegian ...

On the Relationship Between Solar Wind High‐Speed Stream Waves and Geomagnetic Pc5 Activity From Mid to High Latitudes: A Case Study on January 5‐12 2008

Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract This study aims to investigate the possible influence of Alfvénic and compressive low‐frequency fluctuations in a solar wind corotating high‐speed stream on the geomagnetic activity from mid to high latitudes. We selected a stream in the declining phase of solar cycle 23, impinging on Earth's magnetosphere on 5–12 January 2008.

Ecosystem maturation follows the warming of the Arctic fjords

Oceanologia, 2017
Two fjords in West Spitsbergen (Hornsund 77°N and Kongsfjorden 79°N) differ with regard to their exposure towards increasingly warm Atlantic water inflow.

Magnetosheath Jet‐Triggered ULF Waves: Energy Deposition in the Ionosphere

Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract Magnetosheath jets, transient plasma structures of enhanced dynamic pressure, have been observed to trigger ultra‐low frequency (ULF) waves in the magnetosphere. These ULF waves contribute to energy transport in the magnetosphere‐ionosphere system. Therefore, there is a need to estimate the energy input into the ionosphere due to jet‐triggered

High Latitude Dust Transport Altitude Pattern Revealed from Deposition on Snow, Svalbard

Atmosphere, 2020
High Latitude Dust (HLD) deposition in the surface snow layer in two distant locations in Svalbard (Hornsund and Pyramiden) were collected during the June/July 2019 field campaign and examined in the laboratory.

Reduced‐Representation Sequencing Detects Trans‐Arctic Connectivity and Local Adaptation in Polar Cod (Boreogadus saida)

Molecular Ecology, Volume 34, Issue 7, April 2025.
ABSTRACT Information on connectivity and genetic structure of marine organisms remains sparse in frontier ecosystems such as the Arctic Ocean. Filling these knowledge gaps becomes increasingly urgent, as the Arctic is undergoing rapid physical, ecological and socio‐economic changes.

Crustal Heterogeneity Onshore Central Spitsbergen: Insights From New Gravity and Vintage Geophysical Data

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 1, January 2025.
Abstract Gravity data provide constraints on lateral subsurface density variations and thus provide crucial insights into the geological evolution of the region. Previously, gravity data from the Norwegian Arctic archipelago of Svalbard comprised an onshore regional gravity database with coarse station spacing of 2–20 km, offshore gravity profiles ...

Acoustical estimation of fish distribution and abundance in two Spitsbergen fjords

Oceanologia, 2017
Over recent decades, the Arctic region has been subjected to rapid climate change stemming from global warming. The advance of Atlantic waters to high latitudes is notable.
