The presence of psychrophilic yeasts in supra- and subglacial sediments, ice meltwater collected from two glaciers the Italian Alps (Forni Sforzellina – Ortles-Cevedale group) was investigated. After incubation at 4 °C, sediments contained 1.3 × 103 to 9.6 CFU g−1. number yeast cells supraglacial c. 10–100-fold lower. A significant proportion isolated exhibited one or more extracellular enzymatic activities (starch-degrading, lipolytic, esterolytic, proteolytic pectinolytic activity) °C....
Abstract A distributed surface energy-balance study was performed to determine sub-debris ablation across a large part of Baltoro glacier, wide debris-covered glacier in the Karakoram range, Pakistan. The area is ~124km 2 . aimed primarily at analyzing influence debris thickness on melt distribution. spatial distribution physical and thermal characteristics calculated from remote-sensing (ASTER image) field data. Meteorological data an automatic weather station Urdukas (4022ma.s.l.), located...
Abstract. This contribution examines glacier changes on the south side of Mt. Everest from 1962 to 2011 considering five intermediate periods using optical satellite imagery. The investigated glaciers cover ~ 400 km2 and present among largest debris coverage (32%) highest elevations (5720 m) world. We found an overall surface area loss 13.0 ± 3.1% (median 0.42 0.06 % a−1), upward shift 182 22 m (3.7 0.5 a−1) in snow-line altitude (SLA), a terminus retreat 403 9 6.1 0.2 increase 17.6 0.20...
Abstract. Tourists and hikers visiting glaciers all year round face hazards such as sudden terminus collapses, typical of a dynamically evolving environment. In this study, we analyzed the potential different survey techniques to analyze Forni Glacier, an important geosite located in Stelvio Park (Italian Alps). We carried out surveys 2016 ablation season compared point clouds generated from unmanned aerial vehicle (UAV) survey, close-range photogrammetry terrestrial laser scanning (TLS). To...
Abstract. In the mountain regions of Hindu Kush, Karakoram and Himalaya (HKH) "third polar ice cap" our planet, glaciers play role "water towers" by providing significant amount melt water, especially in dry season, essential for agriculture, drinking purposes, hydropower production. Recently, most HKH have been retreating losing mass, mainly due to regional warming, thus calling assessment future water resources availability populations down slope. However, hydrology these high altitude...
The Karakoram Range is one of the most glacierized mountain regions in world, and glaciers there are an important water resource for Pakistan. attention paid to this area increasing because its remained rather stable early twenty-first century, contrast general glacier retreat observed worldwide on average. This condition also known as “Karakoram Anomaly”. Here we focus recent evolution within Central National Park (CKNP, area: *13,000 km 2 ) assess their status region with respect described...
Here three glacier surface area records (years 1975, 1999 and 2005) available for Aosta Valley (western Italian Alps) have been synthesized. The 1975 data collected by previous authors who compiled the first regional database. 2005 were computed here combining registered colour orthophotos with differential GPS (DGPS) field measurements. changes of 174 glaciers (those shared within data) calculated to describe recent evolution a representative subset glaciers. lost 44.3 km 2 during...
.This paper describes the recent evolution of Italian glaciers through an analysis all available terminus fluctuation data that authors have entered in a database (named GLAD) containing 883 records collected on from 1908 to 2002. Furthermore, representative subset (249 located Lombardy) was analysed regarding surface area changes.For fluctuations, were sorted by size classes according length. The showed during 20th century Alpine underwent generalized retreat, with one distinct and well...
The recent rapid mass loss of mountain glaciers in response to climate warming has been reported for high and low latitudes all over the Earth. paper analyses discusses evolution a representative glacierized group within Italian Alps, Piazzi—Dosdè, where small are experiencing considerable retreat shrinking. We analysed aerial photos calculate area geometry changes time window 1954—2003, glaciological geomorphological surveys were also performed. estimated change during 1954—2003 was —3.97...
The influence of some abiotic variables (pH, dry weight, organic carbon, nitrogen and phosphorous) on culturable yeast diversity in two distinct, but adjacent Alpine glaciers (Glacier du Géant, France, Miage Glacier, Italy) was investigated. In all, 682 strains were isolated identified by D1/D2 ITS sequencing as belonging to species the genera Aureobasidium, Candida, Bulleromyces, Cryptococcus, Cystofilobasidium, Dioszegia, Guehomyces, Holtermanniella, Leucosporidiella, Mrakia, Mrakiella,...
Abstract. Karakoram is one of the most glacierized region worldwide, and glaciers therein are main water resource Pakistan. The attention paid to this area increasing, because evolution its recently depicted a situation general stability, known as "Karakoram Anomaly", in contrast glacier retreat worldwide. Here we focused our upon within Central National Park (CKNP, newborn park region, ca. 12 162 km2 area) assess magnitude rate such anomaly. By means Remote Sensing data (i.e.: Landsat...
Abstract This study provides an estimate of fresh water derived from ice melt for the ablation areas glaciers in Central Karakoram National Park (CKNP), Pakistan. In CKNP there are ~700 glaciers, covering ~4600 km 2 , with widespread debris cover (518 ). To assess meltwater volume we applied a distributed model able to describe both debris-covered and debris-free ablation. The was calibrated using data collected field area validated by comparison field, independent used building model....
This study presents a map reporting valuable information on the cryosphere of Central Karakoram National Park (CKNP, largest protected area Pakistan and highest park in world). All is provided considering CKNP as whole, detail by dividing it into five basins (i.e. Shigar, Hunza, Shyok, Upper Indus, Gilgit). The glacier inventory reports 608 ice bodies covering 3680 km2 (∼35% area), with total volume ca. 532 km3. In addition, we modeled meltwater from ablation over period 23 July to 9 August...
Over the last decades, expansion of supraglacial debris on worldwide mountain glaciers has been reported. Nevertheless, works dealing with detection and mapping detailed analyses aimed at identifying temporal spatial trends affecting glacier cover are still limited. In this study, we used different remote sensing sources to detect map cover, analyze its evolution, assess potential remote-sensed image data. We performed our Ortles-Cevedale Group (Stelvio Park, Italy), one most representative...
Debris-covered glaciers represent a significant, increasing fraction of and can host plant life on their surface. The goal this work was to evaluate the suitability supraglacial debris as habitat for discuss its ecological biogeographic role. research carried out Miage Glacier (Mont Blanc massif, Western Alps, Italy). Vegetation cover sampled using regular sampling grid, recording species number individuals in 71 plots. Detailed glaciological parameters (surface temperature, thickness,...
We analysed the recent involution of glaciers in Bernina group (Italy), which are shrinking thus permitting a rapid enlargement forelands. delimited glacier outlines upon aerial photographs (1954 and 1981 stereo pairs through an optical system) orthophotos (2003 2007 digital imagines directly managed via GIS software). All obtained data were overlapped compared. The estimated area change during 1954–2007 was −36.5 ± 2.4% (−16.2 0.4 km2). changes sped up more recently; fact, 1981–1954 (27...
