The mean thickness calculated 171 m volume estimated to be 9.6 (±0.1) km 3 . main feature bedrock vast depression that...

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...

Despite recent great interest in glacier ecosystems the continental Antarctic, little is known about their maritime counterparts. Our study presents descriptive data on cryoconite sediments and holes Ecology Glacier (King George Island) to accomplish three main objectives: (a) identify eukaryotic (algae, invertebrates) prokaryotic (cyanobacteria) components of microbial communities; (b) provide a "baseline" community composition, organic matter artificial contamination; (c) key abiotic...

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...

Snow distribution patterns on Svalbard glaciers derived from radio-echo soundings The spatial of snow thickness is driven by a set climatological, meteorological, topographical and orographic conditions. This work presents results accumulation studies carried out 2006 to 2009 different types: valley glacier, ice plateau cap. In order determine depth, shallow radio echo-sounding method was used. Based the results, following have been distinguished: precipitation pattern,...

Abstract We present the variability of thermal state and thickness permafrost active layer at raised marine beaches in Svalbard. The investigations were carried out using direct probing, thaw tube, ground temperature radar soundings Holocene strand plains 10-20 m a.s.l. Fuglebergsletta (SW Spitsbergen) shore Kinnvika Bay (Nordaustlandet). Their results compared to those obtained other coastal sites measurements conducted 2009 on August, recognized as standard month for maximum thawing during...

Abstract This paper presents a detailed study of melting processes conducted on Hansbreen – tidewater glacier terminating in the Hornsund fjord, Spitsbergen. The fieldwork was carried out from April to July 2010. included observations meltwater distribution within snow profiles different locations and determination its penetration time ice surface. In addition, variability temperature heat transfer cover were measured. main objective concerns impact diversity physical characteristics...

This paper provides an overview of the results research on changes in ground temperature down to 50 cm depth, Kaffiøyra Plain, Spitsbergen summer seasons.To achieve this, measurement data were analysed from three different ecotopes (CALM Site P2A, P2B and P2C) -a beach, a moraine tundra -collected during 22 polar expeditions between 1975 2014.To ensure comparability, sets for common period 21 July 31 August (referred as "summer season" further text) analysed.The greatest influence across...

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...

The authors propose a model of glacial mass balance based on correlations with meteorological observations and data from climate re-analysis. minimum input required include the following: average monthly temperature glacier in its vicinity during summertime for reference time period, air temperature, precipitation total at nearest weather station or This was used to hindcast components Werenskioldbreen (southern Svalbard) over period 1912–2005. specific then estimate change thickness snout...

Meteorological and biometeorological conditions in the Hornsund area (Spitsbergen) during warm season seasons (June-September) of 1979-2008 are described for area, Spitsbergen. The measurements were taken at four sites: Hornsund, Hans Glacier (at its equilibrium line firn section) summit Fugleberget. variation meteorological was analysed relation to altitude, distance from sea ground type. In seasons, air temperature 2.2 °C higher on average than (central by 2.8 (firn wind speed recorded...

This article presents the variations in air temperature and humidity region of Hornsund fjord for period from 1 July 2014 to 30 June 2015. Based on measurements at 11 sites, it was established that significant topoclimatic differences were dependent height above sea level, substrate type, distance sea, exposition, atmospheric circulation ice conditions.

Abstract The frequency, strength and seasonal variations of surface-based temperature inversions (SBTIs) in Upper Silesia (Southern Poland) were examined using data from January 2001 to September 2020. Based on the air temperatures recorded at meteorological station Institute Earth Sciences Sosnowiec (263 m a.s.l.) heights 2 88 above ground, vertical gradient 100-m layer ( γ Sos 100 m) was determined.

Abstract. The warming of the Arctic climate is well documented, but mechanisms amplification are still not fully understood. Thus, monitoring glaciological and meteorological variables environmental response to accelerated must be continued developed in Svalbard. Long-term observations carried out situ on glaciers conjunction with rare significantly expand our knowledge about processes polar environment. This study presents unique data collected 2009–2020 southern Spitsbergen...

In this paper, a method for estimating snow pressure reflection coefficient based on non-contact ultrasound examination is described. A constant frequency and air-coupled pulses were used in study, which incorporates parametric reflected energy estimation. The experimental part was carried out situ the Antarctic, where parameters measured along with meteorological data. proposed represents promising alternative snow-water equivalent, since it uses approach, does not require measurements of...

Obecnie obserwowane są znaczne zmiany klimatu w Arktyce i Antarktyce. Wzrost średniej temperatury powietrza latach 1979-2019 był trzykrotnie wyższy niż średnia globalna.
