ABSTRACT Austre Lovénbreen is a 4.6 km 2 glacier on the Archipelago of Svalbard (79° N) that has been surveyed over last 47 years in order to monitor particular evolution and associated hydrological phenomena context nowadays global warming. A three‐week field survey during April 2010 allowed for acquisition dense mesh ground‐penetrating radar (GPR) data with an average 14 683 points per (67 542 total) surface. The profiles were acquired using Mala equipment 100 MHz antennas, towed slowly...
ABSTRACT We address the evolution of a proglacial hydrographic network under influence icings over small Arctic glacier forefield in context retreat. The newly deglaciated area allows glacial rivers to carve new channels as fine‐grained sediment is exposed. main outlet flow from one channel another controlled by years. research methodology involves analyzing optical camera images for qualitative observations morphological evolutions and LiDAR data quantitative estimates icings' volume well...
Landslide activity is expected to increase as climate change reduces mountain slope stability. High-Arctic regions like Svalbard are critical for studying dynamics in a changing climate, especially due arctic amplification effects. Despite the significance of Arctic research, empirical evidence these often lacking absence long-term, high-resolution terrain data necessary assess impact meteorological conditions on landscapes severely affected by change. Bridging this gap vital comprehending...
Arctic regions are known to be places where climate shift yields the most visible consequences. In this context, glaciers and their environment highly subject global warming effects. New dynamics observed behaviour of arctic systems (such as glaciers, moraines, beaches, etc.) changes at rates over yearly observations. According recent works on change impacts cryosphere, short/violent events recently one characteristic these changes. As a consequence, an accelerating rate glacial pro-glacial...
Abstract Comprehensive studies of water resources systems require integration modeling tools and data associated with individual processes. An object‐oriented approach is presented here that associates ground models based upon the analytic element method (AEM) geographic information system (GIS) geodatabase features using an AEM Model Interface. Each aquifer object contains a prescribed geometry, mathematical representation in AEM, GIS hydrogeologic data. The synergistic understanding...
Abstract In the context of glacier retreat and increased precipitations, Arctic basin slopes are subject to stress leading visible transformations. this work, subsurface features a small mapped using ground‐penetrating RADAR. combination with surface topography data, eight transects were surveyed ranging from areas furthest current extent still in contact glacier. This allowed for reconstitution successive stages ice‐cored go through when glaciers retreat. It appears that evolve thick...
Development of a conceptualization hydrogeologic system serves as the basis groundwater modeling. While existing data models are designed to store information, none is capture its conceptual view. This study addresses this need by presenting new object-oriented Conceptualization Groundwater Data Model that represents series aquifer layers with defined properties and water boundary conditions. A case presented develops view beneath Konza Prairie. single used support across technologies finite...
Abstract Methods for assessing the contribution of proglacial moraine into water budget an Arctic glacier are investigated. High spatial resolution elevation models at different seasons needed to estimate volume ice and snow accumulated during winter in this part catchment basin released rivers melting season. Lidar currently provides highest generation digital ( DEM s). This paper considers complementary use a commercial off‐the‐shelf DJI Phantom 3 Professional unmanned aerial vehicle UAV )...
The change of Austre Lovénbreen, a 4.5 km2 land-based glacier along the west coast Spitsbergen, is investigated using geodetic methods and mass balance measurements over 1948–2013. For 2008−2013, annual balances computed on 36-stake were obtained, in addition to reconstructed from neighbouring glaciers, Midtre Lovénbreen (1968−2007) Brøggerbreen (1963−1967). mean rate retreat for 1948–2013 −16.7 ± 0.3 m a−1. Fluctuations area (1948–2013 mean, −0.027 0.002 a−1) showed slowing as recedes...
ABSTRACT The volume variation of a glacier is the actual indicator long term and short evolution behaviour. In order to assess Austre Lovénbreen (79° N) over last 47 years, we used multiple historical datasets, complemented with our high density GPS tracks acquired in 2007 2010. improved altitude resolution recent measurement techniques, including phase corrected LiDAR, reduces time interval between datasets for subtraction compute mass balance. We estimate sub-metre elevation accuracy most...
Abstract A phosphorus budget for a single crop was prepared 685‐ha semi‐intensive shrimp farm that consistently has produced about 3000 tonnes/yr of black tiger prawn, Penaeus monodon . Phosphorus inputs were stock, 0.31 kg/ha; triple superphosphate, 1.38 incoming water, 25.8 and feed, 65.3 kg/ha. outputs harvested shrimp, 5.43 kg/ha, outflow water exchange draining, 42.7 The high clay‐content soil in pond bottoms adsorbed 45.2 kg/ha phosphorus. Water taken from released back into the same...
A three week field survey over April 2010 allowed for the acquisition of 120 Ground Penetrating Radar (GPR) profiles, adding to a 40 km long walk across an Arctic glacier. The profiles were acquired using Malå equipment with 100 MHz antennas, walking slowly enough record 2.224 μs trace every 30 cm on average. Some acquisitions repeated 50 or 200 antenna improve data quality. GPR was coupled GPS system position traces. Each profile has been manually edited standard processing, pick reflection...
ABSTRACT Due to poor weather conditions including common heavy cloud cover at polar latitudes, daily satellite imaging is not always accessible. Nevertheless, fast events rainfall inducing floods appear as significant in the ice and snow budget while being ignored by based studies since slower sampling rate unable observe such short phenomena. We complement imagery with a set of ground autonomous automated high resolution digital cameras. The recorded oblique views, acquired 3 images per...
Abstract In the general context of global warming, cryosphere appears as an environment that exhibits a strong sensitivity to climate variations. Overall, glacier systems are now known be reliable indicators trends. Although dynamics subject international monitoring networks, periglacial environments much less observed. However, these newly deglaciated areas get wider since glaciers retreating, and their become increasingly significant. The observed increase in water fluxes, temperature...
The Arctic region has experienced significant warming during the past two decades with major implications on cryosphere. causes of amplification are still an open question within scientific community, attracting recent interest. goal this study is to quantify contribution atmospheric circulation temperature variability in Atlantic–Arctic at decadal intra‐annual timescales from 1951 2014. Daily 20th Century reanalyses geopotential height anomalies 500 hPa were clustered into different weather...
