Algal pigments in Hornsund (Svalbard) sediments as biomarkers of Arctic productivity and environmental conditions

Polish Polar Research, 2017
Pigments (chloropigments-a and carotenoids) in sediments and macroalgae samples, collected in Hornsund, in July 2015 and July 2016, were analysed (HPLC) in this work.

GNSS sites at Hornsund reveal increase of land uplift rate due to recent acceleration of deglaciation at Svalbard

Reports on Geodesy and Geoinformatics
This paper discusses recent and up-to-date uplift rates at Polish Polar Station at Hornsund (SW Svalbard). Twenty years of continuous Global Navigation Satellite Systems (GNSS) measurements was used to infer contemporary vertical crust deformation due to

Automating long-term glacier dynamics monitoring using single-station seismological observations and fuzzy logic classification: a case study from Spitsbergen

Journal of Glaciology, 2017
Retreating glaciers are a consequence of a warming climate. Thus, numerous monitoring campaigns are being carried out to increase understanding of this on-going process.

Extent, duration and timing of the sea ice cover in Hornsund, Svalbard, from 2014–2023 [PDF]

The Cryosphere
The Sentinel-1A/B synthetic aperture radar (SAR) imagery archive between 14 October 2014 and 29 June 2023 was used in combination with a segmentation algorithm to create a series of binary ice/open-water maps of Hornsund fjord, Svalbard, at 50 m ...

Oceanographic monitoring in Hornsund fjord, Svalbard [PDF]

Earth System Science Data
Several climate-driven processes take place in the Arctic fjords. These include ice–ocean interactions, biodiversity and ocean circulation pattern changes, and coastal erosion phenomena.

Metal bioaccumulation and physiological responses of Arctic lichens under climate change and pollution

Ecological Indicators
Metal contamination and climate change, driven by global warming, are influencing the release and bioavailability of trace and heavy metals in the Arctic. Lichens, particularly Flavocetraria nivalis and Cladonia mitis, serve as effective bioindicators of

New insights on the depositional environment and dynamics of the lowermost Triassic in Svalbard: linking the Sørkapp-Hornsund High to western and central Spitsbergen

Sedimentologika
The area now known as the Barents Shelf region was strongly impacted by the End-Permian Mass Extinction and a fundamental reorganisation of source-to-sink systems along the northern margin of Pangaea. Here we integrate new sedimentological, ichnological,
