No Longer Anchored, Antarctic Ice Stream Surges to Sea--Under-Ice Sub Finds Ridge That May Have Held Back Pine Island Glacier（图）
Antarctic Ice Stream Sea Ice Sub Back Pine Island Glacier
2010/6/22
Satellite tracking has shown that the Pine Island Glacier, one of Antarctica's largest ice streams, is accelerating and thus contributing a growing share of the melt water raising sea levels worldwide...
Forecasting temperate alpine glacier survival from accumulation zone observations
Forecasting temperate alpine glacier survival accumulation zone observations
2010/2/3
Temperate alpine glacier survival is dependent on the consistent presence of an accumulation zone. Frequent low accumulation area ratio values, below 30%, indicate the lack of a consistent accumulatio...
Reduced glacier sliding caused by persistent drainage from a subglacial lake
Reduced glacier sliding persistent drainage subglacial lake
2010/2/3
We present velocity observations of a glacier outlet in Vatnajökull, Iceland, deduced from interferometric SAR (InSAR) data obtained during the ERS1/2 tandem mission in 1995–2000. More than a 50%...
Recent variation of the Las Vacas Glacier Mt. Aconcagua region, Central Andes, Argentina, based on ASTER stereoscopic images
Las Vacas Glacier Mt. Aconcagua region Central Andes ASTER stereoscopic images
2010/1/28
This work presents the results of the ASTER stereoscopic image processing to calculate the volume changes of Las Vacas Glacier. The processing of medium resolution satellite images (ASTER level 1A – p...
Mass balance evolution of Martial Este Glacier, Tierra del Fuego (Argentina) for the period 1960–2099
Mass balance evolution Martial Este Glacier Tierra del Fuego
2010/1/28
The Martial Este Glacier in southern Tierra del Fuego was studied in order to estimate the surface mass balance from 1960 until 2099. For this reason a degree-day model was calibrated. Air temperature...
Regional-scale GIS-models for assessment of hazards from glacier lake outbursts: evaluation and application in the Swiss Alps
Regional-scale GIS-models glacier lake outbursts evaluation and application the Swiss Alps
2009/12/10
Debris flows triggered by glacier lake outbursts have repeatedly caused disasters in various high-mountain regions of the world. Accelerated change of glacial and periglacial environments due to atmos...
Quantifying changes and trends in glacier area and volume in the Austrian tztal Alps(1969-1997-2006)
changes trends glacier area Austrian tztal Alps
2010/2/3
In this study we apply a simple and reliable method to derive recent changes in glacier area and volume by taking advantage of high resolution LIDAR (light detection and ranging) DEMs (digital elevati...
Characterizing contributions of glacier melt and groundwater during the dry season in a poorly gauged catchment of the Cordillera Blanca (Peru)
Characterizing contributions glacier melt dry season Peru
2010/1/28
The retreat of glaciers in the tropics will have a significant impact on water resources. In order to overcome limitations with discontinuous to nonexistent hydrologic measurements in remote mountain ...
Environmental records from temperate glacier ice on Nevado Coropuna saddle, southern Peru
Environmental records temperate glacier ice Nevado Coropuna saddle
2010/1/28
We investigated past climate variability and the zonal short and long-range transport of air masses in tropical South America using chemical, isotopic and palynological signals from a 42 m-long ice co...
Glacier volume response time and its links to climate and topography based on a conceptual model of glacier hypsometry
Glacier volume response time climate topography conceptual model glacier hypsometry
2010/2/3
Glacier volume response time is a measure of the time taken for a glacier to adjust its geometry to a climate change. It has been previously proposed that the volume response time is given approximate...
Phosphatase activity and organic phosphorus turnover on a high Arctic glacier
Phosphatase activity organic phosphorus high Arctic glacier
2010/1/20
Arctic glacier surfaces harbour abundant microbial communities consisting mainly of heterotrophic and photoautotrophic bacteria. The microbes must cope with low concentrations of nutrients and with th...
Increased rate of acceleration on Pine Island Glacier strongly coupled to changes in gravitational driving stress
Increased rate acceleration Pine Island Glacier gravitational driving stress
2010/2/3
Pine Island Glacier, Antarctica, has been undergoing several related changes for at least two decades; these include acceleration, thinning and grounding line retreat. During the first major ground-ba...
Exploring uncertainty in glacier mass balance modelling with Monte Carlo simulation
uncertainty glacier mass balance modelling Monte Carlo simulation
2010/2/4
By means of Monte Carlo simulations we calculated uncertainty in modelled cumulative mass balance over 400 days at one particular point on the tongue of Morteratsch Glacier, Switzerland, using a glaci...
Identification of glacier motion and potentially dangerous glacial lakes in the Mt. Everest region/Nepal using spaceborne imagery
glacier motion potentially dangerous glacial lakes spaceborne imagery
2010/1/4
Failures of glacial lake dams can cause outburst floods and represents a serious hazard. The potential danger of outburst floods depends on various factors like the lake's area and volume, glacier cha...
The equilibrium flow and mass balance of the Taku Glacier,Alaska 1950–2006
equilibrium flow mass balance Taku Glacier
2010/2/4
The Taku Glacier, Alaska has advanced 7.5 km since the late nineteenth century, while all other primary outlet glaciers of the Juneau Icefield are in retreat. The Juneau Icefield Research Program has ...
