Abstract Growing season conditions are widely recognized as the main driver for tundra shrub radial growth, but effects of winter warming and snow remain an open question. Here, we present a more than 100 years long Betula nana ring‐width chronology from Disko Island in western Greenland that demonstrates highly significant positive growth response to both summer air temperatures during past century. The importance is especially pronounced periods 1910–1930 1990–2011 were dominated by...
Arctic ecosystems are important carbon sinks. Increasing temperatures in these regions might stimulate soil release. Evidence suggests that deciduous shrubs counteract losses because they positively respond to increasing temperature, but their role ecosystem budgets remains uncertain. Many studies dealing with large-scale tundra greening and sequestration relation temperature have usually based estimations on the aboveground components, very little is known about belowground growth. In this...
ABSTRACT In this article, the results of an investigation into air temperature conditions on Svalbard in period 1 September 2010 to 31 August 2011 are presented. For period, parallel measurements have been made as many 30 sites. On basis unique set data it was possible study, detail, spatial distribution different thermal characteristics [mean temperature, diurnal range (DTR), day‐to‐day variability, degree climate continentality, etc.] Svalbard. Such knowledge whole not previously available...
Significance Two defining features of climate change in the Arctic are rapid decline sea ice and “shrubification” tundra. While previous studies have inferred warming-related linkages between two, these been limited to a few locations. Our Pan-Arctic analysis shrub growth chronologies reveals two important insights. Tundra dynamics associated with throughout Arctic; however, while shrubs from most locations increased their growth, more than one-third showed evidence declining response...
Abstract Vegetation succession in front of five retreating glaciers was studied using phytosociological relevés (60) located at different distances between the Little Ice Age (LIA) moraines and present glacier fronts around Petunia Bay. Approximate dating stages based on a study changing position past approximately 100 years. The described corresponds to uni-directional, non-replacement model succession. All constituent species, except one, nearby old tundra have colonized forelands since...
Patchy global data on belowground litter decomposition dynamics limit our capacity to discern the drivers of carbon preservation and storage across inland coastal wetlands. We performed a global, multiyear study in over 180 wetlands 28 countries 8 macroclimates using standardized as measures "recalcitrant" (rooibos tea) "labile" (green organic matter (OM) decomposition. Freshwater tidal marshes had highest tea mass remaining, indicating greater potential for these ecosystems. Recalcitrant OM...
The aim of this article is to show geomorphological mapping remote Antarctic locations using images taken by a fixed-wing unmanned aerial vehicle (UAV) during the Beyond Visual Line Sight (BVLOS) operations. We mapped landform assemblages developed in forelands Ecology Glacier (EGF), Sphinx (SGF) and Baranowski (BGF) Specially Protected Area No. 128 (ASPA 128) on King George Island (South Shetland Islands) inferred about glacial dynamics. orthophoto digital elevation model allowed for...
Svalbard was long seen as a canary in the coalmine for climate change. Now this early warning system has suffered irreparable damage. warmed 2-6 times faster than rest of world, and we can expect further increase air temperature (by 4–7°C), precipitation 45–65%) more frequent heavy rainfall floods. Contrary to predictions from regional models, freshwater fluxes some glacierised catchments have steadily decreased over decade. Yet dominated watersheds, water discharge been increasing. To...
Quantitative measurements of aeolian activity at high latitudes are not currently carried out on a large scale, even though these processes important elements the geomorphic system polar regions, which particularly affected by climate change. This study presents results deposition rates measured and calculated for one central Spitsbergen postglacial valleys (Ebba Valley). The based seven summer season field campaigns (2012–2018), as well AMS 14C OSL dating niveo-aeolian sediments....
Paraglacial Modifications of Glacial Sediments Over Millennial to Decadal Time-Scales in the High Arctic (Billefjorden, Central Spitsbergen, Svalbard) The paper discuss morphologic expression and sedimentological record left after operation glacial episodes area Billefjorden, central period Late Pleistocene ice-sheet development last advance glaciers Little Ice Age (LIA) around beginning 20 th century. No evidence is found for other Holocene glacier advances. activity during several...
Paper described geomorphological characteristics of landform sets which occur on research areas investigated by Polish geomorphologists Spitsbergen.These area involve four along the western coast Spitsbergen, i.e. vicinities Kaffiøyra, Werenskioldbreen, Calyp sostranda, and Hornsund, as wel one located in central part vicinity Billefjord with special emphasis surroundings Petuniabkukta.Landforms are characterized different morphogenetic terms, mainly glacial, peryglacial, deundational,...
Abstract. Soils in Arctic regions currently enjoy attention because of their sensitivity to climate change. It is therefore important understand the natural processes and rates development these soils. Specifically, there a need quantify interactions between various landscape- soil-forming processes. Soil chronosequences are ideal experiments for this purpose. In contribution, we combine field observations, luminescence dating soil–landscape modelling improve test our understanding soil...
The tsunami deposits left by the 26 December 2004 in coastal zone of Thailand were studied within two months event and before any significant postdepositional changes could occur. sediment structure texture (grain size), as well its thickness spatial distribution, documented for 12 shore-perpendicular transects from areas various run up wave heights. thick 0.4 m located far 1.5 km inland. They composed mostly poorly sorted sand often consisted one to four normally graded, massive or...
ABSTRACT A 1:850 detailed map of the geomorphology Dynamisk Creek alluvial fan on Svalbard was produced based very high-resolution data collected using an unmanned aerial vehicle (UAV) in 2014. The documents features within surface (0.35 km2), emphasizing their relative temporal activity. Fluvial flows were most important geomorphological processes responsible for aggradation and modification surface. However, at present area is inactive (about 75% whole surface) stabilized by vegetation...
River discharge from partly glacier-covered catchments is controlled by its storage on various time scales and release ice snow during melt-out. These processes depend seasonal reactions to meteorological conditions, generating variable river magnitudes, including floods. Four types of meteorologically driven floods in were distinguished, depending the variations dominant water supply source type storage. four induced by: 1 – spring/summer snow-melt; 2 mid-summer 3 rainfall events, 4 föhn...
Samples of water from small tundra lakes located on raised marine terraces the eastern coast Petuniabukta (Ebbadalen, Central Spitsbergen) were examined to assess changes in chemistry that had occurred during summer seasons 2001–2003 and 2006. The unique environmental conditions study region include predominance sedimentary carbonate sulphate rocks, low precipitation values, an active permafrost layer with a maximum thickness 1.2 m. average specific electric conductivity (EC) values for...
