Species diversity of macroalgae in Grønfjorden, Spitsbergen, Svalbard

Polar Research, 2021
Climate changes in the North Atlantic and Arctic affect the macrophytobenthos along with other components of the ecosystem, resulting in an increase of species diversity and biomass in western Spitsbergen, as has been reported.

Bed‐scale quantitative discrimination of hyperpycnites from intrabasinal turbidites—Results from a channelised slope system in the Upper Carboniferous Westward Ho! Formation, United Kingdom

Sedimentology, Volume 73, Issue 5, Page 1750-1798, August 2026.
ABSTRACT Features considered indicative of hyperpycnites and intrabasinal turbidites overlap. Outcrop study presented here suggests that the Westward Ho! Formation forms an 800 m high deepwater‐slope system dominated by hyperpycnites. Taking this unit, and other successions where hyperpycnites have been described, as having been deposited solely from ...

The Impact of Subglacial Drainage System Evolution and Glacier Lake Outburst on Arctic Fjord Macronutrient Dynamics

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Global warming is amplified in the Arctic, accelerating glacier melt and freshwater runoff. At tidewater glaciers, runoff typically enters fjords at depth and generates buoyancy‐driven circulation that enhances glacier‐ocean exchanges of energy and matter, influencing macronutrient delivery and marine primary production.

Model Biases and Sensitivities in Simulating Extreme Sea Ice Loss Around Svalbard During the January 2022 Record Cyclone

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract The record‐breaking Arctic cyclone of January 2022 caused an unprecedented sea ice loss in the Barents Sea near Svalbard, which was severely underestimated by both the ECMWF operational forecast and the CESM1 global climate model. To investigate this discrepancy and further explore the mechanisms that led to sea ice loss, we utilize a regional

Minimal Perturbation of the Global Mercury Cycle by the Paraná–Etendeka Large Igneous Province (PE–LIP) During the Onset of the Valanginian Weissert Event

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract The Valanginian positive carbon isotope excursion (Weissert Event, ca. 135 million years ago) documents a major global carbon cycle and climate perturbation. Radioisotopic dating suggests that this event was broadly contemporaneous with an interval of profoundly enhanced volcanic activity during the emplacement of the Paraná–Etendeka Large ...

Post-pandemic tourism in Longyearbyen [PDF]

Polish Polar Research
Tourism in Spitsbergen has become the largest employer and most rapidly growing sector, taking over from coal mining. Longyearbyen is a small urban center but it is the central hub where most tourism passes through.

Addressing Uncertainties in Climate–Ecosystem Feedbacks in the Arctic: Ten Priority Research Questions for Integrated Observation and Modeling

Ecological Research, Volume 41, Issue 4, July 2026.
Uncertainties exist in the biosphere–climate feedbacks in the Arctic. Remote and ground measurements play complementary roles in detecting possible changes. A critical next step is identification of key drivers of the global changes for future projections. ABSTRACT Positive biosphere–climate feedbacks are likely to amplify the Arctic warming, yet major

Structure and evolution of the Bellsund Graben between Forlandsundet and Bellsund (Spitsbergen) based on marine seismic data [PDF]

, 2009
Seismic interpretation of multi-channel seismic data acquired along the western shelf of Spitsbergen allowed identification of the main geological features of the area, including the Hornsund Fault Zone, and the Forlandsundet and Bellsund grabens.

Analysis of the paraglacial landscape in the Ny-Ålesund area and Blomstrandøya (Kongsfjorden, Svalbard, Norway)

Journal of Maps, 2020
Ice cover changes have affected the Svalbard Islands during the Quaternary and conditioned a complex paraglacial landscape. In these remote and poorly vegetated arctic areas, the integration of field investigations and analysis of aerial images and DTMs ...

Taxonomic and functional diversity of benthic foraminifera as a promising proxy for tidewater glacier retreat

Boreas, Volume 55, Issue 3, Page 885-902, July 2026.
Ice sheets and glaciers globally are losing mass at increasing rates, with the strongest changes occurring at tidewater glaciers. These are rapidly retreating and often transitioning to land‐terminating with implications for sea level change and ecosystem functioning.
