Glacier dynamics, Glacier mass balance, Climate change, Glacial hydrology, remote sensing


Glacier mass balance, unlike the changes in length and area, is a direct method to ascertain the impact of climate change on the glaciers and establishes a linkage between glacier dynamics and climate change. The geological method of mass balance studies provides quantitative estimate of glacier loss at high temporal resolution, which is essential for understanding climate-glacier interaction processes and spatio- temporal variability of the glacier mass balance, even with only a small sample of observation points. The glaciological observations are complemented by results from the geodetic method to extend the mass balance measurements for better insights into the glacial dynamics. Recent advances, especially availability of precise laser altimetry data sets, Lidar and laser-derived DEMs acquired using UAVs, provide a new opportunity to assess glacier dynamics in otherwise inaccessible and rugged terrain. The symposium invites abstract on all above aspects of glacier mass balance.

Glacier dynamics, Glacier mass balance, Climate change, Glacial hydrology, remote sensing

Melt waters from glaciers provide much of the water supplies for agriculture and hydropower production. Sustained glacier retreats in response to climate warming and anthropocene will significantly reduce the contribution of glacier-melt to the streamflows in glaciated basins. The forecast of streamflows in glacier-fed streams thus requires an understanding of the process controlling glacier mass balance, glacier hydraulics, sediment dynamics and fluctuations in glacier geometry. Hazards associated with glaciers, largely controlled by glacial hydrology have necessitated the need for better understanding of glacial hydrology. Sudden bursting of glacier-dammed lakes and of water stored within glaciers – and mudflows associated with these events – has caused extensive damage in mountainous regions. This symposium invites abstracts on all above-mentioned issues.

Glacier dynamics, Glacier mass balance, Climate change, Glacial hydrology, remote sensing

Glaciers are sensitive and direct indicators of climate and its fluctuations. The dynamic behaviour of glaciers and its sensitivity to climate plays an important role in determining the time dependent evolution of mass balance and runoff changes in mountainous regions. Standard glacier parameters include mass balance and the glacier length determines the position of terminus (snout position) and annual difference between net gain (accumulation) and loss (ablation). Fluctuations in snow line/ Equilibrium line altitude, Equilibrium Line Altitude and accumulation area ratio of aa glacier provides an immediate response of glaciers to climate change. This symposium will address glacial parameters those can be used as indicators of temperature and precipitation variation at local and regional scale and inter alia provide a direct indication of the health of a glacier.

Glacier dynamics, Glacier mass balance, Climate change, Glacial hydrology, remote sensing

Cryosphere encompasses all the Earth's icy regions— including snow, glaciers and permafrost. The above-surface part of the cryosphere occupies around one sixth of the Earth's surface, and is located in places that are generally very remote, rugged, and in challenging climatic conditions. Cryosphere is therefore well suited to the use of remote sensing techniques, especially those operated from space borne platforms. The availability of ICESat, CryoSat and AMSR-E data has given boost to the cryospheric studies. This symposium will address recent advancements in remote sensing and image processing for climatic behaviour modeling from cryospheric measurements.

Glacier dynamics, Glacier mass balance, Climate change, Glacial hydrology, remote sensing

Understanding the stability and dynamics of glaciers is critical for predicting the future of glaciers. Glacier dynamics are driven by the interplay between the topography, temperature and basal conditions beneath the ice. Cryosphere monitoring and modelling approaches are closely interconnected thereby the data from monitoring systems are routinely used to calibrate and validate numerical glacier dynamics models. Glacier dynamics models relating temperature with glaciers terminus records coupled with high resolutions climate models have recently been used to assess changes in glacier mass balance and associated impacts under changing climate. This symposium will address informations available in past few decades from satellite and other monitoring systems together with the advancement in the computing hardware to understand complex behaviour of glaciers at fine spatial and temporal scales.
