Glaciers draining to the Hornsund basin (southern Spitsbergen, Svalbard) have experienced a significant retreat and mass volume loss over last decades, increasing input of freshwater into fjord. An increase in can influence fjord hydrology, hydrodynamics, sediment flux biota, especially changing climate. Here, we describe sources supply based on glaciological meteorological data from period 2006 2015. The average land bay is calculated as 2517 ± 82 Mt a−1, with main contributions glacier...
Cryoconite is a mixture of mineral and organic material covering glacial ice, playing important roles in biogeochemical cycles lowering the albedo glacier surface. Understanding differences structure cryoconite across globe can be recognizing past future changes supraglacial environments ice-organisms-minerals interactions. Despite worldwide distribution over century studies, basic characteristics cryoconite, including its forms geochemistry, remain poorly studied. The major purpose our...
Abstract Glacierised coasts undergo faster geomorphic processes than unglaciated ones. We have studied changes of the coastal area in southern Svalbard with glacier bridge between Torell Land and Sørkapp since beginning 20th century. The existence a continuous subglacial depression beneath Hornbreen–Hambergbreen system has been debated 1960s, inconclusive results. In this study we assess both topography bathymetry Hornsund Fjord Hambergbukta bay. This included ~40 km radar surveys over...
Abstract The mechanism of glacier recession and its climatic controls are complex processes that differ across the Arctic region. Here, we investigate factors influencing front variations Hansbreen, a terminated in Hornsund fjord (SW Svalbard). We apply remote sensing data to observe fluctuations between 1992 2015 compare them atmospheric oceanographic data, sea water depth at terminus surface velocity. Rate subglacial meltwater discharge approximated by seasonal positive degree‐day index...
In this study, we assess the accuracy and precision of digital elevation models (DEM) retrieved from aerial photographs taken in 2011 Very High Resolution satellite images (WorldView-2 Pléiades) period 2012–2017. Additionally, freely available Strip product ArcticDEM was verified. We use DEMs to characterize geometry changes over Hansbreen Hornbreen, two tidewater glaciers southern Spitsbergen, Svalbard. The satellite-based WorldView-2 Pléiades stereo pairs were processed using Rational...
Rapid Arctic warming results in increased winter rain frequencies, which may impact glacial systems. In this paper, we discuss climatology and precipitation form trends, followed by examining the influence of rainfall (Oct–May) on both mass balance dynamics Hansbreen (Svalbard). We used data from Hornsund meteorological station (01003 WMO), addition to original glaciological three measurement points Hansbreen. Precipitation phases were identified based records weather phenomena used—along...
Abstract The results from a hydrological monitoring program of Breelva basin (Spits− bergen, Svalbard) have been analysed to improve the understanding Werenskiöld Glacier system’s functioning in High Arctic. Hydrographs 44 km 2 river (27 which was covered by glacier) were for period 2007-2012. Sea− sonal discharge fluctuations linked glacier ablation and meteorological parameters, including atmospheric circulation types. A dichotomy found peaks generation during hydrologically active season,...
ABSTRACT Glacier naledi are extrusive ice masses that appear in front of glaciers as a consequence refreezing meltwater seepage during the accumulation season. These structures provide unique opportunity to understand subglacial drainage activity season; however, only few detailed studies have previously focused on their characteristics. Here, we investigated glacier-derived naled assemblages proglacial zone polythermal glacier Werenskioldbreen (27.4 km 2 ) SW Svalbard. We determined spatial...
We assessed the structure of microbial communities in subglacial drainage system Werenskioldbreen glacier, Svalbard, which consists three independent channels. Dome-shaped naled ice bodies that had been forming and releasing water glacial forefield during accumulations season were used to study microbiome. tested hypothesis properties transported by these channels are site-dependent influence bacterial diversity. therefore established phylogenetic using next generation sequencing (NGS) 16S...
Abstract. As the behavior of subglacial water plays a determining role in glacier dynamics, it requires particular attention, especially context climate warming, which is increasing ablation and generating greater amounts meltwater. On many glaciers, flowing from glacier's surface main source supply to drainage system. This system largely influenced by supraglacial system, collects meltwater precipitation rapidly delivers discrete points bed via moulins crevassed areas, called input areas...
The Arctic is one of the regions most affected by global climate change, and subjected to changes linked with a melting cryosphere increasing anthropopressure. Although antibiotic resistance problem, diversity spread antibiotic-resistant bacteria (ARB), genes (ARGs) integrons in are strongly understudied. Therefore, main aims this study (1) determination type frequency integron-integrase characterization incorporated gene cassettes genomes culturable (2) quantitative analysis class 1 human...
We present a detailed study on snow cover six different glaciers in southern Spitsbergen, Svalbard: Amundsenisen, Flatbreen, Hansbreen, Nannbreen, Storbreen and Werenskioldbreen. Fieldwork was carried out April–May 2013, at the end of accumulation season, to determine large-scale spatial distribution patterns surrounding Hornsund Fjord. Snow depth measured using an 800 MHz ground-penetrating radar (GPR). In addition, structure snowpack determined by digging pits collecting cores from glacier...
Environment of the Atlantic sector Arctic, where Svalbard ice masses lie, is highly vulnerable to climate changes. Mass balance a few selected glaciers are well known from field measurements, however it's also important calculate changes in glacier volume archived data and remote sensing methods for with no direct measurements. Rapid topography cause need eliminate uncertainties re-analyse mass calculations. In this study, based on digital elevation models photogrammetric photos satellite...

Abstract. Monitoring changes in glacial dynamics is essential for understanding the environmental response to accelerated climate warming Arctic. However, geodetic surveys polar regions continue present considerable challenges because of harsh conditions and night. This study records a 14-year-long time series (2006–2019) global navigation satellite system (GNSS) positions 16 ablation stakes distributed across Hansbreen, tidewater glacier southern Svalbard. The measurements were conducted...
Changes in glacier zones (e.g., firn, superimposed ice, ice) are good indicators of response to climate change. There few studies zone detection by SAR that focused on more than one ice body and validated terrestrial data. This study is unique terms the dataset collected—four C- L-band quad-pol satellite images, Ground Penetrating Radar data, shallow cores—and number land bodies analyzed, namely, three tidewater glaciers Svalbard cap Iceland. The main aim assess how well popular methods...
